Introduction: Security service provider

In 2019, the European Court of Justice (ECJ) asked whether property rental platform AirBnB should be classified as a ‘lodging corporation’ or whether it is a ‘sharing economy platform’.Footnote ¹ In this case, brought by the French Tourist Agency, the ECJ found in favour of AirBnB and confirmed that the platform is not a property company but an information company. This verdict had consequences for AirBnB’s regulation, and its liability for licensing and taxation. In brief, the court found that AirBnB is a ‘mere connector’, which means that it carries ‘no responsibility’ for sector-wide standards like consumer protection and safety.Footnote ² Around the same time, European Police Agency Europol outlined its 2020+ Vision, and set out its ambition to become ‘the EU criminal information hub making full use of data from an extensive network of partners’, and to become ‘a platform for European policing solutions’.Footnote ³ This vision is accompanied by new types of technology infrastructures, like Ma3tch, that allow European national police databases to connect and communicate without central integration. This also has consequences for regulation, as the lack of centrally integrated databases means that EU privacy law does not centrally apply. As one European law enforcement official put it in a public meeting: ‘We are a service provider’.Footnote ⁴

This article proposes that the imaginary and infrastructure of the platform economy – as exemplified in the AirBnB case – is also emerging in the security practices of a range of Western security institutions in recent years – as exemplified in the Europol 2020+ approach. There is a deep analogy at work between the AirBnB case and the Europol vision. Like digital platform companies, security authorities sometimes seek to position themselves as neutral intermediaries and technical facilitators, rather than influential powers. Instead of claiming supranational authority and competence, some (European) security institutions are presenting themselves as ‘mere’ information services, connectors, and information hubs. As such, these security institutions emulate the discourses and practices of digital platforms that connect and commercialise the contributions of end-to-end users in the online environment. Like the ‘information society service’ of AirBnB, these security practices work through the facilitation and connection of decentred participants. They involve a discursive minimisation of power and enable regulation avoidance.

If security authorities are thought to exist by virtue of claiming power and speaking security,Footnote ⁵ this minimisation of the own role and the emphasis on ‘mere’ facilitation seems surprising and something that requires more explanation. Notions of mundane and material security practices,Footnote ⁶ for example as expressed in the idea of ‘little security nothings’, go some way towards analysing everyday and seemingly modest self-representations of security authorities.Footnote ⁷ The modest positioning of Europol is also understandable in the context of its limited role in a European context, whereby police matters remain primarily national affairs. Yet this does not fully explain the way in which the platform metaphor and model has become so crucial to the discourses and technical infrastructures of transnational security institutions like Europol and others. Nor do these elements explain the ways in which transnational security institutions adopt technical practices that emulate key technologies and infrastructures of digital platform companies.

This article asks: why and how do transnational security institutions depict and deliver their services in terms drawn from discourses and practices of internet platforms? The paper draws out the analogy between discourses and practices of the platform economy and what I call platform security. I do not claim that platform security and platform economy are exactly the same – yet I argue that we see more than a superficial parallel here. There is a deep analogy at work between the way that security institutions represent themselves and organise their technical practices, and the ways in which digital platform companies represent themselves and organise their technical practices. I use the term ‘analogy’ here to compare digital company practices and security practices for ‘the purpose of explanation or clarification’,Footnote ⁸ and to explore how critical questions concerning digital platforms may be applied to security practices. Digital platform companies reorganise collective responsibility for sectors including news, transport, and urban housing. Their imaginaries and infrastructures raise questions concerning regulation, responsibility, accessibility, and privacy protection, among other issues.Footnote ⁹ The analogy between platform economy and platform security enables us to ask similar questions about transnational security practices: how they reorganise collective responsibility and regulation and challenge traditional modes of governance.

This paper argues that the analogy between platform security and platform economy comprises both discursive representation and technological practices. I use the term imaginaries to explore analogies in discursive representation, and the term infrastructures to unpack the material analogies between digital platforms and security practices.Footnote ¹⁰ Imaginaries are understood as ‘collectively imagined forms of social life and social order’ that help shape and enable discourses and policy outcomes.Footnote ¹¹ They entail ‘distinctive … visions of desirable futures driven by science and technology’.Footnote ¹² In addition, the concept of infrastructures is useful to analyse the material-technical aspects of platform imaginaries.Footnote ¹³ The focus on infrastructure draws attention to the material organisation and technical properties of platforms. It helps analyse the affordances or ‘dispositions’ encoded into technologies, understood as their propensity to enable or constrain possibilities.Footnote ¹⁴

In order to develop the argument, the paper first fosters a discussion between critical security studies on the one hand, and the literature in media studies that analyses digital platforms as a metaphor and model of power, on the other. Then, I zoom in on the imaginaries and the infrastructure of the platform economy, as they have been identified in the literature. This is followed by a short note on method. Empirically, the paper draws on examples from fieldwork in the realm of European counterterrorism, with a specific focus on institutions and practices that aim to counterterrorism financing (CTF). The final section of the paper raises the question how platform security impacts public values and raises critical questions about security practices in Europe.

Critical security studies meets platform studies

Critical security studies offers good starting points for thinking through a platform model of security; from both a rhetorical and a material-technical perspective. Within the literature on European security, Mai’a Davis Cross was one of the first authors to analyse EU security as a hub-and-spoke model whereby knowledge networks play a crucial role.Footnote ¹⁵ This literature has shown how EU security is dependent on the creation and connection of digital databases.Footnote ¹⁶ Authors have critically analysed the new EU approach of digital ‘interoperability’, and shown how it dislodges existing accountability structures.Footnote ¹⁷

Furthermore, literatures in critical security studies have analysed how ubiquitous digitisation and Artificial Intelligence (AI) have impacted security politics and practices of warfare and sovereignty.Footnote ¹⁸ Information dominance is considered crucial to modern warfare, meaning that the digitisation and acceleration of information are core to the military revolution. A modern tank, for example, is not simply a military vehicle but also a platform for battlefield information and situational awareness.Footnote ¹⁹ This literature has extensively discussed the importance of data analytics to modern security practices.Footnote ²⁰ With the role of Big Tech companies like Google in data-driven battlefield targeting and experimentation, Marijn Hoijtink signals ‘a new regime of warfare’.Footnote ²¹ Yet, with some exceptions, this literature has not really engaged with the question of the relation between the modern platform economy (of Google, Uber, AirBnB) and contemporary security practice.Footnote ²² That is surprising, because the modern ‘Big tech’ companies affect all aspects of contemporary life, including the ways in which security is imagined, practiced, and experienced.

In a different field, there is a burgeoning literature about online digital platforms and the ways in which they transform social, economic, and cultural practices.Footnote ²³ This literature shows that the platform economy impacts every aspect of everyday life, from the way we interact with friends to the way we consume foods; from the way in which sexual encounters take place, to the way in which we travel.

As this literature has extensively shown, platform power profoundly challenges public values. Platforms like Facebook and Uber ‘claim to be mere connectors, carrying no responsibility for the sector as such’.Footnote ²⁴ Yet their imaginaries and infrastructures change whole sectors and challenge the checks and balances that have been historically built to safeguard the quality of, for example, public transport, including ‘consumer protection, passenger safety, and inclusiveness’.Footnote ²⁵ This is powerfully illustrated in the AiRBnB case with which we started this paper which deliberately challenges regulation of the urban rental market, including licensing, taxation, and consumer protection, through its infrastructural form of a global ‘information intermediary’.

Literatures on platforms, with some exceptions, have not paid much attention to the security roles of Big Tech platforms, and the ways in which practices of platform companies contribute to militarism and warfare.Footnote ²⁶ This is surprising, because platform companies and technologies are crucial to modern warfare and security practices. Planqué-van Hardeveld enumerates three clusters of security roles that are played by Google, ranging from Google’s involvement in AI technologies for national defence to the online policing of digital content with possible terrorist intent.Footnote ²⁷ Hoijtink uses the term ‘platform warfare’ to theorise the ways in which digital platforms and modern warfare are increasingly interrelated.Footnote ²⁸ The most important way in which literatures on digital platforms have engaged with questions of security, is through the study of content moderation.Footnote ²⁹ Social media platforms like Twitter, Instagram, Facebook, but also gaming sites and smaller platforms, are required (by law or regulation) to police their servers for material that may be criminal or terrorist in content, and take actions to remove or render such material invisible. This authorises big tech platforms to make important security decisions (about taking content offline, closing accounts) that makes them effective ‘co-producers’ of security.Footnote ³⁰ In this manner, content moderation has become a crucial anchor of governance of platform power.

The next sections further discuss the literature on platform studies in order to tease out some core elements of platform imaginaries and platform infrastructures. This will be the basis of critical enquiry into the security imaginaries and infrastructures that we have identified through fieldwork.

Platform imaginaries and infrastructures

This section discusses the literature on platform studies and draws out its relevance for security studies. The purpose here is not to offer a full overview but to distill several elements of platform imaginaries and infrastructures that act as thematic guides to the empirical analysis that follows.

Though the literature on platforms does not offer one definition of what a platform is and how it works, it broadly argues that the digital platform is a mode of power. As Christofari shows, the platform is an important metaphor and model of power, rather than purely an objective description of technical infrastructure or company model.Footnote ³¹ Different aspects of platform power are discerned. For Culpepper and Thelen, it is the ‘tight, even intimate, connection to their users’ that underpins ‘distinctive form of power’ of large platforms, which have unprecedented ‘scale and influence’.Footnote ³² Another approach stresses that platforms are ‘active political actors in their own right’ because they have considerable ‘opinion power’ in shaping how platform users retrieve information and engage with news.Footnote ³³ Platforms make important choices about the way in which information is curated, shared, connected and made (in)visible. These choices are inscribed in the technical affordances of platforms and, as such, shape and constrain the behaviour and options of users. For Aradau and Blanke then, the crux of platform power is that it materially constitutes ‘algorithmically constituted relations’.Footnote ³⁴ They argue that platform power is not (just) about platforms’ abilities to ‘conquer new territories and integrate new populations’ but also about new modes of algorithmic classification that govern populations.Footnote ³⁵ The following discussion of platform imaginaries and infrastructures builds on the core notion of the digital platform as a mode of power.

Methodological note

The remainder of this paper teases out the analogy between platform imaginaries and infrastructures on the one hand, and contemporary security practices on the other. The empirical parts of the paper are based on interviews and participant observations in the broad field of CTF in Europe between 2016 and 2022. Empirical examples are drawn from observations and documents of several security institutions, including European Police Agency Europol; the Financial Action Task Force (FATF), that is responsible for developing transnational regulation and guidelines in the field of Anti-money Laundering and Counterterrorism Financing; and the public–private datasharing initiatives centring around terrorism financing, including the Dutch Terrorism Financing Platform (TF Platform) and British Joint Money Laundering Intelligence Taskforce (JMLIT). These actors are crucial transnational institutions/authorities, with significant impact on the shape of national law and regulation concerning terrorism and terrorism financing, while largely remaining beyond political purview.

Analytically, the method was inductive: the analogy to platform imaginaries and infrastructures was not a primary research objective of the fieldwork, but arose as a theme throughout observations and interviews. The methodological approach in the larger project – of which this paper is a part – was to ‘immerse’ ourselves into the life-worlds of financial security practitioners, ‘learning the daily language, plotting the struggles, … understanding the deep well of commonsense beliefs’.Footnote ⁵⁵ This entailed approaching the professional field without judgement.Footnote ⁵⁶ Though there was a thematic focus for the fieldwork, there was also space for new themes to arise inductively by ‘travel[ling] back and forth between the part and the whole, experience and text, fieldwork and theory’.Footnote ⁵⁷ It is in this ‘travelling back and forth’ that the platform analogy took shape: I started to recognise a theme when interviewees regularly described their work in terms of facilitation, technical assistance and building connectivity, while minimising their own role. Once I started noticing the platform metaphors and models in professional security discourses – from 2017 onwards – I remained attentive to the theme, and steered interview questions in this direction.

All examples are drawn from security practices relating to countering terrorism, terrorism financing and financial intelligence sharing, which was also the focus of our larger research project.Footnote ⁵⁸ Though the focus on CTF seems to address a very specific (and perhaps not very significant) problem-space, it is in this empirical practical domain that we find advanced experimental security and policing techniques at the limits of law.Footnote ⁵⁹ The political urgency of CTF, and its data-led nature, produces security practices that push existing and institutional and legal boundaries. Consequently, this problem space is a relevant site of empirical observation, with the potential to reveal the cutting edge of security practices and imaginaries.

Platform security imaginaries

This section focuses on the ways in which the platform imaginary manifest itself in the professional self-representations and justifications of security actors. Core elements of the platform imaginary, as identified above, include an emphasis on neutrality and decentred connectivity. In addition, the platform imaginary gives rise to new organisational forms whereby decentralised data are connected and curated in particular ways. This section shows that, as with the platform economy, the socio-technical imaginaries of ‘security platforms’ help efface or disavow their active roles in curating particular connections and in selecting, shaping, and presenting content.

During fieldwork at a range of security institutions, interviewees actively sought to put their work into a modest perspective, emphasising their lack of executive power, and foregrounding their mediating and facilitating role. For example, in our visit to the FATF secretariat, it was emphasised that the secretariat has a subservient role, that it is at the service of member states, that it does not have an independent authority to shape agendas or deliver policy content. Security practitioners seek to present their work as primarily intermediating the work of sovereign authorities, or facilitating connections between decentred investigations or databases. Such self-representations are not simply a pose, but are themselves productive of specific security practices and technologies. It is important to analyse on their own terms the arguments and justifications that policy practitioners put forward about their work, which tells us something about ‘the concern for the good that persons are moved by’.Footnote ⁶⁰ An interview or public event confronts the security professional with ‘an imperative of justification’ – and I assume that such justifications tell us something important about the positioning of organisations and their sense of doing things well.

Take the FATF, an important international organisation that sets standards for governance, regulation, and best practices in the field of AML/CFT. The FATF as an organisation emphasises its facilitating and even subservient role vis-à-vis its members. A lot of its work is cast in terms of technical assistance and voluntary mutual evaluations.Footnote ⁶¹ Interviewees emphasise that they do not have ‘a mandate for technical guidance’ but that this always happens under the auspices of a presidency by a particular country.Footnote ⁶² For example, a representative of the secretariat, when asked about his views on whether a particular type of public-private data-sharing is a model for the future, said that he ‘does not have any views’.Footnote ⁶³ In this manner, the secretariat of the most prominent organisation in developing standards and best practices for AML/CTF, sought to express that this is a member-driven organisation, that in itself lacks a strong agenda or strong views, but that acts in the service of its member states’ agendas and priorities. Yet at the same time FATF plays an incredibly important role in the ways in which member states practice financial rule making, and is closely involved in the design of national law and regulation.

In another example, in our fieldwork at a European police organisation, a lot of emphasis was placed on their facilitating and interconnecting role, especially where it concerns cross-checking police data transnationally. This Europol Internet Referral Unit (IRU), which has the mandate to ‘detect and refer the core disseminators of terrorist propaganda’.Footnote ⁶⁴ IRU’s mode of operation is one of close connection with and facilitation of, private company decisions to remove suspect content. IRU does not itself remove online content or police the digital public sphere, but it works with platform companies and on the basis of company ‘Terms of Service’ documents in order to suggest content removals. The security decision to remove content or close accounts remains a private one, yet it is facilitated and technically supported by the Europol. Companies themselves identify, select, search, interpret suspicious transactions; they monitor, regulate, restrict, and expel client groups. Here, the modus operandi is one of technical enforcement and privileged communications with platform companies themselves. As one interviewee put it, ‘you have the terms of service and then you have the capacity of the company to enforce these terms and services and that’s where it’s complicated’.Footnote ⁶⁵ The police agency does not collect or store or retain police data centrally, but emphasises its facilitating role:

IRU works with and through the platform model of the companies themselves; offering technical support in terms of curation, presentation, and translation. In these practices of countering extremism online, we see a positioning of law enforcement as facilitator of company removal processes and connector of commercial databases, which has parallels with the socio-technical imaginary of the platform.

In other instances, we observed a socio-technical imaginary of being the technical connector and digital node in the field of European counterterrorism. One interviewee described how, in the wake of the Bataclan attacks of 2015, the European police agency played a pivotal role in connecting police data across borders. In this context, the interviewee notes, the European police agency was ‘not a driver’ for more data exchange, but a technical facilitator with the capacity to handle the data:

In this sense, the interviewee emphasises the technical capability and connectivity of the police agency. At the same time, the role of the police agency is understood in terms of analytical support, connecting information, providing leads and suggestions.

In the context of a discussion about the analytical work of the police agency, there was mention of the production of a ‘beautiful report’, understood as a compelling presentation to be handed to the frontline police organisation to work with. We questioned the interviewee on this notion of the ‘beautiful report’: what analytical work is being done here? The interviewee was talking about the complexity of cross-matching a multitude of data points, including financial trails, GPS signals, geospatial locations, car number plates, personal information. To make such information and analytical hypotheses presentable to frontline police units (in a nationally sovereign context), the interviewee notes,

Indeed, ‘sometimes when you have big dataset with a lot of hits, ... [a suspect] appears in this one, this one, this one, phone, … name, bank account, then it goes all over the place and then it makes a report impossible to understand’.Footnote ⁶⁹ In such a case, a ‘beautiful report’ can be a solution,

The example of the beautiful report illustrates how European law enforcement understands its task in terms of the presentation, connection, and digitisation of information – not unlike the work that platforms do in the digital economy.

Transnational institutions like FATF and Europol use expressions that minimalise their own positions and represent themselves as mere facilitators. They seem to disavow power. Despite these modest self-descriptions, however, both Europol and FATF are powerful organisations in the contemporary security landscape, especially as they drive forward agendas for sharing and analysing financial and social media data in the name of countering terrorism. Like platform companies, their power is lodged in the ways in which they curate content and digitally analyse, present, and visualise data. The significance of the ‘beautiful report’ is that it offers particular data curations that are made readable and compelling for particular courses of action, while appealing to a mere technical and aesthetic ordering of data. Just like the connection and curation practices of social media platforms, the ‘beautiful report’ of the police agency does more than neutrally present datafied content that is collected or delivered by others. Instead, data are curated, selected, presented, prioritised, and analysed in ways that make particular narratives and actions plausible.

Platform security infrastructures

The platform is simultaneously an imaginary and a technology. Put differently, the imaginary of the platform, as a neutral intermediary and connector, enables and is shaped by particular technological choices and operations. As discussed above, two technological features typify platform infrastructure: first, the way in which modes of decentralised connectivity enables avoidance of or withdrawal from regulation. Second, the way in which the programmability of platforms provides the infrastructure basis on which other applications and businesses run – generating ‘lock-in’ effects. This section offers several empirical examples that show how contemporary security actors seek to build security infrastructures inspired by a platform model, similarly generating avoidance of regulation and lock-in effects. How do the two elements of platform infrastructure (decentralised connectivity and programmability) play out relation to security technologies? How do these technological models affect the ways in which responsibility is claimed or denied in relation to security practices?

Consider the ways in which European Financial Intelligence Units (FIUs) exchange information transnationally.Footnote ⁷¹ Financial transaction data are particularly privacy sensitive because they have the capacity to reveal ‘information about individuals’ activities, purchases and geographical movements’, which can be used to derive ‘sexual orientation, health status, religious and political beliefs’.Footnote ⁷² Within the EU context, sharing financial transactions data is increasingly done through sophisticated platform infrastructures, that promise connectivity coupled with decentralised data ownership, and thus avoid the need to integrate financial databases.

An important example here is Europe’s FIU.NET, which interconnects the databases of national FIUs. FIU.NET does not integrate national databases, or transfer them wholesale to a European server. Instead, it renders national databases interoperable through a hit/no hit system called Ma3tch, so that it can be known whether data on a suspect are held on the database of a sister organisation (see Figure 1). It allows the FIU investigators to ‘follow the lead’ of social network analysis beyond the national database, without requiring supranational integration of databases. Mat3ch technology supposedly shapes ‘a virtual enterprise and information architecture without infringing upon local governance, privacy, security confidentiality’.Footnote ⁷³ It works as a decentralised computer network that allows data requests to partner institutions without sharing personal data: through a hit/not hit system, it is possible to assess whether data about a subject are or are not held by a partner institution. As an online propaganda film of the technology puts it: ‘When FIUs exchange sensitive information via FIU.net with each other, the data is only stored in the FIU net database at premises of the FIUs involved. There is no central database in Europe’.Footnote ⁷⁴

Figure 1.

Still from Ma3tch Video, see: https://vimeo.com/145121509.

Mat3ch offers a ‘decentralised information oriented architecture’ whereby ‘information owners’ retain ‘full governance over the information they connect to the system’.Footnote ⁷⁵ Through a process of layering whereby personal data are ‘virtualised’, the comparison, standardisation and exchange of data are enabled while ‘guarantee[ing] local autonomy’ and retaining ‘local data storage’.Footnote ⁷⁶ Mat3ch and similar technologies do not entail the creation of an integrated, transnational database at European level, as privacy watchdogs have feared of an EU-FIU. But they do enable ‘virtual information integration … without the need to bring the information physically together’.Footnote ⁷⁷

Yet Mat3ch entails a significant acceleration of transnational data exchange, with possible governance implications. Several factors about Mat3ch technologically-enabled platformed intelligence exchange are crucial: first, it can be (near) instantaneously and thus circumvents cumbersome and time-consuming Mutual Legal Assistance (MLAT) request, that are traditionally the way in which security authorities exchange personal data. As Mat3ch filters can operate continuously and instantaneously, they facilitate exchange of personal data that is fundamentally different from the traditional, cumbersome work of the MLAT. Second, data remain decentrally stored yet they are rendered communicable – in other words, the Ma3tch technology avoids the need for an integrated FIU database. An integrated EU-FIU database was a dream of European integration that has been deemed politically unrealistic. However, the mode of platform security as exemplified in Ma3tch evades the need for a central European database, with central supranational checks and balances. In this sense, Ma3tch is an example of the way in which data infrastructure effects the avoidance of EU central privacy regulation, precisely because databases are not centrally collected and stored.

Another and final example of new security infrastructures with strong parallels to the platform economy, is provided by the ways in which private financial institutions and police authorities collaborate to CTF through novel quasi-juridical forms such as a ‘Taskforce’ or a ‘Platform’. For example, the Dutch TF Taskforce and the British JMLIT are new organisational forms of public-private partnerships, that make it possible for police authorities to directly request information on named ‘persons of interest’ from financial institutions. Such collaboration takes place at the limits of law and through innovative ‘techno-legal gateways’.Footnote ⁷⁸ These platforms allow the proactive search of information on named ‘persons of interest’ who are however not necessarily suspects in a police investigation.Footnote ⁷⁹ As with Mat3ch, the technical form of these platforms is different from an integrated database: it revolves around decentralised connectivity whereby bank and police databases are carefully kept separate. Queries from police are made sharable with bank personnel – sometimes in very low-tech fashion. For example, bank and police operatives may meet in person to share names and discuss files. In this manner, databases are not integrated but remain separate, while connectivity is made through interpersonal or anonymised technical means.Footnote ⁸⁰ When this results in a hit, banks follow established routes of making a suspicious transaction report to the national Financial Intelligent Unit, which is the regular legal route for such reports. Police authorities would not otherwise have access to financial transactions data from private banks, unless they deposit a formal data-request within an ongoing investigation into a designated suspect, or when they are alerted through an FIU.

In sum, decentalised but interconnectable databases are emerging as a key technical form through which security practices operate. Taken together, this type of security infrastructure has major consequences for responsibility and regulatory control, just as in the AirBnB example. At the same time, because FIU.net and Ma3tch are housed at Europol, these technologies generate specific lock-in effects that strengthen Europol’s platform power.

Conclusion: Platform security and public values

This paper has argued that there is an emerging mode of platform security that, akin to platform economy, exercises power through technical connectivity while disavowing power. Media studies research has shown how public values are challenged and reworked through platforms’ technical choices, programmability and (lack of) responsibilisation. Platform companies like Uber and AirBnB change whole sectors, challenge shared responsibilities for consumer protection and accessibility, and avoid the impact of regulation and taxation in – for example – urban rental markets. This ‘disavowal’ of ownership and responsibility over collective urban space is effected through the platform metaphor and model, that claims to be a mere information service and that operates on an infrastructural model that is typified as ‘decentralised centralisation’.

Examining new practices of platform security through the lens of the platform economy brings questions of regulation and public values to the fore. If my argument is correct and the platform metaphor and model are now also shaping security practices, the question arises: how does platform security challenge public values? How does it affect existing protections, values, and responsibilities that security actors are committed to and regulated by? If we understand the platform as a metaphor and a mode of power – instead of purely as a business model – then we need to ask how the power of platform security operates and what specific governance challenges it poses.

As I have shown, platform security is typified by ambitions of ‘decentralised centralisation’, where regulatory initiatives and technical systems appear not to be centrally driven, stored, or integrated. This ‘lack’ of centrality poses specific governance challenges. In conclusion, we may say that platform security acts as a practice of obfuscation,Footnote ⁸¹ whereby responsibility over authoritative practices and decisions is (1) discursively disavowed and (2) technically obfuscated. First, this paper has shown several examples of how power is discursively disavowed or minimised by important transnational security institutions. If an institution minimises its role, it refuses to be held accountable in this role. In decentralised centralisation, the ‘hub’ of power appears to be empty. This disavowal does not just deny something but also produces something: it produces a particular arrangement of opacity whereby regulatory change is enacted without accountability or redress. Where can citizens, civil society groups, or other parties anchor objections, questions, and (juridical) responsibility, if the centre of power appears to be empty? This was the case in the ECJ case about AirBnB – with which we started this paper – and it appears also to be the case, for example, in relation to transnational security institutions like FATF. These issue important guidelines and rules concerning the combat against terrorism financing, some of which directly impact national lawmaking, bank’s policies and citizen’s financial inclusion. But they refer any questions about the impact of its work to national government authorities, which, in turn, refer to their obligations under international treaties and cooperation, or to the independent decisions of private sector parties.

Second, in platform security, the operation of power is technically obfuscated. As the empirical examples have shown, the interconnection of decentralised databases implies that there is no central data repository. This is welcomed by civil rights groups and others who are critical of centralised (EU) data storage and the dangers this might entail to privacy. Yet interoperability of databases still makes certain connectivities possible, while entailing a new arrangement of opacity. In a technical model like Mat3ch, for example, the process of matching itself is technical and anonimised. Mat3ch operates on the production of suspicion: only if an anonimised query is matched by a hit in the partner database, can the records be shared. A shareable record, then, is one that is inherently suspect because it appears in more than one database or investigation. Yet this production of suspicion in the fact of a match is not accountable, and not even visible, to the suspect subject themselves. Because privacy rights and responsibilities remain delegated to the owner of the database (the national police authority or private company), the subject’s exercise of rights remains oriented toward the individual (and decentalised) database or data owner. As such, the process of matching itself, and the inferences drawn through these technical practices, remain invisible.Footnote ⁸² Usually, a match can result in a follow-up action via a police authority or a private company (e.g., an investigation or an account closure). However, for the persons affected, it is not at all evident how such security action is initiated or how it could be contested. How could responsibility be anchored not in the database itself, but in the production of connectivities and suspicions? How can the lateral relations between interoperable databases be governed and rendered accountable?

In platform security, decisions and actions remain dispersed and decentralised. It identifies datasets, renders them interoperable, and generates leads. Those leads and analyses, in turn, are rerouted to national security officials and local police so that security interventions can remain national and local. However, the provenance and analytical practices of such leads often remains unknown to those who use them in the national context, as well as to those affected by the actions. It raises questions concerning rights and responsibilities – who is responsible when decisions to remove content or close accounts are wrongly targeted?

In this paper, I have shown a deep analogy between the imaginaries and infrastructures of platform economy and platform security. Like the platform economy, the EU’s self-described ‘information hubs’ seek to connect, collate, and mediate, while minimising their own role. The paper has analysed parallels between the imaginaries and infrastructures of platform economy and the contemporary security practices of organisations like FATF and Europol, to show how practices of decentralised centralisation are crucial to both. Platform security seeks to mobilise and connect local participants, but disclaims responsibility for the content of connectivity. The ‘beautiful report’ produced by a law enforcement analyst, the technical legal support offered by FATF, the suspect match enabled through Mat3ch, are forms of connectivity that are rendered technical and depoliticised. They potentially have great impact on security interventions, but avoid accountability through their decentred nature. Unpacking the parallels between platform economy and platform security fosters a much-needed dialogue between media studies and critical security studies, and helps raise critical questions about the latter, and help devise new ways to anchor accountability in the connection, the match and the report.
