REPHRAIN: Research centre on Privacy, Harm Reduction and Adversarial Influence online

Lead Research Organisation: University of Bristol
Department Name: Computer Science

Abstract

The REsearch centre on Privacy, Harm Reduction and Adversarial INfluence online (REPHRAIN) will bring together the UK's substantial academic, industry, policy and third sector capabilities to address the current tensions and imbalances between the substantial benefits to be gained by full participation in the digital economy and the potential for harm through loss of privacy, insecurity, disinformation and a myriad of other online harms.

Combining world-leading experts from the Universities of Bristol, Edinburgh, Bath, King's and UCL, the REPHRAIN Centre will use an interdisciplinary approach - alongside principles of responsible innovation and creative engagement - to develop new insights that allow the socio-economic benefits of a digital economy to be maximised whilst minimising the online harms that emerge from this.

REPHRAIN's leadership team will drive these insights in technical, social, behavioural, policy and regulatory research on privacy, privacy enhancing technologies and online harms, through an initial scoping phase and 25 inaugural projects.

The work of REPHRAIN will be focused around three core missions and four engagement and impact objectives. Mission 1 emphasises the requirement to deliver privacy at scale whilst mitigating its misuse to inflict harms. This will focus on reconciling the tension between data privacy and lawful expectations of transparency by not only drawing heavily on advances in privacy-enhancing technologies (PETs), but also leveraging the full range of socio-technical approaches to rethink how we can best address potential trade-offs. Mission 2 emphasises the need to minimise harms whilst maximising the benefits from a sharing-driven digital economy, redressing citizens' rights in transactions in the data-driven economic model by transforming the narrative from privacy as confidentiality only to also include agency, control, transparency and ethical and social values. Finally, Mission 3 focuses on addressing the balance between individual agency and social good, developing a rigorous understanding of what privacy represents for different sectors and groups in society (including those hard to reach), the different online harms to which they may be exposed, and the cultural and societal nuances impacting effectiveness of harm-reduction approaches in practice.

These missions are supported by four engagement and impact objectives that represent core pillars of REPHRAIN's approach: (1) design and engagement; (2) adoption and adoptability; (3) responsible, inclusive and ethical innovation; and (4) policy and regulation. Combined, these objectives will deliver co-production, co-creation and impact at scale across academia, industry, policy and the third sector.

These activities will be complemented by a capability fund, which will ensure that REPHRAIN activities remain flexible and responsive to current issues, addressing emerging capability gaps, maximising impact and cultivating a public space for collaboration. REPHRAIN will be managed by a Strategic Board and supported by an External Advisory Group, the REPHRAIN Ethics Board, and will work with multiple external stakeholders across industry, public, and the third sector.

Outcomes from the centre will be synthesised into the REPHRAIN Toolbox - a one-stop resource for researchers, practitioners, policy-makers, regulators and citizens - which will contribute to developing a culture of continuous learning, collaboration and open engagement and reflection within the area of online harm reduction.

Overall, REPHRAIN focuses on interdisciplinary leadership provided by a highly experienced team and supported by state-of-the-art facilities, to develop and apply scientific expertise to ensure that the benefits of a digital society can be enjoyed safely and securely by all.

Results and Impact Digital participation is critical to our shared access to many essential services, such as education and healthcare. This participation is managed and realised, in part, through avenues such as the Internet, which is rapidly being recognised as a public utility, in a similar manner to transport, infrastructure, etc. While the safety and standards of roads, for example, are long established as matters for public discourse, the debate around online safety is now beginning to gain a similar traction.

One example of this growing concern is the establishment and observation of a Safer Internet Day globally - this blog will summarise and reflect on the efforts previously made by system designers, policy makers, local authorities, schools, and parents, using our own expertise and experience to highlight and evolve useful insights for the future.

Results and Impact This blog will highlight how educational privacy games offer a fun and interactive way of engaging with issues of online privacy. While traditional privacy education strives to convey information in static form, games allow users to become part of the action. By making decisions within the game's virtual world (such as with whom to share personal data), the user can simulate the impact of their actions, which can be highly useful for the user's understanding of real-world phenomena like how decisions about what data you share can impact yourself and others.

There are many ways of implementing educational privacy games and this blog post explores four such games with different gameplay styles and approaches to teaching players about privacy. Firstly looking at games with simpler mechanics, and how such mechanics constrain their effectiveness in teaching online privacy. Then to examine more complex mechanics and discuss why they can better convey how to think about online privacy. However, for any educational privacy game to be effective, it must also be available to the public, and so the analysis concludes with argument for developing the capabilities of universities to develop and maintain games.

Results and Impact Commercialization of consumers' personal data in the digital economy poses serious, both conceptual and practical, challenges to the traditional approach of Consumer Law. This talk argues that mass-spread, automated, algorithmic decision-making casts doubt on the foundational paradigm of consumer law: consent and autonomy. Moreover, it poses threats of discrimination and undermining of consumer privacy. It is argued that the recent legislative reaction by the EU Commission, in the form of the 'New Deal for Consumers', was a step in the right direction, but fell short due to its continued reliance on consent, autonomy and failure to adequately protect consumers from indirect discrimination. It is posited that a focus on creating a contracting landscape where the consumer may be properly informed in material respects is required, which in turn necessitates blending the approaches of competition, consumer protection and data protection laws.

Results and Impact Fair exchange protocols let two mutually distrusted parties exchange digital data in a way that neither can cheat. At CCS 2017, Campanelli et al. proposed two blockchain-based protocols for the fair exchange of digital coins and a certain service, i.e., "proofs of retrievability" (PoR), that take place between a buyer and seller. Using fair exchange protocols, users can avoid falling to victim of (certain) frauds. This talk will explain that Campanelli's schemes have two serious issues that we identified; namely, (1) a malicious client can waste the seller's resources, and (2) real-time leakage of information to non-participants in the exchange. It will also explain how we can rectify the issues by using our proposed scheme, called "recurring contingent PoR payment" (RC-PoR-P). It lets the fair exchange reoccur while ensuring that the seller's resources are not wasted, and the parties' privacy is preserved. We have implemented the RCPoR-P. Our cost analysis indicates that the RC-PoR-P is efficient. The RC-PoR-P is the first of its kind that offers all the above features.

Form Of Engagement Activity A talk or presentation

Geographic Reach National
Primary Audience Other audiences
Results and Impact Private Set Intersection protocols (PSIs) allow parties to compute the intersection of their private sets, such that nothing about the sets elements beyond the intersection is revealed. PSIs have a variety of applications, primarily in efficiently supporting data sharing in a privacy-preserving manner (e.g., in financial institutes, e-commerce, or even COVID 19 contact tracing solutions). At Eurocrypt 2019, Ghosh and Nilges proposed three efficient PSIs based on the polynomial representation of sets and proved their security against active adversaries. This talk explained that these three PSIs are susceptible to several serious attacks. The attacks let an adversary (1) learn the correct intersection while making its victim believe that the intersection is empty, (2) learn a certain element of its victim s set beyond the intersection, and (3) delete multiple elements of its victim s input set. I will explain why the proofs did not identify these attacks and describe how the attacks can be mitigated.

Results and Impact The core REPHRAIN research team ran a series of 11 workshops focused on types of online harm, existing approaches around addressing such harms, and other areas of harm that have not yet been addressed. The challenges around investigating certain online harms were also discussed and how best they can be addressed. The workshops were designed to address specific audiences at each event: academics (41); policymakers/regulatory bodies (35); industry (17); law enforcement/third sector organisations (9) and safety tech providers. The aim of the workshops was to elicit comment and input from the specific groups to provide insight for the formulation of the REPHRAIN scoping document alongside a literary review. The scoping document was then utilised to inform the first REPHRAIN strategic funding call and also the UKRO Protecting Citizens Online call for complementary projects.
