Consent Receipts for a Usable and Auditable Web of Personal Data

Abstract

Consenting on the Web, in the context of online privacy and data protection, is universally accepted as a difficult problem, mainly because of its cross-disciplinarity. For example, any approach to online Consenting needs to meet usability, legal, regulatory, technical, and business requirements. To date, effort has been predominantly focused on meeting compliance with regulations and automation, and less on the true re-empowerment of users with respect to their personal data. One approach that has not seen sufficient research is the use of 'Consent Receipts', which offer a new paradigm of recording interactions concerning consent and using them as proofs in future actions, similar to familiar use of a common shopping receipt. In addition to being a record, receipts encourage accountability in how technology handles consent and is beneficial for all involved stakeholders. For organisations, it assists with legal requirements for demonstration of valid consent, while for users it provides transparency and accountability by being a proof to be used against malpractices related to consent. Receipts also have uses in addition to those related to consent, such as for authorising the holder in exercising related rights. This paper analyses the requirements, uses, and benefits offered by Consent Receipts with an extensive and broad literature review. Since receipts are a novel concept, we identify properties and requirements, and then new mechanisms necessary for the Web to support receipts. We then demonstrate feasibility of receipts through proof-of-concepts in three common real-world use-cases: (a) acceptance of a privacy policy and its subsequent changes; (b) choices expressed via consent dialogues or cookie banners; and (c) verbal interactions with Amazon Alexa.

Data Protection and Consenting Communication Mechanisms: Current Open Proposals and Challenges

“…Note that a simple threat to any consent model is that a data controller can claim plausible deniability by claiming that either the signal was not received or that an external process manufactured it outside of the user's direct control. While it adds algorithmic complexity, accountability can be achieved at no cost to the user experience [25]. DPCCMs that only generate binary signals do not, on their own, meet sufficient accountability requirements.…”

“…The second approach, which is sponsored by CCPAs, is to use simple notifications, or "signals" such as the Global Privacy Control (GPC), sent directly from the user agent (often a browser) and, commonly, which can be asynchronously to a notice (see a comprehensive overview on consent signals in [31]). The third approach is to rely on an authenticated user artefact, such as a Consent Receipt [1], that enables management of the consent lifecycle thus removing the focus from the point of collection and bringing to the front accountability and transparency.…”
