    Adapting the TPL Trust Policy Language for a Self-Sovereign Identity World
    (Open Identity Summit 2021, 2021) Alber, Lukas; More, Stefan; Mödersheim, Sebastian; Schlichtkrull, Anders
    Trust policies enable the automated processing of trust decisions for electronic transactions. We consider the Trust Policy Language TPL of the LIGHTest project [Mö19] that was designed for businesses and organizations to formulate their trust policies. Using TPL, organizations can decide if and how they want to rely on existing trust schemes like Europe’s eIDAS or trust scheme translations endorsed by them. While the LIGHTest project is geared towards classical approaches like PKI-based trust infrastructures and X.509 certificates, novel concepts are on the rise: one example is the self-sovereign identity (SSI) model that enables users better control of their credentials, offers more privacy, and supports decentralized solutions. Since SSI is based on distributed ledger (DL) technology, it is a question of how TPL can be adapted so that organizations can continue to enjoy the benefits of flexible policy descriptions with automated evaluation at a very high level of reliability. Our contribution is a first step towards integrating SSI and the interaction with a DL into a Trust Policy Language. We discuss this on a more conceptual level and also show required TPL modifications. We demonstrate that we can integrate SSI concepts into TPL without changing the syntax and semantics of TPL itself and have to add new formats and introduce a new built-in predicate for interacting with the DL. Another advantage of this is that the “business logic” aspect of a policy does not need to change, enable re-use of existing policies with the new trust model.

    Role of Identity, Identification, and Receipts for Consent
    (Open Identity Summit 2021, 2021) J. Pandit, Harshvardhan; Jesus, Vitor; Ammai, Shankar; Lizar, Mark; D’Agostino, Salvatore
    This article outlines issues in the current ecosystem of data sharing based on consent and the role of identity and identification. It argues how the consent mechanism is hostile to individuals in the form of: (a) inscrutable third parties who remain largely unknown; (b) denying ability to identify and manage consent; and (c) lack of technological solution. The article discusses the role and feasibility of Consent Receipts, and presents its role in the Privacy as Expected: Consent Gateway (PaE:CG) project for the future of accountable identity and identification mechanisms for consent.
