Data Cooperatives for Identity Attestations
CoRR(2023)
摘要
Data cooperatives with fiduciary obligations to members provide a useful
source of truthful information regarding a given member whose personal data is
managed by the cooperative. Since one of the main propositions the cooperative
model is to protect the data privacy of members, we explore the notion of
blinded attestations in which the identity of the subject is removed from the
attestations issued by the cooperative regarding one of its members. This is
performed at the request of the individual member. We propose the use of a
legal entity to countersign the blinded attestation, one that has an
attorney-client relationship with the cooperative, and which can henceforth
become the legal point of contact for inquiries regarding the individual
related to the attribute being attested. There are several use-cases for this
feature, including the Funds Travel Rule in transactions in digital assets, and
the protection of privacy in decentralized social networks.
