UnlimitID
Privacy-Preserving Federated Identity Management using Algebraic MACs
UnlimitID is a method for enhancing the privacy of commodity OAuth and applications such as OpenID Connect, using anonymous attribute-based credentials based on algebrai Message Authentication Codes (aMACs). OAuth is one of the most widely used protocols on the Web, but it exposes each of the requests of a user for data by each relying party (RP) to the identity provider (IdP). Our approach allows for the creation of multiple persistent and unlinkable pseudo- identities and requires no change in the deployed code of relying parties, only in identity providers and the client.
