  • Privacy ensured brokered identity federation
    Patent number: 11082418
    Abstract: A system, method, apparatus, and computer program product for a privacy ensured brokered identity federation system. The privacy ensured brokered identity federation system connects a user in a brokered identity federation environment that blinds relying parties (RP) from credential service providers (CSP), blinds CSPs from RPs, and blinds a user's identity and data from the federation middleware hubs. The system utilizes ring signatures to attest to CSPs that a valid RP of the federation is making a request. The process utilizes CSP ring signatures to assure RPs that a valid CSP of the federation has provided a response. The process utilizes per transaction encryption keys created by the RP to ensure the federation has no access to data messages. It can further ensure that only the correct RP can decrypt a CSP response.
