Abstract
A user device generates a social graph-based user certificate that conveys a trust level to other users of the social network. A user certificate for a user is obtained, the user having a user public key and corresponding user private key. A plurality of potential signers is identified within one or more social networks. The certificate is then sent to the identified plurality of potential signers. One or more signed versions of the user certificate may be received from at least some of the plurality of potential signers. The user device may assign a signer weight to each signed version of the user certificate, each corresponding signer weight associated with the signer of each signed version of the certificate. The user certificate, the user signature, one or more signed versions of the user certificate, and the user-assigned signer weights are distributed to one or more recipients.
