Abstract
Embodiments of a decentralized, distributed trust mechanism that may be used in peer-to-peer platforms, to implement trust relationships based on data relevance between peers on a network and to implement trust relationships between peers and content and data (codat). In one embodiment, the trust mechanism may provide a trust spectrum of multiple levels wherein unique peer identities may be established to enable authentication and the assignment of the peers' associated access policies within a peer group. In one embodiment, the trust spectrum may have Certificate Authority signed certificates as a maximum level of security, and self-signed certificates as a minimum level of security. Since a certificate is one form of codat, in one embodiment the trust mechanism may be applied to a peer group member's collection of signed certificates for a given peer group.
