Abstract
A social network (SNET) is divided into one or more circles employing separate security secrets, e.g. keys, for communication between members. A device can be a member of more than one circle, and store different keys for each of those circles in separate, restricted portions of memory. When a member leaves a circle, new keys can be generated and distributed to the remaining members. Before and after joining a circle, a level of trust associated with the device or human member can be determined based on third party trust verification and a trust history. A requirement for multiple current circle members to vouch for the prospective member can be imposed as a condition of membership. Each circle can be assigned different trust and access levels, and authorization to receive information can be checked before transmitting information between circles.
