Abstract
Systems, methods, and computer-readable storage media are provided for enabling discovery of a user by a member of an inner circle of the member when the user is in close proximity to the member. An indication is received from a user device indicating members of an inner circle of the user. A private key is sent to the mobile devices of each member of the inner circle. When the user device broadcasts an encrypted identifier, member devices with the private key can decrypt the encrypted identifier, allowing the member to discover that the user is in close proximity. The user can also update membership of the inner circle so that only members presently in the inner circle can discover that the user is in close proximity.
