Implicit population of access control lists

Abstract:

Communication applications may include lists of users with which a user of the application communicates. If two users of a communications application each include the other user on their user lists, an implicit trust may be established between the users. For example, if user A includes user B in her list and user B includes user A in his list, then it may be determined that each user knows and/or trusts the other user. As a result, a connection or communications pathway may be automatically created between the client devices of the users to facilitate communications between the users based on the implicit trust.
