Abstract

A method (400) and system for communicating in a group of communication devices is disclosed. The method at a first communication device (104) includes receiving (404) a first trust level change request from a second communication device (108). The first trust level is associated with the first communication device and the second communication device (108). Further, a group trust level is associated with the group of communication devices. Further, the method includes modifying (406) the first trust level based on historical data associated with the first communication device and the second communication device. The historical data is a function of at least one of duration of communication, frequency of the communication, and content of data exchanged, between the first communication device and the second communication device.
