Abstract:
In a method for securely distributing data in group communication, the group has a plurality of members, and the method includes the following steps: (A) under a data recording mode, assigning one member of the group as a recording member; (B) enabling the recording member to generate and send a security key to other members of the group, to record communication contents of all the members during a group communication session, and to create an entry of recorded data therefor; and (C) enabling the other members of the group to receive and store the security key, the security key enabling the other members of the group to retrieve the recorded data from the recording member under a data retrieval mode.
