Patent ID: 8824684

Claim:
A computer-implemented method of selectively obfuscating information in a multi-party voice communication, comprising using a processor of a computer for: receiving a signal, during an ongoing multi-party voice communication, from a device with which a selected one of a plurality of participants is participating in the multi-party voice communication, the signal indicating that a next utterance from the selected participant is to be transmitted as an obfuscated segment in the ongoing multi-party voice communication; and responding to the signal, during the ongoing multi-party voice communication, comprising: determining, from among the plurality of participants, a subset of the participants selected to perceive the obfuscated segment; using a participant-specific encryption key, for each of the subset of participants, to encrypt a group-specific decryption key; creating, from the encrypted group-specific decryption key for each of the subset of participants, a descriptor structure in which the encrypted group-specific decryption key for each of the participants in the subset is identified with a corresponding identifier of the participant; obfuscating the next utterance as an obfuscated segment by encrypting the next utterance using a group-specific encryption key that corresponds to the group-specific decryption key; and transmitting the obfuscated segment, and the descriptor structure, to each of the plurality of participants in the multi-party voice communication, thereby enabling each of the participants in the subset to decrypt and perceive the obfuscated segment while preventing remaining ones of the participants of the multi-party voice communication from decrypting and perceiving the obfuscated segment.
