<P>PROBLEM TO BE SOLVED: To exchange data messages among two or more communication devices without any other communication device being able to analyze, access or understand the data messages. <P>SOLUTION: An inviter communication device generates an inviter public/private key pair. A request to establish a communication session with an invitee communication device which includes the inviter public key and an invitee identifier and is to be sent to the invitee communication device via a server is sent. A bucket uniform resource identifier (URI) identifying a location for storing data messages exchanged during the communication session and an invitee public key are received from the server upon acceptance of the request by the invitee communication device. A data message for the invitee communication device is encrypted with the invitee public key. The encrypted data message is sent to the bucket uniform resource identifier for retrieval by the invitee communication device. <P>COPYRIGHT: (C)2012,JPO&INPIT |
