Abstract
A sending device exchanges handshake signals with a receiving device prior to the delivery of compressed digital audio data. The sending and receiving devices are remotely connected using a data network. In one embodiment of the present invention, the sending device sends an access code to the receiving device. The access code is an encrypted data of two components: a digital data associated with the sending device and a digital data associated with the receiving device. The receiving device decrypts the access code. The receiving device stores the compressed digital audio data in its memory if the decrypted access code contains the correct components.
