ABSTRACT:
A method and system for securely and scalably encoding data are disclosed. A method and system for decoding data which has been securely and scalably encoding are also disclosed. In one encoding method embodiment, the present invention recites receiving data. The present method then segments the data into corresponding regions. The regions are then scalably encoded into scalable data. The present embodiment then progressively encrypts the scalable data to generate progressively encrypted scalable data. Next, the present embodiment packetizes the progressively encrypted scalable data.
