Multilevel Encryption for Classified Multimedia Applications in MPEG-7
In order to address the security issues of the classified multimedia contents,a multilevel encryption scheme is presented which support multilevel encryption by introducing the time seed which used for generating time master key and then further generating encryptian key.This scheme takes advantage of the properties of MPEG-7 standard to generate the multimedia hierarchy organized into tree structure involving many elements each of which belongs to a security clearance level,the sensitive element or security content can be encrypted with proper key in term of security level and then the entire multimedia encrypted with another appropriate key and the multilevel encryption achieved.
