  We are taught from a young age that plagiarism (copying other's work) is
wrong. However, the problem of Illegal copies of multimedia data is exacerbated
by the widespread availability of circumvention devices, which enable people to
make infringing copies of multimedia data. Recently, Joint Video Compression
and Encryption (JVCE) has gained increased attention to reduce the
computational complexity of video compression, as well as provide encryption of
multimedia data. In this paper, a novel protection method for multimedia data
(ECAKP) is proposed. It combines encryption process and compression with
authenticating process. The method had been implemented and the results are
discussed in detail.
