Abstract: This paper proposes a method for protecting the copyright of MEPG video which bases on the encryption algorithm in the image frequency domain and digital watermarking. This method only encrypts some parts of the video data and injects some important information in the video data which enables identification and tracing of copyright of distributed data.
