  Abstract

In this paper, distribution of digital contents over the Information network makes it possible for users to have joint ownership and it make illegal copy and forgery of digital contents. We propose a digital image encryption method using DC and DPCM coefficient on DCT based to encryption methods which use MIPEG(Motion JPEG), JPEG2000 and MPEG1,2,4, in DVR(Digital Video Recoder). We encrypted image by the DCT processed 8×8 blocks of contents authorship. Experimental results show that proposed method can be used to digital image data encryption. Also the proposed algorithm is reduced blocks number on DCT and implemented high speed memory as encryption to video images.
