This paper considers the use of selective encryption systems for compressed video data that can support transcoding of the encrypted bit-streams without the need for decryption and re-encryption. The focus is on the use of the H.264 video codec. However, the concepts can be easily extended to any video coding standard. I-frame encryption encrypts only the intra frames, making it suitable for use with modified interframe transcoders that operate only on P and B frames. These interframe… CONTINUE READING
