Recently, several scrambling techniques have been proposed for video digitally archived. These methods realize efficient processing by partial encryption on MPEG compressed data while keeping compatibility toMPEG format. However, they have common drawbacks expanding the entire code. Also, they have not reported on local shuffling in a frame. In this work, we propose a new video scrambling scheme on MPEG compressed domain, which shuffles a part of DC and AC coeffecients by DCT in a frame. Our scheme is applicable to local region without data expansion from the original MPEG file.
