Abstract

A new method for digital video watermarking is presented in this paper. For data embedding we use 3-D ridgelet domain introduced by Helbert. The redundancy of this transform is substantial, so extraction of the hidden data is impossible in this domain. To overcome this problem, we introduce a modified ridgelet transform with little redundancy, and embed watermark in this domain. Experimental results show that this scheme is robust against collusion attack, frame cropping, frame swapping, frame dropping, noise attack and the MJPEG (Motion JPEG) compression.
