Video protection by color watermark using a modified cyclic insertion scheme

Abstract

This paper presents an original algorithm for copyrighting video content by inserting a color watermark. The optimal parameters of the algorithm allow lossless watermark extraction from H.264 encoded video are determined. The proposed algorithm is based on YCbCr transformation, block SVD decomposition, bitplane decomposition and modified reduced cyclic insertion scheme. The results obtained confirm the effectiveness of the proposed algorithm and it can be successfully applied in the protection of video content by color watermark without visible degradation of video content.
