A chaos-based video watermarking algorithm

Abstract

The intriguing characteristics of chaotic maps have prompted researchers to use these sequences in watermarking systems to good effect. In this paper we aim to use a tent map to encrypt the binary logo to achieve a like-noise signal. This approach makes extraction of the watermark signal by potential attacker very hard. Embedding locations are selected based on certain principles. Experimental results demonstrate that our proposed watermarking method is highly superior to other techniques reported in literature and readily achieves the desired robustness and security level.
