A secure and robust video watermarking based on chaotic maps

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 arrive at a like-noise signal. This approach makes extraction of the watermark signal for potential attacker very hard. Embedding locations are selected based on certain principles. The experimental results demonstrate that our proposed watermarking method is highly superior to other techniques and readily achieves the desired robustness and security level.
