概要
- 論文の詳細を見る
A novel public watermarking algorithm based on chaotic properties is proposed. Thanks to good randomness and easy reproducibility of chaos, firstly the watermark is permuted by chaotic sequences, then a small number of reference points are selected randomly in the middle frequency bands of DCT domain, and the variable number disorder watermark bits are embedded into the neighborhood of each reference point according to chaotic sequences. The experimental results show the invisibility and robustness.
