For the low robustness characteristics of LSB digital watermarking model, presents a digital watermarking method based on hybrid optical bistable model to improve the robust of LSB. The algorithm uses Hamming code to encode for the need of embedded watermark, and then encrypts Arnold scrambling and mixed bistable model watermark, after four random image watermark embedding, so the watermark robust has been well improved. Simulation results show that the algorithm for noise superimposed, cropping and other attacks has better security.
