Abstract
This paper puts forward a kind of robust watermarking algorithm based on block SVD, the hybrid system and balanced multiwavelet. To being embedded watermarking signal, it should make hybrid chaotic system to be scrambled and encrypted. Then the coverimage should be changed by cardbal2 multiwavelet. Low frequency sub-band is done 4 × 4 blocks, SVD handling and embedded according to embedded coefficients and equilibrium factor. The experimental results show that this algorithm has good invisibility and robustness.关键词
