Abstract

In this paper, a novel visual cryptography (VC) copyright protection scheme based on artificial bee colony algorithm (ABCA) is proposed. First, we apply wavelet decomposition (discrete wavelet transform, DWT) to decompose the cover image, and ABCA is used to adaptively select feature sub-blocks. Then singular value decomposition (SVD) is implemented to extract the image feature, which is classified into two clusters for generating the master share. Finally, ownership share is generated with the help of the secret image and the master share. In the process of ownership identification, the secret image can be acquired by stacking the master share and the ownership share. Experimental results show that the proposed scheme is robust and effectively resists several different signal processing attacks, without any distortion of the cover image.
