Traditional zero-watermarking algorithm requires characteristic image watermark data. Using these methods

it is often necessary to construct meaningless watermarks. Based on the existing visual cryptography robust watermarking algorithm

combined with zero-watermarking

we present a new visual cryptography zero wavelet domain zero watermarking algorithm. We need to embed the meaningful binary image into the original image

without changing the original image. A zero watermark is not only generated by the carrier image but it is co-produced with the visual watermark secret shares. The proposed algorithm generates two parts:one is the main map component(image feature information) and the other is the ownership chart parts(zero watermark). First of all

using the rational scrambling on the carrier image

it removes the pixel correlation. Second

doing the wavelet transform

the wavelet sub-bands are blocked and the singular value decomposition with each of the blocks is produced.After those steps

we compare each block's characteristic value and the mean value of each block. As a result of that

we can get the transition matrix. Third

the transition matrix is combined with a 2×2 visual secret sharing algorithm to generate the main sharing. Finally

by combining the main sharing with the secret watermarking information

we produce the proprietary sharing and save it to the certification center. Aiming at zero-watermarking information is not very intuitive

in the conditions of not making any changes to the carrier image

we could embed the meaningful binary image into the carrier image. Even in highly robust disturbance environment

this method also has a better performance than the traditional zero-watermarking algorithm. The presented zero-watermarking algorithm of image copyright authentication is a very reliable way to achieve our goals. As shown by our experiment

this algorithm has a good security. In addition to this aspect

it is also more robust when confronted with many different types of image processing.
