Secure and robust image hashing scheme
一种安全鲁棒的图像哈希方法*

With the development of Internet,the issue of multimedia copyright protection becomes urgent day and day,making the image hashing for image authentication obtaining extensive research and application.This paper proposed a novel image hashing scheme based on V-system.It first modulated the image pixels to get a intensity-transformed version,then extracted coefficients after V transform to generate the hash value.The experimental results demonstrate that the scheme has a good performance against attacks.
