%X To obtain more robust and secure image hash value, this paper proposed a novel image hashing scheme based on human visual system in the ridgelet transform. Firstly it preprocessed the original image, then extracted coefficients after ridgelet transform based on human visual system , finally quantified and compressed them to generate the final hash value. The experimental results demonstrate that the scheme has a good performance against JPEG compression, filtering, adding noise, cropping and rotation. It can also distinguish malicious tampering. The hash has good robustness and security.
