Image Hash Authentication Scheme Based on Composite Domain

A new image hash scheme is proposed in this study, which depends on the characteristics of robust Harris corner points and DCT-DWT composite domain. The contributions are as follows: 1) the hash is robust against image tampering and malicious attacks 2) the signature extracted by this scheme helps conserve storage space. Experimental results indicate that the scheme is more robust against JPEG lossy compression, channel additive noise, brightness changes, filtering and a large class of attacks, including image tampering or large geometric transforms (e.g. rotation, extrusion, and cutting) than current single-domain extracting schemes, which results in an improved level of image security and robustness.
