Abstract

Because of the sensitivity of traditional hash algorithms to original data, it is not suitable for image content authentication. In this paper, we analyze and compare image hashing algorithms, realized a difference-value hashing algorithm (dHash), and apply the dHash algorithm to a blockchain-based image copyright protection system. dHash algorithm determines the similarity of images to ensure the uniqueness of image copyright.The test shows that the dHash algorithm has high accuracy and faster speed of images with Gaussian noise.
