This paper presents two algorithms for detection of plain copy-move regions—fully matching fragments—in images. Both algorithms represent data of the fragment in the form of a hash value, where the hash function is constructed using different mathematical principles: probability-theoretical and numerical-theoretical. The paper presents a comparison of the proposed algorithms, as well as recommendations for their use.
