Abstract :
Invariant moments technology is an important research area and has been widely used in the area of image processing and analysis. This paper described the theory of invariant moments, especially the properties of the Legendre invariant moments. On this basis, the encryption algorithm based on Legendre invariant moments was proposed. This algorithm has good resistance to geometric attacks. Experimental results show the validity of the algorithm.
