Ensuring the safety of digital image information is a difficult and hotspot in the domain of information processing nowadays.Chaotic sequence can be produced easily and sensitive in the original conditions and parameters.In recent years,it is widely used in image encryption.In this paper,a new image encryption method is proposed.It uses the encryption process to change color values of each image point based on logistic chaotic mapping.Then it scrambles the encrypted image with orthogonal Latin square.The results of experiments shows that this encrypting method is a large space of keys and cann’t be decrypted easily.The encryption effect is satisfactory.
