Digital Image Security Application With Arnold Cat Map (ACM)

Abstract

The development of science and technology is advancing. Therefore, the data security needs to be applied. Cryptography is one of the sciences that learn mathematical techniques related to aspects of information security such as secrecy. One of them is known as Arnold Cat Map (ACM) algorithm on encryption and decryption by iterating digital images to secure an image. Arnold Cat Map (ACM) algorithm is one of the common cryptographic algorithms used to encrypt images. Application designed to secure an image by performing the process of randomizing the image pixel, the randomized image will change the pixel position based on the Arnold Cat Map method, then encryption and then the image encryption results become unknown. The result of the Arnold Cat Map method is that the random pixel position will return to its original position after going through several iterations with reference to the image capacity, where if the image size is different, the iteration will return to the original with different iteration point at time of encryption or decryption system by Arnold Cat Map method.
