In this paper, a new asymmetric method is presented to encrypt and compress color images using discrete cosine transform in Fresnel domain. First, the input color image is decomposed into three channels: red, green and blue. Each channel image is con

In this paper, a triple random phase encryption scheme in the Fresnel domain is presented in a 4f system. The scheme is an extension of the double random phase encoding scheme in the Fresnel domain. Firstly, the image is subjected to double random ph

In this digital world, images are an important part of communication and while communicating security is a crucial problem. And to deal with security various image encryption techniques are based on cellular automata. The study gives a basic introduc

In this paper, a novel scheme for the secure transmission of phase images is presented. A phase image is bonded with a random amplitude mask and subjected to the Fresnel transform followed by Lorenz map. Thereafter, a random phase mask is bonded with
