Abstract — The image cryptography and steganography performed in frequency domain using random phase mask encodingare presented. These of random phase maskallowsto deccorrelate initial image and makes it unrecognized. This property is used for proposed image encryption and for steganography to increase the security level of the encoded image and to make it less visible. Finally, two keys are needed o decrypt the image. The efficiency of the proposed approach is demonstrated by the computer modeling
