Encryption and Decryption Digital Holograph With 2-Dimensional Arnold Affine Module Transformation
Dongmei Wang · 2004
In the paper a formula of Arnold affine module transformation for image is presented, the periodicity of that is the same as the one of image's; The disadvantages of Arnold affine module transformed images are analyzed. To enhance the security of the Arnold affine module transformation, a hybrid method which transforms digital holograms generated by virtual optics is proposed.
