Double images hiding based on optical interference
نویسندگان
چکیده
A double images hiding technology based on optical interference is proposed. The images are hiding into two computer generated phase only masks which are located at the determined positions. Two beams propagate through the masks and interfere at the preset positions. The desired images will appear at the preset positions. The positions coordinates and wavelength can also be used as encoding parameters. Computer simulations show the validity of this new method. 2009 Elsevier B.V. All rights reserved.

Improving security of double random phase encoding with chaos theory using fractal images
This study presents a new method based on the combination of cryptography and information hiding methods. Firstly, the image is encoded by the Double Random Phase Encoding (DRPE) technique. The real and imaginary parts of the encoded image are subsequently embedded into an enlarged normalized host image. DRPE demands two random phase mask keys to decode the decrypted image at the destination. T...
