A steganography technique based on multiple-image interference

Steganography is the science of camouflaging message, video, image or any other data within another file, which can be any multimedia file. The purpose of this technique is to hide the existence of the message in cover file from unauthorized party. It takes the advantages of limited perception of human to observe subtle changes in images, sound etc. Here our concern is about digital images as they are more frequent over the internet. In spy/hacker world Steganography and Cryptography are cousins. Cryptography alters a message so it cannot be understood whereas Steganography hides the message so that it cannot be read. An approach for Steganography Technique Based on multiple-image Interference and position multiplexing is proposed based on the interference principle.
