A Steganography Approach to hiding two images using DNA microarray

Suman Chakraborty, Prof. Samir Kumar Bandyopadhyay

The steganography is defined as to hide information from unauthorized user. Degree of success of a staganography procedure depends on two factors –First, amount of information hiding,second,rate of distortion of cover image.In this paper propose a unique method of steganography which hidings two secret images with in a cover image. Uniqueness of this method is that hide two secret images without distortion of cover image.DNA microarray and it’s hybridization procedure use as a tool for implementation.
