Multiple Image Information Hiding Technique Based on Chaotic Sequences

A new information hiding technique in a still image is discussed in this paper. This technique is based on chaotic sequence in the transform domain of covert image. Multiple sensitive images are added to the same covert image as a form of minor noise. The results of theoretical analysis and computer simulation show the new hiding technique has better properties with high security, imperceptibility and capacity for hidden information in comparison with LSB. The image steganography can meet an increasing demand for effective and cheap digital security scheme for the Internet.
