Image Based Steganography Using Modified LSB Insertion Method with Contrast Stretching

Abstract

The main objective of this research paper is to suggest a new steganography method based on a LSB insertion method and contrast stretching image histogram modification. The stego-images, obtained using the proposed data hiding method, are robust to RS steganalysis. The application of proposed method has comparatively higher secret data embedding capacity than classical LSB insertion method. The experimental results shows that the RS steganalysis fails to detect the presence of the secret message even its length is 50% of the maximum possible embedding length in the cover image.
