Steganography is one of the most powerful techniques to conceal the existence of hidden secret message inside a cover medium like image, video, audio, etc.An image is a suitable cover object for steganography because of its great amount of redundant spaces and its abundance.This paper represents a secure steganography scheme which incorporating discrete wavelet transform (DWT) and the stability of the singular values with logistic map-based encryption.In this proposed scheme first of all, the secret image has been encrypted using the logistic map.The encrypted image is added to singular value of original image after two-level DWT to form the stego-image.In this paper the Peak Signal to Noise Ratio (PSNR), correlation coefficient (CR) are used to evaluate the transparency and security of algorithm.
