Abstract

Steganography is an important area of research in recent years involving a number of applications. It is the science of embedding information into the cover image without causing statistically significant modification to the cover image. In this paper we propose an image Steganography that can verify the reliability of the information being transmitted to the receiver. This paper is based on the comparison of the DCT and DWT method. DCT and DWT algorithm are implemented in frequency domain in which the cover image is transformed from spatial domain to the frequency domain and the secret image is embedded into the frequency components of the cover image. The performance and comparison of these two techniques is evaluated on the basis of the parameters MSE, PSNR, processing time and capacity
