摘要

Information security is one of the most interested topic in computer science filed, is art of hiding data in cover media like audio, image, etc. In this paper I will focus on two different methods hiding based on least significant bit and discrete cosine transform and compare between the result based on some measurement that calculated MSE, PSNR and SSIM. And based on those factors the result of hiding based on DCT achieve result better than LSB as shown MSE of LSB 16.1722 when hide 3 bits, PSNR of LSB=36.0771 and SSIM of LSB=0.9872 compare with Discrete Cosine transform MSE of DCT =7.981 when hide 3 bits, PSNR of DCT=41.001 and SSIM of DCT=0.901 as shown above the result of hiding based on DCT is better than LSB.
