ABSTRACT
Steganography is a technique to hide information in any digital media such as image, audio, video, or text and allow only the intended user to decode the hidden information. A technique has been developed and explained in this study to embed secret text message using histogram and Discrete Cosine Transformation (DCT) of the cover image. Here, four Least Significant Bits (LSB) of cover image are used to embed secret message. There are several methods of steganography using LSB, but the method proposed here is different in the approach of applying LSB technique and efficiency of the method according to PSNR and BER.
