ABSTRACT

                Steganography is a technique to hide secret messages into the media cover so that their existence cannot be detected by unauthorized parties. In the digital era, steganography can be carried out on various digital media with bits that can be engineered. In this research, steganography will be carried out on digital image files that are used as cover image files or decoration images for MP3 version 2 and above (ID3v2 Tag).  The steganography method used in this research is modifying the LSB (least significant bit) of the RGB (Red, Green, and Blue) value of digital images to hide the bits of the digital messages so it does not interfere with the quality of the image that used as a cover. From the research, it can be concluded that steganography on MP3 cover image files can be carried out well on BMP and PNG images, where the quality of the cover image does not experience a significant decrease. The secret messages can be hidden in the cover image, without disturbing or decreasing the quality of audio from the MP3 files because only the cover image was modified.
