Abstract

Information is a message in the form of a utterance or phrase that can consist of symbols, or meanings that can be interpreted from a message or a collection of messages. Steganography is a technique that can be used to hide information on a media. In the digital era, the media used can be audio, image, or video. In its use, the concealment of messages is done by making small changes to a digital medium so as not to attract the attention of other people or attackers. In general, the concealment of a data or message on the image media is a technique that is often used in the implementation of steganography. In the use of image media, steganography can be implemented with existing methods; in this journal will be implemented Least Significant Bit (LSB) and Spread Spectrum method, which will further determine the analysis of image quality and comparison of both methods.
