Abstract: The use of digital media as a means of information exchange is common in the present. There is certain information that can be called confidential information. Indicated by a person or a particular party to another party. In order to avoid any information leakage required a special technique in the delivery of this confidential information. Steganography is a technique that can protect this secret information. The meaning of steganography in Greek is the concealment of a writing or data. Secret messages can be hidden in media form such as text, image, audio and video. In use on imagery there is a method called Least Significant Bit (LSB). LSB is the basic method used. This method replaces the value of pixels in a digital image with secret data using ASCII value. Changes in the color of the image are not visible to the eye due to the replacement of small pixel values. In this study, we will discuss the use of steganography on JPEG image with LSB method. To determine whether messages can be well hidden and stego images still have good quality.
