STEGANOGRAPHY IMPLEMENTATION OF INSERTION OF CONFIDENTIAL DATA ON DIGITAL IMAGE MEDIA

Abstract

Sending confidential messages through the internet is very vulnerable to theft, many irresponsible parties try to get information from these messages for personal gain. So that the secret message can only be read and understood by certain parties, a way is needed to hide the message, namely with steganography. Steganography is a technique to hide messages in media such as text, images, audio and video so that the media that is inserted looks like normal. Bit-Plane Complexity Segmentation (BPCS) is a steganographic method used in message embedding. This method has a large message insertion capacity. The insertion is done by replacing the complex bit-pane with a secret message block. In this final project, a software is developed that applies the steganography method with the BPCS method on uncompressed images. In addition, tests were conducted to analyze the suitability of the BPCS method on uncompressed images. The final result obtained is a software capable of handling message insertion. The conclusion of this research is that the BPCS algorithm is proven to be able to solve the problem of inserting messages into image media.
