Palette-Based Image Steganography by Mapping Pixels to Letters

Abstract

This paper is represented for information security by using image steganography method on palette-based image. The palette image based steganography is used LSB encoding procedure. Steganograpyh is the art of hiding information in other information media when communication is take place. Many different file formats can be use, but digital images are more popular usages. We propose the encoding the message to an image and the decoding this message by mapping pixels to letters. The result image is not different as in original image. So, the intruders can’t know the messages embedded in the image until they get that image.
