Perancangan Aplikasi Steganografi Menggunakan Metode Adaptive Minimum Error Least Significant Bit Replacement

Abstract

Steganography is a method to allow users to hide a message in another message in the form of digital media, the message to be conveyed is hidden in a digital media so that it is hoped that it will not cause suspicion from other parties who do not want to know the secret message the. There are two general stages in digital steganography, namely the process of embedding or encoding (insertion) and the process of extracting or decoding (revealing or revealing). The results obtained after the embedding or encoding process are called stego objects (if the storage media is only in the form of image data, it is called Stego Image). AMELSBR insertion method, the process is not the same as the LSB method. If the insertion process in the LSB method is done directly per pixel in its bytes, where the last 1 bit (LSB) per byte is replaced by 1 secret data bit to be inserted, but not by the AMELSBR method. In this method, the cover image will be divided into several blocks first. Each block will be 3 x 3 pixels or 9 pixels.
