Abstract

Least Significant Bit (LSB) is one method used in steganography to store messages in an image. In the LSB method there is still a gap to corrupt the message in the stego image if it is modified. As the result, the message in the stego image is corrupted. In this study, the modification process of the LSB method will be carried out by inserting the Redundant Pattern Encoding (RPE) method. The Redundant Pattern Encoding method will divide the stego image into patch A and patch B, then the message will be inserted into each patch. The results of the modification process on the Least Significant Bit method with Redundant Pattern Encoding, that is, the messages on the stego image can survive if the Segmentation is increased by a rate of 10% to 50%, Image Compression with a rate of 5% to 15% and Image Enhancement with a rate of 5% to 25 %. The message on the stego image cannot survive if they experience by giving of Color Image Processing and Noise thoroughly on both patches
