Abstract
ABSTRACT Data security and confidentiality is an important aspect of information. The importance of the value of information in every aspect can make it possible to transfer information or data theft by unauthorized parties. One technique for securing data and information is to apply the use of steganography techniques. This study compares the two methods of steganography namely Pixel Value Differencing (PVD) and Modulus Function (MF) to find out which method is better in terms of image quality and message storage capacity. This research was developed using the Python programming language with the images tested in both methods are PNG format images. Based on the results of tests conducted by the PVD algorithm produces better image quality than the MF algorithm because it produces Peak Signal to Noise Ratio (PSNR) values with an average of more than 40dB and the PVD algorithm also produces a stego image that can accommodate more messages than the MF algorithm .
