The exchange of information, still vulnerable amid technological advancements, prompts software developers to enhance digital security strategies. This research conducts experiments by combining three layers of security—Vigenere encryption, Least Significant Bit (LSB) method, and Linear Congruential Generator (LCG) method—as a solution to improve digital security. To assess the accuracy of the security model, the generated images are measured using Peak Signal-to-Noise Ratio (PSNR) calculations. Information is encrypted using Vigenere encryption, which encrypts each plaintext character in the input data with a different key. The encrypted data is then concealed in the least significant bits of color pixels using the LSB method. Augmented with the LCG method to randomly distribute the data bits within the bits of a PNG image, enhancing overall security. The images resulting from all processes are then evaluated by examining the matrix of the generated image (PSNR). A higher PSNR value indicates a better-quality image, and vice versa. All data hidden within the images can be retrieved precisely as the original condition when needed. The data used in this study consists of KPM photos in PNG format, with variations of hidden data in TXT format. All experiments conducted were successfully re-extracted only if the correct keywords were entered. The average PSNR value obtained from the experiments reached 77.230.
