Optimization of Steganography Techniques to Protect Important Information in Data Transmission

Abstract

Currently, social media has become an immensely popular platform, enabling users to share content, provide feedback, and interact with each other. Despite its convenience, the use of social media, particularly in sharing photos and videos, is often vulnerable to misuse due to a lack of security. Media security is crucial to prevent potential risks and undesired consequences. One effective way to enhance security is by implementing steganography techniques. Steganography involves a series of methods to conceal secret messages within cover files, making them undetectable in stego images. This research summarizes the latest methods in steganography techniques, focusing on utilizing cover files as containers to store secret information. The research findings indicate that the most commonly used method is Least Significant Bit (LSB) due to its ease of implementation, allowing for further development and combination with other methods or techniques to enhance security in hiding secret information. The analysis also reveals that the LSB method produces a lower average error rate compared to other methods.
