A Deep Learning Approach for Steganalysis: Feature Selection Optimization and Classification using Sequential Backward Model, MILP, and ANN

Problem Definition

The detection of normal and stego images using machine learning algorithms poses a significant challenge in the realm of information security and data privacy. Steganography, the practice of concealing information within seemingly innocuous images, is a widely-used technique for secure communication. The difficulty arises in accurately distinguishing stego images from regular ones, as well as in effectively extracting meaningful insights from them. This task necessitates the development of robust classification algorithms that can reliably identify and analyze stego images, thereby enhancing the security and integrity of digital information. One of the key limitations in this domain is the vulnerability of conventional image processing techniques to sophisticated steganographic methods.

Traditional detection methods often struggle to effectively differentiate between normal and stego images, leading to potential security breaches and compromised data. Furthermore, the lack of efficient tools and methodologies for stego image detection hinders the overall effectiveness of information security protocols. By addressing these challenges, this project aims to contribute towards the advancement of steganography detection techniques, ultimately enhancing the protection of sensitive information in digital communications.
