Aim of the Experiment

To explore and reinforce the concept of steganography through the implementation of an alternate algorithm known as distortion steganography. This technique is aimed at embedding hidden information within digital media by making subtle, controlled modifications that are imperceptible to the human eye.

The primary goal is to understand how message concealment works at a deeper technical level using image transformations in the frequency domain, especially with Discrete Cosine Transform (DCT). Students will learn how data can be securely embedded and later extracted without alerting unauthorized viewers.

Applications

• Digital Watermarking: Used for copyright protection and ownership verification in images, videos, and other multimedia files.
• Covert Communication: Enables secure exchange of sensitive information without detection by unauthorized entities.
• Document Authentication: Verifies document integrity by embedding secure and invisible identifiers.
• Media Forensics: Helps in tracing unauthorized distribution of content and identifying tampered media.
• Stealth Data Storage: Stores confidential data within everyday media to avoid suspicion.
