An efficient and adaptive data-hiding scheme based on secure random matrix.

Area of Science:

• Computer Science
• Information Security
• Digital Image Processing

Background:

• Existing data hiding techniques often require pre-encryption, posing security risks if the embedding algorithm is compromised.
• Current methods lack flexibility in adapting to varying data hiding capacities and image quality requirements.

Purpose of the Study:

• To propose an efficient and adaptive data hiding scheme that enhances security and visual quality.
• To introduce a novel 'secure reference matrix' for robust data embedding in digital images.

Main Methods:

• Development of a new data hiding scheme based on a randomly generated secure reference matrix.
• Implementation of a flexible protocol allowing adjustable data hiding capacities and image quality.
• Performance analysis through practical testing and comparison with existing methods.

Main Results:

• The proposed scheme demonstrates superior flexibility and efficiency in the data embedding process.
• Stego-images generated by the scheme exhibit higher visual quality, indicated by improved Peak Signal to Noise Ratio (PSNR) values across different capacities.
• The randomized nature of the secure reference matrix significantly increases resistance to exhaustive attacks.

Conclusions:

• The novel secure reference matrix-based data hiding scheme offers enhanced security and flexibility.
• The method provides a practical solution for secure digital message delivery with high visual fidelity.
• This approach represents an improvement over existing data hiding techniques in terms of security and performance.
