DKiS: Decay weight invertible image steganography with private key

Area of Science:

• Computer Science
• Information Security

Background:

• Image steganography is the practice of concealing information within an image.
• Existing invertible image steganography methods face challenges in performance and security.

Purpose of the Study:

• To propose a novel invertible image steganography model with enhanced performance and security.
• To introduce a decay weight mechanism and preset private key integration.

Main Methods:

• Implemented a decay weight mechanism to filter non-essential information during data transfer.
• Integrated a preset private key for secure access to concealed data.
• Developed a high-capacity image steganography model.

Main Results:

• The decay weight mechanism effectively filters irrelevant data, improving steganography performance.
• Preset private key integration significantly enhances the security of hidden information.
• Experimental results demonstrate the model's robustness and practical applicability.

Conclusions:

• The proposed decay weight invertible image steganography with private key (DKiS) model offers a significant advancement in secure and efficient information hiding.
• DKiS addresses key challenges in current steganography techniques, providing a robust solution for real-world applications.
