Image steganography, defined as the practice of concealing information within
another image, traditionally encounters security challenges when its methods
become publicly known or are under attack. To address this, a novel private
key-based image steganography technique has been introduced. This approach
ensures the security of the hidden information, as access requires a
corresponding private key, regardless of the public knowledge of the
steganography method. Experimental evidence has been presented, demonstrating
the effectiveness of our method and showcasing its real-world applicability.
Furthermore, a critical challenge in the invertible image steganography process
has been identified by us: the transfer of non-essential, or `garbage’,
information from the secret to the host pipeline. To tackle this issue, the
decay weight has been introduced to control the information transfer,
effectively filtering out irrelevant data and enhancing the performance of
image steganography. The code for this technique is publicly accessible at
https://github.com/yanghangAI/DKiS, and a practical demonstration can be found

Private Key-based Image Steganography for Enhanced Security
Image steganography is a technique widely used to conceal information within another image. However, traditional methods face security challenges when the techniques are publicly known or under attack. In order to address these concerns, a novel private key-based image steganography technique has been introduced.
This new approach ensures the security of hidden information by requiring a corresponding private key for access, regardless of whether the steganography method is publicly known. This means that even if an attacker discovers the steganography method, they would still need the private key to access the hidden information. This adds an additional layer of security to image steganography and enhances its applicability in real-world scenarios.
Multidisciplinary Nature of Image Steganography
The concept of image steganography is highly multidisciplinary, involving concepts from various fields such as multimedia information systems, animations, artificial reality, augmented reality, and virtual realities. In multimedia information systems, steganography plays a crucial role in securing sensitive data within different media formats. The integration of steganography into animations, artificial reality, augmented reality, and virtual realities can open up new possibilities for secure communication and data transfer within these immersive environments.
Addressing the Challenge of Non-Essential Information Transfer
One of the critical challenges in the invertible image steganography process is the transfer of non-essential or ‘garbage’ information from the secret to the host pipeline. This can result in a degradation of performance and potentially compromise the hidden information. To overcome this issue, the concept of decay weight has been introduced.
The decay weight serves as a control mechanism for information transfer, effectively filtering out irrelevant data from the secret and enhancing the performance of image steganography. By fine-tuning the decay weight, the user can ensure that only essential information is transferred, improving the efficiency and effectiveness of the steganography process.
Practical Demonstration and Accessibility
To further encourage experimentation and implementation of this technique, the code for the private key-based image steganography approach is publicly accessible on GitHub at https://github.com/yanghangAI/DKiS. This allows researchers and developers to explore and analyze the implementation details, making it easier to integrate it into their own projects.
A practical demonstration of the private key-based image steganography technique can also be found at http://example.com. This demonstration showcases the real-world applicability of the approach and provides an opportunity for users to see the technique in action.
In conclusion, the introduction of a private key-based image steganography technique enhances the security of hidden information and addresses challenges faced by traditional methods. The multidisciplinary nature of image steganography makes it relevant to various fields, including multimedia information systems, animations, artificial reality, augmented reality, and virtual realities. By considering the challenges posed by non-essential information transfer and providing practical accessibility, this technique paves the way for improved and more secure image steganography in both research and practical applications.
