High-Payload RDH Technique for Secure Data Transmission Through Improved Context Pixel-Based PVO Exploiting Center-Folding Strategy
摘要
In this study, a center folding method and context pixel-based PVO (CPPVO) are used to provide a large capacity reversible data hiding technique for safe data transfer. Dual Marked Images (DMI) were initially created by inserting concealed information into an interpolated cover image using the center folding approach. More hidden information on Dual Marked Images is then included using context pixel-based PVO. In this instance, the center folding strategy was chosen because to its ability to compress significant hidden information using averages. CPPVO, on the other hand, provides the capability to embed an image block with over two pixels by applying context and neighboring pixels. The proposed method is highly flexible due to the fluctuating amount of the secret data and the size of various picture block needed for efficient embedding process. In the experiment, findings show that the proposed method Improved Context-Pixel-Based PVO (ICPPVO) that uses the center folding approach is especially suitable for embedding more hidden information without giving in the picture quality in comparison to earlier state-of-the-art approaches. The anticipated result revealed a number of exceptional skills in the areas of digital forgery detection, tamper detection, and covert data transfer, all of which are crucial to the advancement of technology. A number of public and private sector areas, including defense, health care, business security, as well as intellectual property rights, would gain tremendously from this initiative.
