Secure Data Communication Through Improved Multi-level Pixel Value Ordering Using Center-Folding Strategy

In this research, a high capacity reversible data concealing strategy has been developed for secure data transfer utilizing multi-level pixel value ordering (MPVO) and center-folding strategy. Center-folding strategy was first used to insert hidden information into an interpolated cover picture, creating dual marked images (DMI). Subsequently, multi-level pixel value ordering uses to incorporate more hidden information on dual marked images. The center-folding approach has been used in this case because it offers the benefit of compressing important hidden information via averaging. By using neighboring and reference pixels, MPVO, on the other hand, offers the ability to embed an image block with more than two pixels. The secret data’s changing size and the varying picture block sizes required for effective embedding make the suggested technique very adaptable. In comparison with the previous state-of-the-art approaches, the experimental results reveal that the suggested method is particularly suited for embedding more concealed data without degrading the visual quality of the picture. The expected outcome brought to light several outstanding capabilities in the fields of covert data transmission, tamper detection, and digital forgery detection, without which the development of technology would be severely hindered. This program greatly benefits several aspects of the public and corporate sectors, such as health care, business security, defense, and rights to intellectual property.
