Blockchain Enabled Interpolation Based Reversible Data Hiding Mechanism for Protecting Records

A diagnosis can be made using a lot of the crucial information contained in medical snaps. Medical images have become target for malicious attacks due to requirement regular communication order provide flexibility and accurate diagnosis. In protect images, encryption algorithms are used. Because this, photos encrypted before being transmitted; yet, this is only one layer security. Reversible Data Hiding (RDH) techniques recently been used incorporate private data into images. This enables efficient safe communication, secretly information—such as personal records—is highly helpful making However, limited embedding capacity current RDH systems continues limit their usefulness. study, method based on histogram shifting interpolation scheme highlighted. The achievable (EC) suggested technique bit per pixel (bpp) both digital blockchain-based system three keys encrypt proposed blockchain mechanism secure against outside threats. To verify utility strategy, outcomes compared cutting-edge photos. Along with hash value actual medicinal snaps, preserved blockchain. Due all transmitted through network may monitored. experiments analysis shows that has excellent security attained during entire process. It also achieved high capacity, PSNR, rate low SSIM throughout process concealing.
