A Study on Reversible Fragile Image Watermarking Scheme

Abstract: Digital watermarking is the way that is used to protect the confidential information in the form of images from the hackers or intruders. Images like medical images, military images contain vital information they must be protected from modification and attacks. Irreversible watermarking schemes have various limitations such as permanent embedding distortion. The problem of the embedding capacity depends on signal, that is the capacity of embedding depends on nature of the host signal and the block-wise dependence problem were not addressed by the researches of reversible watermarking schemes. This work proposes a reversible watermarking scheme which reduces the discussed limitations of irreversible and reversible schemes with different parameters.
