Survey on Image authentication based on Reversible watermarking and Perceptual hashing
Keywords:
Reversible Watermarking, Perceptual Hashing, Image Authentication, Hiding Capacity, Mean Value based Embedding.Abstract
Accessibility of digital content in this digital era is simpler hence navigates towards a threat for
unauthorized access. Vulnerable use of such contents can harm the integrity and confidentiality of data. Reversible
watermarking provides the regeneration of original image in addition to watermark. Perceptual hashing supports the
multimedia file security in an efficient way. Combination of the above provides efficient, secure and high embedding
capacity.
