SECURE AND ROBUST IMAGE WATERMARKING USING ENCRYPTED REVERSIBLE DATA HIDING

Abstract

In this technique, picture watermarking is utilized to give the ownership security. And furthermore the negative secret phrase gives the wellbeing to the watermarked picture. In this structure, the ordinary plain secret key from a client is hashed during a cryptographic hash work. At that point, the hashed secret phrase is changed into a negative secret phrase. At last, the negative secret phrase is scrambled into an Encrypted Negative Password utilizing a symmetric-key calculation, and multi-emphasis encryption could be working to extra improve security. The cryptographic hash work and symmetric encryption make it hard to break passwords from ENPs. Besides, there are bunches of coordinating ENPs for a given plain secret word, which makes pre calculation assaults infeasible.
