Secure Reversible Data Hiding in Scrambled Pictures by Reserving Room before Encryption

Today reversible information stowing away in encoded pictures by holding room before encryption is a very significant method is use in different utilization of safety. Where information security is essential vital. These instruments are essential use in inelegancy organization. At some point when we manage an information and that information is noticed ob outsider client and that circumstance you need to shroud information specifically component that time we can utilize this reversible information covering up in scrambled pictures by holding room before encryption strategy. In this paper, we propose a novel technique by holding room before encryption with a conventional RDH calculation, and in this manner it is simple for the information hider to reversibly install information in the scrambled picture. The proposed technique can accomplish genuine reversibility, that is, information extraction and picture recuperation are liberated from any blunder. Analyses show that this novel technique can insert more than 10 times as enormous payloads for a similar picture quality as the past techniques, for example, for  PSNR dB.
