摘要：These Steganography is the art of hiding the existence of data in another transmission medium toachieve secret communication and Reversible Data Hiding (RDH) in images is a technique by which the image can beretrieved back after extracting the secret messages embedded in it. The present methods involve reserving room for thesecret message before encrypting the message into the cover image. so that the cover image can be effectively retrievedafter extracting the secret message by the receiver. But the method involves some disadvantages which reduces theefficiency of this method. The primary disadvantage that the key generation used in Reversible data hiding method isby using random value. When the random value is used in key generation, it can be effectively regenerated by theinvaders. So this proves to be inefficient in security. In this paper we propose a new method in which we make useRivest-Shamir-Adleman algorithm for the key generation which effectively increase the security as the key generationis difficult. This method can also be used to encrypt the message in the video also. The security is highly improve in thenew method which is proved by using various experiments. Today reversible information stowing away in encodedpictures by saving room before encryption is an imperative method is use in different use of security. Whereinformation security is essential imperative. This instrument is essential use in inelegancy office. At some point whenwe manage an information and that information is watched outsider client and that circumstance you need to shroudinformation specifically system that time we can utilize this reversible information stowing away in encoded picturesby holding room before encryption procedure. In this paper, we propose a novel strategy by holding room beforeencryption with a conventional RDH calculation, and in this manner it is simple for the information hider to reversiblyinsert information in the scrambled picture. The proposed technique can accomplish genuine reversibility, that is,information extraction and picture recuperation are free of any blunder. Tests demonstrate that this novel technique canimplant more than 10 times as vast payloads for a similar picture quality as the past strategies, for example, for PSNRdB.
