In this paper, we are going to have survey on different data hiding techniques and our main focus is on” Reversible data hiding in encrypted images”. In recent year the security of the sensitive data has become of prime and supreme importance and concern. To protect this data or secret information from unauthorized person we use many data hiding techniques like stegnography, cryptography and RDH. In this paper we will discuss on one such data hiding technique called Reversible Data Hiding (RDH). In this instead of embedding data in encrypted images directly, some pixels are estimated before encryption so that additional data can be embedded in the estimating errors. Without the encryption key, one cannot get access to the original image. A RC4 algorithm is applied on the rest pixels of the image and a special encryption scheme is designed to encrypt the estimating errors.Our paper presents a survey on various data hiding techniques and their comparative analysis.
