Separable Reversible Data Hiding in Encrypted Image Using Dual Data Embedding with Histogram Shifting

In Digital Communication, the information being transferred from the sender to receiver is not secure. Intruders attempt to steal data at any moment. Maintaining security and confidentiality is much important. For protecting privacy and security from unauthorized users, masking the data in the network is essential. Data hiding in image is mainly used to cover the privacy. It uses some manipulation methods to hide secret data. Histogram Shifting enhances the data hiding capacity. Image scanned pixel by pixel in order to embed data. Most reversible data hiding methods not involve the sender for data embedding. In this paper, secure separable reversible data hiding is used along with dual data embedding i.e. embedding data before and after encryption. Separable reversible data hiding technology in encrypted image (SRDH-EI) also has been developed extensively because of its better practicability. The experimental results showed that our proposed scheme achieved better hiding capacity than the other schemes.
