Sayli P. Raut, Kiran A. Bhandari . Vacating Room before Encrypting of Image for Reversible Data Hiding. International Journal of Applied Information Systems. 11, 3 ( Aug 2016), 46-49. DOI=10.5120/ijais2016451589
Abstract
Data confidentiality and integrity have become most important aspect of this communication world. Where, cryptography involves both encryption and embedding of data, the main aspects to keep the data integrity and confidentiality intact. Encryption domain has more importance in data hiding. Data concealing can be done through any channels like audio, video, image etc. and send to receiver. Receiver will acquire data from the media where it embeds data. Data hiding can be done for sending highly classified data. For which Reversible Data Hiding is becoming more popular. Reversible data hiding is an approach by which the original image can be recovered without any loss when the data embbeded in it is extracted. This paper focuses on main approaches of RDH i.e. Vacating Room after Encryption and Vacating Room before Encryption and compares the performance of same on the basis of various RDH techniques.
