Abstract: In today’s technology data hiding has become an essential need due to the availability of the internet all over the world. Nowadays, it has become necessary task for the people to communicate through networks and share contents with each other. In the meanwhile, transferring the data in a secured manner has become a challenge and also a paradigm. Still there exists many ways for hiding the data in an encrypted images. Hiding information at the back end of the image should not affect the original data or image pixels. It is one type of steganographical method where the data can be hidden inside the images and original data can be losslessly retrieved after extracting the embedded text.The proposed work discusses encryption using reversible data hiding and produces an outlineof various reversible data hiding techniques which includes quantization technique, histogram shifting, expansion technique, compression technique anddual image technique.
Keywords: Encrypted images, Reversible data hiding, Embedded image, histogram shifting, dispersion, interpolation, watermarking.
