Data hiding technique by using RGB-LSB mechanism

Internet is the most popular communication medium now a days but communication over the internet is facing some problem such as data security, copyright control, data size capacity, authentication etc. Separable reversible data hiding technique means separating two major activities in the scheme. These two activities are getting the exact recovery of the secure hidden data and exact recovery of cover data. Here we introduce a novel scheme for separable reversible data hiding in encrypted domain in which we use image as a cover medium and image as a data to be hid. The scheme´s main feature is the way of data embedding into the encrypted cover image. Here we are concentrating on using RGB-LSB method for data embedding and finally verifies the performance of using RGB-LSB method in terms of Quality index Q, PSNR etc.
