PSO (Particle Swarm Optimization) Based Reversible Data Hiding

Text fusion in images is an important technology for image processing. We have bulks of important information related to the reports and need lots of space to store and the proper position and name which relates that image to that data. The principle of separable reversible data consists of three steps in a first step we encrypt the host image with the help of encryption key, then in a second step we hide a text in image with data hiding key and in the last step we extract the data and recover the original image. The proposed work is based on AOI (area of interest). AOI is calculated with the help of particle swarm optimization for the particular image and will fuse the related document in that position or area and in this we use a text as a hidden data.
