A Detailed Survey on Bit Plane Complexity Segmentation (BPCS) and RSA Algorithm for Secured Medical Data Transfer

For computer users, data security is a major concern. In the medical field the data must be present in a hidden form rather than original. Each of us has essential medical data that we want to keep safe from others. Bit Plane Complexity Segmentation (BPCS) is described in this article as a method for hiding information within images in various planes. The algorithm can be used with the RSA public key encryption scheme to enhance security in data transmission. It is important to determine a threshold (approximate) value so that the stego and original images are the same, and so that the hiding capacity is greater with less computing cost. This process imposes a number of restrictions. This paper presents two modules encryption and decryption while transferring medical text in a hidden mode. Error rate is calculating with PSNR, BER and MER with three bit planes Red, Blue and Green.
