LSB Based Steganography Model for Medical Images

Abstract

This paper presents a steganographic model in medical system using LSB method. The LSB scheme takes the first LSB bit of the gray scale image and first message bit from the message matrix (Patient information) and embeds the message into the original image. After insertion of first message bit, pixel location of image and message is incremented by one. This process continuous itself till the message length is not equal to zero. Different medical images are taken for experimental result. Image is passed from one doctor to another after embedding their respective prescription in it. The experiment is performed on the seven medical images and the result is obtained.
