Steganography Technique

A message is hidden in an image and send to the recipient. The recipient again uses the same technique to extract the message from the image.
I used EXOR operation of each and every bit in message with the least significat bit of pixels in the image. So that after encryption there wont be any modifications in the image so that an observer can not differentiate the original image and the encrypted image.So a secured transmission of message can be achieved.
