Steganography is the art of concealing one digital media within another digital media and retrieving the information afterwards. There are many examples of usage: image into image, text into image, video into voice, voice into video, etc. This paper concentrates on a method used for hiding text into image using Least Significant Bit (LSB), and using a symmetric key between sender and receiver to choose which bits are needed to be embeded the text to minimize the resolution between the original image and the stego-image. Further this paper also explains about the security issues to the stego-image. Also the comparision of the performance of the algorithms (PSNR) have been discussed.
