Image Steganography Using Least Significant Bit (LSB)

Abstract

Image steganography is the process of hiding information, which can be text, image, video or audio inside a cover image. In this paper I have proposed an approach of image steganography called the LSB (least significant bits) method. This method uses the least significant bit of image and replaces them with the bits of the information to be hidden. There is also and image quality enhancement method to enhance the image resolution if the resolution of stego image is affected. I have compared this technique with some other methods of steganography in this paper. Keyword: - Steganography, image steganography, LSB, encryption, decryption.
