A Proposed Method In Image Steganography To Improve Image Quality With Lsb Technique

Abstract: Image steganography is becoming an important area in the field of steganography. As the demand of security and privacy increases, need of hiding their secret information is going on. If a user wants to send their secret information to other persons with security and privacy he can send it by using image steganography. During the last few years lot of different methods of hiding information has been done in this field. Some of the existing methods for hiding information give good results only in case of information gets hidden successfully.
LSB is the most popular Steganography technique. It hides the secret message in the RGB image based on it its binary coding. LSB algorithm is used to hide the secret messages by using algorithm. LSB changes the image resolution quite clear as well as it is easy to attack. It is clear that LSB changes the image resolution when the least significant bits add in the binary image format, so that image quality become burst and there become so much difference in the original image and encoded image in the respect of image quality.
So to overcome this problem, In this thesis I suggested modifying the LSB technique so that we can get same image quality as it has before the encoding. The basic idea to get good image quality, I am going to modify the hiding procedure of the least significant bit. In this step I will hide two bits by two bits by taking identical values.
