A Novel Approach of LSB Based Steganography Using Parity Checker

For hiding secret information in images, there exist a large variety of steganographic techniques, some are more complex than others and all of them have respective strong and weak points. In the proposed method, all pixels of the cover image can be used but message bit is stored in LSB of one of the three color components, Red(R), Green(G), Blue(B) based on the parity of three LSBs of R, G, B components of 24-bit color image.The proposed work uses the concept of parity method for hiding and recovering secret data or information. The proposed method can hide large volume of data in a single RGB image with changes in only few pixels of input image retaining the advantages and discarding the disadvantages of traditional LSB method.
