Improving the non-filtering steganographic algorithm using LSB verification method

摘要

Steganography is the art or practice of concealing secrete information into a cover media like text, protocol, file etc. In our proposed algorithm, a new Steganographic technique is developed to hide large amount of data in Bitmap image using the concept of LSB verification method. This method uses first three color components to detect the actual position of the secret bit into the fourth color for embedding and extracting data. This method uses adjacent three colors of image pixels to define the embedding position of message bit into the forth color.
