Abstract

Secret data is more prone to unauthorized access when transmitted over the network. Hence data must be protected using some digital media protection scheme. Digital watermarking is now very popular in this field. Here we have proposed a new watermarking scheme to protect some secret messages by putting into a cover image during network transmission. The scheme is based on feed-forward back propagation neural network. The work is done in the frequency domain by considering 8×8 block of the image at a time. The neural network will be trained with spiral scan values of each block. Once the network has been trained it can be used to embed some secret message into any cover image and from the embedded image the message can again be extracted using the trained network. The proposed solution is highly effective and does not produce any visual deterioration of the cover image.
