Recently, numerous novel algorithms have been proposed in the fields of steganography and visual cryptography with the goals of improving security, reliability, and efficiency. Privacy in communication is desired when confidential information is shared between two parties. Mainly this project uses DCT, IDCT, neural networks and visual cryptography. The proposed system provides multilayer security. The level of security is achieved by using steganography followed by visual cryptography. The secret image is embedded into the cover image. Then the encrypted image is divided into 3 shares. If the secret key valids, first share will be displayed. By analyzing the finger print and knuckle print, the embedded image obtained by combining the remaining shares and the extracted secret image will be displayed respectively. This project is implemented using Matlab
