A modified digital signature scheme for image authentication has been proposed. Content-dependent structural image features and wavelet filter parameterization are incorporated into the traditional crypto signature scheme to enhance the system robustness and security. Because the proposed scheme does not require any computational overhead, it is especially suited for wireless authentication systems and other real-time applications.

OUTPUT SCREENS:
- It is channel of sender side. It consist of different buttons such as Find Neighbour, Path discovery, select image and send.
2. Here we identify the neighbour channels based on those channels we identify the destination to send image.
3. Path Discovery button will display paths to receiver. Shortest path discover shortest path to send image
4. Here, we generate crypto signature by clicking on encryption. Finally we send the image to receiver then and image received message box is displayed
5. Here also we generate a signature which is changed compared to previous, because attacker attacked image in middle. Instead to verify it we generate a digital signature from image also.
6. Here also we generate a digital signature from image and compared with received signature. Here both are not equal so it will generate a message box Message attacked.
