Digital Image Processing

Abstract

A major issue for the computer networks is to prevent the information from Threats. To secure the information, cryptography technique has been implemented. By using this technique, data can be encrypted over the network during transmission. Once the data has been sent to the destination, the authorized person (user) will decrypt the data along with the key. The data can be in the form of text, image, audio etc... Visual cryptography technique has been implemented for image. Using the visual cryptography technique, fake passport can be identified. The image can be encrypted and the decryption will be done by the immigration department to identify whether the passport is real or not.
