摘要：The traditional cryptographic algorithms both symmetric encryption and asymmetric encryption algorithms do the conversion of data into a cipher text for transmission over a public network. Most cryptography algorithms change the original plain text into a cipher text via an encryption algorithm and transmitted over the network. This cipher text is decrypted at the other end. Since the transmitted cipher text is visible in the network, it may be subjected to attacks. To overcome this problem, we implement a technique of hiding the message in the image file or in the video file in such a way that there would be no perceivable changes in the image or video after the message insertion. Sometimes the message is encrypted and hidden in the image or video file raises the level of security. This process of hiding message in the image or video file is called steganography. For this a new steganography technique called Joint Visual Cryptography (JVC) is implemented. This does not blur or change the image so that during transmission of image no one recognize the data, after receiving transmitted image receiver decrypt the original message from the image.
