In present times, the protection of multimedia data is becoming very important. The protection of this multimedia data can be done with encryption. There are so many different techniques should be used to protect confidential image data from an unauthorized access. In this paper, we are using multi encryption technique. Here we are using more than one encryption algorithm. First we apply segmentation process to divide the image in to 2n equal parts. These image parts are encrypted through encryption algorithm. In encryption for each image part we are using different encryption key. Now we add n bits to each image parts to identify it uniquely. Encryption keys are depends on additional bits. After encryption we are sending image parts through the network. At the receiver side first we extract the additional bits then we apply decryption algorithm into the image parts with the help of appropriate decryption key.
