摘要：Cryptography is a way to provide security to the message which is passed between the sender and thereceiver. It uses various algorithms to convert the actual message to an unreadable form. Steganography is an art ofhiding the message in an medium. The medium can be audio, video, image or even a graph. It gives the securitythrough the medium. The crypto-stegno communication uses both cryptography and steganography to send the messagesecretly from the sender to the receiver. This paper shows the usage of how message from sender is encrypted usingtriple DES through Unicode and hide the encrypted image into an stego image.. On the receiver end, extractionalgorithm is designed in such a way that the process separates the message and image into two different entities; thenreads the extracted message which is in the encrypted form and transforms it from the Unicode symbols to a readableform. The method is defined as undetectable, strong and secured communication of data related to the multimediaimage. Thus any confidential message can be send to any target without the knowledge of others through an unsecuredcommunication channel. This encoding and decoding scheme of the proposed new method is significantly different ascompared to traditional schemes
