Our system will have new features to overcome the above mentioned issues. The transactions will take place in a secured format between various clients. It provides flexibility to the user to transfer the data through the network very easily by compressing the large amount of file. It will also identify the user and provide the communication according to the security standards. In this system the data will be sent through the network as an audio file. The user who receives the file will do the operations like de-embedding, decryption, and uncompression in their level of hierarchy and get the required information. Compressing the data will increase the performance of the transfer and embedding the encrypted data in the audio file in such a way that the audio file pretends as normal audio file will assure the security while the transfer takes place. …show more content…
The content owner first encrypts the original image using an encryption key to obtain an encrypted image. Then, the data-hider compresses the least significant bits (LSB) of the encrypted image using a data-hiding key in order to create a sparse space to accommodate some additional data. At the receiver side, the data embedded in the created space can be easily retrieved from the encrypted image according to the data-hiding key. Since the data embedding affects only the LSB, a decryption using encryption key can then result in an image similar to the original one. By using both the encryption and data-hiding keys, the embedded additional data can be successfully retrieved and the original image can be perfectly recovered
