Implementation of Steganography with ETC System for Different Data Transmission

Gauri Chavan, S. S. Vairagar

Abstract: Data transmission in a secure manner over the internet has gained higher interest since last decade as the use of encryption for transmitting embedded files before compression is very essential. The major challenge is designing the architecture so as to perform the file encryption at sender side and the file compression at the NSP side in order to achieve the distinguished works assigned to senders and NSP. The proposed architecture comprises a novel architecture where resources required for file compression are utilised from NSP quota while resources only for encryption are used from Sender quota. The proposed system makes use of pre-defined AES encryption algorithm for encrypting the files and LSB Steganography for hiding the sensitive data in the images. With the AES, mathematical technique is more productive for efficient compression of files that are been already encrypted. While as far as compression is concerned, Huffman algorithm is not feasible, as it gives less compression proportion, compared to the other lossless coders as inputs.
