Abstract

Steganography transmits data by actually hiding the existence of the message so that a viewer cannot detect the transmission of message and hence cannot try to decrypt it. During communication process LSB steganography based on Huffman encoding algorithm does not provide full security and good compression. So a secure DCT-based steganographic algorithm is proposed in integration with neural network. This algorithm provides more security and compression by combining cryptography with DCT-steganography. The proposed technique has two main algorithm i.e. Embedding Algorithm and Extraction algorithm. The whole simulation has taken place in MATLAB environment. The performance parameters are PSNR and MSE.
