摘要：In today's digital world , exchange of information is been held electronically. Therefore there arises the great need for secure transmission of the concerned data. Various practices like cryptography, watermarking, compression etc. are common since past few years. All these techniques were proved to be excellent in their respective work regarding security. In this paper a new approach has been presented to provide security at enhanced level. Here the two techniques namely watermarking and compression are combined together to enhance the level of security for data transmission purpose. Here the watermarking using DCT technique is been combined with image compression technique using improved adaptive Huffman encoding. The improved adaptive Huffman coding technique is been based on Huffman algorithm. This new compression algorithm not only reduces the number of pass required to encode the data but at the same time reduces the storage space in comparison to adaptive Huffman and static Huffman respectively.
