Abstract

COMPRESSION AND DATA HIDING SYSTEM BASED ON SMVQ

Sapatnekar Aparna A.* and Prof Mantri D. B.

ABSTRACT

There are many digital multimedia transmissions on the network. Therefore to protect the secret messages during transmission becomes an important issue. To guarantee communication efficiency and save network bandwidth compression techniques can be implemented to reduce redundancy and the quality of the decompressed versions should also be preserved. Here a novel system is shown for compression and data hiding using side match vector quantization (SMVQ). On the sender side, except for the blocks in the leftmost and topmost of the image, each of the other residual blocks in raster-scanning order can be embedded with secret data and compressed simultaneously by SMVQ.
