Advanced Communications and Multimedia Security offers a state of the art assessment of present views in addition to the most recent advancements within the quarter of communications and multimedia protection. It examines necessities, concerns and strategies pertinent to securing info networks, and identifies destiny security-related examine demanding situations. a large spectrum of issues is mentioned, together with:
-Applied cryptography;
-Communication structures protection;
-Applications safety; cellular safety;
-Distributed platforms defense;
-Digital watermarking and electronic signatures.

This quantity includes the complaints of the 6th Joint operating convention on Communications and Multimedia defense (CMS'02), which was once backed by means of the foreign Federation for info Processing (IFIP) and held in September 2002 in Portoroz, Slovenia. It constitutes crucial studying for info safeguard experts, researchers and pros operating within the quarter of machine technological know-how and communique systems.

It avoids using secure multi-party computations. Further research directions are also suggested. Keywords: Copyright protection, Asymmetric fingerprinting, Secret sharing 1. INTRODUCTION Recent years have seen a rapid growth in the availability of multimedia content in digital form. They can be easily duplicated and redistributed. Thus there has been an increasing interest in developing copy protection or copy deterrence mechanisms. Digital watermarking has been proposed for the purpose of copyright protection for multimedia content.

CONCLUSIONS In this paper we present a new idea for asymmetric fingerprinting based on secret sharing. We also describe an idea for the underlying fingerprinting scheme. When the digital data to be fingerprinted is large, A New Asymmetric Fingerprinting Framework Based on Secret Sharing 39 our framework is quite efficient. Our future research will include to devise fingerprinting methods satisfying the assumption for the underlying fingerprinting scheme in the framework. In addition, though the trust requirement for FlO is lower than that for a real TTP, it is still necessary to make some trust assumptions on FIC in our framework.
