<title>Advanced multimedia security solutions for data and owner authentication</title>

Abstract

In this paper we introduce a new content-fragile watermarking concept for multimedia data authentication, especially for a/v data. While previous data authentication watermarking schemes address single media stream only, we discuss the requirements of multimedia protection techniques. Furthermore we introduce our new approach called 3D thumbnail cube. The main idea is based on a 3D hologram over continuing video and audio frames. Beside the data authentication, we face the owner authentication problem as second requirement for manipulation recognition. The watermark for manipulation recognition has to be created by the owner itself. The goal of owner authentication is to ensure that an entity is the one it claims to be. Therefore we introduce a key server and a biometric hash approach. We discuss several strategies and introduce a biometric based framework for owner authentication. With our presented data and owner authentication solutions we can realize an advanced security level.
