We present a Digital Rights Management (DRM) system that supports what you see is what you pay. In our system, multimedia is compressed with a scalable codec and encrypted preserving the scalable granularity and multiaccess capability. This paper focuses on the DRM modules enabling efficient key generation and management. We employ a light license server which stores only the master keys of con...

This paper describes SharedViews, a peer-to-peer data management system that simplifies file organization and facilitates file sharing and protection among home users on the Internet. The key innovation of SharedViews is the integration of queries and dynamic views from database systems with a capability-based protection model from the operating systems world. Users organize their files using v...

This paper presents a new approach to developing high availability (HA) server using Rapid Spanning Tree Algorithm and Protocol (RSTP) as specified in the IEEE 802.1w standard. The traditional approach requires the use of multiple IP addresses and complex management software to monitor multiple links. If there is a link failure, the management software requires to perform complex fail-over func...

The content distributors take content protection and Digital Rights Management of content very serious. As such many provisions already exist to make sure content is securely sent to, and only to, licensed clients. In this paper an alternative content encryption system is proposed by using the homomorphic features of asymmetric cryptography systems. Using a split-key derivative of the RSA crypt...

Universal Multimedia Access (UMA) calls for solutions where content is created once and subsequently adapted to given requirements. With regard to UMA and scalability, which is required often due to a wide variety of end clients, the best suited codecs are wavelet based (like the MC-EZBC) due to their inherent high number of scaling options. However, most transport technologies for delivering v...

The Identity Metasystem is an interoperable, platform independent and protocol independent architecture for user centric identity management. User centric identity management is a new paradigm of identity management that addresses some of the drawbacks of the prevalent identity management models. This technology assumes that certain security sensitive functions of identity management are perfor...

Wide Area Networks have different performance characteristics compared with Local Area Networks. Their throughput is usually lower and there is a greater chance of information being dropped, damaged or delayed. Furthermore software that is developed for dependable applications over wide area networks may frequently be tested in a LAN environment where it is difficult to reproduce the characteri...
