This requires urgent multi- disciplinary debate on the collection, control and use of personal data in society. This paper proposes a framework that can be used to shape this dialogue. It is based on a neutral and consistent terminology that may support a constructive and fruitful debate, avoiding terms that have too often led to controversy and confusion. We have attempted to position in this structure state-of-the-art technology devel- opments, including context-awareness, user-centred data management, trust net- works and personal data ecosystems. It demonstrates clear relations between ongo- ing work in various groups and hence an urgent need for cooperation to achieve common goals. We argue that such cooperation can lead to the emergence of a personal data ecosystem that may truly support a sustainable digital society.

It is based on a neutral and consistent terminology that may support a constructive and fruitful debate, avoiding terms that have too often led to controversy and confusion. We have attempted to position in this structure state-of-the-art technology developments, including context–awareness, user-centred data management, trust networks and personal data ecosystems. It demonstrates clear relations between ongoing work in various groups and hence an urgent need for cooperation to achieve common goals. We argue that such cooperation can lead to the emergence of a personal data ecosystem that may truly support a sustainable digital society.

The two most attractive features of the 16-CAP transceiver are its capability of operating in the presence of multiple users in a voice-grade UTP cable and the straightforward way in which it can provide scalability to lower speeds. It is also shown in the paper how the carrierless AM/PM (CAP) modulation scheme used for the ATM LAN standard can be utilized to provide substantially higher data rates than 51 Mb/s when there is only one user in a cable. Under this condition, data rates up to 155 Mb/s can be achieved over category 3 wiring and significantly higher rates can be achieved over high-performance category 5 wiring

The network architecture considered here id fiber to the curb, and local distribution of the IMTV signals to and from the home is provided on telephone wiring and coaxial cable. The downstream IMTV channel, from the curb to the home, operates at a data rate

The downstream IMTV channel, from the curb to the home, operates at a data rate of 51.84 Mbps, and the upstream channel, from the home to the curb, operates at a data rate of 1.62 Mbps

One of the areas on the verge of expansion is electronic commerce (EC(. While still in its infancy, EC is forecasted to increase by over an order of magnitude over the next several years. Notable success stories of selling over the Web—such as those of amazon.com and Dell Computer—are often touted today. A major concern with the creation of EC systems today is the large amount of customization and systems integration work required. We present here the MediaXact™ system, a solution to this dilemma that provides a framework separating the service presentation and service logic from the functions that make up the service. This greatly simplifies customization and eases the integration with existing legacy systems and business logic.

Research paper thumbnail of MCMP: A Transport/Session Level Distributed Protocol for Desktop Conference Setup

This paper describes the MCMP conference setup algorithms and proves that they meet specified correctness properties. MCMP sets up control channels for use in exchanging control information while the conference is in progress. The logical topology used is a completely interconnected mesh. MCMP always provides best effort services in cases of failures. Correctness properties guaranteed upon termination of the protocol include connectivity, validity, uniqueness, and consistency of local views. Application control information that can be exchanged using the control channels include resource negotiation and subconferencing.

This year the focus of the Yearbook is “social networks and social machines, surveillance and empowerment.” In what is now the well-established tradition of the Yearbooks, different stakeholders in society and various disciplinary communities (technology, law, philosophy, sociology, economics, policymaking) bring their very different opinions and perspectives to bear on this topic, forming a basis for inspiring and constructive cross-disciplinary discussions.
