Tracing Authors' Rights by Labelling Image Services and Monitoring Access Networks Main Objective
TALISMAN aims to provide European Union service providers with a standard copyright mechanism to protect their digital products against large scale commercial piracy and illegal copying. With the increasing availability of digitally stored information and the development of new multimedia broadcasting services, security questions are becoming ever more urgent. The acceptance of new services depends on whether suitable techniques for the protection of the information providers' interests are available. One problem that has not found a solution yet is the one of how to realise copyright protection for digitally stored data.
To this aim, the TALISMAN project is setting up an evolving and open framework based upon authors' societies, contents providers and broadcasters requirements allowing integration of a hierarchy of solutions for protecting video contents. Instances of such solutions encompassing low end systems based upon header description associated with the bit stream (called labelling) up to high end sophisticated, holographically inlayed, undeletable systems (called watermarking) will be developed within the TALISMAN project. Associated hardware implementation to support and exploit such realisations in a cost efficient way will be provided. Exploitation is performed through a dedicated equipment called monitoring.

Technical Approach

Labelling
This is add-on public information over a work enabling a number of functionalities:

Labelling shall be carried within a work from its design up to its final exploitation in order to guarantee full consistency.

Watermarking
In order to ensure copyright protection, hidden secret information should be associated with one picture. This information is only accessible to authorized people in charge of this picture's copyright protection. Watermark will be used by an author either to detect automatically whether his work has been used out of his control or to provide evidence for his rights regarding a work.

Monitoring
A monitoring device is a piece of equipment enabling automatic analysis and exploitation over labels and watermarks. Two kinds of monitoring are envisaged:

Summary of Trial
An important characteristic of the TALISMAN project is that it will prove the applicability of the techniques not only in laboratory conditions but also in close-to-real conditions of broadcasting. This should demonstrate that the solutions are fully resistant to different broadcasting conditions, which has never been experimented before. The major near term networks will be addressed: cable, satellite for video transmission, extended to ATM networks for interactive services access.
Monitoring devices enabling accounting, auditing and tracing over these networks also constitute an important output of the TALISMAN project.
The project focuses on video services and will demonstrate the relevance of the mechanisms around pilot demonstrations covering the major future broadcasting media: terrestrial CATV network for video transmission, satellite broadcasting, ATM network for multimedia interactive services access.

Key Issues

Achievements

Actual achievements
Software systems for protecting a video sequence (label and watermark) and analysing their retrieval after compression.

Expected achievements

Expected Impact
TALISMAN should provide the answers to the issues regarding the protection of authors and the management of their rights. It is one of its major objectives to specify a standard copyright mechanism in Europe for video protection to be submitted to DAVIC. The availability of copyright systems managed in a harmonized way will be essential for all the end users in the field: TV broadcasters,producers of movies, cassettes, video CDs and interactive CDs.
