Summary of Trial

The issues of performance, ease of integration and compatibility are investigated in the following demonstrations and trials:

• Migration to UMTS from GSM is being investigated firstly by assessing the validity of a joint protocol and, secondly, by investigating the implementation of a migratory UIM, which will be compatible with both networks.
• Evaluation and comparison of different fraud detection techniques. Both rule-based and neural network-based approaches are being investigated. In each case user profiles, based on previous behaviour, can be built up so that unusual behaviour can be detected and automatically labelled as suspicious.
• Verification that the TTP concept is viable and can be introduced safely and effectively. The TTP will be used to support secure billing and escrowed key establishment between a user and a value added service provider. The trial will be carried out in conjunction with the AC013 EXODUS project. The trial configuration is illustrated in the diagram, that shows a TTP emulator which may interact with a value-added service provider and an end user.
• Investigation of user-to-UIM verification using biometric techniques.
