The project group Constitutionally Compatible Technology Design (provet) under the direction of Prof. Dr. Alexander Roßnagel carries out interdisciplinary research projects on legal issues arising in the field of information and communication technology. Therefore, the project group is part of the Interdisciplinary Research Center for Information System Design (ITeG) alongside with several other technical Partners. At the present time, there are 20 legal scholars in the project group. The research agenda is to support the development of legally compatible technology. Within the framework of practical research projects, technical design proposals are being developed for technical systems and infrastructures, such as ISDN units, electronic signature algorithms, multimedia system models, electronic methods of payment, chipcards, biometric systems, mobile communication, internet shops and electronic marketplaces. In this way, compliance with legal requirements can be ensured. Conversely, appropriate legal regulations have become a central requirement for the implementation of new technologies, especially in the case of ICT. The second research agenda is thus to support a development of law that is adapted to meet the changing general conditions specified by the development of technology. In this respect, the projects aim at the establishment of technically suitable regulation concepts and legal recommendations, like in the past, e.g. for the laws of electronic signature, tele service data protection, data protection auditing and the new German electronic ID card. The projects are being funded and promoted by ministries, other public authorities, foundations, enterprises and the German Research Foundation (DFG).
