Security-based approach to data consistency in a virtual enterprise

Summary form only given. The consistency of information is one of the hottest topics in the science and practice of information systems, especially in virtual enterprises. Virtual enterprise modelling attracts a lot of attention from researchers and professionals in software engineering, information system, and business-oriented computer science. Amongst the strong interest in virtual enterprise is the achievement of the consistency of its global information system. In a virtual enterprise, organizations are exchanging information using Internet facilities such as e-mail. Some facilities such as message-passing do not fully support security features. Furthermore, unauthorized users can access the information system taking it to an inconsistent state. Therefore, the main problem in these organizations is to maintain the integrity and the consistency of their information systems. We present the application of SET (Secure Electronic Transaction) and RBAC (Role-Based Access Control) to guarantee the consistency of information system within a virtual enterprise. We use human resource planning in a virtual environment as a guideline in the description of our models. The description is based on the Raise Specification Language (RSL).
