Abstract: A complicated software system can be decomposed into subsystems for different teams to develop, in which the teams may distribute geographically and need not belong to the same company. Many issues should be solved when developing software systems in this manner. For example, developing a software system that can prevent information leakage during the execution of the systems is an essential issue. The prevention can be achieved by embedding an information flow control model in the system. Since the teams that develop a software system need not belong to the same company, different teams may be familiar with different information flow control models. To embed information flow control model in a complicated software system decomposed into subsystems, the following approaches can be used: (a) embedding the same information flow control model in every subsystem and (b) allowing different information flow control models to be embedded in different subsystems. If the first approach is used, software developers unfamiliar with the assigned model may be unwilling to use the model. Moreover, if a software system is developed through reuse, the reused components may be embedded with different information flow control models. This causes difficulty in the reuse. We suggest that the second approach should be used and propose a model IFCMC (information flow control model coordinator) to coordinate heterogeneous information flow control models. This study proposes IFCMC and its evaluation.
