Information sharing between businesses and government agencies is of vital importance, yet business are often reluctant to share information, e.g. as it might be misused. Taking this into account is however often overlooked in the design of software architectures. In this research we apply a design science approach to develop an software architecture that is acceptable by businesses. From a case study we derive the requirements an architecture should meet in order to contribute to increasing willingness to share information. In this paper the architecture is developed and evaluated according to the requirements. We recommend the use of different types of business rules that provide businesses with control over their data, in combination with encryption and decryption of data to provide access to parts of the data within an organization.
