Security policies are important for protecting digitalized information, control resource access and maintain secure data storage. This work presents the development of a policy language to transparently incorporate aggregate programming and privacy models for distributed data. We use tuple spaces as a convenient abstraction for storage and coordination. The language has been designed to accommodate well-known models such as k-anonymity and

$$(\varepsilon ,\delta )$$ (ε,δ)-differential privacy, as well as to provide generic user-defined policies. The formal semantics of the policy language and its enforcement mechanism is presented in a manner that abstracts away from a specific tuple space coordination language. To showcase our approach, an open-source software library has been developed in the Go programming language and applied to a typical coordination pattern used in aggregate programming applications.
