Lifty is a DSL for data-centric applications that manipulate sensitive data. In Lifty, the programmer implements the core functionality of the application as if all the data were publicly visible, and then separately provides a policy module that describes the data and the associated policies. The Lifty compiler automatically injects policy-enforcing code throughout the application, and guarantees that the resulting code satisfies all the policies.
