Ancile provides an interface for principals to authorize data import from a data provider and to specify policies to be associated with all data about a an individual received by an application from that data provider...
Ancile implements a reactive mechanism that updates the associated policy when a data value is used and that synthesizes policies for any derived data values. To support extensible development of location-based services by third parties, Ancile offers a Python library of commands that application developers can use to write programs for handling location data or any other type of sensitive data. It as well supports wrapping any third-party library to be enforced by policies. Ancile executes these programs on behalf of the applications and enforces that the data are only processed in compliance with their associated policies.
