Abstract
A privacy control system is described herein for controlling dissemination of private information by a program. The privacy control system operates by performing static analysis to determine at least one flow within the program of private information, from a source to a sink. The static analysis is particularly configured to identify two types of flow, including: (a) an unvetted flow of untampered private information from the source to the sink; and (b) a flow of tampered private information from the source to the sink, whether vetted or unvetted. The privacy control system then prompts the user to provide a privacy control decision regarding the flow. The privacy control decision governs whether actual data or anonymized data is provided to the sink, or whether the program is terminated. A runtime system then runs the program in accordance with the privacy control decision.
