A variety of valuable mobile utility apps heavily rely on collecting a user’s app usage data to carry out their promised utilities and enhance user experiences. A part of such app usage data often contains security-sensitive information. Thus, an important and challenging issue arises: how to balance between the user’s privacy and the utility app’s utility functionality. Towards addressing the issue, we propose a new privacy framework that combines techniques of runtime sensitive-information detection, utility-impact analysis, privacy-policy compliance checking, and balanced data anonymization to enable a third-party app to determine what original values to keep in sanitized data in order to deliver a desirable level of utility efficacy.
