Abstract: Systems and methods are provided for context-module-based personal data protection. Systems and methods provide a user device's user interface with two or more context modules associated with a respective set of applications. Upon receiving a user input to launch an application, the application is executed using data permissions associated with the context from which the user launches the application. Permission for application requests for data are determined based on the data permissions associated with the launch context. For some embodiments, the context may be selected automatically based on sensor data or a user device's context or location. For some embodiments, the context may be changed between two contexts. Such context changes may occur without changing user accounts. For some embodiments, a third user may execute a third application using the data permissions associated with the first context module.

Abstract: Disclosed herein are systems and methods for protecting user privacy in networked data collection. One embodiment takes the form of a method that includes obtaining a user-data request that is associated with a requesting party. The method also includes preparing a first candidate response to the user-data request, where the first candidate response is based at least in part on data that is associated with a first user. The method also includes receiving additional candidate responses that are respectively based on data that is respectively associated with a plurality of additional users. The method also includes determining a privacy level of the first candidate response based at least in part on the received plurality of additional candidate responses. The method also includes determining that the privacy level exceeds a privacy threshold, and responsively sending, to the requesting party, a user-data response associated with the user-data request.

Abstract: Systems and methods for use in a secure personal data marketplace are disclosed. In accordance with one method, a request for processed user data from a requesting party is received at an electronic marketplace. The request for the processed user data is published from the electronic marketplace to a plurality of responding agents. The plurality of responding agents determine whether one or more of the users will be a user participant. The responding agents send the user information for the user participants to the electronic marketplace, where the user information is processed in a trusted environment to generate the processed user data requested by the requesting party. The processed user data is sent from the electronic marketplace to the requesting party, and the user information and processed user data is deleted from the electronic marketplace once the processed user data has been sent to the requesting party.
