Abstract
A secure repository receives and stores user data, and shares the user data with trusted client devices. The user data may be shared individually or as part of bundled data relating to multiple users, but in either case, the secure repository associates specific data with specific users. This association is maintained by the trusted client devices, even after the data is altered by processing on the client device. If a user requests a purge of their data, the system deletes and/or disables that data on both the repository and the client devices, as well as deleting and/or disabling processed data derived from that user's data, unless a determination has been made that the processed data no longer contains confidential information.
