Abstract: Disclosed is a system that tracks website usage without compromising user privacy. The system aggregates website usage data of multiple users across multiple websites. Website usage data is aggregated in a way that preserves each individual user's privacy. Specifically, information relevant to a particular user may be obtained from the aggregated information without exposing what was actually collected from that user. In some configurations, user-specific website usage data is aggregated using trusted execution environment computing hardware. This ensures that privacy is preserved while user-specific data is transferred to and processed by the system. The trusted execution environment applies differential privacy techniques to ensure that use of the aggregated information does not reveal actual information about a user's website usage history. In this way, privacy is maintained while still enabling many of the scenarios that would otherwise rely on third-party cookies.

Abstract: Systems and methods for determining a remaining useful life (RUL) of a component of an engine system are provided. A method includes: receiving component data comprising sensor data corresponding to a component and engine data; pre-processing the component data by removing a first set of sensor data values that correspond to a first set of engine data values of the engine data; aggregating the pre-processed component data by grouping a second set of sensor values of the sensor data; determining a RUL for the component based on a RUL model that correlates at least a portion of the aggregated data to RUL values; adjusting the RUL based on at least one of detecting a service event or determining that one or more sensor data values of the sensor data are outside a predetermined range of values; and providing the RUL to a user device.
