Abstract
An apparatus including interface circuitry configured to read, from a sensor, event data indicating an event detected by the sensor and identification data indicating a first identifier (ID) of a user involved in the event. The first interface circuitry is further configured to generate a data stream comprising at least the event data and the identification data. Additionally, the apparatus includes processing circuitry configured to generate an updated data stream based on the data stream by updating the first ID to a second ID using a deterministic update function, and by adding noise to at least the event data. The processing circuitry is further configured to determine whether sufficient privacy budget is left for the updated data stream, and, if so, generate encrypted data by encrypting the updated data stream. The apparatus includes second interface circuitry configured to output the encrypted data for transmission to an external data aggregator.
