Claim 15:
16. A system, comprising:
at least one processor comprising a trusted execution environment (TEE); and
memory storing instructions that, when executed by the TEE, cause the TEE to perform operations comprising:
receiving, from a downstream device communicatively coupled to the system, a downstream passport indicating a geographic region in which the downstream device is located;
generating an aggregate passport based on the geographic region in which the downstream device is located and the geographic region in which the system is located;
receiving, via an application programming interface (API), a request from a user device;
generating, based on the request, a query for data associated with fulfilling the request, the data comprising information related to at least one identified and/or identifiable person;
transmitting, to a data controller subjected to a more stringent data privacy rule than the system, the query;
transmitting, to the data controller, an indication of a geographic region in which the system is located by transmitting the aggregate passport to the data controller;
receiving, from the data controller, a portion of the data associated with fulfilling the request, the portion of the data omitting the information related to at least one identified and/or identifiable person;
generating a response based on the portion of the data; and
transmitting, via the API, the response to the user device.
