Abstract: A system and method for generating a risk score for an observer device based on the wireless signals that are emitted from one or more wireless devices is provided. The system and method includes receiving, by an analytic server, a request for tracing data associated with a first device identifier of a first observer device; generating, by the analytic server responsive to receiving the request, tracing data including a second identifier of a second observer device and a risk score indicative of a degree of association between the first observer device and the second observer device; and transmitting, by the analytic server, the tracing data to a human resource (HR) server associated with an organization, wherein the tracing data causes the HR server to notify the second observer device.

Abstract: Techniques for performing automatic contact tracing using a fleet of mobile electronic devices are provided. By collecting and storing signal data detected by the fleet of devices, the system generates a historical record of timestamped signal data from which interpersonal interactions may be inferred. The system may retrieve information from the stored historical record to determine what users were in contact with a target user during a target time period. The determination may be based on which other devices were proximate to the target device, at what time those other devices were proximate, how close those other devices were, and/or the amount of time for which those devices were proximate. The system may applying one or more algorithms (e.g., a “proximity score” calculation) to the stored record in order quantify and/or characterize a risk for users of devices that were proximate to the target device.
