Abstract: Provided herein is a method, apparatus, and system for identifying a health status of an individual, by using a health challenge of the individual to gather vital sign information to generate a health status of the individual. Method for identifying health status include: generating a non-persistent identifier for a user; receiving an indication of an initiation of a health challenge for the user associated with the non-persistent identifier; receiving, responsive to the health challenge, an indication of at least one vital sign of the user; determining, from the at least one vital sign, a health status of the user; and providing an indication of the health status of the user and the associated non-persistent identifier, where the health status includes a binary indication of health of the user, and where the health status is used to permit or deny a service to the user.
