Abstract
A method for a system includes receiving with a first transceiver of a first smart device, an advertisement signal from a stationary beacon, outputting with the first transceiver of the first smart device, a first ephemeral ID that is not permanently associated with the first smart device, to the stationary beacon, receiving with the first transceiver of the first smart device, a beacon identifier from a stationary beacon, outputting with a second transceiver of the first smart device, the first ephemeral ID, a first user identifier and the beacon identifier to an authentication service, storing in an association log in the authentication service, the first ephemeral ID, the first user identifier and the beacon identifier, and storing in a beacon log in the authentication service, a log of the stationary beacon including the first ephemeral ID.
