Abstract:
1. A method comprising: querying, by a first computing device, a server device; subsequent and responsive to querying the server device, receiving, by the first computing device, instructions from the server device to re-query the server device at a first specified time; responsive to receiving instructions to re-query and after the server device receives a query from a second computing device, re-querying, by the first computing device, the server device at the first specified time; subsequent and responsive to re-querying the server device, receiving, by the first computing device, an address associated with the second computing device and instructions from the server device to connect to the second computing device at a second specified time; responsive to receiving instructions from the server device to connect to the second computing device, determining, by the first computing device, whether the second computing device is within a specified physical proximity to the first computing device by attempting to connect, by the first computing device, with the second computing device at the second specified time based at least in part on the address associated with the second computing device; responsive to the first computing device successfully connecting with the second device at the second specified time, determining, by the first computing device, that the second computing device is within the specified physical proximity to the first computing device; and responsive to the first computing device not being able to successfully connect with the second device at the second specified, determining, by the first computing device, that the second computing device is not within the specified physical proximity to the first computing device.
