Abstract
In implementations, a computer-implemented method for location assurance is disclosed. The method can include receiving, by an application executing on a mobile computing device, an electronic token from a server, wherein the electronic token comprises a timestamp signed using a cryptographic signing algorithm; providing, by the application, the electronic token to a passive computational tag, wherein the electronic token is countersigned by the passive computational tag; receiving, by the application, the electronic token that was countersigned by the passive computational tag; and providing, by the application, the electronic token that was countersigned to the server.
