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.

Abstract translation: 在实现中，公开了一种用于位置保证的计算机实现的方法。 该方法可以包括通过在移动计算设备上执行的应用程序从服务器接收电子令牌，其中电子令牌包括使用密码签名算法签名的时间戳; 通过应用将电子令牌提供给被动计算标签，其中电子令牌由被动计算标签签署; 由应用程序接收由被动计算标签签署的电子令牌; 并通过应用程序提供与服务器签署的电子令牌。
