Abstract
Devices, systems and methods are disclosed for determining an electromagnetic signature for authenticating a device, a user, and/or a location. In exemplary embodiments, a magnetometer captures an electromagnetic signature which is then compared with one or more authorized electromagnetic signatures. If the electromagnetic signature matches an authorized electromagnetic signature, then access is granted. The magnetometer is integrated into a communication device having a processor and a logic. The magnetometer captures an electromagnetic signature of a surrounding environment and detects motion of the communication device through the captured electromagnetic signature. The logic on the communication device locks or unlocks features of the device based upon the captured electromagnetic signature. In further embodiments of the subject disclosure, the magnetometer is in communication with a server which authenticates a user or communication device to provide access to a remote location.
