Abstract: Techniques for secure mobile device recognition are disclosed. An IOT edge device determines, based on a network message received at the IOT edge device, that a mobile device is not recognized. The IOT edge device transmits a token request to the mobile device. In response, the IOT edge device receives an encrypted token from the mobile device. The IOT edge device transmits the encrypted token to a server. The server is configured to determine an identifier corresponding with the mobile device, based on the encrypted token. A recognition task is initiated for the mobile device, based on the determined identifier.

Abstract: Systems, methods and articles of manufacture to perform an operation comprising receiving, from one of a plurality of stations, a message which includes at least a random number and a first hash value of the random number concatenated with a first key, comparing the first hash value to one or more second hash values, wherein each second hash value is generated by hashing the random number concatenated with one of a plurality of second keys and wherein each second key corresponds to a registered device of a device identification system, upon determining the first hash value matches one of the second hash values, determining an identity of the mobile device based on the corresponding second key, and based on the location of the station which sent the message, assigning a location to the mobile device.

Abstract: Disclosed herein are various systems and methods for transmitting information using modulated magnetic fields. A system comprises a transmitter having a first magnetic field source for transmitting a first modulated magnetic field to a receiver for decoding and a field controller coupled to the first magnetic field source for controlling the first modulated magnetic field. The system can further include a receiver having a first magnetometer configured to detect the first modulated magnetic field produced by the first magnetic field source and a decoder coupled to the first magnetometer for interpreting the first modulated magnetic field.
