Method for verifying user identity using magnetic field changes

A recently granted patent (Publication Number: US11777928B2) describes a method and system for verifying a user at a kiosk device. The method involves capturing information about a user attempting to access the kiosk device using one or more sensors. The kiosk device then changes parameters of a magnetic field generated by the device to encode identification information into a magnetic signal. This magnetic signal is detected by a mobile device associated with the user. The magnetic signal consists of frequency shift keying (FSK) modulated magnetic waves that can be decoded by the receiver in the mobile device using aliasing. The frequencies used in the FSK modulated magnetic waves are higher than the sampling rate of the receiver.
The kiosk device receives second information from one or more servers, which identifies the user of the mobile device that detects the changes in the magnetic field parameters. Based on the first and second information, the kiosk device verifies whether the user attempting to access the kiosk device is the user of the mobile device. If the verification is successful, the user is granted access to the kiosk device.
The method also includes additional features such as changing the parameters of the magnetic field by an electric circuit coupled to a conductor around a magnetic core of the kiosk device. The parameters can include the strength and direction of the magnetic field. The magnetic signal generated by the kiosk device can be binary data encoded using a modulation technique, with the binary data representing the identification information of the kiosk device. The binary data can be temporally encoded using signal bursts generated through a signal compression method. The magnetic signal can be a near-field magnetic induction (NFMI) signal.
The kiosk device can have various sensors, including image sensors or biometric sensors, to capture information about the user. The second information received from the servers can include an image of the user captured during an enrollment process.
Additionally, the system can include a beacon that communicates with the mobile device to awaken it when the user is within a threshold distance from the kiosk device.
Overall, this patent presents a method and system for verifying users at kiosk devices using magnetic signals and mobile devices, providing a secure and efficient access control mechanism.
