Abstract
A method for recognising a user whose body is capable of re-transmitting an electromagnetic signal in the form of an electromagnetic wave. The method is implemented on a transceiver device and includes the following steps on the device: transmitting an electromagnetic pulse signal; obtaining a re-transmitted signal when the user is in the vicinity of the device, the signal depending on the transmitted pulse signal; comparing the re-transmitted signal with at least one reference signal of the user; and recognising the user if the re-transmitted signal is close to the reference signal.
Claims20
A recognition method for recognizing a user, the method being implemented on a transceiver device and comprising the following acts implemented on the transceiver device:
- transmitting a pulsed electromagnetic signal;
- receiving, by a near field communication (NFC) antenna of the transceiver device in an intra-body communication (IBC) mode, a retransmitted signal retransmitted by his or her body when the user is in proximity to the transceiver device, said retransmitted signal being dependent on the pulsed electromagnetic signal transmitted;
- comparing the retransmitted signal with at least one reference signal of the user by measuring a distance between the retransmitted signal and the at least one reference signal;
- and
- recognizing the user if the measured distance is below a threshold.
A method for learning a signature of a user in order for him or her to be recognized, the method comprising the following acts implemented on the transceiver device:
- transmitting at least one pulsed electromagnetic signal;
- receiving, by a near field communication (NFC) antenna of the transceiver device in an intra-body communication (IBC) mode, at least one signal retransmitted by his or her body when the user is in proximity to the transceiver device, said at least one retransmitted signal being dependent on the pulsed electromagnetic signal transmitted;
- generating a reference signal, called a signature, as a function of said at least one retransmitted signal obtained;
- and
- saving said reference signal as signature of the user.
A device for recognizing a user, wherein the device comprises:
- a near field communication (NFC) antenna;
- and
- a processor configured to:
- transmit a pulsed electrical signal using the NFC antenna;
- receive, by the NFC antenna in an intra-body communication (IBC) mode, a retransmitted signal retransmitted by his or her body when the user is in proximity to the device, said retransmitted signal being dependent on the pulsed electromagnetic signal transmitted;
- compare the retransmitted signal with at least one reference signal of the user by measuring a distance between the retransmitted signal and the at least one reference signal;
- and
- recognize the user if the measured distance is below a threshold.
A mobile terminal or access control device comprising:
- a transceiver device comprising:
- a near field communication (NFC) antenna;
- and
- a processor configured to:
- transmit a pulsed electrical signal using the NFC antenna;
- receive, by the NFC antenna in an intra-body communication (IBC) mode, a retransmitted signal retransmitted by his or her body when the user is in proximity to the device, said retransmitted signal being dependent on the pulsed electromagnetic signal transmitted;
- and
- compare the retransmitted signal with a reference signal of the user by measuring a distance between the retransmitted signal and the reference signal;
- and
- recognize the user based on whether the measured distance is below a threshold.
A transceiver device for learning a signature of a user, wherein the transceiver device comprises:
- a near field communication (NFC) antenna;
- and
- a processor configured to:
- transmit a pulsed electrical signal using the NFC antenna;
- receive, by the NFC antenna in an intra-body communication (IBC) mode, a retransmitted signal retransmitted by his or her body when the user is in proximity to the transceiver device, said retransmitted signal being dependent on the pulsed electrical signal;
- and
- generate a reference signal, called signature, as a function of said retransmitted signal received and save said reference signal as signature of the user.
A mobile terminal or access control device for learning a signature of a user, said mobile terminal or access control device comprising:
- a transceiver device comprising:
- a near field communication (NFC) antenna;
- and
- a processor configured to:
- transmit a pulsed electrical signal using the NFC antenna;
- receive, by the NFC antenna in an intra-body communication (IBC) mode, a retransmitted signal retransmitted by his or her body when the user is in proximity to the transceiver device, said retransmitted signal being dependent on the pulsed electrical signal;
- and
- generate a reference signal, called signature, as a function of said retransmitted signal received and save said reference signal as signature of the user.
A non-transitory computer-readable medium comprising a computer program stored thereon comprising instructions for implementing method for recognizing a user, when the program is executed by a processor of a transceiver device, wherein the instructions configure the transceiver device to:
- transmit a pulsed electromagnetic signal;
- receive, by a near field communication (NFC) antenna of the transceiver device in an intra-body communication (IBC) mode, a retransmitted signal retransmitted by his or her body when the user is in proximity to the transceiver device, said retransmitted signal being dependent on the pulsed electromagnetic signal transmitted;
- compare the retransmitted signal with at least one reference signal of the user by measuring a distance between the retransmitted signal and the at least one reference signal;
- and
- recognize the user if the measured distance is below a threshold.
