Methods, apparatus, servers, and systems for human identification based on human radio biometric information

A method, implemented on a machine including at least a receiver, a processor and a memory communicatively coupled with the processor for human identification, comprising:

• receiving at least one wireless signal from a multipath channel that is impacted by a person to be identified;
• extracting CSI from the at least one wireless signal, wherein the CSI represents channel properties of the multipath channel itself;
• obtaining radio biometric information based on the CSI, wherein the radio biometric information represents how the at least one wireless signal was impacted by at least part of a body of the person;
• and
• determining an identity of the person based on the radio biometric information.

An apparatus (1701) for human identification, comprising:

• a plurality of receivers (1722) each of which is configured for receiving at least one wireless signal from a multipath channel that is impacted by a person to be identified;
• a processor (1730);
• and
• a memory communicatively coupled with the processor, wherein the processor is configured for:
• extracting, regarding each of the plurality of receivers, CSI from the at least one wireless signal, wherein the CSI represents channel properties of the multipath channel itself,
• obtaining, from each of the plurality of receivers, radio biometric information based on the CSI, wherein the radio biometric information represents how the at least one wireless signal was impacted by at least part of a body of the person,
• combining the radio biometric information obtained from the plurality of receivers to generate combined radio biometric information, and
• determining an identity of the person based on the combined radio biometric information.
