Abstract

One embodiment provides a method, including: identifying a biometric pattern present in a wireless signal associated with an information handling device; determining, using a processor, whether the biometric pattern corresponds to an authorized biometric pattern; and authenticating, responsive to determining that the biometric pattern corresponds to the authorized biometric pattern, a user of the information handling device. Other aspects are described and claimed.

First claim

What is claimed is:

1. A method, comprising:
identifying a biometric pattern present in a wireless signal associated with an information handling device, wherein the biometric pattern corresponds to channel state information amplitude of at least one subcarrier of the wireless signal identified from channel state information of the wireless signal;
determining, using a processor, whether the biometric pattern corresponds to an authorized biometric pattern, wherein the determining comprises filtering, via signal processing, environmental radio interference out of the channel state information, utilizing a subcarrier selector to identify a most sensitive subcarrier from the at least one subcarrier in the filtered channel state information, and extracting, from the most sensitive subcarrier, at least one feature; and
authenticating, responsive to determining that the biometric pattern corresponds to the authorized biometric pattern, a user of the information handling device.

2. The method of claim 1 , wherein the biometric pattern is influenced by a biometric characteristic associated with the user.

3. The method of claim 2 , wherein the biometric characteristic is selected from the group consisting of: breathing data, ambulatory data, and heartbeat data.

4. The method of claim 1 , wherein the identifying comprises:
continuously collecting the channel state information of the wireless signal; and
identifying, within the channel state information, the channel state information amplitude of the at least one subcarrier.

5. The method of claim 1 , wherein the determining comprises determining without utilization of a sensor.

6. The method of claim 1 , wherein the authorized biometric pattern is contained in a user profile associated with the user.

7. The method of claim 1 , wherein the authorized biometric pattern is associated with an authorized user.

8. An information handling device, comprising:
a processor;
a memory device that stores instructions executable by the processor to:
identify a biometric pattern present in a wireless signal associated with the information handling device, wherein the biometric pattern corresponds to channel state information amplitude of at least one subcarrier of the wireless signal identified from channel state information of the wireless signal;
determine whether the biometric pattern corresponds to an authorized biometric pattern, wherein the determining comprises filtering, via signal processing, environmental radio interference out of the channel state information, utilizing a subcarrier selector to identify a most sensitive subcarrier from the at least one subcarrier in the filtered channel state information, and extracting, from the most sensitive subcarrier, at least one feature; and
authenticate, responsive to determining that the biometric pattern corresponds to the authorized biometric pattern, a user of the information handling device.

9. The information handling device of claim 8 , wherein the biometric pattern is influenced by a biometric characteristic associated with the user.

10. The information handling device of claim 9 , wherein the biometric characteristic is selected from the group consisting of: breathing data, ambulatory data, and heartbeat data.

11. The information handling device of claim 8 , wherein the instructions executable by the processor to identify comprise instructions executable by the processor to:
continuously collect the channel state information of the wireless signal; and
identify, within the channel state information, the channel state information amplitude of the at least one subcarrier.

12. The information handling device of claim 8 , wherein the instructions executable by the processor to determine comprise instructions executable by the processor to determine without utilization of a sensor.

13. The information handling device of claim 8 , wherein the authorized biometric pattern is contained in a user profile associated with the user.

14. A product, comprising:
a storage device that stores code, the code being executable by a processor and comprising:
code that identifies a biometric pattern present in a wireless signal associated with an information handling device, wherein the biometric pattern corresponds to channel state information amplitude of at least one subcarrier of the wireless signal identified from channel state information of the wireless signal;
code that determines whether the biometric pattern corresponds to an authorized biometric pattern, wherein the determining comprises filtering, via signal processing, environmental radio interference out of the channel state information, utilizing a subcarrier selector to identify a most sensitive subcarrier from the at least one subcarrier in the filtered channel state information, and extracting, from the most sensitive subcarrier, at least one feature; and
code that authenticates, responsive to determining that the biometric pattern corresponds to the authorized biometric pattern, a user of the information handling device.
