AI Technical Summary

Technical Problem

Traditional identification methods such as keys or fingerprints require active user cooperation, which is cumbersome and inconvenient.

Method used

Identity can be identified by applying weak thermal pulses to local skin using sheet-like micro-heating elements in smart wearable devices and collecting the dynamic parameters of the temperature response curve, or by using the sound unit of smart headphones to output test excitation signals and collecting the acoustic characteristics of the ear canal response signal for identity verification.

Benefits of technology

It achieves a convenient identity recognition process that requires no active user cooperation, improves the accuracy and security of recognition, reduces system energy consumption, and does not affect the normal user experience.

Abstract

This invention discloses a user identity management method and related equipment based on a smart wearable device. The method includes: applying weak thermal pulses to local skin within a preset time window using sheet-like micro-heating elements positioned at corresponding locations on the inner side of a smart bracelet and the inner side of the wrist; continuously acquiring the local skin temperature output by a temperature sensor at a first sampling frequency throughout the heating and cooling process, constructing a temperature-time response curve; and performing normalization and fitting processing on the response curve to obtain at least one dynamic parameter characterizing the individual's local microcirculation and heat capacity characteristics for user identification. This method solves the problem that conventional identification methods such as keys or fingerprints require active user input, which is cumbersome and inconvenient.
