AI Technical Summary

Technical Problem

Existing user authentication methods for personalized electronic devices, such as smartphones, often lack convenience and efficiency, especially for high-security applications, and there is a need for a more innovative and secure biometric authentication method.

Method used

Utilizing earphones equipped with a Photoplethysmography (PPG) sensor to detect user bio-responses, including vibrations and blood flow changes in the external auditory canal, to authenticate users based on their biometric data, which includes generating a feature vector and comparing it with a pre-stored user profile.

Benefits of technology

Provides a convenient and efficient user authentication method that enhances security by continuously or periodically authenticating users using earphones, allowing seamless access to applications and services without additional authentication steps.
