AI Technical Summary

Technical Problem

Existing electronic devices face challenges in miniaturizing biometric sensors for user authentication while maintaining functionality, particularly when incorporating sensors like iris, fingerprint, or face recognition, due to their size and weight constraints.

Method used

An electronic device, such as a smart ring or stylus pen, uses sensors to identify gestures and perform user authentication by acquiring feature data through sensors, comparing it to reference data within a security element, and transmitting authentication signals via communication circuits, allowing for miniaturization and efficient user verification.

Benefits of technology

This approach enables secure and efficient user authentication with reduced device size and power consumption, enhancing the usability and convenience of payment and other services by leveraging gesture recognition technology.

Abstract

The electronic device may include a memory for storing instructions, a communication circuit, one or more sensors, and at least one processor. The at least one processor may cause the electronic device to identify a first gesture through one or more sensors while a communication link between the electronic device and an external electronic device is established using the communication circuit, execute a mode for performing user authentication based on a determination that the first gesture is a defined gesture, acquire data through one or more sensors that is expressed by a part of the user associated with the electronic device and represents a characteristic of a second gesture following the first gesture, and transmit a signal indicating the success of user authentication to the external electronic device through the communication link using the communication circuit based on a determination that the difference between the reference data representing a characteristic of the reference gesture and the data is within a reference range.
