Abstract
An electronic device having user identification function and a user authentication method are provided. The electronic devices comprises: a body; a user identification unit that detects a body signal of the user and processes authentication of the user; an in-use detection unit that detects the body signal of the user and checks whether the user uses the electronic device; and a processor that authenticates the user according to detection signals of the user identification unit and the in-use detection unit.
Claims12
An electronic device for use with a user, the electronic device comprising:
- a band comprising a first end and a second end, the band configured to secure the electronic device on the user when the first end is coupled to the second end;
- a user identification device configured to:
- detect a body signal of the user, and
- generate an authentication signal of the user to be transmitted from the electronic device to an external device;
- an in-use detection device configured to determine whether the user uses the electronic device, the in-use detection device comprising a coupling detection sensor and a heart rate monitor (HRM) sensor;
- at least one processor configured to:
- authenticate the user according to the body signal detected by the user identification device,
- transmit the authentication signal from the electronic device to the external device,
- based on the user being authenticated by the user identification device, determine the electronic device is being worn by detecting that the first end of the band is coupled to the second end of the band and the HRM sensor detecting that the user wears the electronic device,
- based on the determination that the electronic device is being worn, determine that the band has not been cut, and
- based on the determination that the while the electronic device is being worn the band has not been cut, operate an application on the electronic device in association with the authentication signal;
- and
- a memory configured to store authentication information of the user authenticated by the at least one processor,
- wherein the at least one processor is further configured to eliminate at least a portion of the authentication information of the user stored in the memory in response to the coupling detection sensor detecting that the first end of the band is not coupled to the second end of the band or the HRM sensor detecting that the user is not wearing the electronic device.

A user authentication method for use with an electronic device having a band, the method comprising:
- registering an electrocardiogram (ECG) pattern of a user resulting in a registered ECG pattern;
- sensing an ECG pattern of the user;
- comparing the registered ECG pattern and the ECG pattern of the user sensed, and
- identifying the user;
- if the registered ECG pattern coincides with the ECG pattern of the user sensed based on the identification, authenticating the user including generating an authentication signal of the user and storing authentication information;
- checking a wearing state of a body by a coupling detection sensor detecting that a first end of the band is coupled to a second end of the band and a heart rate monitor (HRM) sensor detecting that the user wears the electronic device;
- based on the user being authenticated by the user identification device, determining the electronic device is being worn by detecting that the first end of the band is coupled to the second end of the band and the HRM sensor detecting that the user wears the electronic device;
- based on the determination that the electronic device is being worn, determine that the band has not been cut;
- and
- based on the determination that the while the electronic device is being worn the band has not been cut, transmitting the authentication signal from the electronic device to an external device and allowing an application on the electronic device to be operable in association with the authentication signal;
- and
- eliminating at least a portion of the authentication information stored in response to the coupling detection sensor detecting that the first end of the band is not coupled to the second end of the band or the HRM sensor detecting that the user is not wearing the electronic device.
