Abstract
A wearable device includes a communication unit that wirelessly communicates with a first external device; a motion sensor that senses the user's motion; and a control unit. The wearable device collects a first motion data generated by the user's motion and transmits the first motion data to the first external device, receives a first security level data and a second security level data from the first external device, and receives only the first security level data from the first external device when the wearable device is converted into a non-wearing state from a wearing state.
Claims21
A biometric authentication method of a wearable device, the method comprising:
- wirelessly communicating with a first external device;
- receiving a first request signal of the first external device, the first external device being in a first security state;
- determine whether the wearable device is in a wearing state after receiving the first request signal;
- transmitting non-wearing state information to the first external device when the wearable device is in the non-wearing state;
- collecting a first motion data generated by the user's motion through a motion sensor during a certain period of time or during collection of a certain amount of data when the wearable device is in a wearing state;
- transmitting the first motion data to the first external device;
- and
- receiving the first security level data and the second security level data from the first external device when the wearable device is in the wearing state, the first external device being in a second security state or a third security state;
- transmitting the non-wearing state information or the first state conversion information to the first external device when the wearable device is converted into the non-wearing state from the wearing state;
- and
- receiving only the first security level data from the first external device when the wearable device is in the non-wearing state, the first external device being in a fourth security or a fifth security state.
A wearable device comprising:
- a communication module that wirelessly communicates with a first external device;
- a motion sensor unit that detects a user's motion data;
- and
- a control unit,
- wherein the control unit receives a first request signal of the first external device when the first external device is in a first security state, determines whether the wearable device is in a wearing state to transmit the non-wearing state information to the first external device when the first external device is in the non-wearing state, collects the first motion data generated by the user's motion through the motion sensor during a certain period of time or during collection of a certain amount of data when the wearable device is in the wearing state, transmits the first motion data to the first external device, receives a first security level data and a second security level data from the first external device in the second security state or the third security state of the first external device when the wearable device is in the wearing state, transmits the non-wearing state information or the first state conversion information to the first external device when the wearable device is converted into the non-wearing state from the wearing state, and receives only the first security level data from the first external device in a fourth security state or a fifth security state of the portable electronic device when the wearable device is in the non-wearing state.
