Abstract
Provided is an operating method of a wearable device, the method including setting a threshold voltage when there is not a physical contact of an outsider, measuring an envelope voltage while performing a data communication, determining whether to be the physical contact with the outsider by comparing the threshold voltage with the envelope voltage, and stopping the data communication, when there is the physical contact with the outsider.
Claims20
A data security method of a wearable device attached to a human body of a user, comprising:
- setting a threshold voltage when there is no physical contact between the user and an outsider;
- measuring an envelope voltage while performing data communication;
- determining whether there is the physical contact between the user and the outsider by comparing the threshold voltage with the envelope voltage;
- and
- stopping the data communication when there is a physical contact between the user and the outsider,
- wherein the threshold voltage is set using an envelope voltage measured for a predetermined period of time when there is no physical contact between the user and the outsider.
A wearable device attached to a human body of a user, comprising:
- a signal receiver configured to receive a signal through the human body of the user;
- an envelope detector configured to measure an envelope voltage of the received signal;
- and
- a voltage comparator configured to compare a threshold voltage with the envelope voltage in order to determine whether there is a physical contact between the user and an outsider,
- wherein the threshold voltage is set using an envelope voltage measured for a predetermined period of time when there is no physical contact between the user and the outsider, and
- wherein, when the threshold voltage is greater than the envelope voltage of the received signal, data communication corresponding to the received signal is stopped or a communication holding signal is transmitted to a signal transmitter.
A data receiving method of a wearable device attached to a human body of a user, the data receiving method comprising:
- receiving a signal via the human body for data communication;
- filtering and amplifying the received signal;
- measuring an envelope voltage of the filtered and amplified signal;
- comparing a threshold voltage with the measured envelope voltage to determine whether there is a physical contact between the user and an outsider;
- and
- blocking the data communication when the measured envelope voltage is less than the threshold voltage,
- wherein the data receiving method further comprises setting the threshold voltage using an envelope voltage measured for a predetermined period of time when the data communication is proceeded and when there is no physical contact between the user and the outsider.
