Abstract

Disclosed is a security monitoring method in a Bluetooth device, the method including detecting transmission or reception of a predetermined monitor-target message when a user device is in a connection-available or authentication-available scan mode enabling a user to recognize the occurrence of the monitor-target message; and recording log information about the monitor-target message. Therefore, a user equipment monitors authentication and connection requests by using the Bluetooth connection feature, so that the user can recognize a connection set up and release between devices by using log record although the connection set up and release is generated without user'"'"'s knowledge. In addition, since the user equipment notifies the user of authentication and connection set up (e.g., by using a beep, a vibration or other alerting means), the user can influence the connection set up and release.

Claims

1. A security monitoring method in a Bluetooth device, the method comprising of the steps of:

a) detecting a transmission or a reception of a predetermined monitor-target message when a user device is in one of a connection-available or an authentication-available scan mode;

b) enabling a user to recognize an occurrence of the monitor-target message; and

c) recording log information about the monitor-target message.

2. The method as claimed in claim 1, wherein the monitor-target message is an inquiry request message received for detection in an inquiry scan state and a page scan state.

3. The method as claimed in claim 1, wherein the monitor-target message is a paging request message received for connection in the page scan state.

4. The method as claimed in claim 1, wherein the monitor-target message is a PIN code request message received for authentication in the page scan state.

5. The method as claimed in claim 1, wherein, in step b), a user of the user device is notified of the occurrence of the monitor-target message using at least one of by an audible tone, a vibration and a visual display on a display window.

6. The method as claimed in claim 1, wherein the log information includes a time corresponding to the time of the detecting the transmission or the reception of the monitor-target message, information about a counterpart Bluetooth device, and a record of a progress procedure according to the monitor-target message.

7. The method as claimed in claim 1, wherein the monitor-target message includes an inquiry request and response message, a page request message, a paging response message, a PIN (Personal Identification Number) code request and response message, a link key exchange message, a reception and transmission of data information message, and a message relating to connection set up and release.

8. The method as claimed in claim 6, further comprising displaying on a display window a procedure for authentication of and connection with a counterpart device according to the monitor-target message.
