Abstract

A mobile terminal including a transceiver configured to transmit and receive signals to and from another mobile terminal, a security parameter module configured to set a security parameter in data to be transmitted to the another mobile terminal and to detect whether or not the security parameter is set in data received from the another mobile terminal, and a checking module configured to compare information related to the mobile terminal and the another mobile.

Claims

1. A mobile terminal, comprising:

a transceiver configured to transmit and receive signals to and from another mobile terminal;

a security parameter module configured to set a security parameter in data to be transmitted to said another mobile terminal and to detect whether or not the security parameter is set in data received from said another mobile terminal; and

a checking module configured to compare information related to the mobile terminal and said another mobile.

2. The mobile terminal of claim 1, wherein when the mobile terminal receives data from the another mobile terminal and the security parameter module detects the security parameter is set in the received data, the checking module determines if an address corresponding to the another mobile terminal is included in an address list of the mobile terminal.

3. The mobile terminal of claim 2, wherein when the checking module determines the address corresponding to the another mobile terminal is included in the address list of the mobile terminal, the received data is stored in a memory of the mobile terminal and a user using the mobile terminal is notified about the received data.

4. The mobile terminal of claim 2, wherein when the checking module determines the address corresponding to the another mobile terminal is not included in the address list of the mobile terminal, the received data is not stored in a memory of the mobile terminal.

5. The mobile terminal of claim 1, wherein when the mobile terminal transmits data to the another mobile terminal, the security parameter module determines whether or not a security option is turned on, and sets the security parameter in the data to be transmitted when the security option is on and does not set the security parameter in the data to be transmitted when the security option is not on.

6. The mobile terminal of claim 5, wherein after the security parameter module sets the security parameter in the data to be transmitted, the checking module determines if an address corresponding to the another mobile terminal is included in an address list of the mobile terminal.

7. The mobile terminal of claim 6, wherein when the checking module determines the address corresponding to the another mobile terminal is included in the address list of the mobile terminal, the data is transmitted to the another mobile terminal.

8. The mobile terminal of claim 6, wherein when the checking module determines the address corresponding to the another mobile terminal is not included in the address list of the mobile terminal, the data is not transmitted to the another mobile terminal.

9. The mobile terminal of claim 1, further comprising:

an authentication module configured to request authentication from the mobile terminal or the another mobile terminal.

10. The mobile terminal of claim 9, wherein when the mobile terminal receives data from the another mobile terminal and the security parameter module detects the security parameter is set in the received data, the authentication module requests authentication from the mobile terminal that it is ok to receive the data.

11. The mobile terminal of claim 9, wherein when the mobile terminal transmits data to the another mobile terminal and the security parameter module detects the security parameter is set in the data to be transmitted, the authentication module requests authentication from the another mobile terminal that it is ok to transmit the data to the another mobile terminal.

12. The mobile terminal of claim 1, wherein when the mobile terminal transmits data to the another mobile terminal and the security parameter module determines the security parameter in the data to be transmitted is not set, the checking module certifies profiles of the another mobile terminal and the mobile terminal to determine if the security parameter should be set.

13. The mobile terminal of claim 9, further comprising:

a control processor configured to control the transceiver, the security parameter module, the checking module and the authenticating module.

14. A mobile terminal method, comprising:

transmitting and receiving, via a first mobile terminal, signals to and from a second mobile terminal;

setting a security parameter in data to be transmitted to said second mobile terminal and detecting whether or not the security parameter is set in data received from said second mobile terminal; and

comparing information related to the first mobile terminal and the second mobile.

15. The mobile terminal method of claim 14, wherein when the first mobile terminal receives data from the second mobile terminal and the detecting step detects the security parameter is set in the received data, the comparing step determines if an address corresponding to the second mobile terminal is included in an address list of the first mobile terminal.

16. The mobile terminal method of claim 15, wherein when the comparing step determines the address corresponding to the second mobile terminal is included in the address list of the first mobile terminal, the received data is stored in a memory of the first mobile terminal and a user using the first mobile terminal is notified about the received data.

17. The mobile terminal method of claim 15, wherein when the comparing step determines the address corresponding to the second mobile terminal is not included in the address list of the first mobile terminal, the received data is not stored in a memory of the first mobile terminal.

18. The mobile terminal method of claim 14, wherein when the first mobile terminal transmits data to the second mobile terminal, the setting step determines whether or not a security option is turned on, and sets the security parameter in the data to be transmitted when the security option is on and does not set the security parameter in the data to be transmitted when the security option is not on.

19. The mobile terminal method of claim 18, wherein after the setting step sets the security parameter in the data to be transmitted, the comparing step determines if an address corresponding to the second mobile terminal is included in an address list of the first mobile terminal.

20. The mobile terminal method of claim 19, wherein when the comparing step determines the address corresponding to the second mobile terminal is included in the address list of the first mobile terminal, the data is transmitted to the second mobile terminal.

21. The mobile terminal method of claim 19, wherein when the comparing step determines the address corresponding to the second mobile terminal is not included in the address list of the first mobile terminal, the data is not transmitted to the second mobile terminal.

22. The mobile terminal method of claim 14, further comprising:

requesting authentication from the either the first or second mobile terminals.

23. The mobile terminal method of claim 22, wherein when the first mobile terminal receives data from the second mobile terminal and the detecting step detects the security parameter is set in the received data, the requesting step requests authentication from the first mobile terminal that it is ok to receive the data.

24. The mobile terminal method of claim 22, wherein when the first mobile terminal transmits data to the second mobile terminal and the detecting step detects the security parameter is set in the data to be transmitted, the requesting step requests authentication from the second mobile terminal that it is ok to transmit the data to the second mobile terminal.

25. The mobile terminal method of claim 14, wherein when the first mobile terminal transmits data to the second mobile terminal and the detecting step determines the security parameter in the data to be transmitted is not set, the comparing step certifies profiles of the first mobile terminal and the second mobile terminal to determine if the security parameter should be set.
