Abstract

A method for authenticating an accessory apparatus by a host apparatus is provided. The method includes receiving authentication information from the accessory apparatus, comparing the received authentication information and pre-stored authentication information and performing authentication with respect to the accessory apparatus based on a result of the comparing, and, if the authentication is normally performed, performing a function corresponding to the accessory apparatus, and, if the authentication is not normally performed, transmitting corresponding information to an external server.

Claims

1. A method for authenticating an accessory apparatus by a host apparatus, the method comprising, at the host apparatus:

receiving authentication information from the accessory apparatus;

comparing the received authentication information and pre-stored authentication information and performing authentication with respect to the accessory apparatus according to a result of the comparing;

if the authentication is normally performed, performing a function corresponding to the accessory apparatus; and

if the authentication is not normally performed, transmitting corresponding information regarding the authentication not being normally performed to an external server.

2. The method as claimed in claim 1, further comprising, if the authentication is normally performed, transmitting preset setting information corresponding to the accessory apparatus to the accessory apparatus.

3. The method as claimed in claim 1, further comprising:

receiving apparatus information of the accessory apparatus;

comparing the received apparatus information and pre-stored lost article information and determining whether the accessory apparatus is a lost article based on a result of the comparing; and

if it is determined that the accessory apparatus is not the lost article, generating authentication information based on the apparatus information, storing the authentication information, and transmitting the authentication information to the accessory apparatus.

4. The method as claimed in claim 3, further comprising, if it is determined that the accessory apparatus is the lost article, transmitting the apparatus information and location information of the accessory apparatus which is determined to be the lost article to the external server.

5. The method as claimed in claim 3, wherein the apparatus information comprises at least one of information on a manufacturer of the accessory apparatus, information on a manufacturing date, information on a purchaser, information on a purchasing date, information on a purchase place, a serial number, and a model name.

6. The method as claimed in claim 3, wherein the lost article information is received through a broadcast signal or received through the external server and is updated at predetermined time intervals or based on a user command.

7. The method as claimed in claim 3, further comprising generating a control signal to disable operation of the accessory apparatus which is determined to be the lost article and transmitting the control signal to the accessory apparatus which is determined to be the lost article.

8. The method as claimed in claim 3, further comprising generating information indicating that the accessory apparatus is the lost article and transmitting the information to the accessory apparatus which is determined to be the lost article.

9. The method as claimed in claim 1, wherein the external server is a lost article management server which receives the corresponding information and determines whether the accessory apparatus is a lost article.

10. A method for controlling an accessory apparatus which performs authentication with a host apparatus, the method comprising:

transmitting authentication information to the host apparatus and requesting authentication; and

according to a result of the authentication, receiving preset setting information from the host apparatus and setting a function corresponding to the received setting information.

11. A host apparatus which performs authentication with an accessory apparatus, the host apparatus comprising:

a communication unit which receives authentication information from the accessory apparatus;

an authentication unit which compares the received authentication information and pre-stored authentication information and performs authentication with respect to the accessory apparatus based on a result of the comparison; and

a controller which, if the authentication is normally performed, performs a function corresponding to the accessory apparatus, and, if the authentication is not normally performed, transmits corresponding information regarding the authentication not being normally performed to an external server.

12. The host apparatus as claimed in claim 11, wherein, if the authentication is normally performed, the controller controls sets information corresponding to the accessory apparatus to be transmitted to the accessory apparatus.

13. The host apparatus as claimed in claim 11, wherein the communication unit receives apparatus information of the accessory apparatus,

wherein the authentication unit compares the received apparatus information and pre-stored lost article information and determines whether the accessory apparatus is a lost article based on a result of the comparison,

wherein, if the accessory apparatus is not determined to be the lost article, the controller generates authentication information based on the apparatus information, stores the authentication information, and transmits the authentication information to the accessory apparatus.

14. The host apparatus as claimed in claim 13, wherein, if the accessory apparatus is determined to be the lost article, the controller transmits the apparatus information and location information of the accessory apparatus which is determined to be the lost article.

15. The host apparatus as claimed in claim 13, wherein the apparatus information comprises at least one of information on a manufacturer of the accessory apparatus, information on a manufacturing date, information on a purchaser, information on a purchasing date, information on a purchase place, a serial number, and a model name.

16. The host apparatus as claimed in claim 13, wherein the lost article information is received through a broadcast signal or received through an external server, and is updated at predetermined time intervals or based on a user command.

17. The host apparatus as claimed in claim 13, wherein the controller generates a control signal to stop an operation of the accessory apparatus which is determined to be the lost article and transmits the control signal to the accessory apparatus which is determined to be the lost article.

18. The host apparatus as claimed in claim 13, wherein the controller generates information to indicate that the accessory apparatus is the lost article and transmits the information to the accessory apparatus which is determined to be the lost article.

19. The host apparatus as claimed in claim 11, wherein the external server is a lost article management server which receives the corresponding information and determines whether the accessory apparatus is a lost article.

20. An accessory apparatus which performs authentication with a host apparatus, the accessory apparatus comprising:

an authentication request unit which transmits authentication information to the host apparatus and requests authentication by the host; and

a controller which, according to a result of the authentication by the host, receives preset setting information from the host apparatus and sets a function corresponding to the received setting information.
