Abstract

A relay apparatus, capable of relaying communication between a communication apparatus and a server, communicates with the communication apparatus and the server through first wireless communication, and carries out control for determining whether or not to permit the communication apparatus to communicate with the server through the first wireless communication in response to a request received from the communication apparatus, that is based on a predetermined protocol. The relay apparatus sends the request to the server and receives data written in a predetermined format as a response to the request, and carries out the control based on the data.

Claims

1. A relay apparatus capable of relaying communication between a communication apparatus and an authorization server, the relay apparatus comprising:

a display unit;

at least one processor; and

at least one memory storing code to be executed by the at least one processor, wherein

the at least one processor executes the code to function as;

a first display control unit configured to cause the display unit to display a user authentication screen requiring a user to input user authentication information to be used for user authentication in a case where the relay apparatus receives an authorization request sent from the communication apparatus through first wireless communication;

a first sending unit configured to send, to the authorization server, user authentication information which is inputted by the user on the user authentication screen,

a second display control unit configured to cause the display unit to display an access authority granting screen requiring the user to input whether or not to authorize the communication apparatus in a case where a user authentication process succeeds at the authorization server based on the user authentication information sent by the first sending unit;

a receiving unit configured to receive an authorization response sent from the authorization server in a case where authorizing the communication apparatus is inputted by the user on the access authority granting screen; and

a second sending unit configured to send, to the communication apparatus, the authorization response received by the receiving unit through the first wireless communication.

2. The relay apparatus according to claim 1,

wherein the display unit displays the user authentication screen written in a predetermined format received from the authorization server.

3. The relay apparatus according to claim 2,

wherein the display unit displays the access authority granting screen written in the predetermined format received from the authorization server.

4. The relay apparatus according to claim 3,

wherein the predetermined format is HTML.

5. The relay apparatus according to claim 1,

wherein the user authentication information is a user ID or a password.

6. The relay apparatus according to claim 1, further comprising a relaying unit configured to send, to the authorization server, the authorization request which is sent from the communication apparatus.

7. The relay apparatus according to claim 1, further comprising a communication unit configured to communicate with the communication apparatus through a second wireless communication whose transfer speed is slower than the first wireless communication.

8. The relay apparatus according to claim 7,

wherein before communicating through the first wireless communication, the communication unit uses the second wireless communication to set parameters required by the first wireless communication with the communication apparatus.

9. The relay apparatus according to claim 8,

wherein the first wireless communication is a wireless LAN and the second wireless communication is an NFC (Near Field Communication) or Bluetooth.

10. The relay apparatus according to claim 1,

wherein the user authentication process complies with an OAuth protocol.

11. The relay apparatus according to claim 1,

wherein the display unit displays the user authentication screen by using a web browser.

12. A control method for a relay apparatus capable of relaying communication between a communication apparatus and an authorization server, the method comprising:

displaying on a display unit of the relay apparatus a user authentication screen requiring a user to input user authentication information to be used for user authentication in a case where the relay apparatus receives an authorization request sent from the communication apparatus through first wireless communication;

sending, to the authorization server, user authentication information which is inputted by the user on the user authentication screen;

displaying on the display unit of the relay apparatus an access authority granting screen requiring the user to input whether or not to authorize the communication apparatus in a case where a user authentication process succeeds at the authorization server based on the user authentication information;

receiving an authorization response sent from the authorization server in a case where authorizing the communication apparatus is inputted by the user on the access authority granting screen; and

sending, to the communication apparatus, the authorization response through the first wireless communication.

13. A system comprising a communication apparatus and a relay apparatus,

wherein the relay apparatus includes:

a display unit;

at least one processor; and

at least one memory storing code to be executed by the at least one processor, wherein

the at least one processor executes the code to function as;

a first display control unit configured to cause the display unit to display a user authentication screen requiring a user to input user authentication information to be used for user authentication in a case where the relay apparatus receives an authorization request sent from the communication apparatus through first wireless communication;

a first sending unit configured to send, to the authorization server, user authentication information which is inputted by the user on the user authentication screen,

a second display control unit configured to cause the display unit to display an access authority granting screen requiring the user to input whether or not to authorize the communication apparatus in a case where a user authentication process succeeds at the authorization server based on the user authentication information sent by the first sending unit;

a receiving unit configured to receive an authorization response sent from the authorization server in a case where authorizing the communication apparatus is inputted by the user on the access authority granting screen; and

a second sending unit configured to send, to the communication apparatus, the authorization response received by the receiving unit through the first wireless communication; and

wherein the communication apparatus includes;

a communication unit configured to communicate with the relay apparatus through the first wireless communication; and

a determination unit configured to determine whether or not to grant access to a server via the relay apparatus through the first wireless communication based on the authorization response received by the communication unit.

14. A non-transitory computer-readable storage medium storing a computer program for causing a computer to execute a method of a relay apparatus capable of relaying communication between a communication apparatus and an authorization server, the method comprising:

displaying on a display unit of the relay apparatus a user authentication screen requiring a user to input user authentication information to be used for user authentication in a case where the relay apparatus receives an authorization request which is sent from the communication apparatus and the server through first wireless communication;

sending, to the authorization server, user authentication information which is inputted by the user on the user authentication screen;

displaying on the display unit of the relay apparatus an access authority granting screen requiring the user to input whether or not to authorize the communication apparatus in a case where a user authentication process succeeds at the authorization server based on the user authentication information;

receiving an authorization response which is sent from the authorization server in a case where authorizing the communication apparatus is selected by the user in the access authority granting screen; and

sending, to the communication apparatus, the authorization response through the first wireless communication.
