Abstract
An image forming apparatus for authenticating a near field communication (NFC) device, which receives information about an application being executed on an NFC device when the NFC device is tagged, determines an authentication method based on the received information, receives and authenticates a log in information corresponding to the determined authentication method from the NFC device, and allows the use of the image forming apparatus based on a result of authentication.
Claims17
An image forming apparatus for authenticating an external near field communication (NFC) device, comprising:
- an NFC module configured to receive an application identification of an application being executed on the NFC device when the NFC device is tagged;
- and
- a control unit configured to determine an authentication method corresponding to the application based on the received application identification,
- wherein the application identification includes information for identifying the authentication method that is executable via the application installed in the NFC device,
- wherein the application identification includes different information according to types of the application installed in the NFC device, and
- wherein the control unit is further configured to:
- authenticate log in information corresponding to the determined authentication method, received from the NFC device via the NFC module, and
- allow use of the image forming apparatus based on a result of authentication.
A near field communication (NFC) device for authenticating an image forming apparatus, comprising:
- a control unit configured to execute an application that conducts an authentication operation via NFC;
- and
- an NFC module, when the image forming apparatus is tagged, is configured to:
- transmit an application identification including information for identifying an authentication method that is executable via the application installed in the NFC device,
- receive information for the authentication method corresponding to the executed application from the image forming apparatus, and
- transmit log in information corresponding to the authentication method to the image forming apparatus,
- wherein the application identification includes different information according to types of the application installed in the NFC device, and
- wherein the control unit is further configured to provide a result of authentication of the log in information transmitted from the image forming apparatus and received from the image forming apparatus via the NFC module, via the application.
A method of authenticating an external near field communication (NFC) device in an image forming apparatus, the method comprising:
- receiving an application identification regarding an application being executed on the NFC device when the NFC device is tagged;
- determining an authentication method corresponding to the application based on the received application identification;
- receiving log in information corresponding to the determined authentication method from the NFC device;
- and
- allowing use of the image forming apparatus by authenticating the NFC device by using the received log in information,
- wherein the application identification includes information for identifying the authentication method that is executable via the application installed in the NFC device, and
- wherein the application identification includes different information according to types of the application installed in the NFC device.
A method of authenticating an external near field communication (NFC) device to an image forming apparatus, the method comprising:
- executing an application that conducts an authentication operation via NFC;
- transmitting an application identification including information for identifying an authentication method that is executable via the application installed in the NFC device;
- receiving information for the authentication method corresponding to the executed application from the image forming apparatus when the image forming apparatus is tagged;
- transmitting log in information corresponding to the authentication method from the image forming apparatus;
- and
- providing a result of authentication by using the log in information transmitted from the image forming apparatus, via the application,
- wherein the application identification includes different information according to types of the application installed in the NFC device.
