Image forming apparatus and near field communication (NFC) device supporting NFC function and method of performing authentication thereof cross-reference to related applications

摘要

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.

主权项

1. 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, andallow use of the image forming apparatus based on a result of authentication.
