NFC Authentication via Proximity Detection
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing NFC-based systems lack an intuitive operation method for users to perform actions on NFC devices, such as selecting objects for execution, which limits user interaction.
Innovation Solution
An information processing apparatus and method that utilizes NFC for user authentication and data exchange between NFC-mounted devices, allowing intuitive operation through touch-based interactions, with a system configuration including an image forming apparatus, mobile terminal, NFC card, and wireless LAN access point, enabling NFC communication and authentication processes.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If NFC is used for data exchange between devices, then communication versatility is improved, but user interaction intuitiveness deteriorates because users must select objects on a display rather than performing direct touch operations
Solution Approach 1:
The NFC system automatically performs data exchange and authentication functions when devices are brought into proximity, eliminating the need for users to manually select objects on a display. The system self-initiates the communication process based on the physical proximity of devices, making the interaction as intuitive as a simple touch gesture.
2Adaptability or versatility
If traditional RFID tags are used for authentication, then authentication function is achieved, but operational flexibility deteriorates compared to NFC which supports multiple functions including peer-to-peer communication and card emulation
Solution Approach 1:
The patent implements NFC with three operational modes: reader/writer mode for data exchange with NFC tags, peer-to-peer mode for direct device-to-device communication, and card emulation mode for acting as a virtual card. This multi-functional design allows a single NFC interface to replace multiple separate systems (RFID tags, wireless communication modules, card readers), reducing overall system complexity while enhancing versatility.

AI summary
There is provided an information processing apparatus (100, 200) and a control method thereof. The information processing apparatus and a control method acquires user information from an external apparatus (300, 400) by using near field wireless communication, determines how to handle the acquired user information according to a type of a screen displayed by a display unit. For example, when the displayed screen is an authentication screen, authentication processing is executed by using the acquired user information.
