Authentication Data Conversion for Unknown Card Formats
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing user authentication systems for devices like printers face challenges in correctly obtaining authentication information due to varying data formats from card readers, leading to improper user authentication when data format information cannot be identified.
Innovation Solution
An information processor with a read information obtaining unit, conversion unit, authentication information obtaining unit, and conversion method setting unit that converts read information using a predetermined method, allowing for the selection and setting of a specific conversion method that matches comparative-purpose authentication information, ensuring accurate user authentication even with unknown data formats.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If data format information is not identified by the multifunction machine, then user authentication cannot be performed, but the system cannot adapt to various card reader formats
Solution Approach 1:
The system performs preliminary actions by sending test read information to the server device before actual authentication. The server device pre-identifies the data format and determines the appropriate conversion method, so when actual authentication occurs, the conversion method is already established, ensuring both reliability and adaptability.
Solution Approach 2:
The server device acts as an intermediary between the multifunction machine and the authentication system. It receives read information, identifies data formats, determines conversion methods, and returns the appropriate conversion method to the multifunction machine, enabling the system to handle various card reader formats without compromising authentication reliability.
2Adaptability or versatility
If multiple conversion methods are available, then the system can handle various formats, but it becomes difficult to select the correct conversion method
Solution Approach 1:
The system implements feedback by sending test read information to the server device and receiving feedback in the form of the determined conversion method. The server device tests the read information with multiple conversion methods and returns the one that successfully converts the data, eliminating the complexity of selection from the multifunction machine.
Solution Approach 2:
The server device performs self-service by automatically identifying the data format and selecting the appropriate conversion method without requiring manual intervention or complex selection logic in the multifunction machine. The system autonomously determines the correct conversion method through automated format identification and conversion method determination.

AI summary
An information processor includes a read information obtaining unit, a conversion unit, an authentication information obtaining unit, and a conversion method setting unit. The read information obtaining unit obtains read information read from an authentication medium by a reading device. The conversion unit converts the read information in accordance with a predetermined conversion method. The authentication information obtaining unit obtains comparative-purpose authentication information to be used for a comparison with the converted read information. The conversion method setting unit sets, when the converted read information and the comparative-purpose authentication information match each other, the conversion method as a particular conversion method used to convert the read information read by the reading device.
