Authentication Information Management Server for IC Chip Applications
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing non-contact IC chip systems require complex procedures and incur additional maintenance costs to share authentication information, such as passwords, between applications, as they lack the necessary components for dynamic password generation and notification.
Innovation Solution
An authentication information management system and server that enables communication between an information processing terminal with an IC chip and a network, allowing for the setting and notification of authentication information between memory areas, facilitating secure sharing of authentication data between applications through an authentication information management server.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If password authentication function is validated for each individual memory area, then security is improved, but accessibility for other applications deteriorates
Solution Approach 1:
The patent introduces a server as an intermediary between applications and memory areas. The server stores authentication information centrally and provides it to authorized applications through controlled access. This mediator enables applications to access memory areas without directly sharing passwords, maintaining security while improving accessibility.
2Adaptability or versatility
If password is shared among plural applications preliminarily, then accessibility is improved, but device complexity increases
Solution Approach 1:
The patent extracts the authentication information management function from the IC chip and relocates it to an external server. This separation allows the IC chip to remain simple while the server handles the complexity of authentication management, including storing authentication information and controlling access to multiple applications.
3Adaptability or versatility
If dynamic password generation and notification sections are added to information processing terminal, then accessibility is improved, but device complexity increases
Solution Approach 1:
The server acts as an intermediary that performs dynamic password generation and notification functions externally. Instead of adding these complex sections to the information processing terminal, the server handles authentication information management centrally, allowing terminals to access authenticated data without possessing the complexity of password generation and distribution systems.
