Server Biometric Authentication for IC Card Password Management
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Users of multi-application IC cards face the challenge of managing and remembering multiple passwords for different applications, leading to confusion and potential authentication failures.
Innovation Solution
A server-based system that performs biometric authentication and automatically retrieves and transmits the correct password for an IC card application, eliminating the need for users to remember individual passwords by associating biometric information with application identification and password data in a database.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If users set different passwords for different applications on an IC card, then each application can be securely authenticated, but users must memorize multiple passwords which increases operational complexity
Solution Approach 1:
The patent introduces a server as an intermediary between the user and the IC card applications. The server stores the mapping between biometric information and passwords, and automatically provides the correct password when the user presents their biometric data. This mediator eliminates the need for users to memorize multiple passwords while maintaining secure authentication for each application.
Solution Approach 2:
The system enables self-service authentication where the server automatically retrieves and provides the appropriate password based on the user's biometric verification. The user simply needs to present their biometric data (fingerprint, face, etc.), and the server handles the password retrieval and transmission to the IC card processing apparatus, eliminating manual password recall and entry.
2Reliability
If users memorize multiple passwords for different applications, then authentication can be performed, but users are likely to forget which password corresponds to which application
Solution Approach 1:
The server acts as an intermediary that stores and manages the mapping relationship between biometric information and passwords for different applications. When a user presents their biometric data, the server automatically determines which application is being accessed and provides the corresponding password, eliminating the burden on users to remember the mapping between passwords and applications.
Solution Approach 2:
The system implements feedback where the server receives biometric information from the user, verifies it against stored data, and automatically provides the appropriate password feedback. This closed-loop process ensures that the correct password is always provided based on the user's biometric verification, preventing user confusion about password-to-application mapping.
Data Source
AI summary
A server has a communication interface, a database, a biometric authentication means, a password specifying means, and a password transmission means. The database stores information in which, for each registrant, biometric information, identification information of an application and a password are associated with one another. The biometric authentication means is configured to, upon receiving biometric information and identification information of an application from an external processing apparatus, execute biometric authentication by using the received biometric information and biometric information of a registrant registered in the database. If biometric authentication is successful, the password specifying means refers to the database and specifies a password corresponding to the identification information of a successfully authenticated registrant. The password transmission means transmits the specified password to the external processing apparatus via the communication interface.
