Biometric Data Card with Central Server Verification
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing smart card security measures, including biometric authentication, can be circumvented, leaving them vulnerable to hacking and unauthorized use, especially with the increasing adoption of contactless transactions that reduce user interaction and oversight.
Innovation Solution
A data card equipped with a biometric sensor, such as a fingerprint scanner, that requires user contact to activate the processor and verify identity through a biometric sample, disabling the card if the user is not authorized, and includes a communications module for secondary verification with a central server to ensure secure transactions.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If biometric authentication is implemented to verify user identity, then security is improved, but the system becomes vulnerable to circumvention and hacking
Solution Approach 1:
The patent introduces a central server as an intermediary between the card and the authentication system. The server receives biometric data from the card, performs verification, and controls the card's activation state. This intermediary layer prevents direct circumvention of the authentication mechanism by centralizing the verification logic and controlling card functionality remotely.
Solution Approach 2:
The system implements feedback mechanisms where the central server continuously monitors card usage and biometric verification results. Based on this feedback, the server can deactivate the card if unauthorized access is detected, creating a closed-loop security system that adapts to attack patterns and prevents circumvention attempts.
2Ease of operation
If contactless transactions are adopted to reduce user interaction, then ease of operation is improved, but security is worsened due to reduced oversight
Solution Approach 1:
The patent replaces traditional mechanical contact-based authentication with contactless biometric verification. The biometric sensor captures user identification data without physical contact, and the central server validates this data remotely. This substitution maintains ease of operation while enhancing security through sophisticated authentication mechanisms.
Solution Approach 2:
The central server acts as an intermediary that processes contactless transactions securely. It receives transaction data from the card, verifies biometric authentication, and controls card activation without requiring physical contact. This intermediary layer enables contactless operations while maintaining strong security oversight.
3Reliability
If the card is deactivated after failed biometric verification to prevent unauthorized use, then security is improved, but legitimate users experience loss of time
Solution Approach 1:
The system performs preliminary biometric verification before activating the card for transactions. By pre-authenticating the user through the central server, the system ensures security is established before any transaction occurs, preventing unauthorized use while allowing legitimate users to access their cards quickly without repeated delays.
Solution Approach 2:
The central server provides immediate feedback on biometric verification results to the card system. When verification succeeds, the card is quickly activated; when it fails, the card is deactivated. This feedback mechanism optimizes the balance between security and user convenience by making authentication decisions rapid and definitive.
Data Source
AI summary
The present invention is directed to a data card. The data card includes a biometric sensor, at least one processor wherein the at least one processor is operable on contact by a user with said biometric sensor whereon said processor is adapted to obtain a reading from the biometric sensor to verify that the user is an authorised user and prohibit further card usage in the event that the user is not an authorised user.
