Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing access control systems rely on physical cards or devices, which are inconvenient to carry and can be lost or misused, leading to security risks due to the inability to verify the identity of the card holder.
Innovation Solution
An authority control system integrating near-field communication (NFC) technology with biometric identification, allowing for encoded data transmission and authorization type determination without the need for physical access control cards, using a biometric identification unit, NFC signal transmission unit, and NFC signal receiving unit to authenticate users based on biometric data.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If physical access control cards or magnetic buckles are used for sensing and reading, then the system can identify users, but users must carry these devices which causes inconvenience and increases the possibility of loss
Solution Approach 1:
The patent replaces the mechanical system of physical cards and magnetic buckles with a biometric identification system using optical, acoustic, or other biometric sensors. This substitution eliminates the need for users to carry physical devices while maintaining reliable identification through unique biological characteristics such as fingerprints, facial features, or voice patterns.
2Ease of operation
If access control cards are used, then user identification is possible, but the system cannot determine whether the card swiper is the authorized holder, leading to security risks
Solution Approach 1:
The patent replaces card-based identification with biometric identification that captures unique physiological or behavioral characteristics. This substitution ensures that only the authorized person can access the system, as biometric data cannot be easily transferred or shared like physical cards, thereby maintaining both operational simplicity and authorization verification reliability.
3Adaptability or versatility
If access control cards are distributed to multiple people, then access control is implemented, but the original authorized person can hand over the card to others, causing security risks
Solution Approach 1:
The patent replaces transferable physical cards with non-transferable biometric data. Each authorized person has their unique biometric characteristics stored in the system, allowing flexible access control for multiple users while ensuring that each person can only access using their own biological identifiers, thus preventing unauthorized transfer of access rights.
