Smart Access Control System Using Electronic Card and Biometric Verification
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional access control systems are complex and inefficient, requiring manual processes and multiple steps for visitors to gain access, often involving manual input of codes or biometric data, which can be error-prone and time-consuming.
Innovation Solution
A smart access control system that uses an electronic card storing a card number and identifying data, interacting with a server and electronic lock device, which generates an access code and verifies biometric data to unlock the door, simplifying the access process by integrating card-based and biometric authentication.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If manual processes and multiple steps are used for access control, then security verification can be performed, but the access process becomes complex and time-consuming
Solution Approach 1:
The patent combines card-based authentication and biometric verification into a single integrated access control system. The server simultaneously processes both authentication methods and generates one unified access code, merging multiple verification steps into a coordinated automated process that maintains security while reducing operational complexity
Solution Approach 2:
The system performs preliminary authentication by verifying the electronic card and biometric data before generating the access code. This preliminary verification ensures security requirements are met before the final access decision is made, allowing the system to maintain high security standards while streamlining the overall process
2Ease of operation
If manual input of codes or biometric data is required, then access control can be implemented, but errors increase and efficiency decreases
Solution Approach 1:
The system enables self-service access control by automatically reading the electronic card data and capturing biometric information without requiring manual data entry. The server autonomously processes the authentication and generates the access code, eliminating human error from manual input while reducing the time required for the access process
3Reliability
If card-based and biometric authentication are integrated, then security is enhanced, but system complexity increases
Solution Approach 1:
The server acts as an intermediary that coordinates between the card reading device, biometric scanner, and electronic lock. It receives data from multiple authentication sources, processes them centrally, and generates a single access code that reflects both verification methods. This intermediary approach enhances security through multiple verification layers while managing system complexity by centralizing the processing logic
Data Source
AI summary
A system adapted to interact with an electronic card includes a server and an electronic lock device. The electronic lock device is configured to switch between a locked state and an unlocked state. The server, in response to an access request associated with the electronic card, generates and transmits an access code to the electronic lock device. The electronic lock device is configured to, in response to an input code, compare the input code with the access code, receive input data from a user, access the electronic card to obtain identifying data, and, when the input code is identical to the access code and the input data matches the identifying data, switch to the unlocked state.
