Dynamic Passcode Door Entry via QR Code Authentication
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing door entry systems face challenges in maintaining security and efficiency, as static passcodes can be compromised, and biometric systems require extensive setup for new users, while also needing secure communication networks.
Innovation Solution
A secure door entry system utilizing a QR code that establishes a communications channel between a mobile device and a remote authentication system, allowing dynamic passcode generation and distribution without requiring extensive communication infrastructure, enabling regular passcode changes and easy access for visitors.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If a static passcode is used in a simple door entry system, then the system is easy to operate and does not require human supervision, but the passcode is susceptible to being compromised and cannot be easily changed without communicating with all authorized persons
Solution Approach 1:
The system transitions from static passcodes to dynamic passcodes that are generated on-demand through the mobile communication device. The passcode is no longer a fixed value but changes based on authentication requests, making the system both easy to operate (automatic unlocking) and secure (dynamic codes that cannot be compromised).
Solution Approach 2:
A mobile communication device (SMS gateway) is introduced as an intermediary between the door entry system and the authorized persons. This intermediary enables secure passcode distribution without requiring direct communication between the door system and each user, resolving the contradiction between ease of operation and security.
2Reliability
If biometric authentication is used to enhance security, then unauthorized access is prevented, but the system requires coupling to a secure communication network and database for storing biometric data
Solution Approach 1:
The complex biometric authentication system and its associated database infrastructure are extracted from the door entry system. Instead of requiring a secure communication network and database, the patent uses a simplified authentication mechanism where the mobile communication device serves as the authentication medium, eliminating the need for complex infrastructure while maintaining security.
Solution Approach 2:
The system replaces expensive, permanent biometric databases with a simpler, temporary passcode system delivered via mobile communication. The passcode is a transient credential that can be generated and discarded easily, reducing infrastructure complexity while maintaining authentication security.
3Reliability
If biometric data is stored in a database for authentication, then authorized persons can be authenticated, but adding new persons or temporary visitors is time-consuming as biometric data must be captured and stored in advance
Solution Approach 1:
The system performs preliminary authentication through the mobile communication device before granting access. Instead of requiring advance setup of biometric data, the authentication is handled in real-time through the SMS gateway, allowing immediate access for both existing and new authorized persons without time-consuming setup procedures.
Solution Approach 2:
The mobile communication device serves as a self-service authentication mechanism. Authorized persons can authenticate themselves independently without requiring administrative setup of biometric data. The system automatically handles authentication requests through the mobile device, eliminating the need for manual biometric enrollment and reducing setup time to near zero.

AI summary
A method for controlling access to a secure area via an electronic door entry system includes the steps of: displaying a bar code associated with the door entry system which can be read by a smartphone, the bar code encoding instructions for establishing a communications channel between the smartphone and a remote authentication system where a passcode for the door entry system can be obtained by an authorized person; receiving authentication data for a person over the communications channel from the smartphone; authenticating a person based on the authentication data; communicating a passcode to the smartphone; receiving a passcode input at the door entry system; verifying the passcode; and, generating a door lock release signal for the door entry system if the passcode is verified.
