Wireless Credential Validation Using Periodic Broadcast
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing methods for validating access rights in digitized service industries, such as sports arenas, are inefficient due to persistent connections between user devices and access control devices, leading to delays and packet loss, especially in high-traffic scenarios, and manual validation methods are time-consuming.
Innovation Solution
Implementing a system where credential data is wirelessly transmitted to a remote server for validation upon determining the presence of an access control device within a predetermined range, using protocols like Bluetooth Low Energy (BLE), eliminating the need for persistent connections and enabling efficient access management.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Speed
If automatic validation using persistent connections is implemented, then validation speed is improved, but system reliability deteriorates due to packet loss and connection blocking
Solution Approach 1:
The access control device uses periodic broadcasting of validation requests instead of persistent connections. The device broadcasts validation requests at regular intervals, and user devices respond when present, eliminating the need for continuous connection while maintaining validation capability.
Solution Approach 2:
The system introduces a broadcast mechanism as an intermediary between the access control device and user devices. Instead of direct persistent connections, the access control device broadcasts validation requests through the air, and user devices with valid credentials respond, serving as intermediaries in the communication process.
2Device complexity
If manual validation method is used, then system complexity is reduced, but productivity deteriorates due to time-consuming validation process
Solution Approach 1:
The validation system operates autonomously without manual intervention. The access control device automatically broadcasts validation requests, detects user devices within range, receives credential data, validates access rights, and manages entry control without requiring human operators.
Solution Approach 2:
The patent replaces manual mechanical validation processes with wireless communication-based automatic validation. Instead of physical manual checking, the system uses Bluetooth Low Energy wireless communication to transmit and validate credentials electronically, significantly increasing validation throughput.
3Reliability
If persistent connection is maintained between user device and access control device, then validation reliability is improved, but device complexity increases due to connection management
Solution Approach 1:
Instead of maintaining persistent connections, the access control device broadcasts validation requests periodically. This approach reduces connection management complexity while maintaining reliable validation through regular broadcast cycles that ensure all nearby devices have a chance to respond.

AI summary
Techniques for facilitating validation of access rights corresponding to a restricted setup are described. According to the techniques, a user device detects presence of a control device within a predetermined range of the user device wirelessly. On detecting the control device to be within the predetermined range, the user device transmits credential data to a remote server wirelessly. The credential data is indicative of access rights corresponding to the restricted setup. The user device receives a notification indicating validity of the credential data from the remote server wirelessly. Valid credential is to be used by a user of the user device to access the restricted setup.
