Intercom Network NFC Authorization for Fast Secure Registration
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing intercom networks for live events require manual password entry for mobile device authorization, which is time-consuming and distracts operators from other tasks, and lack secure, convenient methods for device registration.
Innovation Solution
Implementing NFC elements on stationary and mobile devices for automatic authorization information transfer, eliminating the need for manual password entry and enhancing security and convenience during device registration.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If manual password entry is used for mobile device authorization, then security is maintained through verification, but operator time is consumed and distraction from other tasks increases
Solution Approach 1:
The system pre-stores authorization data (passwords or unique device identifiers) in the stationary element before mobile devices arrive. When a mobile device approaches, the system automatically retrieves and verifies the pre-stored authorization data without requiring manual password entry, thus maintaining security while eliminating time loss.
Solution Approach 2:
The patent replaces the manual mechanical process of password entry and verification with an automated electronic system. The stationary element automatically detects the mobile device, retrieves pre-stored authorization data, performs verification, and grants access without human intervention, substituting manual operations with automated electronic processes.
2Reliability
If manual password entry is required for device registration, then authorization control is maintained, but ease of operation deteriorates due to complex registration process
Solution Approach 1:
The mobile device performs self-service registration by automatically transmitting its unique device identifier to the stationary element. The stationary element autonomously verifies this identifier against pre-stored authorization data and completes the registration process without requiring operator intervention, thus maintaining authorization control while dramatically improving ease of operation.
Solution Approach 2:
The manual mechanical process of password entry and verification is replaced with an automated electronic system. The stationary element automatically detects the mobile device, retrieves pre-stored authorization data, performs verification, and grants access without human intervention, substituting manual operations with automated electronic processes.
3Ease of operation
If NFC elements are added to stationary and mobile devices for automatic authorization, then ease of operation and registration speed improve, but device complexity increases
Solution Approach 1:
The NFC element in the stationary element serves multiple functions: it stores authorization data for multiple mobile devices, automatically detects approaching mobile devices, retrieves and verifies authorization data, and manages registration. This multi-functionality justifies the added complexity by eliminating the need for separate manual authorization processes.
Solution Approach 2:
The NFC element acts as an intermediary between the mobile device and the authorization system. It automatically exchanges authorization data with approaching mobile devices without requiring manual intervention, serving as a mediator that simplifies the interaction while handling the complexity of authorization management internally.
