Unified Authentication for Communication Devices via Signal Format Detection
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing communication devices face challenges in authenticating multiple types of devices due to differing ID formats and data sizes, requiring multiple programs to handle various rules for each device type.
Innovation Solution
A communication device with a wireless interface and processor that receives signals using a predetermined standard, determines format support, and executes authentication using common identification information from signals supporting the standard, allowing for unified authentication across different device types.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If multiple programs are used to handle different device types with varying ID formats, then authentication coverage is improved, but device complexity increases
Solution Approach 1:
The terminal is designed with a universal authentication program that can handle multiple device types (non-contact IC cards, mobile phones, etc.) through a single unified interface. The system automatically adapts to different device types by selecting appropriate reading rules based on the detected device, eliminating the need for multiple separate programs while maintaining broad authentication coverage
Solution Approach 2:
An intermediary layer is introduced between the terminal and target devices that automatically translates different device-specific ID formats into a unified internal representation. This mediator component handles the complexity of format conversion internally, allowing the terminal to interact with diverse devices through a single standardized interface without requiring multiple specialized programs
2Measurement precision
If device-specific reading rules are implemented for each device type, then measurement precision of ID reading is improved, but ease of operation deteriorates
Solution Approach 1:
The terminal employs dynamic rule selection that automatically adapts to the type of device being authenticated. When a target device is detected, the system dynamically selects the appropriate reading rule set specific to that device type, ensuring optimal reading accuracy for each device while maintaining a uniform user interface that does not require users to manually configure or understand the different rules

AI summary
A communication device may receive any one signal among two or more types of signals from a target device, receive format information from the target device, receive a specific signal including information described in the predetermined format from the target device in a case where the format information indicates that the target device supports the predetermined format, determine whether or not related information related to a predetermined application software is included in the specific signal, and execute an authentication of the target device by using first identification information included in the specific signal in a case where it is determined that the related information is included in the specific signal, wherein the authentication of the target device by using information included in the specific signal is not executed in a case where it is determined that the related information is not included in the specific signal.
