Device Connection Control via Pre-stored Authentication Data
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
The inconvenience of repeatedly inputting identification and authentication information to connect devices within a home network, especially when managing shared products and connecting to external networks, is a significant challenge due to the need for individual accounts for each family member.
Innovation Solution
A method and apparatus that allow direct device connection via a network without a server by pre-storing device information, where a device detects and authenticates other devices by requesting and using stored authentication information if they are not already registered, enabling automatic connection without manual input.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If general account authentication method is used to connect devices, then security is improved, but ease of operation deteriorates due to repeated text input of ID and password
Solution Approach 1:
The patent applies preliminary action by pre-storing authentication information in a data store before actual connection is needed. When a device attempts to connect, the system automatically retrieves pre-stored authentication data without requiring user input, thus maintaining security while improving convenience.
Solution Approach 2:
The system performs self-service authentication by automatically managing the authentication process without user intervention. The device autonomously retrieves and uses stored authentication information from the data store, eliminating the need for manual ID and password entry while maintaining secure authentication.
2Ease of operation
If authentication information is stored in a data store for automatic retrieval, then ease of operation is improved, but device complexity increases
Solution Approach 1:
The patent applies universality by implementing a centralized data store that serves multiple devices and multiple authentication scenarios. This single data store structure handles authentication for various device types and connection scenarios, reducing overall system complexity compared to having separate authentication mechanisms for each device pair.

AI summary
A method and apparatus for controlling connection between devices includes detecting a first device, determining whether the first device is included in a device list, obtaining information related to the first device from a second device, and establishing a connection with the first device based on the information from the second device.
