Cross-Device Authentication via Server Location Matching
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Users face inconvenience and time consumption when logging into multiple terminal devices with the same account, as they need to re-enter account and password information on each device separately.
Innovation Solution
A method where a first terminal device transmits status and location information to a server upon receiving a predetermined signal, allowing the server to authenticate a second terminal device if their locations match, thereby eliminating the need for re-entering credentials.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If users log in to multiple terminal devices separately with account and password, then authentication reliability is maintained, but operation time and complexity increase
Solution Approach 1:
The system performs preliminary authentication on the first terminal device and stores the authentication status and location information on the server. When a second terminal device is used, the server compares the current location with the stored location information to automatically authenticate without requiring users to re-enter credentials, thus saving time while maintaining security
Solution Approach 2:
The server acts as an intermediary between terminal devices and authentication systems. It receives authentication information from the first terminal device, stores it along with location data, and uses this stored information to authenticate the second terminal device by comparing location information, thereby eliminating the need for repeated credential entry
2Reliability
If users log in to multiple terminal devices separately with account and password, then authentication security is maintained, but operation complexity increases
Solution Approach 1:
The system performs preliminary authentication on the first terminal device and stores the authentication status and location information on the server. When a second terminal device is used, the server compares the current location with the stored location information to automatically authenticate without requiring users to re-enter credentials, thus simplifying operations while maintaining security
Solution Approach 2:
The system copies the authentication status and location information from the first terminal device to the server's storage. This copied information is then used to authenticate the second terminal device, allowing users to access their accounts on multiple devices without repeatedly entering credentials, thereby improving ease of operation while maintaining security through location verification
3Ease of operation
If location-based authentication is implemented across multiple devices, then user convenience is improved, but system complexity increases
Solution Approach 1:
The server is designed with multi-functionality to handle both traditional credential-based authentication and location-based authentication. It stores authentication information and location information together, and can authenticate terminal devices using either method, thereby improving cross-device authentication ease without requiring separate dedicated systems for each authentication method
Data Source
AI summary
System and method are disclosed for providing authentication of a terminal device. One embodiment includes a method implemented by a first terminal device. The method may include receiving first location information and receiving a first predetermined signal. The method may also include transmitting status information and the first location information to a server upon receiving the first predetermined signal to allow the server to compare the first location information with second location information received from a second terminal device and to allow the server to transmit the status information to the second terminal device. The status information may indicate that the first terminal device is authenticated and the first location information may indicate a current location of the first terminal device.
