E-paper Authorization System Preventing Network Interception
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional wireless network equipment and authorization systems are vulnerable to hacking due to the use of easily guessable and unchanged initial user names and passwords, and they face information security risks from intercepting public keys and password leakage during network transmission.
Innovation Solution
An authorization method and system that uses an e-paper on the service device to display authorization information, which is then obtained by the user device through a non-electrical channel, preventing interception and enhancing security by eliminating the need for password transmission over communication networks.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If authorization information is transmitted through communication network, then user device can obtain authorization information, but illegal device may intercept and replace public key or steal password
Solution Approach 1:
The patent introduces e-paper as an intermediary medium to display authorization information. Instead of transmitting authorization information directly through the communication network, the service device displays the information on the e-paper, and the user device obtains it from the e-paper. This intermediary approach prevents illegal devices from intercepting the authorization information during network transmission, while still enabling the user device to obtain the necessary information for authorization operations.
2Ease of operation
If initial user name and password are used for authorization, then authorization operation can be performed, but the safety factor is low due to easily guessable credentials
Solution Approach 1:
The patent applies preliminary action by having the service device generate and display a temporary password on the e-paper before the authorization operation. This temporary password is provided in advance through the e-paper display, allowing the user device to obtain it without relying on easily guessable initial credentials. The temporary password is then used for the authorization operation, enhancing security while maintaining ease of operation.
Data Source
AI summary
An authorization method and an authorization system are provided. The authorization method includes displaying, by a service device, authorization information on an e-paper arranged on the service device; obtaining, by a user device, the authorization information from the e-paper; and using, by the user device, the authorization information displayed on the e-paper to perform an authorization operation between the user device and the service device.
