Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing web service authentication methods are suboptimal, requiring users to manually input credentials and lacking efficient, secure, and seamless authentication processes, especially when accessing services from different devices or systems.
Innovation Solution
A system and method using a smart device app that authenticates users through a secure token, biometric verification, and image/audio decoding, allowing for secure and seamless access to web services without manual credential input, utilizing device identifiers and short-lived codes for enhanced security and convenience.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If conventional authentication methods (user identifier and password) are used, then users can access web services, but the authentication process is manual, time-consuming, and suboptimal
Solution Approach 1:
The patent replaces manual mechanical authentication (typing username and password) with automated optical recognition. The camera captures an image of the authentication code displayed on the screen, and image processing automatically extracts and verifies the code, eliminating the need for manual input and reducing authentication time
Solution Approach 2:
The system enables self-service authentication where the user's device automatically captures and processes the authentication code without requiring manual intervention. The camera automatically detects the code, the image processing automatically extracts it, and the system automatically verifies it against the server, creating a seamless self-service authentication flow
2Reliability
If manual credential input is required, then authentication can be performed, but security is compromised and user convenience is reduced
Solution Approach 1:
The patent replaces vulnerable manual credential input with automated image capture and optical code recognition. The camera captures the authentication code displayed on the screen, and image processing automatically extracts and verifies it, eliminating the security risks associated with manual password entry while maintaining ease of operation
Solution Approach 2:
The patent introduces an intermediary authentication code displayed on the screen that serves as a mediator between the user and the authentication system. Instead of directly inputting passwords, users interact with the visual code, which is then captured and verified automatically, providing an additional layer of security while improving user experience
3Adaptability or versatility
If authentication is performed from different devices or systems, then web services can be accessed more flexibly, but authentication complexity increases
Solution Approach 1:
The patent creates a universal authentication mechanism that works across different devices and platforms. The authentication code is displayed in a standardized format that can be captured by any device with a camera, and the image processing algorithm can extract and verify the code regardless of the capturing device, enabling flexible cross-device authentication without increasing system complexity
Solution Approach 2:
The patent uses the authentication code as a copyable credential that can be captured and transferred between devices. The code displayed on the screen serves as a universal credential that can be photographed and verified by any device, eliminating the need for device-specific authentication mechanisms and simplifying the overall authentication system
