Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Traditional CAPTCHA methods are becoming less secure due to advancements in computer technology, making it easier for machines to identify and replicate human inputs, thus compromising the security of access requests for smart glasses and other Internet platforms.
Innovation Solution
A biometric authentication method that presents verification information at varying depths corresponding to the presentation depth of the verification information, requiring users to input information that matches a reference result, thereby enhancing the accuracy and security of authentication by making it more difficult for machines to simulate human input.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If traditional CAPTCHA methods are used for biometric authentication, then the authentication system is simple to implement, but the security is compromised as machines can increasingly identify and replicate human inputs
Solution Approach 1:
The patent introduces depth information as a new dimension for verification. Instead of relying solely on 2D image recognition that machines can easily process, the system presents verification information at different depths (e.g., some elements closer to the user, others farther away). This dimensional addition makes it difficult for machines to replicate human input while maintaining system feasibility through integration with existing display technologies.
2Reliability
If depth-based verification information is presented to improve authentication security, then machine-based access is reduced, but the complexity of the verification system increases
Solution Approach 1:
The patent changes the parameter of verification information by adding depth characteristics to traditional 2D CAPTCHA elements. The verification information includes not only visual content but also depth parameters that indicate different presentation depths. This parameter expansion enhances security by requiring users to perceive and interact with multi-depth information, while the system manages this complexity through structured data formats and integration with existing display hardware.

AI summary
Biometric authentication can comprise: obtaining, in response to an access request, verification information for biometric authentication and at least one piece of depth information corresponding to at least one presentation depth of the verification information; presenting the verification information at the at least one presentation depth according to the at least one piece of depth information; obtaining verification input information in response to a verification input operation corresponding to the verification information; and comparing the verification input information with a reference verification result, to determine whether the biometric authentication succeeds. According to the embodiments of this application, verification information for biometric authentication is presented at a depth corresponding to the verification information, and whether the biometric authentication succeeds is determined by determining whether corresponding verification input information is consistent with a reference verification result, thereby improving accuracy of authentication and security of object access.
