One Time Password Apparatus With Fingerprint Authentication
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Current one time password generating apparatuses lack user authentication validation, allowing unauthorized use if the device is lost or stolen, and are limited to authenticating only one user.
Innovation Solution
Incorporating fingerprint authentication by collecting, extracting, and comparing fingerprint feature data with pre-stored templates to generate a one time password, which combines with dynamic factors like time or events using a preset algorithm, ensuring only valid users access the password.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If fingerprint authentication is added to the one time password generating apparatus, then user authentication security is improved, but device complexity increases
Solution Approach 1:
The patent combines fingerprint authentication functionality with the one time password generating apparatus by integrating a fingerprint collecting unit, feature extracting unit, and template comparing unit into the existing device structure. This merging approach enables enhanced security through biometric verification while maintaining a unified device architecture rather than requiring separate authentication systems.
2Adaptability or versatility
If multiple fingerprint templates are stored for different users, then adaptability to multiple users is improved, but storage requirements and processing complexity increase
Solution Approach 1:
The patent implements segmentation by storing multiple fingerprint templates in separate storage units within the device, allowing each template to be independently managed and compared. The system segments the authentication process into individual template comparisons, enabling efficient multi-user support without requiring complex centralized processing of all user data simultaneously.
Solution Approach 2:
The patent applies preliminary action by pre-storing fingerprint templates in the device memory before authentication occurs. This allows the comparing unit to quickly retrieve and compare against multiple pre-loaded templates during the authentication process, eliminating the need for real-time template generation or complex on-the-fly processing.

AI summary
The invention relates to a one-time password generating method and an apparatus. The method includes steps of collecting fingerprint images, extracting fingerprint feature data from those fingerprint images, and comparing the fingerprint feature data with one or more pre-stored fingerprint feature templates for authentication. After the authentication is passed, a one-time password is generated by the corresponding fingerprint feature template or a user's secret corresponding to the template. The invention also discloses a one-time password apparatus, including a fingerprint collecting unit, a fingerprint feature extracting unit, a storage unit, a comparison unit, a one-time password generating unit, a control unit, and an output unit. By adding fingerprint authentication function to a one-time password generating apparatus, the invention avoids disadvantages such as no user authentication in the present apparatus, only for a single user, and imitation of the apparatus by others when it is lost or theft, as a result, increases security of the apparatus.
