Face Image Acquisition with Preliminary Biometric Verification
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing face image obtaining apparatuses face challenges in preventing counterfeiting user switching, as they either require reacquiring biological information during face image recording, increasing user burden, or struggle to simultaneously obtain valid biological information and face images effectively.
Innovation Solution
A method and apparatus that preliminarily obtain and determine the applicability of biological information for authentication, then use user input to match and store this information, allowing for simultaneous and efficient acquisition of face images without increasing user burden, utilizing input means like fingerprint or voiceprint recognition.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If biological information is obtained before face image recording, then counterfeiting user switching can be prevented, but the user burden increases due to need for reacquisition
Solution Approach 1:
The patent applies preliminary action by obtaining and storing biological information before the user requests a face image. The system preliminarily acquires the user's fingerprint and stores it in a database, so that when the user later requests a face image, the system can automatically match the stored fingerprint with the current input without requiring the user to re-provide biological information. This resolves the contradiction by preventing counterfeiting through preliminary verification while eliminating the need for repeated user input.
2Reliability
If biological information is obtained simultaneously with face image, then counterfeiting user switching is prevented, but it is difficult for users not accustomed to providing biological information
Solution Approach 1:
The system performs preliminary action by pre-obtaining and storing the user's biological information before the face image acquisition process. When the user requests a face image, the system automatically retrieves the stored biological information and compares it with the current input, eliminating the need for simultaneous presentation and reducing the cognitive load on users who are not accustomed to providing biometric data.
3Reliability
If biological information is reacquired during face image recording, then authentication reliability is improved, but the process complexity increases
Solution Approach 1:
The patent implements preliminary action by obtaining and storing biological information in advance before the face image recording process. The system stores the user's fingerprint data in a database during an initial registration phase, so that during subsequent face image acquisition, the system only needs to compare the stored fingerprint with the current input rather than acquiring new biological data. This simplifies the overall process while maintaining authentication reliability.

AI summary
A face image obtaining apparatus which includes: a biological information preliminarily obtaining means for preliminarily obtaining biological information of a user; a biological information determining means for determining whether the biological information obtained by the biological information preliminarily obtaining means is applicable to biometric authentication; a biological information storing means for storing the biological information as biometric authentication information if the biological information is determined to be applicable to biometric authentication by the biological information determining means; an input means for obtaining biological information of the user through inputting action of the user for obtaining a face image of the user; and a face image obtaining and storing means. The face image obtaining and storing means obtains and stores the face image of the user if the biological information obtained through the inputting action of the user matches the biometric authentication information.
