Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If multiple fingerprint recognition algorithms are applied to enhance security, then the level of security is improved, but the processing demands and time required increase significantly
Solution Approach 1:
The fingerprint image is divided into multiple sub-images (e.g., left half and right half), and independent fingerprint recognition is performed on each sub-image. This segmentation allows parallel processing and reduces the computational burden on any single algorithm while maintaining high security through multiple verification points.
Solution Approach 2:
Instead of processing a single large fingerprint image with multiple algorithms sequentially, the invention transitions to processing multiple smaller sub-images in parallel. This dimensional change from one large image to multiple smaller images enables concurrent execution of recognition algorithms, significantly reducing total processing time while maintaining equivalent or enhanced security.
2Measurement precision
If the size of fingerprint test image is increased to improve recognition accuracy, then measurement precision is improved, but processing demands increase quadratically
Solution Approach 1:
The fingerprint image is segmented into multiple smaller sub-images, each of which is processed independently. This segmentation reduces the processing demands on each individual algorithm while maintaining sufficient precision through multiple verification points. The sum of processing requirements for multiple small sub-images is less than processing a single large image.
Solution Approach 2:
Instead of processing the entire fingerprint image with a single algorithm, the invention applies multiple algorithms to multiple sub-images. This partial action approach processes only portions of the image with each algorithm, reducing overall computational complexity while achieving high recognition accuracy through cumulative verification.
3Reliability
If multiple authentication methods are combined to increase security, then reliability is improved, but device complexity and implementation difficulty increase
Solution Approach 1:
The invention uses the same fingerprint recognition algorithm multiple times on different sub-images, making the system more universal rather than requiring multiple different algorithms. This approach maintains high security through repeated verification while avoiding the complexity of integrating and coordinating multiple different authentication algorithms.
Solution Approach 2:
By segmenting the fingerprint image into sub-images and applying the same algorithm to each, the system achieves multi-verification without the complexity of multi-algorithm integration. The segmentation allows independent processing of each sub-image while maintaining consistent verification criteria across all segments.

AI summary
A method for authenticating an identity of a person may involve acquiring a sample fingerprint image of a finger of the person. Two or more sub-portions may be extracted from the sample fingerprint image to form a plurality of fingerprint test images. A fingerprint recognition may be independently run on the plurality of fingerprint test images. The identity of the person may be authenticated upon a positive outcome from the independently run finger-print recognitions. A device may be provided for authenticating an identity of a person.
