Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing identity determination systems lack accuracy in distinguishing objects based on registration apparatus, material, and collation apparatus variations, leading to inconsistent authenticity determinations.
Innovation Solution
An identity determination apparatus and system that registers and compares image data of an object's surface patterns, utilizing a storage unit to associate registration apparatus information, material information, and collation apparatus information to enhance collation accuracy by using correlation coefficients and normalized scores for determining object identity.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Measurement precision
If a uniform collation process is used regardless of registration apparatus, collation apparatus, and material, then the system is simple to operate, but the accuracy of identity determination deteriorates
Solution Approach 1:
The patent applies local quality by creating specific collation parameter sets tailored to each combination of registration apparatus, collation apparatus, and material type. Instead of using a uniform collation process, the system selects appropriate collation parameters (such as correlation coefficient thresholds, image processing methods, and feature extraction parameters) based on the specific apparatus and material being used. This ensures optimal accuracy for each scenario while maintaining systematic management through automated parameter selection.
Solution Approach 2:
The patent implements parameter changes by dynamically adjusting collation parameters based on the registered apparatus information, collation apparatus information, and material information. The system stores multiple sets of collation parameters and selects the appropriate set based on the specific combination of apparatus and material, thereby optimizing the collation process for each scenario and improving identity determination accuracy.
2Measurement precision
If apparatus-specific and material-specific collation parameters are used, then the accuracy of collation is improved, but the system complexity increases
Solution Approach 1:
The patent applies self-service by enabling the system to automatically select appropriate collation parameters based on the registered apparatus information, collation apparatus information, and material information. The system autonomously manages the complexity of multiple parameter sets by implementing automated parameter selection and management, eliminating the need for manual configuration and reducing operational burden while maintaining high collation accuracy.
Solution Approach 2:
The patent implements feedback mechanisms by using the registered apparatus information and material information to dynamically adjust and select collation parameters. The system continuously optimizes the collation process based on feedback from the specific apparatus and material characteristics, ensuring accurate identity determination while simplifying operation through automated adaptation.
3Reliability
If comprehensive apparatus and material information is registered, then the reliability of identity determination is improved, but the data management complexity increases
Solution Approach 1:
The patent applies universality by creating a unified data management framework that handles multiple types of information (apparatus information, material information, collation parameters) in an integrated manner. The system uses a universal parameter set structure that can accommodate different apparatus types and material types, allowing consistent management of diverse data while improving reliability through comprehensive information registration.
Solution Approach 2:
The patent implements preliminary action by pre-registering and organizing apparatus information, material information, and corresponding collation parameters in a structured database before actual collation operations. This preliminary organization of comprehensive data enables reliable identity determination during operation while simplifying data management through advance preparation and systematic structuring of information.
Data Source
AI summary
An identity determination apparatus includes a first storage unit that stores registration apparatus information used in a case where reference data obtained by imaging a portion of a surface of an object to be determined is registered, material information regarding the object which is a target for identity determination, collation apparatus information used in a case where collation data is acquired, and collation reference information used in collation in association with each other, a second storage unit that stores the registration apparatus information and the material information in association with reference data acquired in advance, a reception unit that receives collation data acquired from the object to be determined in a case where a determination process is performed, the material information, and the collation apparatus information, and a determination unit that reads out the collation reference information corresponding to the material information and the collation apparatus information which are received by the reception unit and the registration apparatus information to be specified by the collation apparatus information from the first storage unit, reads out the reference data corresponding to the registration apparatus information to be specified by the collation apparatus information, and the material information from the second storage unit, and collates the collation data received by the reception unit and the reference data read out from the second storage unit with each other using the read-out collation reference information to determine identity of the object to be determined.
