AI Technical Summary

Technical Problem

Existing border inspection equipment suffers from problems such as a single verification dimension, lack of quantitative evaluation mechanism, lagging rule iteration, and high false alarm rate in electronic passport chip verification, making it difficult to identify counterfeit chips and resulting in low clearance efficiency.

Method used

The method employs a multi-dimensional rule-based intelligent scoring approach. By reading chip version identification information and calling multi-level verification rule sets, it performs multi-dimensional comparisons and weighted scoring. Combined with a blockchain distributed knowledge base and intelligent analysis model, it automatically updates and optimizes verification rules, generates a comprehensive verification score, and triggers corresponding warnings.

Benefits of technology

It enables rapid and accurate adaptation to different chip versions, improves the accuracy of genuine and counterfeit identification, reduces the false alarm rate, ensures the timeliness of rules and data security, and enhances customs clearance efficiency and passenger experience.

Abstract

The invention relates to an electronic passport chip verification method based on multi-dimensional rule intelligent score assignment, and belongs to the technical field of frontier inspection. The method comprises the steps that version identification information of an electronic passport chip is read, and a corresponding multi-level verification rule set is called from a pre-constructed chip rule knowledge base according to the version identification information and comprises a chip attribute rule, a storage data rule and a safety verification rule; inputting the collected chip data into a multi-dimensional rule intelligent analysis model, performing multi-dimensional comparison with a reference rule mode of a chip of the same version, performing weighted score assignment based on a preset weight, and generating a comprehensive verification score, thereby triggering early warning of different levels; a background optimization engine is integrated, high-frequency false alarm rules are automatically extracted by analyzing alarm logs, uncovered abnormal modes are mined to generate new rules, and a rule set is continuously optimized through shadow testing. Accurate and efficient verification of the electronic passport chip is realized.
