Transport Validator Checks Denial Attributes Before False Denials
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing passenger transport systems with open payment ticket media suffer from reduced usability and reliability due to incorrect inclusion of authorized electronic medium identifiers in denial data sets, leading to unauthorized denial of transport vehicle use.
Innovation Solution
A validator device that includes a reader module, data memory for a denial data set containing denied electronic medium identifiers with assigned attributes, and a verification arrangement to check denial criteria before denying system access, ensuring authorized users can use the transport system.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If a validator device uses a denial data set to block unauthorized electronic medium identifiers, then security is improved, but reliability deteriorates due to incorrect inclusion of authorized identifiers
Solution Approach 1:
The validation process is segmented into multiple independent checks: first checking the denial data set for blocked identifiers, then checking the allow data set for permitted identifiers, and finally verifying against the list of all possible identifiers. This segmentation allows the system to maintain security while reducing false denials through comprehensive multi-stage validation.
Solution Approach 2:
The system implements feedback mechanisms where validation results are recorded and fed back into the denial and allow data sets. Incorrect denials are identified through feedback from validation attempts, and the data sets are updated accordingly to prevent future false denials while maintaining security against actual unauthorized access.
2Reliability
If the validator device performs comprehensive validation checks, then reliability is improved, but device complexity increases
Solution Approach 1:
The system performs preliminary actions by pre-loading and maintaining sorted data sets of denied and allowed electronic medium identifiers in the validator device. This preliminary preparation enables fast validation through binary search algorithms, reducing the complexity of real-time validation while maintaining high reliability through comprehensive pre-checked data.
Solution Approach 2:
The system creates and maintains copies of the electronic medium identifier lists in the validator device's memory. These local copies of the denial data set, allow data set, and complete identifier list enable rapid validation without requiring complex real-time communication or processing, simplifying the validation process while maintaining accuracy.
3Reliability
If the system maintains comprehensive data sets for validation, then reliability is improved, but loss of information increases due to incorrect data inclusion
Solution Approach 1:
The data sets in the validator device are made dynamic and can be updated in real-time based on validation results and feedback. When incorrect denials are detected, the system dynamically updates the denial and allow data sets to remove false positives and add correct entries, thereby maintaining reliability while preventing information loss from persistent incorrect data.
Solution Approach 2:
The validation system performs self-service by automatically detecting and correcting incorrect data in its own data sets. Through self-validation and feedback mechanisms, the system identifies and removes false positives from the denial and allow data sets without external intervention, maintaining information accuracy and reliability autonomously.

AI summary
A validator device for a passenger transportation system includes a reader module configured to detect an electronic medium identifier of an open payment ticket medium. Data memory of the validator device stores a denial data set containing at least one denied electronic medium identifier and at least one denial attribute assigned to the denied electronic medium identifier. A comparator module identifies a denied electronic medium identifier from the at least one denied electronic medium identifier contained in the denial data set by comparing the detected electronic medium identifier with the at least one denied electronic medium identifier. A verification module checks, upon identification of a denied electronic medium identifier, whether the at least one denial attribute assigned to the identified denied electronic medium identifier satisfies predetermined denial criterion. An output module is configured to permit a use of the passenger transportation system responsive to a determination by the verification module.
