Portable Device Transaction Data Integration for Fraud Prevention
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Current transaction systems lack effective methods to incorporate time and location data for secure and efficient point-of-sale transactions, particularly in preventing fraud and ensuring the uniqueness of transaction data.
Innovation Solution
The integration of portable electronic devices that obtain and process transaction data, including location coordinates and date/time stamps, to generate decodable optical indicia or wireless transmissions for use in processing transactions, which are then verified by point-of-sale systems to reduce fraud and ensure data uniqueness.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If traditional transaction systems are used without time and location data, then transaction processing is simple and fast, but fraud prevention capability is weak and transaction uniqueness cannot be ensured
Solution Approach 1:
The system performs preliminary actions by obtaining time and location data before the transaction is processed. The portable electronic device captures the current time stamp and location coordinates prior to generating the surrogate account number, ensuring that unique identifying information is embedded in advance. This preliminary data collection enhances fraud prevention without significantly complicating the overall transaction flow.
Solution Approach 2:
The patent introduces an intermediary mechanism by using a portable electronic device as a mediator between the user and the transaction system. This device automatically collects time and location data, generates the surrogate account number with embedded temporal and spatial information, and transmits it to the point-of-sale system. This intermediary approach shields users from direct complexity while enhancing security.
2Reliability
If surrogate account numbers are made unique by adding expiry date and time, then transaction uniqueness is improved, but data processing complexity increases
Solution Approach 1:
The patent merges multiple data elements (surrogate account number, time stamp, location coordinates) into a single integrated data structure. The portable electronic device combines these elements to generate one comprehensive surrogate account number that inherently contains uniqueness information. This merging approach ensures transaction uniqueness while avoiding the need for separate processing of multiple independent data fields.
Solution Approach 2:
The system changes the parameters of the surrogate account number by embedding time and location information directly into it. Instead of treating time and location as separate validation fields, the patent transforms them into integral components of the account number itself. This parameter integration simplifies processing by allowing the entire unique identifier to be transmitted and validated as a single unit.
3Reliability
If time and location data are collected and processed, then transaction security is enhanced, but processing time and system resource usage increase
Solution Approach 1:
The portable electronic device performs self-service by automatically collecting time and location data without requiring user input or manual intervention. The device's operating system and sensors autonomously provide the necessary temporal and spatial information, eliminating the time cost of manual data entry while enhancing security through automated data capture.
Solution Approach 2:
The patent replaces manual or mechanical data collection methods with automated electronic systems. Instead of users providing location and time information through forms or verbal input, the system uses the portable device's built-in sensors, GPS, and clock to automatically capture this data. This substitution significantly reduces processing time while maintaining enhanced security.
Data Source
AI summary
A method includes obtaining data from a portable electronic device in which the data regards information obtained using the portable electronic regarding the transaction, and information obtained using the portable electronic regarding at least one of a physical location of the portable electronic device when obtaining the information regarding the transaction and the time of the day when obtaining the information regarding the transaction, and processing the transaction based on the data regarding the information regarding the transaction and the at least one of the information regarding the physical location of the portable electronic device when obtaining the information regarding the transaction and the time of the day when obtaining the information regarding the transaction. The method may be employed in a point-of-sale transaction for the purchase of products at checkout.
