Lottery Transaction Profile Linking for Ownership Verification
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Current lottery systems lack an efficient method to link and manage transaction information across various events, making it difficult to investigate prize claims and verify ticket ownership, especially for lost or found tickets.
Innovation Solution
A method and system for managing transaction information in a lottery system by using unique identifiers (uTIDs) to link transactions of predefined types, such as validation, free wager, exchange, repurchase, and promotion, allowing for the creation of a transaction profile that associates a current transaction with previous related transactions, facilitating prize investigations.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Loss of information
If transaction information is stored in a database without linking mechanisms, then data storage is simple, but it becomes difficult to retrieve and verify ticket ownership information for prize claims
Solution Approach 1:
The system performs preliminary action by automatically linking transactions to tickets at the time of purchase and validation, creating transaction profiles in advance. This eliminates the need for complex manual tracing during prize claims, as all transaction history is pre-associated with the ticket through unique identifiers and link-back event types.
Solution Approach 2:
The patent introduces an intermediary mechanism - the transaction linking system using unique transaction identifiers (uTIDs) and link-back event types - that mediates between raw transaction data and ownership verification needs. This intermediary layer automatically connects transactions to tickets without requiring direct complex queries during claim investigations.
2Productivity
If all transaction details are manually traced during prize investigations, then complete information can be obtained, but the investigation process becomes time-consuming and inefficient
Solution Approach 1:
Transaction profiles are created and maintained in advance with all relevant transaction links already established. During prize investigations, investigators can immediately access pre-computed transaction histories without performing manual tracing, significantly reducing investigation time while maintaining complete information accuracy.
Solution Approach 2:
The system provides feedback by automatically generating and maintaining transaction profiles that reflect the complete transaction history. This feedback mechanism ensures investigators receive up-to-date, accurate information without manual intervention, improving productivity while minimizing time loss.
3Reliability
If a comprehensive transaction profile is created for every ticket, then ownership verification is accurate, but the system complexity and data storage requirements increase
Solution Approach 1:
The system segments transaction information by creating structured transaction profiles with standardized link-back event types (purchase, validation, exchange, repurchase, promotion). This segmentation organizes complex data into manageable, queryable units, maintaining verification accuracy while reducing system complexity through consistent data structuring.
Solution Approach 2:
The patent changes parameters by using standardized event type classifications and unique identifier systems. This parameter standardization transforms complex transaction data into a structured format that is easier to manage and query, maintaining reliability while reducing the operational complexity of the profile management system.
4Loss of information
If transaction linking is implemented for all event types, then complete transaction history is available, but the data processing and storage requirements increase
Solution Approach 1:
The system extracts only the essential linking information (unique transaction identifiers and event types) needed for ownership verification, rather than storing complete transaction details for every event. This extraction approach maintains complete transaction history availability while reducing data storage requirements by focusing on critical linking data.
Solution Approach 2:
Transaction profiles are preliminarily constructed with essential linking information at the time of transactions. This preliminary action ensures complete transaction history is captured without requiring storage of all raw transaction data, optimizing the balance between information completeness and storage efficiency.
Data Source
AI summary
Interactions with the lottery system may be stored to a central database or data store. The transactions stored in the lottery system may represent interactions with the lottery system, such as purchasing of tickets and validating tickets. The lottery system may link a current transaction with a previous transaction, allowing a transaction profile of a ticket to be generated. The transaction profile information may be used for various purposes including supporting an investigation.
