Lottery Second-Chance Draw System Using Encryption Validation
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Lottery games are often discontinued due to top prizes being claimed, leaving players unable to win advertised top prizes, as tickets are sold out, leading to customer dissatisfaction and game discontinuation.
Innovation Solution
Implementing a secure 'second chance draw' system using unique validation codes on lottery tickets, where players can register their tickets online, with encryption algorithms (like MD5) to verify eligibility for subsequent draws, allowing players to participate in additional games without needing the physical ticket.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If lottery tickets are sold with top prizes assigned according to a predetermined prize structure, then players have an equal chance to win prizes, but top prizes may be claimed before all tickets are sold out, leading to customer dissatisfaction
Solution Approach 1:
The system performs preliminary actions by creating a reserved pool of top prizes that are set aside and not assigned to individual tickets at the time of printing. This allows the lottery to guarantee top prize availability throughout the game duration, as these reserved prizes will be awarded through the secondary drawing mechanism regardless of how many tickets are sold.
Solution Approach 2:
The prize structure is segmented into two separate mechanisms: (1) prizes assigned to specific tickets through the predetermined prize structure, and (2) reserved top prizes held in a pool for a secondary drawing. This segmentation allows the lottery to maintain both the original ticket-based prize distribution and the guaranteed availability of top prizes through the additional drawing opportunity.
2Reliability
If a second-chance draw system is implemented to guarantee top prize availability, then player interest is maintained throughout the game, but the system complexity increases with encryption algorithms and online registration
Solution Approach 1:
Instead of requiring players to submit physical tickets or complex verification data, the system uses a simplified copying mechanism where players enter a unique code printed on their ticket. This code is a simplified representation that can be easily transmitted online and verified through encryption, reducing the complexity of the verification process while maintaining security.
Solution Approach 2:
The system replaces manual ticket verification and physical ticket handling with electronic substitution. Players register their ticket codes online, and the system uses encryption algorithms to verify eligibility automatically. This substitution of mechanical verification processes with electronic and cryptographic methods streamlines the system while maintaining reliability.
3Ease of operation
If players must maintain possession of physical tickets to claim prizes in subsequent draws, then ticket validation is simplified, but players risk losing or damaging tickets
Solution Approach 1:
The system creates a digital copy of the ticket validation information by requiring players to submit their unique ticket codes for registration. Once registered, the system stores this information securely and uses encryption to verify eligibility. This allows players to claim prizes without needing to physically possess the original ticket, eliminating the risk of loss or damage while maintaining validation security through the registered code.

AI summary
A computer-implemented system and method for providing a lottery game includes providing players with a unique validation code for each desired play of a lottery game. A first encryption code is generated for each validation code and stored so that the first encryption code and algorithm are present only as electronic data in the computer system and are not provided to the players. Players submit their respective unique validation code for registration in the lottery game and the computer system applies the algorithm to each code submitted by a player to create a second encryption code for each unique validation code. The computer system compares the second encryption code with a record of the first encryption codes to determine whether a match exists between the second encryption code and one of the first encryption codes.
