Lottery Seed Generation via Multi-Party Fragment Combination
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Current security systems for instant lottery ticket games require a second shuffle step in Keyed Dual Security, which can lead to issues like unusable tickets and difficulties in reconstructing ticket information, and there is a need for a system with a single shuffle using a secret final game generation seed that is transparently combined from multiple key or seed fragments.
Innovation Solution
A method is provided to securely generate a lottery game by forming a final game generation seed from multiple seed fragments from different parties, ensuring that no single party can create the final seed without the others' consent, and this seed is used to generate game entries, with transparency and auditing to verify the contribution of each party's seed.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If a second shuffle step is added in Keyed Dual Security, then security is improved, but ticket usability and reconstruction capability deteriorate
Solution Approach 1:
The patent extracts the harmful second shuffle step from the Keyed Dual Security system while retaining the beneficial multi-party seed combination mechanism. By removing the redundant shuffle operation that causes ticket usability issues, the system maintains security through cryptographic seed combination without the operational drawbacks of multiple shuffling steps.
Solution Approach 2:
The patent segments the seed generation process into multiple independent seed fragments held by different parties, which are then combined through a deterministic cryptographic function. This segmentation allows security to be distributed across multiple parties without requiring multiple shuffling operations, thus avoiding the ticket usability problems caused by traditional dual-security shuffling.
2Reliability
If a second shuffle step is added in Keyed Dual Security, then security is improved, but system complexity increases
Solution Approach 1:
The patent removes the redundant second shuffle step from the Keyed Dual Security system, directly reducing system complexity. By extracting this unnecessary operational step while maintaining the core security mechanism through multi-party seed combination, the system achieves the same security level with fewer operational components and less complexity.
Solution Approach 2:
The patent merges the security function into a single deterministic seed combination operation rather than requiring separate shuffle steps. By combining multiple seed fragments through a cryptographic function in one operation, the system achieves enhanced security without the additional complexity of multiple sequential shuffle operations.
3Reliability
If multiple seed fragments are combined from different parties, then security and transparency are improved, but the process complexity increases
Solution Approach 1:
The patent introduces a trusted intermediary or predetermined cryptographic function as a mediator that combines multiple seed fragments from different parties. This intermediary mechanism provides a standardized, transparent combining process that enhances security through multi-party involvement while maintaining manageable process complexity through the use of established cryptographic protocols.
Solution Approach 2:
The patent employs a universal cryptographic combining function that can process seed fragments from any number of parties in a standardized manner. This multi-functional approach allows the same combining mechanism to serve security, transparency, and auditability purposes simultaneously, improving security without proportionally increasing process complexity.

AI summary
Methods and systems for securely generating lottery games are presented. A final game generation seed number is formed from multiple seed numbers from multiple and differing parties such that no one party has the ability to create the final seed number without the other parties' consent or knowledge. Since the final seed number is required by the software that governs the distribution of prizes within a game and is therefore required to produce valid game data, no one entity would have enough information to determine the location of a winning prize. This creates an environment of transparency such that all parties must agree on the terms that result in the formation of the final seed number from the individual seed number fragments in order to produce a game.
