Split Key Decryption for Secure Lottery Game Access
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Current lottery and casino games lack innovative formats to maintain player interest, leading to high regulatory hurdles when introducing new games, and existing systems are not secure against unauthorized access to winning codes.
Innovation Solution
A system that combines a primary game, such as BEJEWELED, with a secondary game already approved by regulators, where the outcome of the secondary game is determined by a previously approved game, reducing regulatory efforts and using a ticket with a code to access outcomes stored on a server, enhancing security by requiring both ticket and server portions of a decryption key for access.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If a new game format is introduced to maintain player interest, then player engagement is improved, but regulatory approval complexity increases
Solution Approach 1:
The game system is divided into two distinct components: a primary game (already approved by regulators) and a secondary game (the new format). The primary game handles all regulatory compliance and outcome determination, while the secondary game provides entertainment value. This segmentation allows the new game format to be introduced without requiring fresh regulatory approval, as the outcome-determining primary game remains unchanged and approved.
2Reliability
If winning codes are stored on the server for later access, then game security is improved, but unauthorized access risk increases
Solution Approach 1:
The decryption key is split into two separate parts: one portion is provided to the player (e.g., on a ticket or card), and the other portion is securely stored on the server. To access the winning code, both parts are required simultaneously. This segmentation ensures that even if the server is compromised, attackers cannot access winning codes without the player-provided key portion, and vice versa.
3Ease of operation
If a code is printed on the ticket for access, then player convenience is improved, but security vulnerability increases
Solution Approach 1:
Instead of printing the complete decryption key or access code on the ticket, only a partial key portion is printed. The remaining portion is securely held by the server. This ensures that even if the printed ticket is intercepted or photographed, the intercepted code is useless without the server-held portion, thereby maintaining security while still providing player convenience through the printed access information.

AI summary
A system and method are provided for playing a game of chance. The game of chance may include, for example, a lottery-type game. A result of the game of chance is revealed to a player in another medium. In one example, the result is revealed during multiple game instances of one or more online games. In one example, the online game includes a game similar to the well-known game of BEJEWELED.
