Privacy-Preserving Responsible Gaming Systems

Responsible gaming aims at maintaining the integrity and sustainability of the gaming industry. However, The exchange of sensitive data, such as player and gaming related information, among different parties raises significant privacy concerns, and safeguarding privacy becomes a top priority consideration throughout the design and implementation of responsible gaming systems. In this paper, we introduce an innovative scheme that utilizes Oblivious Transfer (OT) and Private Set Intersection (PSI) protocols to address privacy concerns of responsible gaming systems. Our scheme proposes a system model that addresses privacy concerns related to player global limits and banned player list query and response, without requiring infrastructure changes, unlike blockchain-based solutions; Our proposed scheme not only addresses privacy concerns between the query user and the centralized database server but also mitigates privacy concerns between the query user and certificate authority (CA) by incorporating blind RSA signature scheme; Our proposed scheme achieves linear complexity in computation and communication, while remaining resilient against malicious adversaries under the random oracle model.
