Cryptography and DRM: A study of digital copyright protection in the gaming industry

Abstract. This paper explores the role of cryptography and encryption technology in the evolution of digital rights management (DRM) in the gaming industry. A collection of guidelines, procedures, and instruments that control the appropriate use of digital content is collectively referred to as digital rights management (DRM). Cryptography plays a vital role in DRM by ensuring data privacy, authenticity, and integrity. The early stages of DRM in gaming involved physical disc-based methods, such as unique disc features and online activation. However, these methods faced challenges such as compatibility issues and unauthorized copying. Modern DRM techniques incorporate advanced cryptographic techniques and account-based DRM tied to user accounts. Cryptography in DRM secures the distribution and consumption of digital content by converting game data into an unreadable format, which can only be decrypted with a valid key. The paper also discusses the use of third-party DRM technologies like Denuvo, which employ robust encryption and obfuscation methods. However, third-party DRM can have performance impacts, inconvenience users, and lead to compatibility issues. The paper emphasizes the need for continuous refinement of DRM technologies to balance copyright protection and consumer rights in the evolving gaming industry.
