Abstract: Content privacy and unauthorized access to copyrighted digital media content are common in the dynamic, fast-paced digitalized media marketplace. Cryptographic methods are the foundation of modern digital media security, and they must ensure the security, integrity, and authenticity of digital media data. This article analyses cryptographic methods that are used to protect digital media content. The paper reviews the main cryptographic concepts, such as symmetric cryptography, asymmetric cryptography, hash functions, and digital signatures. The paper also discusses some popular approaches: encryption, Digital Rights Management (DRM), watermarking, and solutions based on blockchain. Finally, we highlight implementation challenges such as key management and scalability and identify emerging trends such as quantum-safe cryptography and privacy-preserving techniques. By presenting the current research results and discussing the directions for the future, the study aims to pave the way for secure, efficient, and robust cryptographic solutions for digital media protection, leading to sustainable development, innovation, and secure communication of digital content among users.
