Piracy prevention is the set of technical and procedural measures that deter and detect unauthorised copying, distribution, and use of digital content. It encompasses encryption, licensing, access control, watermarking, and tamper resistance, typically delivered through digital rights management systems. Its objective is to enforce usage rights while balancing legitimate user access and interoperability.

- Techniques combine content encryption with licence servers that gate decryption keys to authorised devices, forensic watermarking to trace leaks, and tamper-resistant clients to resist circumvention. Effective schemes must withstand the analogue hole and key extraction while not degrading legitimate playback, making piracy prevention an ongoing arms race between rights holders and circumvention efforts.
