Those controls may include encryption, access checks, or license verification; some content-protection approaches instead use watermarks or fingerprints to identify or trace copies. DRM is not copyright ownership or copyright law—it is a technical way of managing or enforcing conditions around digital works.
What does DRM mean?
DRM stands for digital rights management. The World Wide Web Consortium (W3C) describes DRM systems as “access control technologies that are used to constrain access to or use of proprietary hardware and copyrighted works.” In practical terms, DRM refers to technology associated with digital content or devices that can determine who may access something and which operations are permitted. The controls vary by system; there is no single universal DRM mechanism.

DRM may be used with books, movies, video games, software, or streaming media, but that does not mean every digital product uses it.

A DRM system applies technical rules to content or access. For example, a system might encrypt a video and require an authorized playback process, or check a license before allowing a particular use. The exact permissions depend on the implementation. A DRM label alone does not establish whether a person can download, copy, print, transfer, or keep content; those details depend on the specific service, format, and license.

Encryption and access controls
Encryption can make content unreadable without the required key or authorized process. An access-control system may also check credentials, a license, or another authorization before permitting use. Encryption is common in DRM, but it is not the whole definition.
Watermarking and fingerprinting
Some content-protection approaches identify or trace content rather than preventing access through encryption. Watermarking can embed identifying information, while fingerprinting can help recognize a work or copy. ISO/IEC 23078-1:2024, which addresses digital-publishing protection technologies, includes approaches that do not rely on encryption. These methods can be used alongside other controls; they are not necessarily alternatives in every system.

How DRM works in browser video
For web video, the W3C Encrypted Media Extensions (EME) specification provides a way for a browser to communicate with DRM agent software so encrypted video can be played. EME is an interface for communication and playback integration, not a DRM system itself. The W3C explains that EME “allows a method of playback of encrypted content on the Web but W3C does not make the DRM technology nor require it.” A browser API can therefore connect playback to a protection system without being that system or requiring every site to use DRM.
Is DRM the same as copyright?
No. Copyright law concerns legal rights in works; DRM is technology used to control or manage access and use. DRM does not create copyright ownership, and the existence of a technical restriction does not by itself explain who owns a work or what copyright law permits. Copyright rules, exceptions, and anti-circumvention rules are distinct legal questions.

What does U.S. law say about DRM?
In the United States, section 1201 of the Digital Millennium Copyright Act addresses circumvention of certain technological measures. The statute defines circumvention to include decrypting an encrypted work or otherwise avoiding, bypassing, removing, deactivating, or impairing a technological measure without authority. An access-control measure, as defined in the statute, ordinarily requires authorized information, a process, or treatment to gain access to a protected work.
The U.S. Copyright Office gives examples such as decrypting a DVD containing a copyrighted film or bypassing a password control to access a subscription video-streaming service. Section 1201 also has a rulemaking process for temporary exemptions. It states that it does not affect other copyright rights, limitations, or defenses, including fair use. These points describe U.S. law, not a worldwide rule; other jurisdictions may treat DRM and circumvention differently, and legal rules can change.

It means some technical mechanism is being used to manage or constrain access to, or use of, the content. The phrase does not tell you exactly which actions are allowed. Check the applicable service terms, license, or format details for whether the content can be accessed offline, transferred between devices, copied, or retained after a subscription ends.
