Digital rights management (DRM) is the use of technical controls to manage who can access digital content and what they can do with it. Depending on the system, those controls may restrict playback, copying, or other uses. DRM is not copyright ownership or copyright law; it is technology used to manage or enforce conditions around digital works.
What does DRM mean?
DRM is a broad term for technologies associated with digital content and devices that control access to or use of protected works. 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.” W3C’s 2016 EME factsheet uses that wording.
In practice, a DRM system may check whether a user or device is authorized, then allow or restrict particular operations. The rules differ by system; there is no single universal DRM mechanism. DRM appears in some ebooks, movies, games, software, and streaming media, but not every digital product uses it.

Many DRM systems use encryption together with access controls or license checks. A device or application may need authorization before it can decrypt or play protected content. Encryption is common, but DRM and encryption are not synonyms: protection approaches can also identify or trace content without encrypting it.

Encryption and access control
Encryption makes content unreadable without the means to decrypt it. Access controls determine whether a user, account, application, or device is permitted to access it. Systems may combine these methods, with permissions defining what can happen after access is granted.
Watermarking and fingerprinting
Watermarking embeds identifying information in content, while fingerprinting creates a way to recognize a work. These approaches can help identify or trace content rather than prevent access through encryption. ISO/IEC 23078-1:2024, which covers digital publishing protection technologies, includes approaches such as watermarking and fingerprinting that do not rely on encryption. They may be used alongside other protections; the categories are not always mutually exclusive.

Example: protected video in a browser
A browser can use the W3C Encrypted Media Extensions (EME) API to communicate with DRM software so that encrypted video can be played. EME is an interface for connecting web playback with a DRM agent; it is not itself DRM and does not require a DRM system. As W3C puts it, “EME allows a method of playback of encrypted content on the Web but W3C does not make the DRM technology nor require it.” The W3C factsheet explains the distinction.

Does DRM determine copyright ownership?
No. DRM is a technical way of managing access to or use of content; it does not create copyright ownership or replace copyright law. Copyright rules, permissions, limitations, and defenses are legal matters distinct from the technical controls a system applies.

Is DRM circumvention illegal?
The answer depends on the jurisdiction. In the United States, the Digital Millennium Copyright Act (DMCA) includes rules about technological protection measures. Under 17 U.S.C. §1201 in the 2024 edition, circumvention includes decrypting an encrypted work or otherwise avoiding, bypassing, removing, deactivating, or impairing a technological measure without authority. The statute describes an access-control measure as one that, in its ordinary operation, requires authorized information, a process, or treatment to gain access to a protected work.
The U.S. Copyright Office gives examples including decrypting a DVD containing a copyrighted film and 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 are U.S.-specific rules, not a worldwide statement about circumvention; other jurisdictions have their own laws and exceptions. See the Copyright Office’s Section 1201 FAQ and its overview of the DMCA.
