Digital rights management (DRM)

DRM systems encrypt the content, making it unreadable without the appropriate decryption key. Only authorized users with valid licenses can decrypt and access the protected content.

DRM platforms manage the creation and distribution of digital licenses that grant users access to the encrypted content. The license specifies the permissions and constraints, such as duration of access, allowed devices, etc.

DRM enables copyright holders to define and enforce access policies - who can access the content, for how long, on which devices, etc. Unauthorized users are prevented from accessing the protected files.

DRM places restrictions on copying, printing, editing and sharing of the content. This makes it difficult for users to create and distribute unauthorized copies.

Some DRM solutions embed imperceptible watermarks into the content containing user identity and transaction details. This allows tracing the source of piracy if unauthorized copies are found.

For streaming media, DRM systems require periodic online authentication of user licenses. This prevents access if the license is revoked or expired, limiting the risk of piracy.

By making it harder and riskier to access and share unauthorized copies, DRM has proven effective in curbing rampant piracy and protecting revenues for copyright holders.
