Digital Right Management (DRM) is the system used to protect and manage digital copyrights. This technology is used by companies that distribute digital content, in order to avoid possible economic losses or misuse of the licenses in possession. These innovative technologies can be applied to content such as videos, books or music, and can even protect digital documents.
DRM systems have a specific operation, which can be identified in the following phases:
- Packaging and encryption, with a key, of the digital content.
- Storage of the encrypted package in a content server, guaranteeing its protection.
- Storage of the decryption key in a license server.
- Processing of payments made by the user.
- Download and/or reproduction of the content, offering the client a resource compatible with the platform on which it is stored.
- Decoding of the content through the player owned by the client (Windows Media, for example).
Thanks to this system, companies that own digital content licenses can ensure that, in order for a user to access this content, he/she is obliged to do so by legal means.
