 |
Overview |
|
| DRM (Digital Rights Management) is technology used to protect multimedia content delivered via streaming or download. To prevent piracy, the multimedia content provider, or service provider, encrypts the content through a packaging process. When the user replays the multimedia content, it checks the user's privileges and validity, and after the user has "passed," issues a license key to decrypt the content. |

| Overview |
|
| Media authentication is technology that allows only authorized users to play multimedia content. This is done by assigning access privileges for streaming multimedia content. |
| If an unauthorized user attempts to access the content, using a path attained through a source file of a Web browser or some other means, the authentication technologyverifies that the user's authentication privilege has changed. |
| It then limits the user's access to the content, satisfying the needs both of user management and content security. |
