A device-independent authentication system and method allows a parent to control access to selected versions of multimedia content to prevent some viewers from viewing inappropriate material. The multimedia content may be, for example, one or more different versions of the same movie or game distributed on a disk, or a movie ordered from a service provider. The system and method authenticates users based on authentication data provided by the parent and on a content based characteristic associated with the selected content. Successful authentication permits a person to view the desired content, while unsuccessful authentication prevents viewing the desired content. |
