ABSTRACT:
A method for authenticating an interactive optical disk, wherein first content is stored on the interactive optical disk for reproduction by a reproducing system, the method comprising: transmitting a first request to a content server to access second content from the content server based on enhanced navigation data recorded on the interactive optical disk; and authenticating identity of the interactive optical disk with the content server based on authentication data provided by the reproducing system, when the first request indicates that authentication is required.
