Secured Optical Information Carrier, and Data Encryption Method and Apparatus for Recording Data in the Optical Information Carrier |
摘要 |
An optical information carrier and method and apparatus for securing the carrier are presented. The optical information carrier comprises a recording medium for recording data therein in the form of a first pattern of spaced-apart recorded regions configured to provide a first optical response to incident light, and comprises a pattern of spaced-apart regions configured to respond to incident light by a second optical response pattern. Distribution of the spaced-apart regions forming the second optical response pattern is indicative of an individual and identifiable carrier specific signature.
