Method for preventing unauthorized replication of optical data carrier on replication device, involves comparing specific identification symbol with specific reference identification symbol during specific identification symbol availability

摘要

The method involves testing a substrate of an optical data carrier (100) or a punch die on the availability or non-availability of a specific identification symbol (101) with a reading device. The specific identification symbol is read out with the reading device, where the specific identification symbol is compared with a specific reference identification symbol during availability of the specific identification symbol. The reference identification symbol is stored in a database. An independent claim is included for a system for preventing an unauthorized replication of an optical data carrier on a replication device.
