OPTICAL DISC AUTHENTICATION BY INTERFEROMETRIC FINGERPRINTING |
摘要 |
<p>Authentication of discs occurs by the use of interferometric authentication data. Such authentication data of a data disc is generated based on an interference pattern associated with thickness variations of a material layer on the disc. The interference pattern represents a unique fingerprint that can be used for authentication of individual discs.</p> |
