激光指纹术

LASER FINGERPRINT TECHNOLOGY

本文介绍一种信息保护技术。整个技术内容都设在记录介质上，每一个独立的信息载体均拥有一副特异的由ＹＡＧ激光束刻蚀的激光指纹。该指纹被磁编码。

This paper introduces a technology for information.All the technique is on the recording medium.Each individual information carrier is imprinted with a unique “fingerprint” which is marked by a YAG laser beam.It is encoded magnetically.The encryption ensures a high level of security for information.
