Paper Abstract

This paper presents a new method of encrypting the laser holographic label for anti-counterfeiting. It is called 'random stripes intervening method'. This method has been successfully used in encrypting the holographic label for anti-counterfeiting. The features of this method are that it is almost impossible to imitate the labels after using this method, and it would not cause any extra price to the product, and it could be sued in the 'front line' of anti- counterfeiting.
