A FALSE-PROOF CERTIFICATE AND SYSTEM, AND A METHOD FOR IDENTIFYING THE TRUE OR THE FALSE OF AN ITEM

摘要

The invention discloses a false-proof certificate with a printed micrographic code, a false-proof system based on it, and a method for identifying the true or the false of an item. The false-proof certificate includes the micrographic code printed on its surface and representing the item to be identified. The identifying method comprises the steps of: an optical unit obtains an optical image of a surface of the false-proof certificate associated with the item to be identified, and an image sensor transforms the optical image into a digital image（S3）, an image identifying and processing unit detects whether the micrographic code is presented in the digital image（S4）, if there is, the image identifying and processing unit picks up the micrographic code and decodes it into a verification code corresponding uniquely to it（S5）, and a control unit looks up an item information corresponding to the verification code in a map which establishes a unique corresponding relation between the item information and its verification code and is pre-stored in a memory unit（S6）, if find it, outputs it, and determines whether the item to be identified is false by means of it（S7）. The false-proof system includes the false-proof certificate and various units used in the method. The false-proof system and method of the invention identify items quickly, can carries out a great much of identification during a short period.
