摘要

An anti-forgery certificate for identifying the truth of an object by verifying a micro-code and a verification code is provided. The verification code and the corresponding micro-code for identifying the truth of an object are both printed on the surface of the anti-forgery certificate, the micro-code consists of a plurality of micro-image cells, every kind of combination of the micro-image cells corresponds to a micro-code and forms a mini-image which is invisible by naked eyes. The micro-code can be decoded to produce an unique information code which is the same with the verification code printed on the surface of the anti-forgery certificate.
