Claim One:
1. A method for printing stock anti-counterfeiting by means of a feature image, characterized in comprising steps of: obtaining a feature code for identifying a printing stock by recognizing a first feature of the feature image printed on the printing stock, and correspondingly searching for pre-recorded first anti-counterfeiting information of the printing stock in a database by using the feature code; obtaining second anti-counterfeiting information of the printing stock by recognizing a second feature of the feature image printed on the printing stock; and comparing whether a similarity between the second anti-counterfeiting information and the first anti-counterfeiting information reaches a first match threshold value through a manual comparing method or an intelligent device comparing method, wherein if the similarity is higher than the first match threshold value, the printing stock is true, else if the similarity is lower than the first match threshold value, the printing stock is false, wherein the first anti-counterfeiting information is embodied as a distinguishable material feature of the printing stock in a feature image region or features of color, shape and position of an image printed in the feature image region.
