The invention provides a local grain anti-counterfeiting print, fiber grains are directly fabricated at a local region on the print, randomly distributed characteristic information of fiber is scanned, collected and stored in a database of a computer anti-counterfeiting inquiry system connected to a telephone network or/and the Internet for the masses to check truth; the print can be produced by utilizing fibreless grain materials including current standard paper, films and the like, can avoid specific paper making and film making, lightens the influence of the fiber on the aesthetic sensibility of the print, and can prevent a fake producer from continuing to use the print after uncovering the print.
