The present invention is related to a method for generating an image file for forgery verification and a method for forgery verification. A method for generating an image file for forgery verification according to the present invention consists of a generating a bit map of the image file, a generating a horizontal check logic, a vertical check logic, and a check logic of each region from the bit map, a generating a two-dimensional bar code from the horizontal check logic, the vertical check logic, and the check logic of each region, and a generating an image file for forgery verification into which the two-dimensional bar code is inserted. A method for forgery verification according to the present invention consists of a generating a first horizontal check logic, a first vertical check logic, and a first check logic of each region from the bit map by generating a bit map of an image file for forgery verification into which a two-dimensional bar code is inserted, a generating a second horizontal check logic, a second vertical check logic, and a second check logic of each region from the two-dimensional bar code, and a comparing the first and the second horizontal check logics, the first and the second vertical check logics, and the first and the second check logics of each region.
