The false alteration verification methodological computer of the image file generation method and the image file for false alteration

摘要

As for this invention, being the image file formation method for false alteration verification where it can judge whether or not the fake of the image file which is formed by device such as digital camera and scanner you altered, and something regarding the false alteration verification method of the image file, as for the image file formation method for false alteration verification due to this invention, step and the above-mentioned 2 dimensional bar-code which form 2 dimensional bar-code from step, the above-mentioned side check logic, vertical check logic, and the check logic classified by territory which form side check logic, vertical check logic, and the check logic classified by territory from step and the above-mentioned bit map which form the bit map of the image file insertIncluding the step which forms the image file for false alteration verification which is done, it becomes, as for false alteration verification method of the image file due to this invention, forming the bit map of the image file for false alteration verification where 2 dimensional bar-code is inserted, from the above-mentioned bit map 1st side check logic, 1st vertical check logic, from step and the above-mentioned 2 dimensional bar-code which form the check logic of the classified by 1st territory 2nd side check logic, 2nd vertical check logic, and step and the above-mentioned 1st side check logic which form the check logic of the classified by 2nd territory and 2nd side check logic and the above-mentioned 1st vertical check logicWith 2nd vertical check logic and check logic of the classified by above-mentioned 1st territory and including the step which compares the check logic of the classified by 2nd territory mutually, it becomes.
