METHOD OF PROTECTING FORGERY/ALTERATION IN DIGITAL IMAGE CREATION AND COMPUTER-READABLE MEDIUM HAVING THEREON PROGRAM PERFORMING FUNCTION EMBODYING THE SAME

摘要

A method for preventing the forgery/alteration when generating an image and a recording medium in which a program for realizing the method is recorded are provided to grasp whether a digitalized image is forged or altered, easily when a person distributes or uses the digitalized image. A security file system is set up(S110). Image data about a document is obtained based on the set security file system(S120). The original document image is generated and stored(S130). Forgery/alteration verification information is inserted into the corresponding original document image(S140). A document image is generated and stored based on the forgery/alteration verification information(S150). The generated document image is transmitted to an external storage unit(S160).
