IMAGE PROCESSING METHOD AND IMAGE INSPECTING METHOD

摘要

An image processing method and an image inspecting method are provided with highly general versatility for making it possible to efficiently and highly accurately prove the authentication of a digital image. The image processing method carries out a first morphologic operation for at least part of a digital image that may exist temporarily or continuously under possible falsification environment by using a predetermined structure element to process the digital image. The image inspecting method carries out a second morphologic operation for the processed digital image by using the same structure element as for the first morphologic operation. The morphologic operation has idempotence, and it is possible to detect if the image is subjected to falsification by judging an identity of the image before and after the second morphologic operation.
