1. An image processing apparatus having a copy function, the image processing apparatus comprising:
a memory that stores a program; and
a processor that executes the program to perform:
obtaining a scanned image by scanning a copy-target printed material;
extracting embedded information from the scanned image;
generating an image to be printed based on the scanned image; and
performing print processing using the image to be printed, wherein the generating comprises:
determining whether or not a document ID indicated by the extracted embedded information is valid;
removing the embedded information from the scanned image;
determining, by comparing pixel values of the scanned image from which the embedded information has been removed and pixel values of an image obtained by performing a rendering process for electronic document data associated with the document ID, whether or not the copy-target printed material has been falsified, wherein the electronic document data is managed along with information indicating that the contents thereof are authentic; and
generating, in a case where it is determined that the document ID is valid and the copy-target printed material has not been falsified, the image to be printed that is the scanned image to which information indicating being a copied material of an authentic document is added.
