ABSTRACT:
An image forming apparatus includes a paper fiber reading unit that reads fiber properties of a paper sheet; an encryption unit that encrypts at least a part of an input image based on the fiber properties read by the paper fiber reading unit; and a printing unit that prints an encrypted image portion encrypted by the encryption unit and an image including information representing the fiber properties read by the paper fiber reading unit on the paper sheet whose fiber properties are read by the paper fiber reading unit.
