Abstract:
1. An image processing apparatus that reads a document to be copied with a reading unit and applies image processing to read image data, comprising: a radio wave receiving unit that is disposed in a traveling member of the reading unit and receives a radio wave transmitted from a radio tag when the document is read by the reading unit; a radio demodulation unit that demodulates the radio wave received by the radio wave receiving unit to obtain a demodulated signal; an identification unit that identifies identification information for the radio tag from the demodulated signal; a forgery judging unit that judges whether the document is a forgery prevention object according to the identification information identified by the identification unit; and a forgery preventing unit that, when the forgery judging unit judges that the document is the forgery prevention object, performs forgery prevention image processing on the read image data to prevent forgery of the read image data.
