Abstract:
Data representing a sheet of document is obtained. Then, an area where it is possible to obtain a paper fingerprint from the obtained data representing the sheet of document is determined, and a paper fingerprint intensity of the sheet of document is calculated based on a number of areas of one or more paper fingerprint obtaining patterns allocated in the area where it is possible to obtain a paper fingerprint. Furthermore, a result of the calculation is reported to a user.
