[ For example, the format data FD1 may be different for each company (or subject) that transmits the fax data, so the format data FD1 may be used as data that can identify the fax (or fax device) used by the company or the company .

3 and 4, the position of the specific line LINE50 of the true fax image data FI1 has been changed to the position of the specific line LINE51 of the fax image data FI2 in the process of falsification or modulation.

For example, FID2 refers to the physical (or mechanical) attribute data of the second originating fax 220 and may be the only value that can distinguish the second originating fax 220 from other originating faxes. For example, FID2 may be the product serial number of the second originating fax 220.

Referring to FIG. 4, it is assumed that DPI1 is changed to DPI2 and FD1 is changed to FD2 in the course of falsification or modulation of the first fax data FDATA1.

Each of DPI2 and FD2 may be data having a unique value capable of distinguishing the second fax data FDATA2 from other fax data. For example, at least one of DPI2 and FD2 may mean transmission format data of the second fax data FDATA2.
