<p>A driver's license imaging section comprises a structure that can capture a driver's license's watermarks both from either its obverse or reverse. And a driver's license imaging controller orders the driver's license imaging section to capture the driver's license's a watermark from its obverse. Using this result, an authenticity judging section judges the driver's license's authenticity. Then, if the driver's license is back-watermarked type, it is recognized as not authentic, when the driver's license imaging controller orders the driver's license imaging section to capture the driver's license's a watermark from its reverse. Using this result, the authenticity judger judges if the driver's license is authentic or not. In this way, a legal back-watermarked type driver's license is judged authentic. Consequently, a driver's license's authenticity can be judged properly, no matter whether the driver's license is face-watermarked type or back-watermarked type. <IMAGE></p> |
