Abstract
An information medium recognition device for recognizing an information medium such as a handwritten signature inputted by performing an offline input operation. The information medium recognition device is provided with a detection portion for scanning the information medium in different scanning directions and for detecting a stroke density corresponding to each of the scanning directions, an inference portion for converting the stroke density into a compressed fuzzy density by performing a fuzzy inference process on the stroke density corresponding to each scanning direction, which is detected by the detection portion, and a judgement portion for judging from the fuzzy density corresponding to each scanning direction whether or not the information medium is genuine. Thereby, the information medium recognition device has an excellent effect in that the genuineness of the information medium such as a handwritten signature can be accurately recognized and judged on the basis of data obtained as the result of the fuzzy inference processing performed by the inference portion.
