PURPOSE:To identify with high safety and exactness by composing a figure train by converting a displayed random number according to a decided rule without using any specified personal identification number CONSTITUTION:This system is composed of a figure input device equipped with a display part (display panel) 1 to display the random number and ten keys 2 or the like, circuit to collate whether figures inputted by the ten keys 2 are the figure train reprogrammed to the displayed figures by a regulated conversion pattern or not, and part to output the collated result to the outside. Namely, any specified personal identification number is not provided. A user reconstitutes the figures according to a regulated converting method based on the displayed random number and inputs this to the system. Then, by collating whether the inputted figures can be obtained by converting the displayed random number according to the regulated method or not, the identity of the input person is checked. |
