Valuable cipher information issuing system and issuing method, telephone charge settlement system and telephone charge settlement method, and charge settlement system and charge settlement method

摘要

An object of the invention is to realize a valuable cipher information issuing system that is entirely free of a risk of theft during the course of distribution. To this end, a valuable cipher information issuing system 10 is constructed so as to be provided with cipher information storing means 12 for accumulating pieces of cipher information each being a string of a prescribed number of characters, requested amount of money input means 14 through which to select and input a desired amount of money, paid amount of money input means 16 through which to input an actually paid amount of money, valuable cipher information generating means 22 for generating valuable cipher information by correlating cipher information with the amount of money when the requested amount of money coincides with the paid amount of money, valuable cipher information storing means 24 for storing the valuable cipher information, and valuable cipher information output means 26 for outputting the valuable cipher information.
