Abstract

PURPOSE:To hold the secrecy of a password number by permitting an operator to generate fist process data from random numbers and a data process rule which he previously knows and to generate second process data from the data process rule corresponding to information and the random numbers and judging first process data to be the accurate personal identification number if both have agreed. CONSTITUTION:If the operator executes a specified operation to a terminal 2, an operation means 3 stores information based on the specified operation in a storage means 7, causes a random number generation means 6 to generate the random numbers and displays them in the terminal 2. Next, the operator generates first process data from the data process rule which corresponds to information and which he previously knows and from the random numbers, and he inputs them to the terminal 2. The data process rule which has been stored in the storage means 7 and which corresponds to information is inputted from a rule storage means 5 and second process data is generated. If first process data coincides with second process data, first process data is judged to be the accurate personal identification number. Thus, the secrecy of the personal identification number is held.
