PROBLEM TO BE SOLVED: To reliably discriminate the fact of the person himself, and reliably prevent an unfair practice by comparing data of base sequence in DNA recorded on a recording body such as a card carried by a discriminating object person with preregistered data of base sequence in DNA of the person himself. SOLUTION: First of all, a user inputs individual discriminating data such as a name and a code number from an input part 5 such as a keyboard, and compares and checks up this individual discriminating data with individual discriminating data preregistered on a database 3, and judges whether or not the user is the registered person himself. When both data coincide with each other, the user inserts a carried card 1, on which base sequence or the like in DNA is recorded, into a device, and reads data recorded on this card 1 by a reading means 2. It is compared and checked up with data on base sequence or the like in DNA of the person himself prestored in the database 3 by a data processor 4, and when they coincide with each other, various procedures such as repayment of a deposit or the like are permitted. |
