Zusammenfassung:PROBLEM TO BE SOLVED: To provide a PIN verification technique which makes verification possible without exposing a PIN to risk by transmitting the PIN through a network. SOLUTION: This on line personal identification number (PIN) verification technique uses polynomial concealment. This technique contains registration of a smart card (110). In the registration of the smart card, a matter is contained wherein the initialization of the smart card is performed in the status that a PIN selected by an entity is concealed in a polynomial on a finite field. An initialization polynomial is a function of the PIN, an entity identifier, and a random number. The random number and the PIN are discarded after the initialization of the smart card.
