Embodiment Construction

[0048]In the electronic value information transmission method according to the present invention, when an IC card capable of recording electronic value information (hereinafter, referred to as electronic value) such as electronic money, electronic bill, etc., or an IC card capable of recording electronic value When electronic value is transferred between electronic systems of the company, not only the copying and deletion of the sender's electronic value is performed. In this method, the sender and the recipient are identified by mutual authentication, and the electronic value is deleted after confirmation that the electronic value was transmitted to the recipient without failure. Thus, problems of illegal copying of electronic value information, loss of electronic value information due to communication failure, and the like are solved.

[0049] Hereinafter, a detailed description will be given of a method of transmitting an electronic value shown as an embodiment of the prese...

Abstract

A method and system of transmitting electronic value information between terminals. The method includes the steps of: authenticating each other between a transmission source terminal and a destination terminal; sharing authentication for common information obtained by the authentication; encrypting data including the electronic value information to be transmitted; transferring the encrypted electronic value information to the destination terminal when the terminals are recognized with each other; temporarily invalidating the electronic value information left in the source terminal; transmitting reception confirmation to the source terminal when the destination terminal completes reception of the electronic value information; deleting the invalidated electronic value information left in the source terminal when the reception confirmation is received by the source terminal; transmitting validation information to the destination terminal after the deletion of the electronic value information in order to validate the electronic value information; receiving and validating the electronic value information by the destination terminal.

Description

technical field [0001] The present invention relates to a method and system for transmitting electronic value information, wherein the value information of so-called electronic value is sent and received using the following non-contact (or contact) IC card or using an electronic system having the IC card Yes, the IC card has a memory function for holding data, and can read data from and write data to the memory in a non-contact manner. Background technique [0002] It is common to use a personal identification number or a password to perform user identification, authentication processing, etc. when using a specific service. For example, when a user uses a cash or credit card at a financial institution such as a bank, the user is prompted to enter a personal identification number or password at a bank terminal such as an automated teller machine. If it is confirmed that the user entered the correct PIN or the correct password, the user is allowed to perform financial transac...
