Abstract

The present invention relates to a smart card and an authentication system using USB, which is an interface standard commonly used in computers.

Description

Smart card and authentication system with USB built in {Smart card and authentication system with USB}

The present invention relates to an authentication system using USB that is generally installed in a computer. Similarly, a recent authentication system has an authentication system using a cd-rom (compact discread only memory), but such a system has a simple auxiliary storage.

As a memory device, it uses cd-rom, and it does not have a central processing unit (CPU) inside, so it does not have the function of a smart card. ), And it is not possible to use it on a machine without a cd-rom, such as a vending machine. In addition, there is a possibility of leakage of personal information such as duplication.

Smart cards commonly used as credit cards, prepaid cards, and cash cards overcome many of the disadvantages of cd-rom.

You need an interface card or device, and it's expensive to deploy an interface card in every computer. In addition, you can use the parallel port or serial port of the computer in other ways, but it does not follow the convenience of USB, and the interface of the computer in the future is likely to be unified to USB. The advantages of one authentication system are even greater.

An object of the present invention is an authentication system using a USB interface that is widely used in computers recently, it can be used for credit cards, electronic money, authentication systems, user verification, security systems and the like. In addition, the USB interface is equipped as a standard interface in recent computers, and many computer peripherals support USB, and its utilization is further increased. Since the computer supplies power through USB, it is necessary to embed power inside the smart card. It can be further miniaturized.

In order to achieve the above object, the smart card 40 consisting of the USB interface unit 10, the CPU unit (central processing unit 20), the storage unit (memory) 30, the USB interface unit 50, and the computer unit (60) It consists of a system (90) consisting of a database unit 70, the communication unit 80, by applying a smart card connected to the system and the USB interface and the prescribed encryption algorithm to the various data stored in the smart card to the system After mutual authentication by transmitting authentication data and storage data from the system to smart card, e-commerce, credit card, electronic money, various authentication user confirmation, and security verification function are approved.

When using the race system to which the present invention is applied, it can be utilized for credit card, electronic money, authentication system, user verification, security system, etc. through USB interface, which is widely used in computers at a low price without the addition of special hardware. In addition, the USB interface is equipped as a standard interface in recent computers, and many computer peripherals support USB, and its utilization is further increased. Since the computer supplies power through USB, it is necessary to embed power inside the smart card. It can be further miniaturized. There is little risk of damage when carrying, there is no possibility of misreading, and USB interface can be attached inexpensively to vending machines and other devices. In addition, there is no possibility of leakage of personal information such as duplication, and it has the same function as smart card commonly used as credit card, prepaid card, and cash card, but also guarantees interface compatibility, which is a representative disadvantage of smart card, and is used for e-commerce on the Internet. There is no need for a separate interface card or device.

USB interface unit 10, CPU unit (central processing unit, 20), storage unit (memory, 30)

The system consists of the smart card 40 and the USB interface unit 50, the computer unit 60, the database unit 70, the communication unit 80 is configured

(90), by applying the smart card connected to the system and the USB interface and the prescribed encryption algorithm to transfer various data stored in the smart card to the system, and to transmit the authentication data and storage data from the system to the smart card After mutual authentication, approve e-commerce, credit card, electronic money, various authentication users, and security verification functions.

1 is a complete block diagram of the present invention.
