Abstract

본 발명은 컴퓨터에 많이 쓰이는 인터페이스 규격인 USB를 활용한 스마트 카드 및 인증 시스템에 관한 발명이다.The present invention relates to a smart card and an authentication system using USB, which is an interface standard commonly used in computers.

Description

ＵＳＢ를 내장한 스마트 카드 및 인증 시스템.{The smart card and authentication system with USB (Universal Serial Bus).}Smart card and authentication system with built-in USB. {The smart card and authentication system with USB (Universal Serial Bus).}

본 발명은 컴퓨터에 일반적으로 장착 되고 있는 USB를 활용한 인증시스템에 관한 발명으로 이와 비슷한 최근의 인증 시스템은 cd-rom(compact discread only memory)을 활용한 인증 시스템이 있으나 이런 시스템은 단순한 보조저장 메모리 장치로서 cd-rom 을 활용한 것으로 내부에 CPU(central Processing Unit)를 탑재하지 못하므로 스마트 카드의 기능을 갖지는 못하며, 휴대시에 파손의 위험이 있고 표면에 손상이 있을 경우 오독(誤讀)의 가능성이 있으며 자동 판매기등 cd-rom 이 장착되지 않은 기기에서의 사용이 불가능하다. 또한 복제 등 개인정보의 누설 가능성이 있다. 신용카드, 선불카드, 현금카드로 일반적으로 사용되는 스마트 카드의 경우는 cd-rom이 갖는 많은 단점을 극복하고 있으나 인터페이스 방식이 표준의 컴퓨터에 장착되어 있지 않으므로 인터넷에서 전자상거래용으로 사용하기에는 별도의 인터페이스 카드나 장치가 있어야 하며, 모든 컴퓨터에 인터페이스 카드를 보급하기에는많은 비용이 든다. 또한 다른 방안으로 컴퓨터의 병렬포트 (Parallel Port)나 직렬포트(Serial Port)를 활용 할 수 있으나, USB가 갖는 편의성을 따르지 못하며, 차후의 컴퓨터의 인터페이스는 USB로 통일 될 가능성이 크므로 USB를 활용한 인증 시스템이 갖는 장점은 더욱 크다.The present invention relates to an authentication system utilizing 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 memory. As a device utilizes cd-rom, it does not have a central processing unit (CPU) inside, so it does not have the function of a smart card, and there is a risk of damage when carrying it and misreading it when the surface is damaged. It is 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. However, since the interface method is not installed in the standard computer, it is not suitable for e-commerce on the Internet. You have to have 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 as an alternative, but it does not comply with 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.

본 발명의 목적은 컴퓨터에 최근 많이 보급되고 있는 USB 인터페이스를 활용한 인증 시스템으로 신용카드, 전자화폐, 인증 시스템, 사용자 확인, 보안 시스템등에 활용 할 수 있다. 또한, USB 인터페이스는 최근의 컴퓨터에 표준의 인터페이스로 장착되고 있으며, 많은 컴퓨터 주변기기가 USB를 지원하여 그 활용도는 더욱 커지고 있으며, 컴퓨터에서 USB를 통하여 전원을 공급하므로 스마트 카드 내부에 전원을 내장할 필요가 없어 더욱 소형화 할 수 있다.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.

도 1은 본 발명의 전체 블록 다이어 그램이다.1 is a complete block diagram of the present invention.

상기의 목적을 달성하기 위하여 USB 인터페이스부(10), CPU부(중앙 연산처리장치, 20), 저장장치부(메모리, 30)로 구성된 스마트 카드(40)와 USB 인터페이스부(50), 컴퓨터부(60)데이터 베이스부(70), 통신부(80)로 구성된 시스템(90)으로 구성하여 시스템과 USB 인터페이스로 연결된 스마트카드와 규정된 암호 알고리즘을 적용하여 스마트 카드에 저장되어 있는 각종 데이터를 시스템으로 전송하고 시스템에서 스마트 카드로 인증용 데이터와 저장용 데이터를 전송하여 상호인증을 한후 전자상거래, 신용카드, 전자화폐, 각종 인증 사용자 확인, 보안 확인기능을 승인한다.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, the smart card connected to the system and the USB interface and applying a 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 the smart card, e-commerce, credit card, electronic money, various user authentication and security verification functions are approved.

본 발명이 적용된 인종 시스템을 사용 할 경우 별도의 특별한 하드웨어의 추가 없이 저렴한 가격으로 컴퓨터에 최근 많이 보급되고 있는 USB 인터페이스를 통해 신용카드, 전자화폐, 인증 시스템, 사용자 확인, 보안 시스템 등에 활용 할 수 있다. 또한, USB 인터페이스는 최근의 컴퓨터에 표준의 인터페이스로 장착되고 있으며, 많은 컴퓨터 주변기기가 USB를 지원하여 그 활용도는 더욱 커지고 있고, 컴퓨터에서 USB를 통하여 전원을 공급하므로 스마트 카드 내부에 전원을 내장할 필요가 없어 더욱 소형화 할 수 있다. 휴대시에 파손의 위험이 적고 오독(誤讀)의 가능성이 없으며 자동 판매기 등의 기기에 USB 인터페이스를 저렴하게 부착 할 수 있다. 또한 복제 등 개인정보의 누설 가능성이 없고 신용카드, 선불카드, 현금카드로 일반적으로 사용되는 스마트 카드와 같은 기능을 가지면서도 스마트 카드가 갖는 대표적인 단점인 인터페이스 호환성이 보장되므로 인터넷에서 전자상거래용으로 사용하기에는 별도의 인터페이스 카드나 장치가 필요없이 즉시 활용 가능하다.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 the USB interface that is widely used in computers at a low price without adding any 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.
