Study Of Union Authentication System Based On The Vein Verification

Biological authentication is a kind of new-type authentication method , it carries on the authentication ground technology of the identity according to human body's inherent physiological characteristic or the behavior characteristic. The combination with the technology of the computer, make biological authentication technology widely used in a lot of fields. This text has put forward the implementation method of the union authentication system based on the hand vein and radio-frequency.As a part of union authentication system ,The paper to the radio frequency confirmation, the video signal, the USB bus technology and the USB2.0 connection chip the characteristic has carried on the introduction; then ,the design base on EZ-USB FX2 CY7C68013, issued by Cypress Semiconductor Corporation ,which capture radio frequency card data and the real-time video image data, has been given.In hardware segment, each circuit's function is introduced in detail.On Software design,Study the design of EZ-USB FX2 firmware,General Purpose Driver and PC applications, and write the simple test program.Lastly the reason which effects the quality has been analysed.
