The Driving Test Authentication System Based On Arm Design

As the driving test is becoming stricter and stricter,electronic examination isgradually realized.In this case,identity authentication is particularlyimportant.Currently,the system of driving test is of singleauthentication,human-computer interaction unfriendly,expensive andinconvenient to upgrade.This paper proposes a set of embedded authenticationsystem,being capable of offline identity,fast authentication,and highsafety,convenient to install,upgrade and maintain.Firstly,this paper analyzed the state of development of identity authenticationtechnology,pointed out that fingerprint information stored in the IC card andwith field-collected fingerprint comparison,can better able to achieve the unityof people and card,and higher security.Secondly, by the integrated hardware andsoftware considerations, thesis takes S3C2440as the core of the systemcontroller, and builds the hardware platform of the system according to therequirement; to compare the many IC cards in the market,subjects choose theFudan’s FM1208card as a fingerprint template vector,and study its internalstructure and principles,design the corresponding card module;through thefingerprint module implements fingerprint acquisition,storage,comparison ofpersonnel and control operation of the IC card internal data;and according to thedemand of design corresponding onboard signal acquisition module and a powersupply part.Third, according to the characteristics of the hardware platform ofthe system,topics complete the u-boot and Linux kernel transplantation,andmake the root file system;analysis and design the system serial prort driver andvehicle signal acquisition driver;according to the design requirements,completethe card reader module design,realization of the IC card read and writefunction.Fourth, by comparing different feature of GUI,system chooses Qt/E asthe interface design;designs the IC files and stores user information,reads thefingerprint data in IC card,and compares with the field fingerprint,finallyrealizes the function of identity authentication. The organic combination of fingerprint recongnition technology and IC cardtechnology,which greatly improve the security of the identity,interfacedesign,but also improve the friendliness of human-computer interaction.Thisprovides a new direction for the future of the driving test authentication,and hasbroad market prospects.
