ELECTRNIC BASED ELECTRONIC VOTING MACHINECONTENT:INTRODUCTIONWHAT IS EVMBLOCK DIAGRAMADVANTAGESDISADVANTAGESCONCLUSION

INTRODUCTIONThe main aim of this project is to avoid rigging completely. Electronic voting systems have come into picture to prevent rigging up to the maximum extent. But even there may be some malfunctions during elections. Thus, fingerprint based electronic voting system has been designed. According to ancient Greek scripts BIOMETRICS means study of life. Biometrics studies commonly include fingerprint, face, iris, voice, signature, and hand geometry recognition and verification. Many other modalities are in various stages of development and assessment. Among these available biometric traits, Finger Print proves to be one of the best traits providing good mismatch ratio and also reliable. The present scenario to operate a bank locker is with locks which are having keys. By this we cant say that we are going to provide good security to our lockers. To provide perfect security and to make our work easier, we are taking the help of two different technologies viz. EMBEDDED SYSTEMS and BIOMETRICS.

What is an Electronic Voting Machine?It is a simple electronic device used to record votes in place of ballot papers and boxes which were used earlier in conventional voting system.BLOCK DIAGRAM

POWER SUPPLYSTEP DOWN TRANSFORMER230V-9VIC7805REGULATORBRIDGE RECTIFIER1000uF Capacitor1000uF CapacitorOPERATION Initially 230 V Ac supply is reduced to (0-9V) with the help of a step down transformer having a capacity of 500mA.This low voltage is rectified with the help of bridge rectifier. The ripples are minimized with the help of capacitor filter to get a smooth DC supply. The rating of the chosen capacitor filter is 1000UFThe regulated DC voltage is obtained by using a regulator IC 7805Another capacitor filter of rating 10UF is connected at the output of regulator IC to eliminate the voltage oscillations at the output due to the large voltage oscillations at the input of the regulatorADVANTAGES It makes the process of counting of votes much faster than the conventional system.It reduces cost of printing almost nil as only one sheet of ballot paper required for each PollingStation.It reduces to a great extent the quantity of paper used thus saving a large number of trees makingthe process eco-friendly.DISADVANTAGESviruses Hacking physical tampering. CONCLUSIONElectronic Voting Machine (EVM) retains all the characteristics of voting by ballot papers, while making polling a lot more expedient. Being fast and absolutely reliable, the EVM saves considerable time, money and manpowerTHANK YOU
