BIOMETRIC VOTING SYSTEM
[attachment=10792]
INTRODUCTION
 What is biometrics ?
 Applications of biometrics
 Use of biometrics in voting systems
WHAT IS BIOMETRICS?
DESIGN
 The design of the system consists of the following important parameters
1. Scanning- using DSP Processor
2. Searching- based on the principle of GOOGLE SEARCH
3. Networking- all the election booths are connected in a network
4. Data transfer– using telephone lines.

SUMMARY OF DESIGN
 Main aim -to provide concept of personal identity for each individual.
 Pre-poll procedure -finger prints of all the voters are collected.
 At the time of voting, option of voter is taken along with the finger print & sent to DSP chip.
 The option entered is transferred to chip through DEMUX and is stored in the memory.
DESCRIPTION OF THE VOTING MACHINE
BLOCK DIAGRAM FOR THE WHOLE PROCESS IN BRIEF:
 FINGER PRINT SCANNER
 The finger print scanner consists of the following parts:
1. FINGER PRINT SENSOR: Scans the thumb impression.
2. A/D CONVERTER: Converts the analog data from the sensor into the digital data.
3. FLASH ROM: Stores the data temporarily in the DSP processor.
4. DSP CHIP : Receives the data and processes it.
5. USB PORT: Establishes a communication page link between the DSP processor and the memory.
EXTRACTION OF THUMB IMPRESSION
 REJECTION OF VOTER REPETITION
 FORMATION OF THE NETWORK
ADVANTAGES
1.Highly reliable and secure.
2. Maintenance cost is very less
3. Illegal practices in elections can be checked for.
4. Instantaneous results with high accuracy.
CONCLUSION
 As the thumb impression of every individual is unique, it helps in maximizing the accuracy
 Illegal votes and repetition of votes is checked for in this system.
 Hence if this system is employed the elections would be fair and free from rigging.
