BIOMETRIC VOTING SYSTEM PRESENTED BY :- ANJALI YADAV 08IT518

What is biometrics?? Biometrics is the science that tries to fetch human biological features with an automated machine either to identify or authenticate. The traits may be fingerprints, hand geometry, facial geometry, retina patterns, voice recognition, and handwriting recognition. Biometric products remove the need for passwords and Personal Identification Numbers or PINs. It makes it comfortable and fast to record features.

Need for biometric voting system It has always been an arduous task for the election commission to conduct free and fair polls in our country. Now- a -days it has become common for some forces to indulge in rigging which may eventually lead to a result contrary to the actual verdict given by the people. So there is need for a new voting system employing biometrics in order to avoid rigging and to enhance the accuracy and speed of the process.

Biometric Features Fingerprint :-Fingerprint scanners are probably the most commonly used biometric system.Similar systems include hand geometry or palmprints Iris :-Another static property of individuals are eyes. One can either use pictures of the person’s iris or use a retina scanner that scans blood vessels to create an individual data set. Face :-Human face recognition by analyzing the size and position of different facial features is being pushed for use at several airports to increase security.

Biometric Features Voice :-A more behavioral individual aspect of humans are their voices. Everybody has a special mode and tone while speaking. Voice recognition tries to analyze these features and use them to identify a person. DNA analysis :-This is a rather more theoretical idea for biometric identification. Imagine a DNA reader that can create a full DNA analysis within seconds from just a few cells of a person’s body. Such a device would surely be a match to, e.g. a finger print reader, when comparing the quality of the results. Multi-Biometric Systems :-As a final approach to biometric data gathering, one can combine two or more actual biometric analyses and combine their results.

Block Diagram of the process

Design 1. Scanning- using DSP Processor 2. Searching- the thumb impression of a voter is entered as input and compared with the available records in the database. 3. Networking- all the election booths are connected in a network 4. Data transfer– using telephone lines

Finger print scanner 1. FINGER PRINT SENSOR: Scan the thumb impression. The data obtained from this is analog in nature. 2. A/D CONVERTER: Converts the analog data from the SENSOR into the digital data 3. FLASH ROM: This is for the storage of the data temporarily in the DSP processor. This will work until the data is transferred to the main memory of the HOST. 4. DSP CHIP: This is used to receive the data and process it. This is connected to the USB port for further transfer of the data. 5. USB PORT: The sole purpose of the USB port is to establish a communication link between the DSP processor and the MEMORY (DATABASE).

Extraction of thumb impression The features of the finger print are stored in the form of pixels. This is further sent for pattern matching where the finger print is then compared with the records in the database.

Scanning…Processing…Transfer The biometric sensor scans the image. This so scanned data is in the analog form. This is converted into digital form by using an A/D converter. The data received from the parallel in ports is further processed in the chip. The data which is processed in the DSP chip (finger print) is transferred in parallel to the HARD DISK for searching process. The HARD DISK is also interfaced in parallel with the chip. This helps the chip to transfer the image to the HARD DISK for further process. The image transferred to the HARD DISK is compared with that of the DATA BASE.

Example… 1. Party one, 2. Party two, 3. Party three, 4. Party four. Selected option2 Binary data transferred to port0010 After counting ,count of each party transferred to the transmitter. The transmitter data is transferred through the telephone lines to the HOST. The counts of similar parties are added at the host and the data is transferred to the STATE HEAD QUARTERS (main HOST) to display the result of the particular constituency.

Verification of Voters

Processing and Counting

Rejection of Voter Repetition

Formation of a Network

Advantages… The system is highly reliable and secure. In the long run the maintenance cost is very less when compared to the present systems. Illegal practices like rigging in elections can be checked for. Also the police station nearby to the election poll booth is informed about the identity of the imposter. It is possible to get instantaneous results and with high accuracy.

Conclusion… Thus the advent of this biometric thumb impression voting system would enable hosting of fair elections in India. This will preclude the illegal practices like rigging. The citizens can be sure that they alone can choose their leaders, thus exercising their right in the democracy.
