FINGER PRINT BASED E-VOTING MACHINE
FINGER PRINT.doc (Size: 1.37 MB / Downloads: 88) ABSTRACT According 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 EVM’s having selection keys to select the person to who we need to vote. By this we can’t say that the authenticated person votes in a right way. To provide perfect security and to make rigging free, we are taking the help of two different technologies viz. EMBEDDED SYSTEMS and BIOMETRICS. Firstly discussing about Biometrics we are concentrating on Fingerprint scanning. When this module is interfaced to the microcontroller, we will be using it in user mode. In this mode we will be verifying the scanned images with the stored images. When coming to our application the fingerprint images of the persons who are authorized to vote in elections will be stored in the module with a unique id. To prove that the persons are authorized for voting they need to scan their fingers using fingerprint module. This scanner is interfaced to 8051/ARM microcontroller. This scanner is interfaced to 8051 microcontroller through max232 enabling serial communication. By using this controller we will be controlling the scanning process. After the scanning has been completed the result is stored in database of the controller. When we press a key controller it displays the no. of votes acquired by each candidate on the LCD. INTRODUCTION TO EMBEDDED SYSTEMS An embedded system is an application that contains at least one programmable computer (typically in the form of a microcontroller, a microprocessor or digital signal processor chip) and which is used by individuals who are, in the main, unaware that the system is computer-based. Typical examples of embedded applications that are constructed using the techniques discussed in this book include: • Mobile phone systems (including both customer handsets and base stations). • Automotive applications (including braking systems, traction control, airbag release systems, engine-management units, steer-by-wire systems and cruise control applications). • Domestic appliances (including dishwashers, televisions, washing machines, microwave ovens, video recorders, security systems, garage door controllers). • Aerospace applications (including flight control systems, engine controllers, autopilots and passenger in-flight entertainment systems). • Medical equipment (including anesthesia monitoring systems, ECG monitors, drug delivery systems and MRI scanners). • Defence systems (including radar systems, fighter aircraft flight control systems, radio systems and missile guidance systems). NEED FOR FINGER PRINT E-VOTING MACHINE The present scenario to vote in the elections using Electronic Voting Machines (EVM’s) which are having keys to vote a candidate. By this we can’t say that the authorized citizen is voting. To provide perfect security and to make our work easier, we are taking the help of two different technologies viz. EMBEDDED SYSTEMS and BIOMETRICS. Firstly discussing about Biometrics we are concentrating on Fingerprint scanning. When this module is interfaced to the microcontroller, we will be using it in user mode. In this mode we will be verifying the scanned images with the stored images. When coming to our application the images of the persons who are authorized to enter into the locker room will be stored in the module with a unique id. To prove that the persons are authorized to enter that area they need to scan their images. PROJECT OVERVIEW BRIEF METHODOLOGY: Manual voting of the people is a difficult one. In order to monitor these facts automatically, this microcontroller based system is proposed to develop. This project uses fingerprint scanner, 3x3 keypad, LCD display and buzzer. Thumb impression is stored in the database. When the voter keeps his thumb in the scanner the system searches for the matches which is already fed. If it matches, the LCD will display please poll your vote. When voter presses the button the voting is done. After the vote is finished in the LCD shows the message your vote is registered. If suppose an invalid voter or already voted person comes for voting booth and when his thumb impression is scanned, the buzzer makes a continuous beep sound and also the LCD will display that the unauthorized person is making to vote. Principles of fingerprint biometrics A fingerprint is made of a a number of ridges and valleys on the surface of the finger. Ridges are the upper skin layer segments of the finger and valleys are the lower segments. The ridges form so-called minutia points: ridge endings (where a ridge end) and ridge bifurcations (where a ridge splits in two). Many types of minutiae exist, including dots (very small ridges), islands (ridges slightly longer than dots, occupying a middle space between two temporarily divergent ridges), ponds or lakes (empty spaces between two temporarily divergent ridges), spurs (a notch protruding from a ridge), bridges (small ridges joining two longer adjacent ridges), and crossovers (two ridges which cross each other). The uniqueness of a fingerprint can be determined by the pattern of ridges and furrows as well as the minutiae points. There are five basic fingerprint patterns: arch, tented arch, left loop, right loop and whorl. Loops make up 60% of all fingerprints, whorls account for 30%, and arches for 10%. MICRO CONTROLLER Brief History In 1981, Intel Corporation introduced an 8-bit microcontroller called the 8051. This microcontroller had 128 bytes of RAM, 4K bytes of on-chip ROM, two timers, one serial port, and four ports (each 8-bits wide) all on a single chip. At the time it was also referred to as a "system on a chip." The 8051 is an 8-bit processor, meaning that the CPU can work on only 8 bits of data at a time. Data larger than 8 bits has to be broken into 8-bit pieces to be processed by the CPU. The 8051 has a total of four I/O ports, each 8 bits wide. See Figure 1-2. Although the 8051 can have a maximum of 64K bytes of on-chip ROM, many manufacturers have put only 4K bytes on the chip. This will be discussed in more detail later. The 8051 became widely popular after Intel allowed other manufacturers to make and market any flavors of the 8051 they please with the condition that they remain code-compatible with the 8051. This has led to many, versions of the 8051 with different speeds and amounts of on-chip ROM marketed by more than half a dozen manufacturers. Next we review some of them. It is important to note that although there are different flavors of the 8051 in terms of speed and amount of on-chip ROM, they are all compatible with the original 8051 as far as the instructions are concerned. This means that if you write your program for one, it will run on any of them regardless of the manufacturer. |
