Literature Review

There are several ways to start a vehicle. One of them is by key. Key is a basic system that has been created for all types of vehicles. For a fast moving technology, a conventional key is replaced with a more sophisticated system for security reason, although key systems are still available until now. Push button and smart key is part of the option for user to start their vehicle engine [9].This system look more advanced compare to conventional keys. But the problem of having this system is that it is not fully secure. One of the preferable methods is by using thumbprint system. This system is more secure compared to keys. This system will use left and right thumbprint. Every person has different thumbprint. Thumbs is divided into several types and different circles such as loop, arch and whorls.

Fingerprints are usually partitioned into five main classes (arch, tented arch, left loop, right loop and whorl) according to the number and position of their macro-singularities [10].The ridgeline flow can be effectively described by a structure called directional map, which is a discrete matrix whose elements denote the orientation of the tangent to the ridge lines. Analogously, the ridge line density can be summarized by using a density map. Within these three categories there are about 30 different minutia points [11]. This is what makes fingerprint so unique is because no one has the same number of minutia points in the same place. Also between right and left thumb, there are still differences.

Other very important features can be discovered in fingerprint patterns. These micro singularities, called minutiae or Galton characteristics, are essentially determined by the termination or the bifurcation of the ridge lines.The system will use fingerprint reader and the key as an input, then the microcontroller will process data received from the input and then move it to the starter motor and LED indicator.
