The classification rate has been estimated to about 87.0 % and 88.8% of unseen fingerprints for SVM and MLP classification respectively. Two different classification regimes are used to train the systems to do correct classification. The given fingerprint database is decomposed into four different subclasses. The fingerprint patterns generated are based on minutiae extraction from a thinned fingerprint image. Automatic Fingerprint Identification Systems (AFIS) are widely used today, and it is therefore necessary to find a classification system that is less time-consuming. For classification, a Support Vector Machine (SVM) and a Multi-Layered Perceptron (MLP) network are described and used. A loop pattern always comprises one delta, which is roughly a triangular formation in the pattern.In this work a hybrid technique for classification of fingerprint identification has been developed to decrease the matching time. They originate from one side of the finger, curve around or upward, before exiting out the other side.

There are basically three main forms of patterns that are made by the ridges of fingerprints.ġ) Loops: Loops make up almost 70 percent of fingerprint patterns. The following are some of the commonly used fingerprint patterns that have been identified and used in the process of fingerprinting. They are unique to each individual, and can be differentiated and identified based on certain distinctive patterns made by the ridges. Fingerprint PatternsĪ person’s weight, eye color, and hair color can change or be changed, but his fingerprints cannot be altered. This technology has even made the task of criminal identification much more efficient. The affordable, yet reliable digital fingerprinting and biometric devices of today are widely used in a number of small and large organizations for identifying their employees. With the advent of the digital age, the use of fingerprinting has substantially increased. These files became more and more important with the emergence of an increasing number of intellectual criminals, who crossed all legal and state lines. The Federal Bureau of Investigation established its first fingerprint identification division in the year 1924, with a collection of 810,188 fingerprint files, taken mostly from the Leavenworth Penitentiary. FingerprintingĪlthough most of us today are aware of the basic fact that each and every individual possesses a unique set of ridges on the hands and fingers, using them to identify people was not really accepted or even fully understood until the early 1900s. In the following sections, we shall first go through a few facts regarding fingerprinting, and then study some of the common fingerprint patterns that are utilized in this process. One of the most useful and tried and tested method from among these is fingerprint based identification.

Thankfully nowadays, we have much less painful and much more humane methods at our disposal. In the days gone by, many civilizations would use tattooing, branding, and even maiming as means of identifying people, especially the criminals. It is estimated that the chances of one person’s fingerprints matching up exactly with someone else’s is only about one in 64 billion.
