Fingerprint Recognition Essay

1443 Words6 Pages

Fingerprint recognition refers to the automated process of verifying a match between human fingerprints. Fingerprints are one of the types of biometrics used for identifying individuals and verify their identity. The analysis and study of fingerprints for matching generally requires the comparison of several features of the fingerprint pattern. These include patterns, which are characteristics of ridges and minutia points, which are unique features found within the fingerprint patterns. It is also essential to know the structure and properties of human skin to successfully employ some of the imaging technologies. There are many human biometric features that can be used to confirm the identity ,such as voice, hand geometry, face, finger print and retinal pattern of eye. Among all these features, finger print matching is the most popular and reliable biometric technique for automatic personal identification. …show more content…

Sixty to sixty five percent populations have loops, thirty to thirty five percent has whorls, and about five percent are arches. These three classes form the basis for all the ten-finger classification systems presently in use.
i. Arch:
In arches the ridges of the finger run from one side to the other with no re-curving. There are two sub groups
Plain arch- This pattern has a consistency of flow in it. It starts from one side of the finger, and then the ridge cascades upward slightly. The plain arch then continues its journey along the finger to the other side.
Tented arch- In tented arch ridges are in the center which are not continuous as in the case of plain arch. The ridges, which adjoin each other in center, converts and thrust upward, giving the impression of the pitched tent.

The shoe prints were later identified to be a match to one another and ultimately belonged to Ramirez. All of these details didn't emerge or emanate together until after Ramirez was caught. After Ramirez's arrest, authorities say his fingerprints were matched with prints found at serval of the crime scenes. Finger print comparison and identification is done by a trained forensic scientist, additionally computerized systems are used to search fingerprint databases for potential print matches. Fingerprint analysis is conducted using the ACE-V method to make a determination on the print and is done in

The Pros And Cons Of Fingerprinting

1172 Words | 5 Pages

Fingerprinting is method based on the uniqueness of the skin pattern - that is, each person has a completely individual pattern of papillary lines. These patterns do not change throughout life and have the property of recovering from damage to the skin in its previous form. On the one hand, this method almost completely eliminates the mistake, and on the other hand it is very cheap and easy to use (in contrast the method of identification of a person by DNA). Fingerprinting allows: 1) to identify the person who left the prints, according to the general and particular features of the papillary pattern displayed on them; 2) to exclude individual from among those who have touched the object; 3) to narrow the group of individuals suspected of the particular crime (for instance, provided that the imprint shows traces of a scar, a burn, a wart or some other distinctive feature).

Facial recognition technology is Face recognition is the automated process of comparing two images of faces to determine whether they represent the same individual. It relies on algorithms to locate a person’s face within the photo, after which the face is normalized (scaled, rotated, aligned, so that every face is analyzed from the same position). Next, the algorithm extracts features from the face that can be numerically quantified and then it examines pairs of faces and issues a numerical score based on the similarity of their features. This technology is employed by the FBI, as well as state and local law enforcement. One in two adults has their photos searched this way, primarily including law abiding citizens.

In this form columns are often placed very close together and generally did not have bases to the columns. The shafts of the columns were constructed with concave curves called flutes and the capitals of the columns would be plain and they would have a rounded section near the bottom of the element, these were called the echinus, the capital would also have a square at the top, this element was known as the abacus. Another distinctive part of the Doric form is the frieze of the entablature, the frieze is decorated with vertical channels, which are called triglyphs. The spaces located between these triglyphs are called the metopes, these metopes could be left plain but were often sculpted for extra decoration with ornamentation or figures. The frieze and architrave of the entablature in the Doric form were separated by a band called the

Essay On Face Recognition Technology

704 Words | 3 Pages

2.1 Face Recognition Technology Human individuality is often identified using faces, advancements in computing capability over the past few decades now enable similar recognitions. Recognition process has now matured into a science of sophisticated mathematical representations and matching processes from geometric model. Face recognition can be used for both verification and identification (open-set and closed-set).Facial recognition is achieved by means of comparing the rigid features of face, which do not change over a period of time. It can also be achieved by comparing other parameters such as skin tone against the information that are stored in the facial database.

Because it offers a non-intrusive way for human identification, the face is used as an important biometric in security applications .Recently, face recognition has received wide interest in number of countries are integrating facial information into electronic passport and to other biometrics (fingerprints and iris) [9]. In addition to security and law enforcement, face recognition is also applied in entertainment and consumer electronics as a means for a natural user interface. By recognizing the existence of the user and his identity, consumer devices can offer customized services, thereby creating an enhanced user experience.
