Mini Project - BIO-METRICS
BIO-METRICS 1.ppt (Size: 217 KB / Downloads: 89) ABSTRACT Biometrics is seen by many as a solution to a lot of the user identification and security problems in today‘s networks. Password abuse and misuse, intentional and inadvertent is a gaping hole in network security. This results mainly from human error, carelessness and in some cases maliciousness. Biometrics removes human error from the security equation. Our paper will examine all the technological and feasibility aspects as well as the practical applications. INTRODUCTION The terms "Biometrics" and "Biometry" have been used since early in the 20th century to refer to the field of development of statistical and mathematical methods applicable to data analysis problems in the biological sciences. Recently, these terms have also been used to refer to the emerging field of information technology devoted to automated identification of individuals using biological traits, such as those based on retinal or iris scanning, voice patterns, dynamic signatures, fingerprints, face recognition, or hand measurements, especially for authentication purposes. CONCLUSION As the need increases for government bodies and large firms to deploy hi-tech security systems to solve crimes or protect employees, biometric technology will improve, as investor confidence increases.

Usable Biometrics
Usable Biometrics.doc (Size: 28 KB / Downloads: 48) Overview Biometrics literally means measurements of life from the Greek word “Bio” meaning Life and “Metric” meaning to measure. Technology that makes use of biometrics uses measurements of a person’s physiology and behavioral characteristics to do something. In security biometrics are often used for identification and verification. Identification: Identification is when the system tries to identify who the user is based on their biometrics. This is done by matching the current user’s characteristics to a large database containing all users. Identification has the potential problem of mistaking one person for another. An example would be a facial recognition system that mistakes one twin for the other. Verification: Verification is when the user has stated their identity and the system merely needs to confirm it. The system pulls up the record of the previously recorded characteristics and compares them against the biometrics of the current user. Types of Biometrics: There are many different types of biometric measurements possible. The two major types are physiological and behavioral. As examples the talk featured examples of each type of biometric using movies. Face: Face recognition works by looking at specific nodal points on the user’s face and comparing it against a database of previously recorded patterns. Nodal points are specific characteristics of the face such as the distance between eyes or the width of the nose. Face recognition is used in Airports and Las Vegas casinos to identify people who are on a watch list. NIST says it is 80-90% accurate in controlled condions. Eyes: There are two main types of biometrics involving eyes, retinal and iris. A retinal scan measures the pattern of blood vessels on the retina. This type of scan is fairly invasisve, the machine has to be very close to the eye and the subject has to hold very still. An iris scan examines the unique patterns of ridges on the colored portion of the eye. This is less invasive and the subject can be further away from the camera. Both eye scans are extremely accurate but won’t work on some groups such as the blind or people with cataracts. Class Discussion: Question: How identical are twins? . Identical twins do not have the same fingerprints or eyes since both are created as a result of the environment not as a result of DNA. . Twins do have very similar voices and faces. . Fraternal twins as well as siblings also have very similar voices and facial features. DNA: DNA works by taking a sample of the subject for example a drop of blood or a hair. The length and protein sequence of the DNA is then looked at to generate a profile which is compared against other profiles. Currently this is used by law enforcement and in paternity cases. This is also a very accurate method, it’s a 6 billion to 1 chance of having two people with the same DNA unless there is an identical twin. Class Discussion: . Privacy concerns. In the movie used as an example people were judged based on their DNA and not themselves. . Cleanliness concerns. How is a sample of the person collected? How much do you trust that needles are cleaned? What about HIV?

BIOMETRICS
BIOMETRICS.pptx (Size: 365.46 KB / Downloads: 25) INTRODUCTION The term biometris derived from greek words Bio means life and metric means to measure introduction It is associated with utilization of distinctive physiological characteristic for identifying individuals . Though most important application related with biometrics is that of security,it is used as computer interface too. A range of biometrics application are being used for authenticating person’s identity. FINGERPRINTS Fingerprint recognization is identify by using patterns of friction ridges and valleys on an individual fingertips which are unique to that individual IRIS Iris scanning seems futuristic but it uses simple DIGITAL CCD camera. It uses both visible and near infrared light to take a clear,high contrast picture of iris. In the scanner,camera focuses to make sure that the position is correct and eye is kept 3 to 10 inches from camera. When the camera takes a picture the computer locates. CONCLUSION Successful applications Decreasing cost and increasing convenience Increasing both privacy and identity security The field of biometrics is evolving Benefit from technology
