WHAT SECURITY ? WHY SECURITY ? • SECURITY SYSTEM • ALEXENDAR FISH & LINAS YEL - 1844
INTRODUCTION BIO = PERTAINING TO BIOLOGY & METRICS = SCIENCE OR ART OF MEASUREMENT • FUNDAMENTAL OPERATIONS 1.CAPTURE 2.EXTRACTION 3.COMPARISON 4.MATCH/NONMATCH
A FEW DEFINATION • BIOMETRICS AUTHENTICATION • BIOMETRICS,BIOMETRIC OR BIOMETRY • AUTHENTICATION Vs IDENTIFICATION
HISTORY OF BIOMETRICS • FRANCIS GALTON – 1892. • In 1968, Biometrics technique was implem- ented in New York bank. • But after1990, IT comes in picture ,through Its advancement and simplicity Biometrics Technique become very popular.
PHASE OF BIOMETRICS 1.INPUT 2.PROCESS 3.OUTPUT
BIOMETRICS IDENTIFICATION • VOICE PRINT • FINGER PRINT • IRIS PATTERN • FACE PRINT • HAND GEOMETRY • RETINAL SCAN • KEYSTROKE DYNAMICS • FACIAL RECOGNITION • SIGNATURE RECOGNITION
VOICE PRINT • Voice print is recorded by microphones. • Voice print is determined by many different factors: size of vocalcactivites (throat, oral, nasal) as well as the characteristic of the vocal chords themselves. • Your voice is further modified by the way you speak the way your mouth, lips, teeth, jaw and tongue move. Therefore, the chance of two people have BACK
FINGER PRINT • Finger print is also called finger scanning. • To scan the finger print, a special kind of scanner that can work with optical rays is used. • it fetches the diagram of finger print & delivers it to the computer where a special programmer measures the distance between the special features & that print. • Here, those special features are core, split, island, end &delta. Most fingerprint data takes up around 250kb BACK
IRIS PATTERN • Iris is located behind the cornea of the eye and front of the lens. Its only physiological purpose is to control the amount of light that enters the eye through the pupil, but iss construction from elastic connective tissue gives it a complex, fibrillous pattern. • Finger print technique there are only 90 special features, but in iris pattern there are 266 special features. BACK
FACE PRINT • It use various features of the face to recognize or verify a user. • Use various kind of camera and computer . • The computer converted this feature into digital form. . BACK
HAND GEOMETRY • Most widely used biometrics sys. • It use the geometric shape of the hand for authenticating the user’s identity. • Generally two method is used: 1. mechanical. 2. Image edge detection. • Hand scanner is used in this method which is shown in fig. BACK
RETINA SCAN • Retina scan method is based on the blood vessel pattern in the retina of eye. • The device used in this method is shown in the fig. on this the user position there head against a support and a low power infrared light is directed against the back of the retina. BACK
KEYSTROKE DYNAMICS • This method analyzes the way in which a user types at a computer keyboard. • The durations of keystrokes and the latencies between them are recorded BACK
FACE RECOGNITON • Facial recognition technique has recently developed into two areas of study; 1. Facial metrics. 2. Eigenfaces. BACK
SIGNATURE RECOGNITION • It is based on the dynamics of making the signature. i.e. accretion rates, direction, pressure, stroke length etc. • The problem is measurement used in the recognition process and repeatability of the signature. NEXT BACK
COMPARISON OF BIOMETRICS TECHNIQUES • Table show the crossover accuracy of different biometrics. • crossover accuracy is the ratio of the crossover Frequency as compared to the whole population of tested data.
HOW WELL DO BIOMETRICS WORK? • FALSE ACCEPT RATE • FALSE REJECT RATE • EQUAL ERROR RATE • VALIDITY OF DATA
IS DNA A BIOMETRICS? • DNA differs from standard biometrics in several ways. • DNA is type of biometric in as much as it is the use of physiological characteristic two verify or determine identity.
ABOUT BIOMETRICS • Where Biometrics is used? • The new opportunities & Future Technologies. • Benefits.
