Three WH to Biometrics : 

Three WH to Biometrics What is Biometrics? Person’s vital statistic Physics of human body Behavioral study of human Why Biometrics? Emerging technology To Identify Or Verify Promises effective solution They cannot be stolen and used to access personal information. Biometrics are effective to secure privacy and deter identity theft. Continue…

PowerPoint Presentation: 

Where the biometrics are used? Used all over for security purpose Biometric systems can be used as physical access granting systems Can be used to establish entitlement to services and rights that are restricted to a certain group of individuals. Voting rights etc. Can be used for the recording and association of facts. Like employee attendance, forensics etc. Three WH to Biometrics

Types of Biometrics: 

Types of Biometrics Biometric is derived from the Greek words 'bios' and ‘metric’ which means life and measurement respectively So it is a measurement physically as well as behaviorally

Behavioral Biometrics : 

Behavioral Biometrics Measures the characteristics which are acquired naturally over a time. It is generally used for verification. Examples:- Speaker recognition Signature Keystroke

Physical Biometrics: 

Physical Biometrics Physical biometrics measures the inherent physical characteristics on an individual. Can be used for either identification or verification. Examples:- Finger prints Facial Recognition Hand geometry Irish scan Retinal scan Vein pattern DNA.

Fingerprint Recognition: 

Fingerprint Recognition E xtremely useful technology. Recognized as a primary and accurate identification method. Involves taking an image of a person's fingertips It records fingertips' characteristics like whorls, arches, and loops along with the patterns of ridges, furrows, and minutiae. To capture the fingerprints, current techniques employ optical sensors that use a CCD or CMOS image sensor. Continue…

Fingerprint Recognition: 

Fingerprint Recognition Issues :- Fingerprints do not provide a clear intention to authorize It Can be obtained from latent prints left on objects or forced onto readers. Many readers do not check for the ‘Live’ finger

Face Recognition: 

Face Recognition It records face images through a digital video camera and analyses. It measures characteristics like the distance between eyes, nose, mouth, and jaw edges. Measurements are broken into facial planes and retained in a database, further used for comparison. There are many techniques for face recognition like face geometry, Facial thermo grams

Face Recognition: 

Face Recognition Issues :- As you grow old it challenges the face The changes in our faces like beards, change in hair can lead to difficulties to authenticate. Face recognition can be based on video or image so require high-tech resources for that

Voice Recognition: 

Voice Recognition Combines physiological and behavioral factors to produce speech patterns Inherent properties of the speaker like fundamental frequency, nasal tone, cadence, inflection, etc. are used for speech authentication. Three methods are there Fixed text Text Dependent Text Independent

Voice Recognition: 

Issue:- The performance of all voice biometric solutions is influenced by Environmental background noise, making their deployment restricted. Voice Recognition

Irish Recognition : 

Irish Recognition Analyzes features like rings, furrows, and freckles existing in the colored tissue surrounding the pupil. The scans use a regular video camera and works through glasses and contact lenses. The image of the iris can be directly taken by making the user position his eye within the field of a single narrow-angle camera. Iris recognition was piloted in Saudi Arabia as a method of keeping track of the millions making Hajj.

Irish Recognition : 

Issue:- Environmental lighting and user positioning are important factors in performance. Dark iris color intensity can affect the ability to correctly distinguish pattern markings, along with the use of colored or tinted contact lenses. Long eyelashes can make the iris less visible. Irish Recognition

Hand Geometry: 

Hand Geometry Hand geometry systems are commonly available in two main forms. Full hand geometry systems take an image of the entire hand for comparison while Two Finger readers only image two fingers of the hand Hand recognition technology is currently one of the most deployed biometrics disciplines world wide A camera capture an image of the hand, with the help of a mirror to get also the edge. The silhouette of the hand is extracted, and some geometrical characteristics stored.

PowerPoint Presentation: 

Issue:- Some times people can have same geometry of a hand and in some unusual cases these techniques get fail. Failing of this system is very rare. Hand Geometry

Retina Recognition: 

Retina Recognition Technology uses infrared scanning and compares images of the blood vessels in the back of the eye Retina scan is used in high-end security applications like military installations and power plants Costing high compare to other techniques

Retina Recognition: 

Issue:- Enrollment and scanning are intrusive and It uses infrared so at long time harmful to human eye. Retina Recognition

Signature recognition: 

Signature recognition It is an instance of writer recognition, which has been accepted as irrefutable evidence in courts of laws The way a person signs his name is known to be a characteristic of that individual Approach to signature verification is based on features like number of interior contours and number of vertical slope components. Signatures are behavioral biometric that can change with time

Signature recognition: 

Issue:- professional forgers can reproduce signatures to fool an unskilled eye and hence is not the preferred choice. Signature recognition

DNA Recognition : 

DNA Recognition It employs Deoxyribo Nucleic Acid, which is the one-dimensional ultimate unique code for ones individuality it is currently used in the context of forensic applications. The basis of DNA identification is the comparison of alleles of DNA sequences found at loci in nuclear genetic material.

DNA Recognition : 

Issue:- Twins can have same DNA It is too much sensitive DNA Recognition

Comparison Between Types: 

Comparison Between Types

Making The Biometric System Fool: 

Making The Biometric System Fool Fooling the fingerprint reader-: Breathing on readers can re-activate the last latent Simply pressing a copy of a latent can fool some readers Water in a bag being pressed can re-activate the last latent Irish-: while testing fingerprint readers checked out one Iris scanner, and was able to fool it using a simple photo with a hole cut for the pupil

Making The Biometric System Fool: 

Making The Biometric System Fool Facial: - Facial recognition was simply fooled by the simple replay of a video clip. Signature-: A handwriting expert with closer analysis is able to deduce an individual’s manner of signing and therefore eliminate attempted forgery

Future Of Biometrics: 

Future Of Biometrics Biometric technology will further develop 3-D infrared facial recognition access control Also real-time facial recognition passive surveillance, and visitor management authentication systems. Also Indian government is going to use the biometrics in Unique Identification Project
