What is Biometrics Definition: “Automated measurement of Physiological and/or behavioral characteristics to determine or authenticate identity” Biometrics is a security solution based on something you know, have, and are: Know Password, PIN Have Key, Smart Card Are Fingerprint, Face, Iris

Automated measurement” No human involvement. Comparison takes place in Real-Time.

Physiological and/or behavioral characteristics Behavioral: User speaks. Signs name Physiological: Fingerprint Hand Eyes Face

determine or authenticate identity Verification Systems More accurate. Less expensive. Faster. More limited in function. Requires more effort by user.

Why Biometrics?

Why Biometrics? Passwords are not reliable. Too many Can be stolen Forgotten Protect Sensitive Information Banking Medical

Biometrics-Applications

Biometrics-enabled Authentication Applications Cell phones, Laptops, Work Stations, PDA & Handheld device set. 2. Door, Car, Garage Access 3. ATM Access, Smart card Image Source : http://www.voice-security.com/Apps.html

Biometrics-enabled Identification Applications Criminel Tracking e.g. Fingerprints, DNA Matching Car Park Surveillance Frequent Customer Tracking

How biometric work

How biometric work Biometrics work by recording and comparing biometric characteristics. There are two type for biometric recognition Identification Verification

Identification Behavioral Physiological It mean identify and analyze the humane unique characteristic. It can divided in two types Behavioral Physiological

Identify Methods Fingerprint Face Recognition Signature Iris Scan Hand

Biometrics Verification Firstly collects data and information convert to digital format.

Then process the information and keep it Then process the information and keep it. Because that need to compare with new biometric data

After check and compare with new biometric data with data storage.

Finally recognize whether that information are real E.g.- In ATM machine verify your pass word or finger mark & If it is true then you can withdraw money.

Bio metrics devices

Bio metrics devices There are many types of bio metrics devices Commonly using 5 types of devices Iris scanner Finger print scanner Facial Biometrics Voice Recognition Other

iris scanner This scanner use for identify humens iris

Finger print Scanner Private and government sectors is using Finger print devices Earlier days used ink and paper method

Facial Biometrics Each and every persons have different and unique face. Use series of images for identify persons

Voice Recognition Some computer systems have voice recognition method Voice recognition is not the same as speech recognition, it is speaker recognition

Other

Advantages and Disadvantages

Biomatrix. ADVANTAGES DISADVANTAGES FINGERPRINTS ADVANTAGES A long-used method that is familiar and generally quick perform. Fingerprints are unique. A set of 10 prints yields highly accurate results. Cheap and easy to use. DISADVANTAGES Some people have poor prints because of injury, age, disease or occupation. Requires physical contact with a sensor and may have negative connotations because of use by law enforcement. . .

HAND GEOMETRY DISADVANTAGES. ADVANTAGES. Not suited for picking someone out of a large group. Sensors are large and relatively expensive ADVANTAGES. Fast and easy to use. Rugged and works well outdoors. . .

SPEECH VERIFICATION ADVANTAGES. Can use standard microphone or telephone handset and existing telephone lines. DISADVANTAGES Background noise, illness or stress can affect voice samples. Most accurate if similar instruments capture voice samples at enrollment and verification points. Not suited for picking someone out of a large group. .
