A SEMINAR ON

BIOMETRICS SECURITY SYSTEM Presented By:-GAZAL GUPTAVIII-SEM IT

SEMINAR INTRODUCTION Biometrics is a rapidly evolving technologyFacilitates the automatic identification based on physical or behavioral characteristicsEliminates the need to memorize a password or carry some form of token

SEMINAR WHAT IS A BIOMETRIC ?Science and technology of measuring and statistically analyzing biological data that is represented in human by patterns unique to every individual Biometrics is a science of measuring the unique physical characteristics of a person such as voice, a face or a fingerprint. These personal features are analyzed and stored as bioprints in a reference database, on a smart card

Figure describing the process involved in using the biometric system

SEMINAR DETAIL ANALYSIS OF IRIS SCANNING

Iris scan takes about 30sec & 2sec for verificationA camera located at about 3 feet focuses on & scans iris from one sideThis scan is converted into a templateOnly phase information is used for recognizing iris as amplitude information is depends on extraneous factors

SEMINAR ADVANTAGES OF IRIS SCANNING

Iris pattern posses high degree of randomness,variability & uniquenessPatterns are apparently stable throughout lifeEncoding & decision making are tractableImage analysis & encoding time : 1secSearch period : 100000 iris codes/sec

SEMINAR DISADVANTAGES OF IRIS SCANNING

Small target (1cm) to acquire from a distance (1m)Located behind a curved, wet, reflecting surfaceObscured by eyelashes,lenses,reflectionsPartially occluded by eyelids, often droppingIllumination should not be visible or bright

Fingerprint Authentication a fingerprint impression is acquired

The next step is to locate these features in the fingerprint image, using an automatic feature extraction algorithm.

How does fingerprint identification work? The first step in fingerprint identification is collecting the fingerprint, named enrollment.

In this step, the applicant acquires the reference fingerprint for later authentication.

The reference fingerprint is called the template of the fingerprint

After the capture of the template, it can be stored in a database, on a token with 2D barcode, or in a smart card

At this point, the applicant is registered and the next stage is to compare the fingerprint with the template to the fingerprint read by the sensor.

After reading the fingerprint, the authentication system extracts the minutiae in the same way as it did during the enrollment process

Since the fingerprint is never captured in the same position, the verification algorithm must perform rotation and translation of the captured fingerprint in order to adjust the fingerprint minutiae with the template minutiae.
