INTRODUCTION:-
“Biometrics is the identification or verification of human identity through the measurement of repeatable physiological and behavioral characteristics”
Biometrics can be sorted into two classes:
•Physiological
Examples-face, fingerprints, hand geometry and iris Recognition, DNA.
•Behavioral
Examples-signature and voice.
ABSTRACT:-
Characteristics of BIOMETRIC TECHNOLOGY:-
Universality means that every person using a system should possess the trait.
Uniqueness means the trait should be sufficiently different for individuals in the relevant population such that they can be distinguished from one another.
Permanence relates to the manner in which a trait varies over time. More specifically, a trait with 'good' permanence will be reasonably invariant over time with respect to the specific matching algorithm.
Measurability (collectability) relates to the ease of acquisition or measurement of the trait. In addition, acquired data should be in a form that permits subsequent processing and extraction of the relevant feature sets.
Performance relates to the accuracy, speed, and robustness of technology used.
Acceptability relates to how well individuals in the relevant population accept the technology such that they are willing to have their biometric trait captured and assessed.
Circumvention relates to the ease with which a trait might be imitated using an artifact or substitute.
CONCLUSION:-
Sony has developed a new biometric scanning technology, called ‘Mofiria’ that scans the veins in your finger in order to provide access to your laptop or PC. The scanner uses a CMOS sensor to capture scattered light within the finger veins, and compresses the date to allow it to be stored on laptops, or even cellphones.
There are many benefits to this new method, claims Sony. Firstly, this technology claims a high accuracy rate, with less than 0.1% false identification. Secondly, it takes a lot less time to scan the finger; it takes 0.015 seconds to scan on a computer CPU, and 0.25 seconds on a mobile phone CPU. Finger vein patterns are different between each person, between each finger and best of all, don't change over time.
This is a good step for computer security, and hopefully becomes more readily available in the near future.
