Providing a secure authentication system has led to

rise in developing many biometric systems.

Biometrics can be defined as recognizing andidentifying a person based on physiological or

behavioral characteristics.

Biometrics is replacing passwords.

In this technology ONES dorsal hand is used as the

PASSWORD for verification.

The veins present in the hand of the individual arescanned & verified thus providing the access.

Dorsal Hand vein authentication has a high level of

authentication accuracy due to the uniqueness and

complexity of vein patterns of the palm.

Unlike the skin, through which near-infrared light

passes, deoxygenated hemoglobin in the blood flowing

through the veins absorbs near-infrared rays, causing it

to be visible as black regions to the scanner.

Arteries and capillaries, whose blood contains

oxygenated hemoglobin, which does not absorb near-

infrared light, are invisible to the sensor, hence wechoose VEINS.



5/17

An individual's hand vein image is converted byalgorithms into data points, which is then compressed,

encrypted, and stored by the software. person when

ever access it, the data is compared with stored one,

thus verification is done.

First the individual places his hand beneath the ir

camera, thus the camera takes the VEIN IMAGE and

compares it with the pre-registered one with the help of

INFRA RED RAYS.

If there is a match then access is allowed, if not accessis denied.

This system is not at all dangerous. A near infrared ray

is a component of sunlight, whose effect is much lessthan walking in sunlight.



8/17

The lighting of the infrared ray is controlled depending

on the illumination around the camera.

The camera captures the vein image given that hand is

placed in the right area.

The software matches the translated vein pattern with

the registered pattern, while measuring the position and

orientation of the palm by a pattern matching method.



9/17

Implementation of a contactless identification system

enables applications in public places or medicalfacilities.

The contactless feature of this device makes it suitable

for use where high levels of hygiene are required.

Eliminates any hesitation people might have about

coming into contact with something that other people

have already touched.



10/17

This technology system had a false rejection rate of

0.01% (i.e., only one out of 10,000 scans were

incorrect denials for access)

False acceptance rate of less than 0.00008% i.e.,

incorrect approval for access in one in over a million

scans.



11/17

No two people in the world share a dorsal hand vein

pattern - even those of identical twins will differ.

Even if you have registered your profile as a child, theimage will still be valid as veins are established in

utero (before birth).



12/17

Two products are in great demand in the general

market. One is for a physical access control unit, otheris a logical access control unit.

Physical access control unit can be used to control

entry and exit for rooms and buildings.

Logical access control unit can be used to protect input

and output of electronic data.



13/17

No more problems of forgotten passwords and id codes

- biometrics is the technology taking care of it.

Apart from other techniques like IRIS scan in whichCataract replacement, Finger scan during Injuries etc

can be an disadvantage, this technique has no problems.



14/17

Very Economical

Highest factor of Security

One time registry and usage throughout life

More advantageous than other Biometric techniques



15/17

Management in healthcare

Operator authentication

Owner authentication

Attendance authentication



16/17

Biometric technology has been around for decades but

has mainly been for highly secretive environments with

extreme security measures.

The above article gives a snapshot of the dynamics in

the emerging biometric market, and stands apart from

other techniques available and also a bit more

advantageous.
