What is Biometric Authentication ?| What is Biometric ?| How Biometric Works ?|What is Biometric System ?.

Hello and welcome to our ongoing series about enterprise technology. Today we’re looking at biometric authentication, the latest and perhaps most innovative development in identity and access management. How does it work? And should your enterprise consider deploying it? Traditional biometric authentication uses the distinct biological or physiological characteristics of users to verify their requests.

A biometric authentication solution stores the biometric data in a secure database and then compares inputted biometric factors to confirm the login. The benefits of this approach over text-based passwords become apparent almost immediately. There’s no way for anyone to “forget” their biometric factors, like you might with passwords, as you’re usually attached to them. Biometrics can’t be guessed or cracked in the same way as passwords, and as long as they remain securely stored, can’t be stolen either. Also, biometrics can facilitate workflows by allowing for more instantaneous logins and by freeing up your IT security team from having to do continual password retrievals.

Previously, biometric authentication was the stuff of science fiction, depicted in film and television as advanced, expensive and rather bulky technology to convey over-the-top security to the audience. However, recent innovations in biometrics allow enterprises and users to embrace this new development in identity management. And if you’re among the 29% of Solutions Review viewers who are watching this video on a mobile device, there’s a good chance you used biometrics to unlock it; as an estimated 429 million smartphones offer biometric authentication today.

Actually, your enterprise can also use the proliferation of mobile devices to your advantage. Enterprises with biometric authentication solutions can often sync with employees’ own mobile devices, allowing them to undergo authentication through them. This can become a huge bonus to workflows and to remote employees, as it increases security and reduces time at the login portal. Typically, people think of biometrics as using purely physical factors, such as fingerprinting, retina scans, facial recognition, and voice recognition.

While these all play a role, biometric authentication also incorporates new dimensions such as behavioral biometrics. This performs continuous authentication by ensuring users (who passed the initial login portal) type, act, and otherwise conduct themselves according to baseline behaviors. Users who don’t can be barred from further acting until their identity can be otherwise verified. Biometrics are often used as a major component of modern multi factor authentication.

In turn, biometric authentication benefits from the other layers of security found in MFA; including geofencing, time of request monitoring, and hard tokens. The more security layers that stand between users and access, the more difficulty hackers face trying to breach your network. While biometric authentication provides a stronger single-factor authentication method than passwords, relying on any one security layer alone can put your enterprise in jeopardy. Biometric authentication should be a key consideration for any enterprise’s cybersecurity, but it should only serve as one part of your overall identity management platform.

That’s all for now. For more information about Biometric Authentication, cybersecurity news, or our comprehensive Buyer’s Guides, visit Solutions And be sure to join us next time when we explore the top multi factor authentication capabilities.

From the combat zone to the corporate office, from the airport to the ATM - knowing who's really who is a big security concern. Traditionally, a person might enter a password or pull out a driver's license or passport as proof of identity. But increasingly, identification and authentication can also require an eye scan or a well-placed hand.

Go ahead and turn. It's a science known as biometrics, recognizing individuals based on their physical or behavioral characteristics. The structure of the face, the geometrics of the hand, the ridges of a fingerprint, the patterns in an iris - every person carries multiple human traits that are a unique form of personal identification.

The primary advantage of a biometric trait is that it belongs to that individual. You Are implicitly connected to it, unlike passwords or tokens or passports, which are external to an individual. Arjun Ross is a Computer Science and Electrical Engineering professor at West Virginia University, one of three institutions where the National Science Foundation is helping to fund a coalition of biometrics research sites. The Center for Identification Technology Research, or CITeR, as the coalition is known, is an example of the important role that public and private funding can play in the innovation process. The National Science Foundation does offer seed funding.

But that is augmented with the funding from these corporations and government agencies. CITeR affiliates funded Ross's 2005 research with Dr. Reza Derakhshani, who was at the University of Missouri in Kansas City. Iris recognition systems process the full iris, so when the eye's gaze is off-center, only a portion of the iris is seen, and recognition is hindered. Ross and Derakhshani proposed the idea that the sclera, the white part of the eye, might be an additional biometric trait that could be used for identification.

We asked ourselves what type of information can we extract from the sclera in order to perhaps improve the performance of classical iris-based systems. First, Ross and Derakhshani collected digital images of eyes from dozens of subjects. Then they separated the sclera from the pupil and the iris to search for unique features. We began to see the features that were on the surface of the sclera, but also the conjunctival vasculature, the vein pattern that is evident through the sclera. So we started developing algorithms that can be used to extract features.

Computer algorithms are step-by-step instructions that tell the computer what to do. With fingerprint recognition, they are used to extract features called minutia points, the unique points in the fingerprint ridge where it ends or splits in two. With iris recognition, they convert the unique iris patterns into a binary code, made up of zeros and ones, like a barcode of the eye. So when we say algorithms, really, were talking about image processing algorithms, algorithms that the computer program can use in order to extract features that can subsequently be used for matching purposes.

With sclera recognition, the algorithms extract features from the sclera surface and vein patterns. As they hoped, the sclera proved to be useful in identification. Blood vessels, like fingerprints, remain stable throughout life. The computer program was able to compare and match this information. We began to notice that the similarity between two images of the same person was much more than between two different individuals. With the university's help, Ross and Derakhshani filed for a patent, which was granted by the United States Patent and Trademark Office in 2008.

Simona Crihalmeanu, a research associate on Ross's team, based her own research on the patent, developing different ways to extract and match features found in the sclera. I think she has really contributed in taking this research to the next level by developing new algorithms for feature extraction and matching, as well as the possibility of combining the iris with this sclera. The research also caught the attention of a commercial venture, Eye Verify, which has licensed the patent for mobile applications. We have to keep moving forward, looking at new ways to solve old problems. Because, what was unsolvable a few decades ago might be solvable now.

Solving old problems takes innovative thinking, and because of dedicated funding, researchers like Arjun Ross have been able to work on new solutions - with an eye toward the future.

Everything You've Ever Wanted to Know About Electricity: A guide around electronics and how to go about it. |

tale about world preoccupied with material possessions. 
It's tale about broken system. 
We're destroying the environment, destroying our other, and we're not even having fun. 
The good news is that if we grasp the system, we may discover several opportunities to intervene and turn these problems into solutions. 
couldn't find my computer charger the other day. 

My computer provides me with access to my work, friends, and music. 
So went into every drawer, even the one where this was kept. 
I'm sure you have one as well, tangle of outdated chargers, the sad relics of bygone era of gadgets. 
How did accumulate so many of these items? 
It's not like I'm constantly on the lookout for the next technology. 
My old devices broke or grew outmoded to the point that couldn't utilize them. 
And none of these ancient chargers are compatible with my PC. 

This isn't simply case of bad luck. 
It's terrible design. 
It's what call "designed for the dump." 
Isn't it ridiculous to say "Designed for the dump"? 
But that makes perfect sense when you're trying to sell lot of items. 
It's vital strategy for the electronics manufacturers. 
It is, in fact, critical component of our entire unsustainable material economy. 
Creating items that can be thrown away fast is referred to as "design for the dump." 

Electronics today are difficult to upgrade, easy to break, and difficult to repair. 
My DVD player broke, so took it to repair shop. 
Just to glance at it, the repairman demanded $50! 
Target has new one for $39. 
Gordon Moore, the semiconductor pioneer and gigantic brain, predicted in the 1960s that electronics designers would be able to double processing speed every 18 months. 
He's been correct so far. 
Moore's Law is the name given to this phenomenon. 
However, the employers of these brilliant designers managed to get it all mixed up. 

They appear to believe that Moore's Law dictates that we must replace our old equipment every 18 months. 
The difficulty is that our use of these items for 18 months is only blip on the radar of their entire existence. 
And it's here that these slum designers aren't simply hurting our wallets. 
They're causing global poisonous disaster! 
Electronics, you see, begin where most things do: in mines and factories. 
Many of our devices are made up of over 1,000 different materials that are transported in from all over the world to assembly sites. 

Workers there use variety of dangerous chemicals, including PVC, mercury, solvents, and flame retardants, to turn them into products. 
Today, this frequently occurs in remote locations that are difficult to monitor. 
But it used to happen near my home, in Silicon Valley, which is one of the most polluted regions in the United States because to the electronics industry. 

According to IBM's own data, computer chip employees had 40% more miscarriages and were substantially more likely to die from blood, brain, and kidney cancer. 
The similar trend is beginning to happen in other parts of the world. 
The high- 
tech business, i
turns out, isn't as spotless as it appears. 
So, after hazardous journey around the world, the device lands in my hands. 
For about year, adore it, and then it begins to stray from its prominent position on my desk or in my pocket. 
Perhaps it spent some time in my garage before being discarded. 

takes us to disposal, which we consider to be the end of product's useful life. 
But, in reality, it's simply moved on to join the mounds of e- 
waste we generate
 every year. 
Remember how poisonous chemicals were crammed into these devices? 
Toxics in, toxics out, is the simple rule of production. 
Computers, cellphones, televisions, and other electronic devices are just waiting for us to dispose of them, releasing all of their poisonous contents. 
Even as we use them, some of them are slowly releasing this information. 
People are replacing their outdated, bulky TVs with high- 
definition flat screens. 
They each contain around pounds of lead. 

As in, you've been poisoned by lead! 
As result, practically all of my e- 
waste either end
up in landfill or is flown overseas to garage workshop in Guiyu, China, where it is recycled. 
I've been to number of these so- 
called recycling fa
Workers sit on the ground, wearing no protective clothing, cracking open devices to extract the valuable metals within and throwing or burning the pieces that aren't worth anything. 

So, while I'm working on the new gadget, my previous one is poisoning families in Guiyu, India, or Nigeria. 
We generate 25 million tonnes of e- 
waste each year, 
which is either thrown, burned, or repurposed. 
And that recycling is anything but environmentally friendly. 
So, are the geniuses who design these technologies wicked geniuses as well? 
don't believe so, because the difficulties they're causing are carefully concealed even from themselves. 

Because of this, the firms for which they work keep these human and environmental costs hidden from view and off their books. 
It's all about externalizing genuine production costs. 
Workers pay with their health instead of employers paying to make their workplaces safe. 
Rather than paying for redesign that uses fewer hazardous materials, the villages pay by losing access to safe drinking water. 
Companies can continue to design for the dump by externalizing costs; they keep the profits while everyone else pays. 

When we comply, it's as if we're gazing at this poisonous waste and telling businesses, "You made it, but we’ll deal with it." 
have better idea. 
"you made it, you deal with it" perhaps? 
Isn't that better explanation? 
Imagine if, instead of building up poisonous e- 
waste in our garages and
 on the streets of Guiyu, we sent it to the CEOs who created it. 
You can bet they'd call their designers and demand that they stop designing for the landfill. 

"Extended Producer Responsibility" or "Product Take Back." is the process of forcing businesses to deal with their e- 
It would b
cheaper for them to build longer- 
lasting, less hazardou
s, and more recyclable items in the first place if all these obsolete electronics were their problem. 
They could even make them modular, so that if one part breaks, they can simply send us replacement rather than returning the entire ruined mess. 

back laws are already b
eing enacted throughout Europe and Asia. 
Many towns and states in the United States are enacting comparable legislation, which must be safeguarded and improved. 
It's time to enlist the help of these geniuses. 
We are launching race to the top where designers compete to develop long- 
lasting, to
free items, t
hanks to take- 
back regulations and c
itizen action to demand greener products. 

So, how about green Moore's law? 
How about halving the use of harmful chemicals every 18 months? 
Will the number of poisoned workers continue to fall at faster rate? 
We need to set challenge for these designers so that they may do what they do best: innovate. 

Some of them have already realized they're too brilliant to be trash designers and are working on developing computers without PVC or harmful flame retardants. 
Guys, you did fantastic job. 
But there's more we can do. 
We can ensure that our e- 
waste is not sent t
underdeveloped countries when we take it to recyclers. 
We can also choose greener products when we do need to acquire new electronics. 
However, we will never be able to shop our way out of this difficulty since our options inside the store are constrained by the decisions made by designers and policymakers outside of the store. 

That is why we must band together with others to demand stricter regulations on dangerous chemicals and the prohibition of e- 
waste exports
There are billions of individuals who want to get into the amazing web of knowledge and enjoyment that electronic devices provide. 
But it's access they're after, not all that hazardous waste.  

So let's get our heads together and establish an electronics business and global civilization that is built to last, rather than sending the old design for the trash mentality to the garbage where it belongs.
