Biometric technology in the security and health sector

Biometric Systems

The term “biometric” is derived from the Greek words “bio” (life) and “metric” (to measure). Biometrics is the measurement and statistical analysis of people’s unique physical and behavioral characteristics. This technology is mainly used for identification and access control, or for identifying individuals who are under surveillance. Biometric technology is able to recognize a person on the basis of the unique features. These include their face, fingerprint, voice, keystroke, signature, DNA or iris pattern. It then imparts a secure and convenient method for authentication purposes.

The history of biometric technology

The earliest form of Biometrics appeared back in the 1800’s. Alphonse Bertillon, an anthropologist and police desk clerk, developed a method for identifying criminals that became known as Bertillonage. Bertillonage was a form of Anthropometry, a system by which measurements of the body are taken for classification and comparison purposes.

What are the advantages of biometric technology?

The obvious advantage of biometric technology compared to more conventional or traditional authentication methods, such as personal ID cards, magnetic cards, keys or passwords, is that it is intrinsically linked to an individual person and therefore not easy to break into.

Physiological biometrics

What is a facial recognition system?

Facial-Recognition-Technology

A facial-recognition system is capable of identifying or verifying a person from a digital image or a video frame. They work by comparing selected facial features from given image with faces within a database. You might have have bumped into this type of system on platforms like Facebook.

Nobody is going to steal your face (although it does change over time, reducing accuracy). A facial biometric security system can drastically improve your security because every individual who enters your premise will be accounted for. Any trespassers will be quickly captured by the recognition system and you would be alerted promptly. With a facial recognition security system, you can potentially reduce costs of hiring security staff.

With today’s technology, face ID technology is becoming more and more reliable. The success rate is currently at a high due to the developments of 3D facial recognition technologies and infrared cameras. The combination of these technologies make it very hard to trick the system. With such accuracy, you can have confidence that the premise is more secure and safe for you and your peers.

The setbacks for facial recognition are data storage & the fact that it needs many camera angles for accurate results.

How Biometric Attendance System Works

attendance

Biometric time and attendance systems have become popular in the business world today when it comes to tracking employees and their attendance. These systems are easy to use, easy to install and track data regarding employees for management to analyze.

Attendance systems prevent employees from clocking in for one another. Previous methods included a time-clock, a sign-in sheet and swiping an ID card. Attendance systems greatly reduce employee time theft.

Biometric finger print scanner

A Physiological finger Scanner works on two basic principles.

  • First, it takes an image of a finger.
  • Then finger scanner saves specific characteristics of every unique finger in the form of biometric encrypt key.

Actually finger print scanner never saves images of a finger only series of binary code for verification purpose.

Banking and payment card information are a perpetual target of cyber-criminals. They know that a right combination of numbers can empty card holder’s account and fill theirs, so they do everything they can to steal credit card information.

What you should know about biometric credit cards

The Biometric credit card that was introduced by Mastercard looks like any other plastic chip and pin credit card, except the fact that it also has a fingerprint sensor embedded on it. Mastercard announced the biometric card on April 20, 2017. This announcement marked the day in history of biometrics as well as payments cards to add a biometric authentication layer to secure credit cards and prevent fraud. With biometric card, customers no more need to enter their PIN, just the touch of your fingertip is enough to authenticate a payment.

 

DNA Biometric Technology

DNA is one of the most commonly used biometric technologies around the world. The first reason is that a lot of people agree on that DNA is the most accurate technology that never fails. Of course, there is no such thing as 100% accurate because something can go wrong at any time and errors happen. however, when they happen it is usually recognized as an error and the tests are done once again to get the correct results.

This technology is commonly used because this is the only biometric process that allows us to link relatives to a person. This means that with a proper DNA test we are able to tell if two people are related.

DNA is very similar to the fingerprint biometric because it can be also found anywhere. A fingerprint can be found anywhere if a person has touched something, a DNA can be easily found if you see blood, urine or any other liquid that has come from a human. One more cool thing about DNA technology is the speed of it. This means that the results of a DNA test will be available in as little as 90 minutes. This gives a huge advantage, for example, some crime investigator and police who need to track down a killer. Getting fast biometric results is a key thing for people that are solving crime cases.

Iris recognition

Iris recognition biometric systems apply mathematical pattern-recognition techniques to images of the irises of an individual’s eyes. The Iris is an organ whose structure remains stable throughout life. Thus it serves as a very good biometric for establishing identity of an individual. Because of its very low margin-of-error and fast speed, iris recognition is now one of the most trusted ways of confirming the identity of a person. Iris are different even for identical twins!

Behavioural biometrics

The search is on to find a uniquely identifying characteristic not of what you are, but of what you do. Behavioral biometrics involves analyzing someone’s walking style, signature, voice etc.

Today’s behavioral biometrics, though, go way beyond signature, voice and speech, as they are able to analyze multiple data and end-point interactions such as hand-eye coordination, pressure, hand tremors, navigation and other finger movements. They can assess how well people know the information they are entering and how familiar they are with the application they are using by how they engage with it. Behavioral biometrics are very attractive since they are completely passive and generally do not require a change in the user experience.

Voice recognition technology is used to produce speech patterns by combining behavioral and physiological factors that can be captured by processing the speech technology. The most important properties used for speech authentication are nasal tone, fundamental frequency, inflection, cadence. Voice recognition can be separated into different categories based on the kind of authentication domain, such as a fixed text method, in the text dependent method, the text independent method and conversational technique.

Factors to Consider in Choosing the Best Biometric Modality

The success of a biometric system often depends on choosing the right biometric modality. Careful research that includes rigorous comparisons of modality strengths and weaknesses is an important element to help select the right hardware. Factors to consider in the comparison may include: specifications, convenience, usability, acceptability, effectiveness, and budget.
