What is Biometrics? Biometrics are automated methods of recognizing a person based on a physiological or behavioral characteristic. Among the features measured are face, fingerprints, hand geometry, handwriting, iris, retinal, vein, and voice. Biometric data are separate and distinct from personal information. Biometric templates cannot be reverse-engineered to recreate personal information and they cannot be stolen and used to access personal information.
Using a unique, physical attribute of your body, such as your fingerprint or iris, to effortlessly identify and verify that you are who you claim to be, is the best and easiest solution in the market today. That is the simple truth and power of Biometrics Technology today. Although biometric technology has been around for many years, modern advances in this emerging technology, coupled with big reductions in cost, now make biometrics readily available and affordable to consumers, small business owner, larger corporations and public sector agencies alike.
Identification reliability is at a very high level, and nearly all fingerprints can be identified. For example, the fingerprints of persons working in specific professions can be so damaged that a sufficient number of identification points cannot be read. Such professions include those where the skin on the fingertip is repeatedly burned or corroded by chemicals. Fingerprints are restored after single damaging incidents, so a few injuries have no effect fingerprint identification.
People who have transferred to using fingerprint identification do not usually wish to return to previous methods of operation.
The ease and simplicity of use are the main reasons for customer satisfaction. We can therefore highly recommend fingerprints as a method of identification. Deltabit products can utilise fingerprints for identifying patients in healthcare. In addition, Deltabit Dooris is a product that replaces keys with fingerprint identification, and Deltabit Gatekeeper is a fingerprint-operated access-control system for companies.

For which purposes is fingerprint identification suited? What benefits does fingerprint identification provide? Next Page ». Automated fingerprint matching is a complex process based on rules coded in a programming language. These sets of rules or instructions are called algorithms. They are time-tested, Free Fingerprint Scanner Applications vs. Using a fingerprint scanner is a straightforward deal, register your finger once and use it every time you need to authenticate.
Be it mobile phones, access control This is hardly surprising as most fingerprint recognition systems are Danny Thakkar Fingerprint Recognition , Fingerprint scanners.
In identity management space, things are quickly moving towards a password free environment. The technology has also moved on a lot from its early iterations, becoming faster and more accurate at capturing your fingerprint. Stay secure: 15 best antivirus apps and best anti-malware apps for Android. Optical fingerprint scanners are the oldest method of capturing and comparing fingerprints. As the name suggests, this technique relies on capturing an optical image — essentially a photograph.
It then uses algorithms to detect unique patterns on the surface, such as ridges or marks, by analyzing the lightest and darkest areas of the image. Just like smartphone cameras, these sensors have a finite resolution. The higher the resolution, the finer details the sensor can discern about your finger, increasing the level of security.
However, these sensors capture much higher contrast images than a regular camera. Optical scanners typically have a very high number of diodes per inch to capture these details up close. As the technology is only capturing a 2D picture, prosthetics and even pictures of good quality can be used to fool this particular design. As such, the industry has moved on to more secure hybrid solutions. With an increasing demand for tougher security, smartphones have unanimously adopted superior capacitive and optical-capacitive hybrid scanners.
These scanners use optical fingerprint data, combined with capacitive sensing to detect a real finger. The falling cost of technology has made these alternatives viable for mid-range products too.
With the move towards bezel-less displays, smaller optical modules are making make a comeback. They can be embedded underneath the display glass and only require a small area footprint.
Some models on the market can operate successfully under 1mm of glass and with wet fingers — something that messes with capacitive alternatives. Hybrid optical scanners are here to stay. Another common fingerprint scanner type used today is the capacitive scanner. Capacitive scanners grew to prominence because of their additional security benefits.
Again the name gives away the core component — the capacitor. Instead of creating a traditional image of a fingerprint, capacitive fingerprint scanners use arrays of tiny capacitor circuits to collect data.
As capacitors store electrical charge, connecting them up to conductive plates on the surface of the scanner allows them to be used to track the details of a fingerprint. Conversely, an air gap will leave the charge at the capacitor relatively unchanged. An op-amp integrator circuit is used to track these changes, which can then be recorded by an analog-to-digital converter.
