Nova Industries IP platform for physical access control
Opens the door to the future
With our Access Control Systems, we’re introducing a new level of freedom for physical access control.
Traditional proprietary systems mean limited options, central control units with often complex and expensive cabling, as well as restricted integration and scalability. Now, with Our Access Control Systems, there’s finally an open, easy-to-use and future-flexible alternative for physical access control.
Our systems comprise of non-proprietary platform for access management. It meets requirements for both small installations and advanced enterprise systems, offering a simpler, smarter, more streamlined alternative — whether you need to install one door or 1,000.
A physical access control solution that matches your pace – ZKTeco
We give you full flexibility in scaling up your solution. From adding a single door in a small office to integrating video surveillance in a large-scale facility, our ZK solutions allows you to grow at your own pace.
Biometrics is the science and technology of measuring and analyzing biological data. In information technology, biometrics refers to technologies that measure and analyze human body characteristics, such as DNA, fingerprints, eye retinas and irises, voice patterns, facial patterns and hand measurements, for authencation purposes.
Authentication by biometric verification is becoming increasingly common in corporate and public security systems, consumer electronics and point of sale (POS) applications. In addition to security, the driving force behind biometric verification has been convenience.
Biometric devices, such as fingerscanners, consist of:
- A reader or scanning device
- Software that converts the scanned information into digital form and compares match points
- A database that stores the biometric data for comparison
To prevent identity theft, biometric data is usually encrypted when it’s gathered. Here’s how biometric verification works on the back end: To convert the biometric input, a software application is used to identify specific points of data as match points. The match points in the database are processed using an algorithm that translates that information into a numeric value. The database value is compared with the biometric input the end user has entered into the scanner and authentication is either approved or denied.
Identification by fingerprints relies on pattern matching followed by the detection of certain ridge characteristics, also so known as Galton details, points of identity, or minutiae, and the comparison of the relative positions of these minutiae points with a reference print, usually an inked impression of a suspect’s print. There are three basic ridge characteristics, the ridge ending, the bifurcation and the dot (or island).
Identification points consist of bifurcations, ending ridges, dots, ridges and islands. A single rolled fingerprint may have as many as 100 or more identification points that can be used for identification purposes. There is no exact size requirement as the number of points found on a fingerprint impression depend on the location of the print. As an example the area immediately surrounding a delta will probably contain more points per square millimetre than the area near the tip of the finger which tends to not have that many points.
In image 1 we see part of a fully rolled fingerprint. Notice that the edges are cut-off so you can safely assume that this is not a fully rolled impression. If you take a look at image 2 you can see that I have sectioned out the centre portion of this impression and labelled 10 points of identification. That was not all the points found but simply the ones that could be mapped easily without cluttering up the image.
First, image 1 and image 2 are both taken from the same image. In real life you would have impressions made at separate times and subject to different pressure distortions. Secondly, these images are relatively clean and clear where many of the actually crime scene prints are anything but clear. Last you have to consider that this is an easy comparison because you are blessed with having a core pattern and a delta when in some cases you may have a latent that could be a fingertip, palm or even foot impression.
