Introduction of automatic fingerprint identification system, fingerprint system functions

Now fingerprint recognition technology has been widely used, so the device fingerprint system has also become a hot development. Many enterprises and institutions will customize their own identification systems, but because of the lack of professional knowledge, it is easy to step into a minefield when customizing the fingerprint recognition system of the device, and then let's talk about the details that should be paid attention to in this regard. First, in fact, when it comes to the customization of the device fingerprint system, the first thing to mention is the professional ability of the customization company.

Since it is a custom device fingerprinting system, it is natural to make sure that there are fingerprint recognition professionals in the team, for example, many people do not know that there are many ways to fingerprint recognition, and each method has its own equipment and technology, so this should be taken into account when customizing the program. Second, there is an increase in the number of customization channels for device fingerprint systems, and there is also one of them....

The fingerprint recognition system is a typical pattern recognition system, which includes modules such as fingerprint image acquisition, processing, feature extraction and comparison. Fingerprint images of living individuals can be captured by means of a special fingerprint scanner. At present, fingerprint collectors mainly include in vivo optical, capacitive and pressure-sensitive.

For technical indicators such as resolution and collection area, the public security industry has formed international and domestic standards, but there is still a lack of unified standards. According to the area of fingerprint collection, it can be roughly divided into rolling fingerprint and plane fingerprint, and the public security industry generally uses rolling fingerprint. In addition, fingerprint images can also be obtained through scanners, digital cameras, etc.

Summary. Hello, I am glad to answer for you, the functions of the fingerprint system are as follows: 1. Fingerprint answer**; As we all know, when we need to answer, we generally swipe the mobile phone screen directly to answer, but in fact, we can also use fingerprint sensing to realize the operation of answering, which is also very good.

2. Fingerprint to open the notification panel; When we use our mobile phones, we all use the mobile phone screen to swipe down to call up our notification panel, but do you know that we can also call up the notification panel through our fingerprint? We only need to swipe down at the fingerprint sensor to also bring up the notification panel, which is very simple. 3. Fingerprint photographing; As we all know, when we can't press the shutter on the phone screen to take pictures, we can help us take pictures by pressing the volume button on the side, but we can also take pictures by placing our fingers at the fingerprint sensor, which is also very convenient.

4. Fingerprint browsing**; When viewing**, we can also directly place our fingers at the fingerprint sensor, and then switch browsing by swiping left and right**, the masses who don't know the truth will still think it's amazing Fifth, stop the alarm clock; When our phone alarm goes off, we can't turn off the phone alarm accurately. But in fact, we can also turn off our alarm clock through fingerprint sensing, which is simply fast and ruthless.

Can you be more concise?

Fingerprint readers read fingerprints in a number of different ways, but the basic principle of capacitive sensing technology is that it conducts a fingerprint image based on changes in resistance on the surface of a living finger — note the word "live." **The cells of the epidermal layer, including the epidermal layer of the fingers, are non-living. Peeling off the epidermal layer of non-living cells reveals the first layer of living cells, which have a certain amount of resistance.

They also form a specific shape on the surface layer – the common fingerprint ridge and groove. The combination of the specific electrical qualities in the cell and the arrangement of the cells allows the resistance of the surface to be measured and the variation is unique. This is how a capacitive reader works – it first reads the changes in the resistance of the living epidermis of the finger and then conducts a map of the finger showing those changes.

The diagram looks just like a standard fingerprint image displayed by a police officer. The resistance change plot is called the fingerprint image. Once a fingerprint image is generated, it is saved, or compared to another fingerprint image to determine if they are identical.

Capacitive sensor technology dominates the fingerprint world; All other fingerprint recognition technologies are technology followers. The technology is also very mature, stable and reliable, and is one of the most inexpensive fingerprint sensing technologies on the market today. Software Name:

Fingerprint recognition technology.

BAI surgery mainly involves four functions:

Read fingerprint images, extract features, save DAO data, and compare. The image of the human fingerprint is read through the fingerprint reading device, and then the original image is preliminarily processed to make it clearer, and then the characteristic data of the fingerprint is established through the fingerprint recognition software. The software finds data points called "minutiae" from the fingerprint, i.e., the coordinate locations at the forks, terminations, or circles of the fingerprint lines, which have more than seven unique characteristics at the same time.

Typically there are an average of 70 nodes on a finger, so this method yields about 490 pieces of data. This data, often referred to as templates. Through the computer fuzzy comparison method, the templates of the two fingerprints were compared, and their similarity was calculated, and finally the matching results of the two fingerprints were obtained [5-6].

Acquisition devices (i.e., imaging devices) are divided into several categories: optical, semiconductor sensors, and others.
