Scho means ultrasonic finger beats. Attachment for reading finger readings: technical characteristics, classification, instruction on the test, specificity, installation and special features of operation

Finger bit rate sensors on the current day have gone beyond the premium segment of smartphones, the technology of additional hardware devices can be used in a relatively inexpensive middle-price range. In the hour of entering the market, technology has recognized significant evolutive changes, so your respect will be impressed upon the obvious on the market of fingerprint sensors due to the implications of the indications between them.

Optical scanners

The most advanced way of capturing and reducing finger beat. Both the name and the technology are based on optical images, on the basis of photographs, and special algorithms for the purpose of assigning unique messages on the surface, for example, humped or unique images, analogous

For the analogue of cameras in smartphones, some sensors may have specifically called out, what else, more other details will be available for processing with a scanner, so that you can move the line to the user. However, some sensors will recognize a higher contrast of the image, a lower camera. Name them included great number diod per inch for a clear view of objects in close proximity. At the moment of scanning the finger, the scanner is in the temper, so the optical scanners are also "on board" the light, as it sleeps before the hour is scanned. Choose an internal device to provide your smartphone with additional milimetry and negatively appear on the end-to-end form factor.

The head shortage of optical scanners is unreliable. With the help of my help, I can only use two images; good quality or piece by piece we turn it off with a beat. It’s not a good idea to use a similar type of scanner, but it’s not safe enough for the most important information.

New Year Fingerboard Sensors in Smartphones Mayut різні form and there are no optical scanners in them. For the analogy with the ear, the broadening of resistive sensor screens Optical scanners for this day can be installed in the most inexpensive hardware solutions. The need for security as much as possible zoomed the monophonic transition of smartphones to capacitor scanners.

capacitor scanners

The most widespread type of finger-beat sensors. The first name of the type is the head component, which, in a manner of speaking, is connected to the electronics - a capacitor. Replace the legacy of the traditional image of the video bit, capacitor scanners and capacitors for the collection of information about the video cards of an array of capacitors. Connect the building to the building electrical charge capacitors to the wiring board, then you can allow the vikoristovuvati for reading the details of the vidbit. The charge in the capacitors will change slightly for an hour until the finger is paid, and at the same hour of the prodigies, the charge will be overcharged without a change. To support the change, it is possible to integrate the lancet of the operational driver, by means of which you can record the signal from analog to digital with a converter.

The scanned digital information can be analyzed for the specific and unique parameters of the beat, which can be saved for later testing. Additional sensor is more foldable "fool", lower optical. It is hard to see the results on the images and even more smoothly, be it a piece of video: development materials viklichut change in the charge of the capacitor. A single riser for security can be used as a means of software or hardware security.

The staff of the door can reach a great array of such capacitors (hundreds, perhaps not thousands of capacitors in one scanner) For analogue with optical sensors, a larger number of capacitors will give a larger dialer of the scanner, and then press the switch.

Thanks to the large number of components in the lanterns of the capacitor scanners, it can be very expensive. In some early options, it was tried to try to reduce the number of required capacitors by means of the swipe scanners, as they adjusted the information from the smaller number of capacitor elements to the results of fingerprinting. The method of getting to the bottom is often needed for a successful scan. Happily, this year has been expanded more simple scheme sensor robots: reach a simple onslaught and decrease.

ultrasound scanners

New fingerprint technology, first presented in the warehouse of the Le Max Pro smartphone. An important role in this game was played by Qualcomm and Sense ID technology. For the actual collection of parts about the drive bead to the warehouse, the hardware platforms include ultrasound transmitters and pickups. An ultrasonic pulse is transmitted through a finger scanner. It is often transferred back to the sensor in the deposits of humps, which are sometimes unique for the skin.

Any microphone, when the signal is being read, is not transmitted, the sensor is replaced by a sensor, which can be mechanically stressed by turning the signal on the smaller sensor windows. Scanning for more than an hour allows you to read additional information, but you can also add a detailed trivial model of the scanned video beat. The trivial nature of the technology is to rob even more of a non-fired alternative to capacitor scanners.

Algorithms and cryptography

The majority of fingerprint sensors are based on even similar principles, alent components and software security can play a major role in the differentiation of products in terms of productivity and functionality, available to the residents.

The physical scanner supervises the microcircuit, which interprets the scanned information and transfers it in the required format to the smartphone processor. The definitions of the virobniks are easy to see one way of one for the speed and accuracy of the algorithms for identifying the key characteristics of the beat.

Call the ts algorithms to "whine" the place, de end the humps and lines, or the hump split into two. The selection of images is called a template or a detailed protocol for inserting a video. As soon as the scanned viewer has a number of such features, then the viewer will be insured as it is. Instead of changing the skin once a few times, adjusting the specificity to the pattern according to the number of needs for identifying the image of the numeric effort, in addition to helping to remove the marks in the center of the finger

Insanely, some information is guilty of trying to get at the annex and was given a code that could be compromised. Replacing the preservation of information of the corystuvach in the net, the ARM processors can hopefully take care of the physical microcircuits from the list of their technology Trusted Execution Environment (TEE) on the basis of TrustZone. The price of a safe deposit box can also be used for other cryptographic processes and without the need to get it from stolen hardware components, such as a winbit sensor, so that you can try to get over it for additional software forgetting. Access to the hardened information is not of a special nature, for example, the password can only be reset to the functions that lie in the API of the TEE clients.

Some solutions from Qualcomm are incorporated into the Secure MSM architecture, Apple calls a separate project "Secure Enclave", but all the sorts of things are based on one and the same principle - the information on the middle part of the processor, until you can not access it operating systems. Within the framework of the FIDO (Fast Identity Online) alliance, over-the-top cryptographic protocols have been broken up, allowing victorious devices to seize zones for authentication with a "login" and services without a password. You can also enter the site or an online store, you can see your finger, and your personal information when you never leave your smartphone. It is not possible to reach the transfer of digital keys to the server, but not biometric information.

Fingerprint sensors began to reach the endless alternative to remembering numerical passwords and names given development A secure mobile payment system means that scanners become more advanced and more useful tools to save the security in the future.

Quite once Qualcomm has announced that the ultrasonic fingerprint scanner can be used with metal, or with a flip display. The stench can also smell good and under water, as it is protected to the IP68 standard, with a large number of modern flagship outbuildings. Declared a robot through oil. At the same time, the sensor can clearly see your fingerprint. So, as long as you get ready, and pay oil on your phone - all one thing can be unlocked and wondered if you go for a recipe.

Tsikavim є the fact that sensors can be important to your heart rate. It is no longer necessary to reach for the sleeping chamber. There is a great deal of new possibilities for supplementary food safety. Also, an ultrasonic scanner can be used to scan fingers.

This technology allows the development of a mod scanner with metal or sklom, not shy for any special viruses. The company is unique, with ultrasonic sensors for fingertip bits, and with current and powerful processors Snapdragon 200, 400, 600 and 800 series, including the recently announced Snapdragon 630 and 660.

Identification of finger bits is one of the best ways to identify a human individual. For the accuracy of such a method, it is not necessary to scan the scan of the screen and to analyze the DNA. Finger beats are not as good as papillary ones on skins, which are unique for skin people and are formed in the fetus for 12 more times at once with the nervous system. At the same time, the genetic code of the child is poured into the children, the placement of the fetus in the mother, the harvesting of the mother before the hour of vaginosity, the camp of the middle class and the most senior officials. By simply my, papillary vizirunks - the process of being lost and dying on the shkіrі, so that one child becomes one of their own kind. To navigate in case of advanced epidemics in an hour, the students will be renewed, in order to deprive them of food for an hour, and, in an extraordinary way, a step of training. Like a great finger scanner on a smart phone, it's all about this year's release.

Any finger scanner has two functions: Rewrite the image of the display and convert each one to one with the other ones in the database. Optical scanners are used in modern smartphones. Smell follow the same principle, but small digital cameras. You know how to take care of the microcircuits, how to store up with light-sensitive photo-diodes and an autonomous illumination dashboard - matrixes of light-emitting diodes, like the ones that show up on your fingers.

When the lights are on, the photodiode fires an electric charge, which is stored in the memory for the maybutny sign. Falling as a result of consumption of light, the intensity of the color of the pixel changes. The number of pixels of high intensity and is set on the scanners with a finger mark. Before you start playing the video beats, the scanner inverts the brightness of the image, and the very brightness and clarity. As soon as it’s too dark, it’s triviality of the scanner’s window, and the process repeats itself.

In order to be able to display the feedback, it is necessary to analyze for the additional help of special software security. For identification of the peculiarities of papillary variations, software is used by vicorist folding algorithms. In all, there are three types of variations: arches, loops and curls. Having established the type of vizerunka, the scanner for identifying the end of the line of vizerunks, for example, the size and distribution - named minus. The stench itself is unique and it allows you to identify the owner of the owner on the swipe of the finger. The scanner is sure to put one on the skin mark: it breaks the video cards into small blocks of 9x9 pixels, the skin does not fit the same number of minutes. Coordinates of the revealed Minucii and іkh kuti orієntatsії are written into a vector. Because of the identical blocks from the scanner and signs from the base of the given ones, they are inserted, and if there are identical blocks in them, then the finger bits should be placed on the same owner. It is obvious that the scanners do not analyze the skin line of a vierunka: there is no smell of the same regularity in a small number of blocks, and similarity will be established by them.

There are two main types of optical scanners. The first to rob the mark of the required area of ​​the finger when dotting to the scanner. Tsey type vikoristvutsya in Apple smartphones, Fixing your iPhone 5s.

Another type of optical scanner is a finger swipe transmission. Win to rob a series of signs and programmatically interconnect. Such a scanner knows your Samsung Galaxy S5. Alle in the offensive models, there are substitutions for the first type, which is more handy, or more expensive due to the need for a larger matrix.

A small number of optical scanners є the strength of the obstruction and the podryapin. In addition, such a scanner can be fooled for the additional malfunction of the phalanx of the finger.

Not so long ago, the technology of reading beat bits of the bull was tied mainly with sci-fi films. Now, go to budget smartphone Xiaomi є fingerprint scanner The principle of yogo robotics is understandable for readers.

The finger scanner (Touch ID) allows the identification of the finger on the basis of a unique fingerprint. In the skin of a man, there is a powerful display and a "baby", which does not repeat itself in a type of identical twins.

The fingerprint allows you to identify a person, for example, if you are playing with people. Yak viyavilosya, the Touch ID function is also suitable for smartphones. In addition, you can steal your smartphone due to unauthorized access.

In Danish hour on the market there is a collection of types of scanners. All the stinks work for one and the same principle - the scanner reads the video cards of the owner of the smartphone and when you try to unblock one of these "babies", which are programmed in advance in the annex. As soon as the finger beats up, it will be unlocked. In іnshomu vipadku will appear about the pardon.

Tsіkavo, scho the scanners do not analyze all the little ones with a finger. Perevirayutsya deprived of deyakі from characteristic rice abo vіzerunkіv. Tse, for example, razgoluzhennya, razdvoєnnya or shaving off bits of fingers.

Scanning to transform the picture into the Temple (template), and by the algorithm to transform it into curves and lines. Tse allows you to revise the process of reversing on a shorter basis, but if you would need to analyze the entire image of your finger.

Algorithms to process the video bit rate, approximately 40%. In practice, there is enough for the identification of a particular corystuvach and for the maintenance of the efficiency.

Мінуцій (abo "Galton's points") - are unique for the skin finger of a dilyanka malinka shkiri (points), which show in some mice papillary lines get angry, split or shave.

Types of finger scanners

1. optical scanner"Knowing" the entire panel of fingers and vicorist CCD-matrix (as and more cameras) for the whole. In mice, de light do not come (comb), the matrix writes down the "black" pixels, flashing exactly the picture of the finger is displayed. Often, optical scanners may be constantly light-headed (light up light), so we can see through the image as much as possible.

2. Smart scanner- to replace the matrix, to make special miniature circuits of the capacitors (microsensors). If the lecture is a finger to the reader, the number of capacitors is mittєvo change. The most accurate and efficient optical scanners are more accurate and more efficient than optical scanners.

3. thermal scanner- it is similar to the microcapacitor in the same way as the microcapacitor; Such a scanner is unwise to fool an imitating finger (like a fragment with a shkinny cover).

4. ultrasound scanner- vicious phenomenon of diffraction, i.e. If my lecture, my finger before the sound of it, will start generating inattentive sounds for us. Behavior of sound bumps at the points of contact of the "comb" of the maidanchiks is displayed with the scanner for the first time, below the "depressions". This allows the ultrasound scanner to capture the exact image of your finger.

Is it more beautiful to scan your finger?

In the present hour, there are more Xiaomi smartphones in the market.

Touch function ID in smartphones, if it is even more secure, does not guarantee 100% security. With the help of the right technology and tools, you can beat the finger's thumbnail, which can fool the scanner.

The fingerprint scanner is a practical, non-budget smartphone. There are a lot of virobniks singing, but you can use fingerprint sensors not only manually, but forever.

All the sounds were made with the help of the smart technology for unlocking the smartphone, ale von can vikonuvatische bezlich brown functions... Bagato hto vvazhaє, bula vikoristan technology was given for the first time Apple company in the iPhone 5S. As a matter of fact, in the period from 2002 to 2011, about 30 telephones, equipped with a fingerprint sensor, were announced for sale. In 2011, Motorola launched a smartphone for the operation Android systems, on back krishtsi how to expand the fingerprint scanner. On the other hand, they practically lost their interest in attracting and new technology, and only those Apple spirits could turn the interest to it.

How do you run video scanners?

Є A number of types of scanners, the most suitable for the most popular optical ones. Most of the wines are of the male type - the wines are not only the budget ones, but the easiest ones in the implementation. The principle of robotic polarity in the "photographing" and remembering the finger beat. Such fingerprinting has a number of minus, and also on the quality and speed of the scanner, the complexity of the scanner, the cleanliness and readiness of the finger, as well as the appearance on the new mechanical items... Besides, it’s the very simplest to fool you.

Ultrasound scanners for offbeat giblets come for a change in between. Stink scan the surface of your finger for the help of sound hwil. This technology is more safe, the hour is less than that, the difficulty and efficiency on the screen are not scary. At the moment, a number of top smartphones from Chinese virobniks are equipped with a type of sensor.

Functions of the finger scanner

It’s not easy to forget, but a smart phone today is extremely important in the life of a practical skin people. The price is not just attitudes for healthy communication and writing about the occasion, but a reference list of special tributes, photos, tips, notes and financial information. All the money will be sent to the nadiynogo zakist, yak and will not preserve the fingerprint scanner. In such a rank, the first function of the field in the possibility rozlokuvannya smartphone.

Another function can be called access to special files... On some Android smartphones it is possible to power up the video bit not only when the add-on is unlocked, but when the add-on is displayed, for example, a gallery, a calendar or documents. In addition, such a function will be correct and for the provision of access to financial supplements... Just guess, did the kids talk, or the tanks in the online games, using smartphones of the fathers?

For some Huawei models, with an additional fingerprint sensor, you can responses to calls- you just need to put your finger to the scanner and finish rolling the cob. At first glance, the function is to be built by hand, ale, from the side, because it’s great to pick up the phone.

Payment in the Internet... For help special supplements you can go shopping in online stores, penny, Payment of utilities services that are very rich. With the help of the scanner, you can easily change the hour of the operation and confirm the payment by simply dosing fingerprints.

Transfer of tributes. The smartphone is equipped with a featureless function, one of which allows you to transfer a file from one attachment to the other "by chance", for example, via Bluetooth. If you do not enter the password again, you can confirm it using additional fingerprinting.

Vikoristovuchi scanner, you can turn on the alarm clock... The principle is that it’s just like that for all people who are overwhelmed with it — just as soon as the alarm sounds, if you put your finger on the sensor, and the signal is automatically picked up. Tilki do not forget to set up autorepeat, you can miss it.

What is the most advanced finger scanner?

Fingerprint sensors can rightfully be used as new ones. Protest, hackers are already in trouble. The very banal way of a pole is in the fact that you can create a photo vidbitka (for example, on a glimpse of a vase), razdrukuvati yo for help string printer i put it on the scanner. Tsei way can spratsyuvati only with the first generation of fingerprinting.

You will need to be smart enough to get rid of the bad luck with the silikon. Obviously, the methods are more similar to the butt of the movie, but all one is needed to be ready and take care of your smartphone.
