How does the fingerprint scanner work on the Samsung Galaxy S5? Samsung galaxy s5 fingerprint.

Apple rocked the industry once again last September mobile devices thanks to the biometric sensor touch ID set in . Even then it was obvious that competitors would soon begin to act in this direction. It didn't have to wait too long - the new Samsung flagship, Galaxy S5, is also equipped with a fingerprint scanner. It remains to determine whose technology and its implementation is better and more convenient for the end user.

YouTube user Tanner Marsh set out to compare fingerprint scanners in iPhone 5s And Galaxy S5. The comparison was made on several parameters, including ease of use and ease of setup, as well as the direct use of the scanner in everyday use.

It is best to start the comparison with technology. We are talking about Touch ID, dwelling not only on the design of the biometric sensor, but also on the algorithm of its operation, as well as some aspects. In the case of the Galaxy S5, there is no such information yet, so the comparison turned out to be rather primitive. The iPhone 5s uses a small fingerprint scanner, combined with the Home button and protected by a sapphire crystal. In the Galaxy S5, the scheme is largely preserved, only to activate the device you do not need to press the button, but swipe your finger from the bottom of the screen to the elongated key below it.

Hence the differences in the process of creating fingerprints in the device's memory. In the case of Apple smartphone the user needs to put his finger on the button several times at different angles so that various possible combinations of future touches are recorded. In the case of a Korean device, you will have to perform the swipes described above. Here the first difficulties arise. The scanner in the Galaxy S5 is not always accurate. For it to work, the finger must fall exactly to the center of the key. In addition, as Marsh notes, this process is very difficult to manage with one hand due to the direction of the gesture and the size of the device.

Both iPhone 5s and Galaxy S5 have password-protected access to fingerprint management. You can also rename, delete or add new fingerprints there. In terms of using a fingerprint scanner, an Android smartphone has certain advantages. For example, you can make payments through PayPal using your fingerprint and without entering a password. A similar picture is observed in most of the mobile operating system from Google, while in iOS, password replacement is available only when you purchase an application in the App Store.

IN this moment it's too early to talk about the success or failure of the biometric sensor in the Galaxy S5. The device has yet to undergo a real test by millions of users. So far, questions are raised by the design and features of using a fingerprint scanner. By Android functionality ahead. Apple is probably preparing a serious response in iOS 8. [MacRumors]

Rate.

If you have already acquired new iPhone 5s, you probably know that one of the main technical differences of this device from previous models is the biometric sensor built into the Home button, in other words.

In this article, we will briefly talk about how to activate the fingerprint unlock feature on your smartphone.

By the way, the fingerprint scanner in the iPhone 5s, ie. Touch ID technology, in accordance with the manufacturer's terminology, is considered one of the most useful "chips" presented during the existence of Apple smartphones.

And although Touch ID in its current form has a number of limitations, the fact remains that Apple is once again raising the technological standard of modern smartphones.

But today is not about that. So, How to set up Touch ID on iPhone 5s? In fact, everything is simple:

1. Go to Settings and select General

3. Click the Fingerprints tab.

4. Click the My thumb tab.

5. In the “Place Your Finger” window that opens, we read the instructions and act. You won't have to work much. All you need to do is put your finger (any of your choice) several times on the Home button at different angles. The scanner reads the fingerprint in real time, the corresponding image will appear on the screen. You will need to move your finger until the fingerprint scanning procedure is completed. By the way, a clean and dry finger should be provided to the smartphone for scanning, otherwise the scanner may not work.

To the point:

6. The smartphone will notify you separately about the successful completion of the scan:

7. To check the validity of the biometric password, just return to the previous screen and put your finger on the Home button. Next, you should block by pressing the button and then with the finger whose fingerprint was scanned, press the Home button. Your iPhone 5S will unlock instantly.

The Touch ID system in the iPhone 5S provides for the use of more than one fingerprint to unlock the smartphone. To add another fingerprint password, do the following: :

1. Go to Settings and select General.

2. Go to Passcode & Fingerprints.

3. Fingerprints tab.

4. Click on the "Add a fingerprint" tab and then repeat steps 5-7 of the previous section.

IN latest model iPhone appeared new system authorization - fingerprint scanner Finger Touch ID. More precisely, a fingerprint sensor, because it is not an optical scanner, but a CMOP chip (Fig. 1).

WARNING

The technology for the production of such sensors was developed by AuthenTec, which Apple acquired in August 2012, along with related patents.

The sensor takes the key characteristics of the fingerprint (not the photo) and stores them locally on the phone. Apple swears that this private information is not sent to central servers.

Why is it needed

If access to the phone of a friend or girlfriend is required, then bypassing biometric protection is not difficult: it is enough to take his / her hand in a dream and attach it to the device. Problems arise if we have gained access to the phone, but the user is not available or is constantly conscious. In such situations, you have to use the method of making fake fingerprints.

By the way, hackers have long been making artificial fingerprints to deceive biometric protection. The first such systems appeared in the early nineties, and instantly there were options for making artificial copies. Tsutomu Matsumoto's 2002 manual is considered a classic.

The problem is that recently the quality of sensors has been growing, so the requirements for the quality of prints have also increased. But still, with sufficient diligence, everyone can make an imprint, even if not the first time.

How to do it

Firstly, you need to know exactly which finger the victim uses for authorization, otherwise the amount of work will increase by an order of magnitude (literally by an order of magnitude: we will make ten fingerprints instead of one).

Having determined the desired finger, you need to find a high-quality print. We immediately warn you: it is almost impossible to find a high-quality print on the smartphone itself. Here, all the prints are partial and/or smeared, which doesn't suit us.

A bottle, glass or doorknob is very good for taking fingerprints. Such a print is then easy to process and photograph.

The fingerprint should be developed with graphite powder so that it is clearly visible. If there is no powder, you can use a pair of cyanoacrylate, which is part of the superglue. You can put a couple of drops of superglue on the bottom of the bottle cap - and gently lean the cork against the surface around the print, without touching it, so that the cyanoacrylate vapors affect the print. The chemical will show contours no worse than graphite powder.

Then the print needs to be photographed in macro mode. Now every smartphone has a camera that will provide enough good quality photos.

Further digital image opens in Photoshop or other graphics editor. It is necessary to prepare a mask for the future form. The print should be processed: increase the contrast and sharpness - and transfer to black and white mode (Fig. 2).

There are several ways to make a convex mask and what substance to fill it with to obtain an artificial imprint. To do this, you can use gelatin, latex milk or even wood glue.

In general, any clear liquid substance that solidifies and takes on a stable shape.

The mask can be made directly on toner bumps from a laser printer, but a more reliable option is to use a photosensitive circuit board.

The print is printed on a transparent film on laser printer with a resolution of 1200 DPI. We put the printout on a photosensitive form - and etch the form for pouring.

The last stage: fill the form with gelatin and place it in the refrigerator to solidify (Fig. 4). The finished print can be "put on" on your own finger - and used for authentication.

Today we will talk about how to set up and use fingerprint on iPhone 5S. It is a technology for identifying the owner of the device and makes it easy to unlock the gadget.

Touch ID is the name of this feature. Using it on an iPhone 5 or 6 is easy, but you need to know the basics of how it works. The fingerprint method here replaces the legacy password system. And if the password is often forgotten or lost, the fingerprint is always unchanged. And it's very easy to put it on. The device reads the information in an instant, and just as quickly, on the machine, the lock is removed from the gadget.

With this technology, the user can authorize any purchase from the Apple Store. The sensor has flexible settings and recognizes information from any angle. And it doesn’t matter at all how the finger was attached - the procedure will be successful. "Apple" device in any case recognizes its "owner".

Before setting up a feature, the first step is to enable it.

To do this, you need to perform such actions as:

• Go to your device settings.
• Click on the "Touch ID and passwords" section.
• Think up and enter a password from numbers. Be sure to remember the set of numbers. In the future, you will need it if you want to change the prints or protect them from being changed.
• Make your own prints by selecting the appropriate item. Next, you will need to lightly touch the "Home" button, and the system will automatically scan the image. When everything is ready, you will hear a vibro signal.

If the scan was unsuccessful and a number of places were not processed, these areas will be highlighted in red on the display. It will be possible to make 5 more attempts to scan.

And keep in mind that the "Home" button before the procedure must be thoroughly cleaned of dirt and dust.

Setting up Touch ID

So, we discussed above how to install the function. And now we will learn how to set up a fingerprint.

It is assumed that the password has already been thought up and entered into the system (we did this earlier). After that, you need to follow this algorithm:

• Wash and dry your hands well. Also check the home button for cleanliness.
• Enter touch settings ID and password, where to enter the previously created combination of numbers, that is, your password.
• Click the Add Fingerprint button. Touch the "Home" button (while holding the gadget in your hand the way you do it most often).
• Touch the same button again without pressing. Remain in this position until vibration occurs or a specific prompt appears on the display.
• Several times to make a slow touch of the finger, then lowering, then raising it. Each time you need to change the position of the finger.
• A window will pop up, where there will be a proposal to adjust the capture. Here you need to hold the gadget the way you usually do it during the unlocking process. You need to lightly apply the pads of your finger to the Home button (but not the central segment, as was done at the beginning).

If the procedure did not take place for some reason, try to repeat it, but on the other finger.

Unlocking the gadget, and purchases using Touch ID

Finally, let's get down to the main thing, and find out how to put this into practice in practice. useful feature. After you have adjusted the sensor, you can use the technology to unlock your device. To do this, you just need to click on "Home" with the same finger that is registered with Touch ID.

How to use technology for shopping? It is also very simple, but you need to know some nuances. The sensor here is Apple's ID number identification password replacement.

So, you need to do the following steps:

• See if the Touch ID and password section is enabled in the settings, and in addition, the parameter regarding the stores on the network where purchases will be made. If you cannot activate these items, log in using standard method identification by ID.
• Go to the page of the store you need on the network.
• Click on the selected product. A window will pop up asking for your ID.
• In order for the desired product to be yours, it remains only to lightly touch the "Home".

How to use Touch ID with Apple Pay

On newer models of "apple" gadgets (for example, the sixth line), the sensor is used more widely. It is applicable for purchases in stores, in various software, on online resources in Safari browser using the service Apple Pay.

Another technology is used on iOS gadgets to make purchases online from devices running on the Mac operating system. This is where Apple Pay comes in handy. However, most often, users use the technology to unlock the gadget.

Ways to manage Touch ID settings

In the Touch ID menu settings, you can implement functions such as:

• Disabling or deactivating technology for passwords and various online stores.
• Taking fingerprints. If you make several prints at once, recognition will be slower.
• Name a different name for a previously created fingerprint. To do this, click on it.
• Remove an element with a swipe gesture.
• Identification in the list by touching the "Home" button.

This fingerprint in the list will be highlighted for a short time.

If your gadget runs on OS 10, click on the button mentioned earlier using Touch ID to unlock the device.

If you do not want to use this button, go to the main settings. Next, click on accessibility and select the item with the name of the button. It remains only to enable the option to open with a finger application.

Sometimes the user is required to enter a password or an Apple ID instead of using the Touch ID feature. This can happen for the following reasons:

• After a recent reboot of the gadget.
• If the system did not recognize the fingerprint 5 times in a row.
• If the gadget has been in a blocked state for more than 2 days.
• When the user recently registered fingerprints or erased them not so long ago.
• When the user wants to enter the Touch ID and password section.

If you are unable to use a function for any of the reasons above, try one of these methods (or each of them):

• Check that the operating system on your iOS gadget is the most recent version.
• Make sure the home button is perfectly clean and dry. Also check your hands for this item. If the button is dirty, gently wipe the element with a clean, lint-free cloth.
• The button must be fully closed with a finger. And this also applies to the rim around it. Scanning with the sensor is further complicated by touching or moving the finger too quickly.
• If you are using a display protection case or a special film, make sure that they do not cover the desired button and its frame.
• You should make sure that the iPhone unlock option is activated in the Touch ID and passcode section. You also need to check that the fingerprint registration has been made and saved in the system.
• If all else fails, try another fingerprint.

Well, if the last method did not solve the problem, contact the seller, an authorized repair shop or support service on the company's resource on the network.

At first glance, it seemed that the fingerprint scanner samsung fingers The Galaxy S5 is quite good, despite the fact that there is not much to compare with. What was especially pleasing was the ability to pay for your purchases using PayPal.

However, a recent hack showed that biometric scanner The GS5 has the same drawback as the iPhone 5S - it can be hacked.

Security Research Laboratory (SRLabs) recently uploaded to YouTube video, which was easily fooled by the Galaxy S5's fingerprint scanner. With a stolen print, you can make a fake, which the company also used to outwit iPhone system 5S TouchID.

However, both scanners have their own peculiarities of use. Before you can use the scanner to unlock your phone, Touch ID requires you to enter your passcode. Plus, every time you reboot your iPhone 5S, you have to enter the passcode too. The Galaxy S5 does not provide for such actions, even after rebooting the phone.

Worst of all, even after a reboot, PayPal doesn't require a password either. That is, if the app is set to automatically authenticate with fingerprints, it is very easy to access it.

Watch the SRLabs video with the Galaxy S5 hack and be surprised how simple it is.
