Not all keyboards are the same. This is especially noticeable if you have a computer and asus laptop , acer, hp, dell, fujitsu siemens, toshiba, samsung, lenovo or whatever.

In computer, more precisely, USB keyboards on the right are digital block for the convenience of working with numbers and symbols.

In small laptops, there is no digital block on the right, but the function itself is. It is performed by the keys with letters, just to start using, it is necessary to enable this function.

These scanners are more susceptible to damage to skin fingers, dirt and grease. Modern sensors are able to "see" the subcutaneous layer, which exactly matches the surface properties. These sensors are not clogged with scratches on the skin or dirty fingers. Some sensors may damage electromagnetic radiation.

Finger scan sensors

A fingerprint is lit and photographed. Optical scanners can be contacting or contactless. Without touching the work, like ordinary cameras - photographing at a distance, but to ensure accuracy, they need additional finger holders. In other optical devices, the finger is placed on a special plate.

How to turn on the laptop in the right numeric keypad depends on the model, although in most cases the standard option is suitable.

Enable right numeric keypad

If you want to turn on the numeric keypad in your laptop on the right you need.

On most models, it is she who activates and deactivates this functionality. Most often, a combination with another is required - Fn.

Also, most laptops immediately turn on the indicator light, as if informing you that the device is turned on.

Optical print scanners are unpopular because they are unreliable. Thermal sensors create an imprint using the temperature difference between skin bumps and the remaining air in the grooves. As the temperature decreases rapidly, the finger must move through the sensor, and the scanner combines a series of narrow “stripes” into a solid image to transmit data to the print analyzer.

Subcutaneous Fingerprint Detectors

These sensors are often susceptible to electromagnetic discharges. Each element of the pressure sensor measures its pressure, and a printout image is generated from all the data received. Ultrasound - The finger on the base is scanned by ultrasound ultrasound. This technology has long been used in medicine and has no known negative effects. The human body transmits ultrasound in different ways: some tissues are transparent to it, some "reflect" it. Ultrasonic pulse echo for certain tissues is used to obtain an image of the image.

If this option does not work try using the Fn + F11 combination. Only this is not the only option.

Sometimes it may be necessary to press Fn + F10 or Fn + Fn12. Experimenting memorize what you are doing, or you may unwittingly enable or disable not what is required at all (pressing again will fix everything).

And what to do if the Fn button does not work, and it is used most often (however, most often it does not work).

Radiofrequency induction sensors using a radio pulse scan the subcutaneous finger layer. The company has already sold over 20 million fingerprint readers. Due to the large amount of work, it was decided to use various automated registration systems, which should reduce the likelihood of errors and significantly speed up the work.

Most consumers prefer shorter, easily memorized codes, so thieves are given additional opportunity only have patience in one. One of the "side effects" of biometrics can be increased aggression against property owners. For example, robbers cannot take a key from a person to get into an apartment with a biometric lock. Since the key is the man himself, there are only two possible ways : break the door or defeat the owner by coercion and attach his finger.

Then activate the fn button in it. Onscreen always displays real functionality.

Only when you first turn on the digital unit can be hidden. Then click the options and turn it on, then press the Num Lock key, it activates it on-screen and real.

In general, hundreds of models, so if you can not, without experiments can not do.

However, such events are few, since biometric locks are not popular. By the way, some systems verify that the person touching the finger is alive, and in this case such crimes are meaningless. Concerned about the fact that fraudsters who once stole biometric personal data could connect to banks, various websites, gain access to the premises and cause significant damage. This can be called almost perfect identity theft.

Fingerprints and other data of the same person are read differently each time, but after analyzing the collected data, the same result is obtained. If an ideal fake “key” is used, the biometric blocking system can detect too many overlaps with a template or previous measurements and not give permission to such “owner”. Reading a deeper layer of skin, making fingerprints even more difficult.

Sometimes you may even need a combination of FN and ALT (usually in Sony laptops). A good option to see in the instructions.

If you do not have it, you can always download the free electronic version on the manufacturer’s website. Successes.

The article describes how to unlock a laptop and a laptop keyboard.

Optical scanners broke out even with the use of duplicate copies of toy clay. Clarkson University professor Stephanie Skikers and his colleagues found that 90% of cases of plastic copies of prints were found to be genuine. When creating a special algorithm that takes into account the pattern of sweat, only 10% of errors occurred. Compared to modern technology, this is still a very bad result.

The use of optical fingerprint readers in the doors was inadequate and easy to mislead. The laptop's fingerprint reader was more robust to fraud, but it also gave up. Thus, we can conclude: thieves throwing a laptop can use the owner’s fingerprints left on his body, unlock biometric security, and scan all data.

Some users sometimes block and disable the keyboard on a laptop, which may be a problem for a beginner. The laptop keyboard can be blocked, for example, by accidentally pressing any key combination. Typically, this combination of Win and some other key (combinations may be different for individual notebook models).

Although most users' fingerprint readers are called password replacers, it is recommended that they be used as an additional tool. Fingerprint locks with fingerprint readers replaced the pre-existing mechanical locks. After some time, one prisoner proved that the leaders could enter any room. To do this, take any four digit code and place your finger on the scanner. The prison administration was forced to return to the previous mechanical locks.

For reasons of objectivity, it should be said that conventional mechanical locks with keys are also unreliable. Do not ask if you can unlock the lock. It is difficult to unlock an extremely durable lock, but still possible. One of the most bizarre ways to unlock mechanical locks has long been known - insert it into a special “shock key”. This tool can even be used by children.

In this review we will talk about how to remove / put a lock on a laptop keyboard.

How to remove the lock on the laptop keyboard?

If you suddenly blocked the built-in keyboard on a laptop, then explore several options for solving this problem:

• One of the most common mistakes that laptop users with shortened keyboards can make is pressing a combination of two keys: Fn and NumLock . This action turns on the digital panel, but turns off the set of other characters, in particular letters. You need to use this combination again so that the keyboard layout switches to the standard mode.
• If the keyboard on the laptop is really completely blocked, then depending on the model of your laptop, resort to any combination of keys (this combination should be indicated in the manual for your laptop): Win + ( F1 - F12 ), Fn + Pause , Fn + F7 , Fn + F12 .
• If you do not have instructions for your laptop, and you can’t find the key combinations you need to unlock, then go to the official website of the company that released your laptop. Download the instructions there, or contact technical support site, specifying the model of the laptop and the essence of the problem.
• When locking the touchpad (touchpad) on the laptop keyboard, press Fn and F7 simultaneously .
• If you use the Fn key in combination with others to unlock or lock, then it will be important for you to pay attention to the characters drawn on these keys. As a rule, these characters are entered in square brackets so that the user can immediately find them on the keyboard. But it is best to use the instructions for using your particular laptop model and keyboard, as the key assignment may be different for different laptops.

The identity of a person is publicly available and must be: therefore, we represent the world, the banking system, the network, websites. Then you need to confirm your identity with a secret key that our identity is correct. The latter are not very convenient, because they can be lost, stolen, they are not secret. Let's add biometrics to this. Who should use biometric devices in this case? Identify, grant permission, or both? The human body is unique, we can not change it as a password.

Moreover, our traces of identity remain everywhere, so the physiological properties are widely available. Thus, the answer is clear: fingerprints, eye irises and other human physiological characteristics are most suitable for identification, and additional measures are needed to access a particular system.

How to put a lock on a laptop keyboard?

As noted above, laptops come in different models, and today you can purchase mobile computer for every taste. Each laptop can have its advantages, but also has its own usage guide. For example, for each model a separate command is assigned to lock the keyboard.

Here are some examples of good biometrics. The supermarket uses palmar vein scanners to identify customers, but only the first and last name is stored in the database. The data is used to implement the loyalty program: customers collect points, receive special discounts. Since the purpose of the system is to allocate points only to a specific person, even stealing the entire database would be useless, and deceiving the reader and pretending to be another person would not cause much damage.

The library has a subscription system installed. A simple fingerprint reader is used, and important reader data is stored in the database: first names, surnames, birthdays, addresses, phone numbers, readings and books you want, etc. Readers do not need any additional cards or passwords. When identifying a person, the librarian displays his data and photo. If the person standing next to the table does not match the captured image, staff will immediately notice the fraud. In this case, the human factor is used.

To block the laptop keyboard, users also need to for various reasons : children click on the keys, a computer game requires the use of only the numeric keypad, the keyboard is not fixed and requires disabling. Consider several options for locking the keyboard on a laptop:

• The first is the easiest and quick way - use the key combination. You can enable laptop keyboard locking, for example, by simultaneously pressing Win and L. Put the lock on the panel with the letter set should be using the Fn and NumLock , as mentioned above. Another key combination is Fn and F6 / F11 , depending on the laptop model. In general, in in this case You can also advise to study the instructions for your laptop, so as not to have to act at random.

Since the books are published by library staff, they visually perform identity checks. The store has five sellers. The arriving staff at the checkout office recognizes the device as a person, and the sellers confirm their identity with passwords. When the seller enters the cash register, the dealer displays only one medium for him. By joining another vendor, this recognizable and instantly reloaded environment. If the cashier is not used for a longer period of time, sellers must confirm their identity again.

Biometric scanners would be perfectly helpful without thinking about choices and interests. particular person . For example, with a fingertip, a car is worn, mirrors are adjustable; start playing your favorite music; In general telephone numbers Frequently dialed phone numbers are displayed.

• The second way to ensure laptop keyboard lock is its normal physical shutdown. This, of course, will be a bit more complicated than in the first case, but any inexperienced user will be able to cope here. The keyboard is connected to the laptop with a loop. To disable this loop from motherboard , you need to gently open the laptop case.
• The third way to lock (and unlock) the laptop keyboard is to use third-party programs . The method, of course, is less convenient than the first of the above, but much simpler than the second. There may be a lot of programs for locking the laptop keyboard, but we will advise such as “ Toddler Keys ”. Download it at this link. Using the program is quite simple, below we give instructions.

Typical applications for biometric biometrics are usually described: systems that are sufficiently connected to one stage of identification. For example, if the banking system allows you to make payments simply by debiting your fingerprints, it will be unreliable. As a result, partially unreliable use of fingerprint readers for laptops, which allow them to connect to various sites without an additional password.

It may be better not to give up tingling, remember a few more passwords and make your data and virtual life safer. Regardless of the fact that you want to get rid of passwords, it is not recommended to do this for very serious purposes. However, fingerprint readers are now much better, so one level of identification and verification among ordinary users may be justified.

Download and install on your laptop " Toddler Keys " as regular program . There is no need to perform additional actions, the program is sharpened to work with any version of “ Windows ” both on laptops and personal computers . After installation, launch it, in the tray (right part of the taskbar) you will see the program icon. Right-click on this icon and then in the drop-down menu, click on the “ Lock Keyboard ”. That's all - the laptop keyboard will be turned off.

In the future there may be some biometric systems. For example, when approaching an ATM, he will try to identify human identity along the way and height. Later they scan the palm of a blood vessel, recognize the face, check the iris, and if the person says - know even the voice. If all of the above identification methods match, you can withdraw money without a card. Modern biometric systems work quickly, and in the future they will even improve, so the whole identification process will take only 1-2 seconds.
