How to set up a fingerprint scanner to log into Windows?

Windows 10 offers to eliminate the need to enter a password when logging into your computer.
Biometric authentication offers several methods:
- according to facial parameters,
- along the iris of the eye,
- by fingerprint.
In parallel, Microsoft is promoting its version of a universal authentication service: “Passport”.

By logging into it only once, the user can then log in without additional effort to those applications and websites that support it.
In the absence of biometric sensors on the computer, you will still be prompted to enter a password.
We'll look at fingerprint authentication.

For this purpose in Windows 10 there is Windows system Hello.

First you need to set up Windows Hello:
1. Click the “Start” button (with the Windows logo icon).
2. Next, select the items: “Settings” - “Accounts” - “Login Options”.

1. If a password for logging into your account has not been set, then you must set: “Password” - “Add”.
2. Next “PIN code” - “Add” - enter the code you created twice - “Ok”.
It is necessary since the mechanism is implemented based on the “Passport” service.

Protection activated.

Now in “Accounts” - “Login Options” - select “Windows Hello”.

Will open Windows window Hello with a greeting and an invitation to personalize your device, making it unique and more secure with a fingerprint rather than a password.

Enter the previously specified PIN code and press “Enter”.

Now you need to scan your fingerprints.
In “Accounts” - “Login Options” - select “Fingerprint”.

You will be prompted to perform a scan.
You need to place your finger on the scanner.

For each finger, you need to do this operation eight times so that the results are as reliable as possible.
This is necessary in case one of the prints is damaged as a result of a cut or other actions.
Click “Close” to complete the Hello setup.

Setting up account login Windows entry 10 completed.
Now after setup, you can log in by quickly swiping your finger across the computer's fingerprint scanner.

In case scanning does not work, you can always use your account password to log in.
We would also like to draw your attention to the fact that settings options in Windows may change over time.

If your computer does not have a fingerprint scanning device (dactyloscope), you can purchase a compact USB scanner PC fingerprint readers, such as BIO-Key International's Bio-Key: SideSwipe Mini Fingerprint Reader, SideTouch Fingerprint Reader and EcoID Fingerprint Reader.

They connect to USB port and are miniature platforms with a fingerprint scanner.
The only difference can be in the scanning technique: drag your finger across the pad or simply touch.

Twin BiCS FLASH - new technology three dimensional flash memory

December 11, 2019 at the International Meeting on electronic devices(IEDM) IEEE TOKYO-Kioxia Corporation announced three-dimensional flash memory technology - Twin BiCS FLASH.

The system protects against the entry of unwanted persons at the entrance to the organization and individual premises. A biometric reader can be installed in addition to an already installed intercom so that the organization’s employees do not distract the secretary by opening the door.

The advantages of the biometric identification method at the entrance are:

• 100% protection against ID forgery and unauthorized entry
• no expenses for purchasing cards, which can be significant for a large organization
• unlike a card, which is lost and forgotten, a fingerprint is always with the employee
• increasing the company's status in the eyes of visitors

System Description

The development of biometric identification technologies has made it possible in recent years to significantly reduce the cost of such devices. The solution is based on an autonomous biometric reader with an electric lock control function. The modern design of the reader fits harmoniously into any interior. IP65 protection protects against dust and moisture. The device can be washed with a wet cloth.

A nice bonus to the proposed fingerprint reader is the built-in card reader. It is possible to use contactless cards as an alternative identification option, as well as in addition to a fingerprint - to enhance security. In this case, to pass you need to put your finger and present the access card.

An electromagnetic lock is proposed as a locking device. It is reliable and inexpensive, but is only suitable for doors that open towards themselves. Exiting the room is done by pressing the exit button.

System operation

Employees' fingerprints are read by the device and entered into the offline memory of the biometric reader. Each user can be assigned up to 10 fingers, in which case they can use any finger to access the room. The biometric controller has an Ethernet port for connecting to local network. Programming of the reader is carried out either locally using a master card, or remotely via a LAN.

To enter, the user places his finger on the reader, then an instant search is carried out in the database and, if he has access rights, the door opens.

To exit the room you must use the button.

Attention! There is a prejudice against biometric identification that it is a repository of certain personal data of employees. This is wrong! The reader does not store an image of the fingerprint, but only a mathematical vector model of reference points. Those. It is not possible to restore the papillary pattern from this code in the reader’s memory.

Modifications and additional features

It is possible to install an additional reader at the exit to eliminate the possibility of an employee leaving the premises without a card.

Installation of a video intercom for identification and access to the premises of visitors.

Complete the power supply battery for uninterrupted operation of the system during a power outage.

Economic effect

Biometric identification will 100% protect you from unauthorized entry by intruders and reduce the risk of theft of employee belongings and material assets of the enterprise. In addition to this, biometric technology allows saving on identifiers (for example, access cards).

Serious financial institutions take a responsible approach to the security of online transactions. The software of reliable banks must include protection blocks against unauthorized transactions. As one of the measures to help protect the client, specialists of the Security Service of the Russian Federation have developed the ability to log into Sberbank Online using the client’s fingerprint.

How it works

The client can choose an identification method when logging into the online banking application using a five-digit code or a fingerprint, which is highly unique for each person.

Important! Previously, it was believed that each capillary pattern was strictly unique; according to modern data, prints are repeated in approximately one person out of a hundred thousand.

When selecting fingerprint input, the process becomes simple: just place your finger on the screen.

The function does not work on all gadgets. Certain requirements must be met:

• Android version no lower than 6.0;
• Fingerprint function support;
• for iPhone iOS versions from 9.3;
• For Apple devices Watch OS watch os 2.0 and higher.

The fingerprint must be added to the phone's OS as a means of unlocking the screen.

How to activate the protective function

The first step to adding your fingerprint to " " is to log into your account using the five-digit security code generated during registration. Next you need to do the following:

• go to the settings section;
• activate the menu item “Login using Fingerprint”.

Now the service is turned on, when you try to log in, the PIN code dialing panel opens, in the lower left corner the program will place a fingerprint symbol. Then you can enter the application without using a digital combination.

Poll: are you satisfied with the quality of services provided by Sberbank in general?

YesNo

Possible problems and solutions

Sometimes users have problems logging into the capillary pattern program. In 90% of cases the situation can be corrected on your own.

Important! When logging into the application several times in a row using security code the function is deactivated, and the user notices that the fingerprint in Sberbank Online has disappeared. In this case, you should carry out the activation procedure again, as described above.

Other reasons causing capillary print identification to not work may be:

1. Failure or conflict software. To fix the error, you first need to install everything Latest updates. If this doesn't help, try reinstalling your online banking application. You need to install the latest version.
2. Dirty sensor. The method of elimination is to clean the sensor from dirt.
3. Damaged or dirty capillary pattern on the finger. If after cleaning your finger from dirt the problem does not go away, you can try replacing the fingerprint in the phone settings.
4. Damage to the hardware. In this case, the only solution is to visit a workshop for repairs.

The method of identifying a client by capillary pattern is reliable protection from unauthorized access to financial management. It should be remembered that the use of a fingerprint is possible under certain conditions, failure to comply with which makes it difficult to determine the client’s identity.

FinTech - financial services provided through modern technologies. These include online banking, mobile payments and transfers, electronic wallets, contactless payments, investment management, financial accounting, etc.

What does the coming day have in store for us?

There are many directions in FinTech and there is room to expand. However, most solutions in the field are united by common trends. Such as the transition to performing financial transactions without the client’s personal presence, increasing the share of transactions by mobile devices, contactless payments, automation of financial services, virtual banking, use of “artificial intelligence”.

Trends in FinTech are close to global trends in software development, but adjusted for the conservatism of the financial industry.

Start over

Logging into the application is the user's first impression of the product and service. This module is often underestimated. What can we, as designers, do to make the first experience comfortable and functional?

Speed ​​matters

The frequency of logging into financial applications is high (several times a day). Security reasons require that the user log in again each time. Therefore, the process should be as simple and fast as possible. Good, modern technologies there is something to contrast with the traditional tedious authorization using a password and login. Here are the main login methods you can use to improve your user experience, in order of increasing speed and convenience:

Standard login using login and password

The most common and slowest method of logging into the application. Each time the user logs in, the user must enter a login and password. In addition to requiring user effort and time, this method also increases the likelihood of input errors. But even in such a situation, you can make life easier for the user. The “cunning need for invention” option is to save the user login. The next time you launch the application, the login will be automatically entered into the required field. Yes, you will have to enter a password, but even this will cut the login time in half.

One-time passwords and SMS parsing

A more humane method of logging into the application. Instead of entering a long and complex password, the user is authorized by entering a short digital password received via SMS. Yes, you will have to enter your login, but four numbers instead of a password are much faster and easier. This method becomes even better if you automatically take (parse) the password from the incoming message and insert it into the input field.

Fingerprint scanning

The fastest and convenient way login to the application. Thanks to Fingerprint technologies for Android and TouchID for Apple, login time is reduced from one minute to several seconds.

Not all devices are equipped with a fingerprint scanner, but their number on the market is constantly growing. Thus, according to reports from manufacturers of fingerprint sensors, market penetration of devices equipped with this technology was 20% in 2015, 40% in 2016 and is expected to exceed 50% in 2017.

In terms of platforms, the trend looks even more impressive. Share iPhone models with a fingerprint scanner on the market in 2016 - more than 80%. So, you can dare.

Designing a fingerprint login

Let's look at the design and implementation of logging into an application using a fingerprint scanner.

Fingerprints are stored in operating system device (whether iOS or Android), and not in the application itself. The application accesses system functionality to check whether the fingerprint matches what the user has added to the system settings.

It is necessary to think through all the scenarios that may arise when using a fingerprint.

Let's go through them. 0 or 1?

First of all, you need to check whether the user's device is equipped with a fingerprint scanner. If the answer is no, you should hide all buttons, icons and controls that are associated with the mentioned functionality. Essentially, there are two interface options:

As you can see in the picture on the right, if there is a scanner, a button with a “fingerprint” icon appears in the interface. The button is not active yet, because to create a special cryptographic key, the user must enter his username and password when logging in for the first time. However, the button was not hidden, but was used to call up instructions when pressed. And the instructions may be different, depending on whether the user has added fingerprints to the system or not.

Actually, the entrance itself is by fingerprint

So, the user logged into the application for the first time using a login and password. What will happen the next time you log into the application? To minimize the necessary actions, you can activate fingerprint scanning immediately upon opening the application. To log in, the user just needs to click on the application icon and, while it opens, place their finger on the scanner.

We leave the option to refuse quick login and log in traditionally or with a different account. That's all the magic: fast, simple, convenient.

Not by one entrance

We sorted out logging into the application. But how can you make the application login screen useful for the user even before authorization?

Please review the application carefully. Surely it contains regularly used services or information that can be shown to the user on the login screen. The ability to find the nearest ATM on a map, check exchange rates, or read important news without authorization makes the application useful even for an unauthorized user. And activity in the application itself is growing.

Instead of an epilogue

There are many more ways to improve a user's first experience that are not covered in this article. But I hope I have been able to provide food for thought on this topic and provide some direction for research.
