[Core hints] Recognizing distorted captcha is not the only way to identify humans, so how should designers change the captcha? What should be the design of a mobile device verification code that may be coming?

What is a CAPTCHA?

In the eyes of ordinary users of the verification code is absolutely an annoying thing, for the users of myopia is so, we do not know why we always have to go over and over the difficult to identify the graphics and letters. However, when we think carefully, we find that this complex verification code is one of the greatest inventions of mankind.

If you make a simple definition of a captcha, it is that the code is a tool that the computer uses to identify whether the operator is human. The validation code usually consists of a number of characters with irregular lines and sizes, the above problem or text can only be solved by human, the advantage is that the use of authentication code site can effectively prevent garbage users to use the machine repeatedly post or register, to avoid malicious crack passwords, brush tickets, forum irrigation and other phenomena occur.

"Inhumane" Verification code

We are more or less in the use of the Internet need to enter the verification code, we are gradually accustomed to enter those difficult to identify the text, but it is undeniable that the process of input verification code is indeed very painful. The voice of the users who wish to correct this phenomenon has always existed.

At present, the situation of input verification code in mobile devices is rare, but with the enhancement of network security awareness and the development of mobile Internet, the verification code is unavoidable in the mobile end, then the shortcoming of identification code recognition difficulty and low input accuracy will be directly exposed to the user. So can we replace the traditional captcha with a simpler and more efficient way? The answer is yes.

Click Not input

When registering for a forum, we must first visually identify the text displayed in the Verification Code box, and then enter it into the Submit box via the keyboard. If we enter a code that is wrong, we are likely to face the painful process of reenter the password and confirm the password, and then continue to identify the verification code, which is by no means a good user experience. And recently Baidu Bar to remove the Verification code input box, replaced by the selection box, this is an amazing design!

Use the mouse to choose the feeling is absolutely more comfortable than from the keyboard input, but also eliminates the switch input method and find key trouble. After we click to complete four characters, if the input is correct, the system closes the window and tells the input to be successful, if the input is incorrect, will continue to retain the window. This kind of design whether in rational or perceptual aspect will give the user a simple and convenient feeling, if the dopamine rewards mechanism comes into effect, the user may really fall in love with the authentication code.

Cars, not horses.

When horses are the main means of transportation people want only faster horses, but until you drive them in front of them, they will understand what they really want (see the 11586.html "> user motivation behind the product requirements)." In the development of traditional verification code, we found a lot of "horse".

1.Gif Animation Verification Code

This kind of verification code is usually more intuitive and simple, not too much difficulty in identifying. The main feature is that the verification code is a circular GIF animation, display static verification code time only A or, this animation code can effectively prevent the machine to recognize the content of the code, but also enhance security.

2. Advertising Verification Code

This kind of verification code is usually an advertisement picture, because the advertisement is appearing randomly, and the verification code can increase the revenue of the website when performing the check, so the use of this kind of verification code is also more common. In reducing the difficulty of recognition, many sites also have their own thinking, such as the answer to the question of the verification code is the name of the site, or the use of mathematical formula to verify the code, but these evolution of the verification code is not free from the drawbacks of input, you can say that the future of the Verification Code

Simple, not tedious.

The Associated Press Twitter account was stolen some time ago, and hackers posted false news of the White House bombing of the president's injuries via Twitter. The news comes as calls for a double verification of Twitter and Weibo appear on the web, and the main way to double authentication is to verify the code. We can see that the verification code will slowly appear in our mobile device, and the verification code will become easier to enter. So how does a captcha on a mobile device change?

1. Click to select

As mentioned above, the mobile phone keyboard itself is nine territory, we can enter the code like the phone to enter the CAPTCHA, this is not a very magical thing? We probably do not need to "click the input box → pull up the keyboard → input" This cumbersome process, a few clicks on the screen to fix things, why so complicated?

2. Handwriting

Handwriting is easier on the mobile side, and one of the main features of touch screen is handwriting. When we meet "1+1="? Verification code, we only need to draw a thumb on the screen with a not too standard 2 can be done, why not? At present, the system is not perfect for Chinese handwriting recognition rate, but the recognition of Arabic numerals is perfect, if you are interested can download handwriting calculator to experience.

3. Depict

When we were young we would draw graphs and imagine that if we just followed the instructions and drew a graphic to complete the input verification code, it would be great. The system can use simple geometry to replace the traditional verification code, through the dynamic arrows to let users know the order of strokes, the user only need to follow the painting on the touch screen OK.

All three of these methods give users a clear idea of the information that the verification code represents, and reduce the input burden, and in the era when the touch screen is about to dominate the computer, this type of input that really utilizes the touch-screen feature actually gives us a simpler operation experience, At the same time, we can use the mouse gesture to achieve the above operation in the non touch screen device, which is really surprising.

Conclusion

The key to double authentication is to protect the password, which prevents hackers from breaking user accounts only over the network, which is a necessary requirement for large web companies, particularly for Weibo, which supports many third-party Web sites. Perhaps in the near future we will register and login to micro-blog account also appear in the verification code, but please rest assured that it will be a simple and elegant way to appear in front of you, because the change has begun!
