The biggest scam in Internet history: verification code

Verification Code Everyone is familiar with this device. You need a verification code to register, to visit frequently, and even to buy something. In addition, some verification codes make ghosts cry when they see them. It is a basic operation to fill in numbers by sliding right. There are not a few people who can't see clearly. They even have to do a variety of questions. Simply, they don't treat people as people. It is estimated that some verification codes can only block the access of real people. As for blocking the machine, it can only laugh without saying anything.

The word verification code was first used in 2002 by Louis Von An of Carnegie Mellon University Manuel Blum, Nicholas J. Hopper, and John Langford of IBM.

verification The original function of the code is to verify whether we are human beings and prevent too many machine accesses or machine codes from occupying the normal welfare. Prevent malicious password cracking, ticket swiping, forum watering, page swiping and other unconventional behaviors.

But in fact, most of these behaviors occurred in the early days of the Internet. Now various mature products have various prevention methods, so why do verification codes still exist?

Verification code is a low-cost and high-yield scheme, which can prevent malicious attacks on machines and scripts, because it only needs to verify whether you are a real person, and if not, it will directly refuse.

For example, these two types of verification codes are commonly used when filling in numbers and letters or sliding to a specified position.

There is also a slightly more complicated way to select patterns from multiple pictures that are the same as the answers to the questions.

On the surface, it can stop robots, but in fact? That's what I want to say.

If you have been connected to the Internet for a long time, you should have heard about the revenue of verification codes. In about 12 years, several domestic companies are expanding related businesses. The unit price entered for 1000 times is about 12 yuan. At that time, many websites had access to relevant businesses. But these entrepreneurial projects have failed over time. Now there are only some overseas online profit projects, and the rate is probably deceptive.

Of course, these are not the verification code scams we are talking about. But in the current technology has been very developed, and there is a limit to the number of real name accounts for each person, why does it still exist? There are two main reasons for this, but no matter which one, users are actually regarded as free workers.

At the beginning of the 21st century information age, a large number of paper materials and books need to be digitized. Manual input is certainly impossible, but it is easy for machine scanning to fail. At this time, manual input is required, and the correct answer is obtained through cross comparison of big data.

The working principle is not complicated. Some of the verification codes seen by the user are text that is normally used for verification, while the other part is text that cannot be recognized by the machine. If the user inputs the correct part for verification, the machine will assume that the other part is also correctly recognized. Combined with the cross verification of multiple users, the machine will successfully recognize the unrecognized characters.

So every time we enter a verification code, it is possible to make contributions to human civilization.

At present, there are many kinds of artificial intelligence, but all kinds of data must be fed to develop normally. Then entering the verification code can also help AI grow rapidly. The above probability that you can distinguish objects, traffic lights, sidewalks and so on are all jobs that help intelligent driving.

Don't believe in the online money making project. At present, such online earning projects are basically in India, where labor costs are very low. Basically, only 12 hours a day can earn about 30 yuan. Therefore, easy money making does not exist. Moreover, this act is illegal.
