Have you ever had the experience that an advertisement will appear when you brush a circle of friends?

in the professional class, as soon as the teacher finished speaking, the students took out their mobile phones and brushed up their circle of friends.

A few students were randomly selected, some of them were dressed in fashion, some were dressed in YSL makeup, and some were dressed in wedding photography.

The teacher painted furniture and famous cars-she just bought a house not long ago.

have you noticed that these advertisements seem to be particularly targeted?

it seems to know the needs of people of all ages.

Just like Taobao, the shopping cart will "guess what you like" when it reaches the bottom.

does it look amazing?

It's like having a little assistant. It's sweet and easy. The key is to know you.

but going back to the essence through appearances, don't you think it's horrible?

There is a word called "Precision Marketing" in our professional class, which means:

On the basis of precise positioning, we will establish a personalized customer communication service system by means of modern information technology, and realize the measurable and low-cost expansion of enterprises in Zhang Zhilu.

is one of the core ideas in the attitude-oriented network marketing concept.

Look, how accurate the WeChat friends circle advertisement is!

why can it know you better than your mother? This is worth thinking about.

the advertising in wechat circle of friends is targeted.

just like the example above, it will recommend related products to people of the right age.

so the question is, how did you reveal your age? In fact, this is not difficult to think of.

nowadays, apps are generally authenticated by their real names when registering.

In other words, your name, gender, ID number, home address and other basic information have been completely handed over to the other party before using the APP.

Some netizens may think: What about my gender?

in the traditional sense, you can tell something from the name.

For example, when you are authenticated, you fill in the name of Chen Juhua, and then you tell Tencent that you are an out-and-out man. Do you think Tencent will believe you?

Are those people whose names are "neutral" safe?

not really. Have you ever taken a selfie in your circle of friends?

You can not only see the gender, but also guess the occupation and work place in the general direction.

Some small netizens are glad that they never send selfies in their circle of friends, so you always send selfies in your circle of friends, right?

Tencent can roughly determine your gender, hobbies and so on according to the scope of your daily concern.

A small number of people will stand up and say: I am better, and I send a circle of friends almost once a year.

The last one is to forward China Mobile's traffic package consultation, so you must have chatted with others.

Isn't it exposed when people call you "Iron Bull" or "Er Ya"?

Very few people will say: Sorry, I seldom chat on WeChat and never send friends.

congratulations, then. The information is relatively complete, because you are of little value to Tencent?

besides other apps, do you think it is safe?

have you noticed that there are always two ways in the login interface?

either enter an account to log in, or log in indirectly through a third party (QQ, WeChat, Weibo, etc.).

for the convenience of the map, people now often log in through a third party.

at the same time, your name, gender and other information have been completely handed over to the APP.

Through background analysis, it will recommend some things that you may be interested in according to your age, occupation and hobbies.

it's not how sweet the APP is, it's that you indirectly tell it that that's all you need.

it's just a porter.

the teacher said that not long ago, she brushed an advertisement: at the age of 3, you should be better to yourself-

-this is an advertisement for a luxury car.

Look, how powerful the advertisers in WeChat circle of friends are.

not only precise marketing is realized, but also emotional marketing is added, which allows you to take the initiative to consume unconsciously.

so, an APP can get to know you to this extent.

You can still think that you are the only one who knows about it, even if you close the curtain and turn off the light.

with so much privacy exposed, how can we feel safe?

use APP less?

try to use a pseudonym when registering?

the p>APP is independent, and it is not associated?

you have to live.

Now, it is absolutely impossible to realize the independence of the APP.

as long as you use wechat, your information is bound to be leaked.

Therefore, big data has become a double-edged sword:

It is not only a powerful tool to lead the times forward, but also a powerful backup for people with ulterior motives to steal information.

Uncle Ma Yun, who said "everything is right", once said:

"Many people haven't figured out what PC Internet is, and the mobile internet is coming. When we haven't figured out the mobile internet, the era of big data is coming again."

in other words, the arrival of the era of big data is the objective law and inevitable result of the development of the times. It is inevitable.

So what the era of big data brings will only make you worry about privacy exposure?

The earliest big data player was TARGET Department Store, the second largest supermarket in the United States.

In a precision marketing in 212, TARGET once surprised a father who was going to sue the company that his high school student daughter was really pregnant.

And this discovery was one month earlier than my father's discovery, which was reported by the new york Times and caused a sensation in the whole country.

how does p>TARGET do it?

In fact, TARGET's mind-reading is based on the results of data analysis and comparison and screening.

after analysis, the system made personalized recommendations to users.

That's why I know that I should give the little girl diapers and baby carriage coupons according to what she bought.

on a small scale, for us personally, the first thing is very basic and easy to do, which is to make friends carefully.

Don't leave your basic information on major platforms at will, and don't post your beautiful photos on various social platforms.

more people feel your makeup.

but how do you know that there is no one in the friends list who saves photos of your friends circle and then goes to other platforms to do some cross-cutting transactions?

at present, it is basically impossible to completely keep personal information.

after all, this is an age when you have no idea how you got into hot search.

Big data is a double-edged sword. Are you a hug? Or refuse?
