How does the mobile phone know what you like?

Have you ever had such an experience? It's what we talked to others one moment ago, and we will receive relevant recommendations the next moment we take out our mobile phones. For example, what daily necessities do you want to buy when chatting with friends? Turning on your mobile phone the next day is a promotional advertisement for these daily necessities, and many discounts will be displayed. !

At this time, do you all have a doubt like me? Why does the mobile phone know what I want and what I like? Is it being watched? ! Is the smartphone smart enough?

Later, I checked some relevant information, saying that it may be that the software is playing tricks, and some software may have obtained our recording permission, and then uploaded it through background data analysis, and finally achieved accurate push.

The first thing to know is that social networking sites and shopping sites include the Apple and Android phones you use. The mobile phone itself has no right to eavesdrop on your phone or steal the search data of the mobile phone. It is mainly your behavior data that makes your mobile phone know what you want and like, so it will be pushed.

Mobile phones are also very smart. They won't make arbitrary judgments. For example, if you read an article labeled "Beauty" while playing with your mobile phone, it doesn't mean that you really like beauty, or your hands may be slippery. Therefore, mobile phones should judge your interest according to browsing time, search times, whether to forward comments, etc.

You often browse beauty, comment on beauty articles and watch beauty videos. The mobile phone will accumulate all your interest weights about beautiful women for a period of time, and then standardize them with S-shaped function, and finally get an interest tag value from 0 to 10. The higher the number, the more interested you are in the content containing beautiful women. This algorithm is not only limited to content interest, but also can build user portraits according to your consumption ability, consumption interest, social habits and other dimensions to calculate your preferences.

For another example, when registering an account, you need to enter trivial basic data such as name, mobile phone number, gender and location, which will eventually become thousands of fact labels and become a part of your behavior data.

The purpose of mobile phone tag collection is to create a portrait of the user, and finally simulate a "you" with your interests, hobbies and ideas from the messy tags.

Did you see this and break out in a cold sweat? Our own information has been collected, so who will protect our privacy? Don't worry, according to the Personal Information Security Standards Law, all labels of commercial advertising platforms should avoid accurate positioning of individuals.

Of course, if you are an iPhone user and don't want to see this behavior of collecting your behavior data and pushing advertisements to you, you can limit the collection of your behavior data by turning off the IDFA code in the settings.

Now is the era of big data. Our browsing habits and preferences on mobile phones are easily captured by big data, and then we can push corresponding advertisements to you. If you want to enhance personal privacy and reduce being captured by big data, you can make relevant settings, which can effectively prevent mobile phones from recommending relevant personalized content to us through monitoring.

Little friends who don't like this function can set the browser not to save data when browsing, or delete the corresponding data after exiting the browser, which can effectively prevent the recommendation of some advertisements. Although this operation may not prevent the promotion of big data advertisements, it can prevent most irrelevant advertisements, which is still useful.

Or you can turn off the related permissions in the following way, because many software will get the recording permission from you when you download and install it. If there is no ban, the backstage will secretly listen to what we say.

Open the settings of the mobile phone, find the application management, find the recording, turn off the recording or microphone function, or set it to be allowed only during use.

Then find the personalized push of the mobile phone: in the mobile phone settings, find the privacy, click in and there will be an advertisement and privacy, and turn on the restricted advertisement tracking function inside, so that the mobile phone will not push the corresponding advertisement according to the content you browse.

In fact, there are many secrets in the mobile phone that we don't know. The above mentioned is just the rain in Mao Mao. It's really scary to think about it. But anyway, I think many friends don't like being monitored like me, just set it up, it's as simple as that ~
