The various APP software we use now basically requires you to authorize and obtain various permissions on your phone the first time you open it. Generally speaking, even if there are three types: location information, access to contacts, and access to albums, why does the APP need to access your various permissions? Today, let's have a good chat with everyone:

In terms of simple positioning, this Big data can analyze whether you want to buy or rent a house. For example, if you need to change your residence every year, you may be a migrant worker renting a house.

Previously, List of Xiaomi products released a set of data about various apps obtaining the owner's rights, which is really shocking. The most exaggerated one is the location data, which means that every Xiaomi mobile phone will be located by various apps 3691 times every day, that is, it will be located once every 23 seconds on average.

The second highest ranking is the access permissions for the album, which is accessed an average of 2432 times a day. So we need to consider a question, why do these apps have to find ways to obtain all kinds of information about our location, album, and address book?

The answer is to use it for marketing, either to sell one's own products, or to sell data to companies in need, which is also used for selling goods. So, let me tell you not to underestimate this positioning information. Only this aspect of data can analyze your general situation.

Let me give you an example:

For example, the place where you repeatedly appear at 9:00 am and 6:00 pm is likely to be the place where you work. The place where you often appear at 9:00 pm and 7:00 am is probably your residence. This Big data can also analyze whether you buy or rent a house, and then according to the average price of your rental community, Big data can tell you whether your economic situation has improved or decreased in a cycle. If you haven't changed for several years, you are likely to be a local person. When judging consumption habits, this local person and migrant workers are two logics.

Alternatively, you can use your contact list to determine your interpersonal relationships, kindergarten or school to determine your parents' education level, and then provide you with accurate advertising delivery. So when we talk about this, you should understand why a software like a flashlight computer that doesn't even have advertising functions and gradually becomes clean is also trying to find your location information and understand your contact information, Although he didn't directly advertise to you, he can do data sales.
