Why do you want to see your address book, photo album, SMS and so on no matter what APP you have now?

With the popularity of smart phones, downloading applications has become one of people's daily behaviors. But I believe that when you download the app, you will inevitably be asked to authorize the app to read your address book and store information (including but not limited to photos, text messages, videos, etc.). ), machine identification code, microphone, location information, etc. (According to the needs of each app, different apps require different permissions). If you don't agree, then you can't use this APP normally, which means it is a must. As long as you want to download this APP, why are these apps like this? Everything, in a word, is to obtain users' personal privacy information.

Of all the information I read, I think it is reasonable to read only the machine identification code and location information, and the rest are hooligans; Why is it reasonable to read the machine identification code? It's actually quite simple. Each machine has its own unique identification code. Reading the identification code can avoid your economic loss. For example, for a long time, bank accounts have been logged in on a mobile phone. Once you log in with another mobile phone, the identification code is different. At this time, in the logic of the bank APP, it will think that your bank account information may be stolen and will ask for further information verification. You can only log in after verification, so reading the identification code can be regarded as a protective measure for users. In addition, location information can also be considered reasonable for apps involving financial security and navigation. For example, a bank app, logging in to place A for a long time, frequently changing the other party's address in a short time, may be fraud and navigation. Needless to say, the distribution of the US group is hungry, which is understandable, but the location information of other apps is unnecessary, so I think these two permissions can be released for some apps.

In addition to the above two types of information, the rest of the stored information, address book, audio microphone, etc. It's really unnecessary. The main purpose of reading the above information by each APP is to read user information, spy on user portraits and promote them.

After authorized to read the address book, you will find that every time you use an APP, you will be prompted that so-and-so friends are also using this APP, etc. The purpose is to bring you closer to each other and increase your stickiness to this APP.

Not to mention reading the stored information, you search for something on Baidu, such as searching for electrical appliances, and immediately all the advertising places in each app will push you to shop for various electrical appliances; Or there are several photos of the same type in your photos, such as baby photos, and you can recommend milk powder and diapers. Or if you chat with others on WeChat to buy a house, all kinds of decoration materials and accessories will be pushed to you immediately; Even now, you don't need to enter. After the audio microphone is authorized, as long as you chat with others, the mobile phone is around, and when you talk about a product, you will use the mobile phone to push the corresponding product for a period of time. It can be said that information leaks everywhere.

If the above reading is to promote products, it is understandable, but reading short messages is extremely excessive. Does anyone still chat by SMS now? Not at all. At present, in addition to spam messages, SMS messages are basically bank transfers and large consumption that require SMS verification code or personal account change information. If you look at the personal account change information, the best you can do is to know whether you are short of money at present and whether to recommend various online loans to you. If you read the SMS verification code, the consequences are really unpredictable, so it is unknown and unclear. Don't download the authorized APP at will.

In this era of big data, we are basically streaking. Maybe you think it's private. For example, we hide our private photos or videos in our mobile phones. In fact, in the eyes of various apps, it is transparent. Since you can't change it, you can only be as careful as possible. It is best to download an app with high popularity in the application market. Various sources are unknown. The app developed by small enterprises should be installed as little as possible, otherwise we don't know when the funds will be lost.
