Why do I have to get all kinds of permissions no matter what software I log in to now?

Here you are. In China, a few people still use Apple phones, and most people still use Android phones. It is an eternal "truth" that Android phones are not allowed to be used. When we use a mobile phone application, we always get a pop-up prompt that the application needs some permissions. Most of the selected options are allowed, but are we really doing the right thing? 1. Address book permissions. Some applications need our address book for two main reasons. One is to find and explore your good friend relationship, and the other is to get the mobile phone number of your address book contact.

2. SMS permission. Generally speaking, applications that need to log in will require this permission, but will you receive SMS verification code of unknown origin? This may be caused by poor application, which can not only read the verification code, but also read the bank card balance, capital flow and other information.

3. Album permissions. Most applications get photo album permissions to facilitate users to upload avatars and store pictures, and photo software definitely needs photo album permissions. Some apps will secretly scan your photos to analyze your preferences and even your location.

In addition to the above three, we should also pay attention to the location and telephone authority. For example, if the flashlight application asks you for information such as address book and location, it will say that there may be a problem. Why do you have to read address books, photo albums and text messages no matter what software you log in to? Can you not give it? Generally speaking, in the era of big data, information leakage is normal unless you don't use electronic products. In public, people who want to get our information can use our information correctly.
