Why do all software now need permission of address book and photo album? Are there any hidden dangers?

Many friends, especially users of Android phones, must have found that many apps need permission to view your address book, photo album, SMS, location and so on. When it is used for the first time after installation. Why? Can we not allow it?

So why do these apps get these permissions? In fact, they require different permissions for different purposes.

Let's talk about accessing the address book first. The reason why the APP wants to visit your address book is to help you match your friends in the address book, so that you can quickly find people you know in the APP and the social links of your resume in the app. Second, the APP wants to explore potential users through your address book, thus prompting you to invite friends in the address book to download and register this software in the application.

Access to photo albums allows you to upload avatars, send pictures and videos, especially those social applications or short video applications. This permission must be turned on. The second is to recommend different advertisements or products to you according to the contents of your photo album.

The first purpose of accessing SMS is to read the verification code, so that you can read the verification code directly when logging in, which saves the trouble of input. The second is to collect information such as users' economic status, consumption preferences and activity areas. We can make detailed portraits of users to support product development and update, or accurately push marketing advertisements.

As for access location information, it is common in some LBS-based applications, such as take-away software, e-commerce software, social software and so on. This purpose is generally for the functional services of products, such as social software can help you find strangers around you, take-away software can easily determine the surrounding shops and so on. In addition, it is also to study users' portraits to support them to conduct accurate data analysis, thus improving products and enhancing competitiveness.

Many softwares also require the use of some other permissions. The main banner is to let users have a better experience, but the "hidden rules" behind it will not be said. And that's why many people choose Apple phones. Of course, in fact, whether you use Android or Apple, you can't avoid the leakage of all kinds of information.

Then these permissions required by these apps may bring various privacy leaks, so can we not allow apps to obtain them?

Because many friends will say that if you choose not to allow it, you may not be able to install it directly. In fact, personally, if it is commonly used software, such as WeChat, Taobao and Alipay, it can still be allowed. After all, these are just needed, and many functions cannot be realized without it.

Other applications that are not commonly used can't be used without permission. You can allow them first, and then turn off some permissions in the phone settings. Most mobile phones support this function, depending on individual needs.

In this era of big data, it is almost impossible to have any personal privacy in general. Unless you refuse to use electronic products, there will always be information leakage in one way or another. So you don't have to care too much about these problems.

But everyone must go to a regular app store to download apps, such as app stores of major mobile phones, app treasures and so on. The apps on these platforms are relatively safe or guaranteed.

Don't download applications from QQ group or some bad websites at will. Most of these applications have viruses or other security risks, which may even allow illegal hackers to directly infringe on important information in your mobile phone and even cause economic losses.

Although information leakage is inevitable, everyone still has to wake up the alarm.
