Why do all software now need permission to address book and photo album? Is there a security risk?

Many friends, especially users of Android phones, must have found this when using smart phones in their daily lives. Many applications need permission to view your address book, photo album, SMS, location and so on when they are used for the first time after installation. So why do these applications get these permissions? In fact, they ask different authorities for different purposes. First, let's talk about accessing the address book. The reason why the APP wants to visit your address book is to help you match friends in the address book and let you quickly find social links and resumes of people you know in the APP. First, the APP wants to explore potential users through your address book, which can prompt you to invite friends in the address book to download the registration software. Access to photo albums is for you to upload pictures, send pictures and videos, especially those social applications or short video applications. You must open this type of access.

The second is to recommend different advertisements or goods to you according to the contents of the album. The purpose of access 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 third is to collect information such as users' economic status, consumption preferences, and activity areas. , and describe users in detail to support product development and update, or to accurately place marketing advertisements. As for accessing location information, it is usually used in some location-based service applications, such as take-away software, e-commerce software, social software and so on. This purpose is generally for the functional services of products. For example, social software can help you find strangers around you, and take-away software can easily determine the surrounding shops.

In addition, it is also to study the portraits of users, so as to support them to carry out accurate data analysis, thereby enhancing products and competitiveness. Many softwares also require other permissions. The main banner is to let users have a better experience, but the "hidden rules" behind it will not be said. This is why many people choose Apple phones. Of course, whether using Android or Apple, all kinds of information are inevitable. Then these permissions required by these applications may bring various privacy leakage problems. Can we not allow applications to get them?

Because many friends will say that if you choose not to allow it, you may not be able to install it directly. 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 we don't have to care too much about these problems. However, when downloading applications, you must go to a regular app store, such as the app stores of major mobile phones, Yingyongbao and so on. Applications on these platforms are relatively secure.
