The SDK is a "software development kit", a collection of development tools, which can be used for specific software packages Application software , software framework, hardware platform, operating system and other products.

Some applications exposed by CCTV to steal user privacy

Then, in the face of these problems, we must develop the following habits to effectively avoid information leakage.

02 How to effectively prevent?

Application permission management

When we think about APP privacy, we will think of "permissions". Yes, APP permissions are like a lock. But most people download After a new APP is launched, it is generally allowed.

You may say that most applications can't be used without clicking "Allow", but it's obviously wrong to click "Allow" all the way. The permission of the application should be selectively opened, and it is not allowed to be lazy to agree with all applications, especially those that are unfamiliar or involve money.

For example, it is unnecessary to turn on the microphone, camera and location information for some APPs, so it is unnecessary to click Allow. If you didn't agree with all of them before, it is recommended that you check them carefully, especially those "unknown" APPs. Open [Application Permission] to view them.

For example, you can select "Allow only during use" for location information, and prohibit microphone, phone, SMS, camera and other unnecessary items.

Download applications via official channels to avoid malware

Unlike in the past, mainstream mobile phone brands now have their own "software stores", which can only go home after the official security audit, so the security is guaranteed. We'd better choose official channels for downloading applications, and third-party platforms should also choose formal ones.

Mobile data cleaning

Many people will choose to recycle or resell their mobile phones after they have been used for a long time. At this time, personal privacy information stored in old mobile phones is very important. Although the formal third-party recycling agencies on the market will specifically clean up personal information, they are not afraid to do so in case of emergency. It is reassuring to clean up in advance.

The most effective method here is Storage Overrides 。 The old phone data is cleared, and then the factory settings are restored. Then download other videos, pictures and applications again until the phone's memory space is full. Here, continue the previous steps, clear and restore the factory settings, and repeat the operation several times.

Although it seems troublesome, the direction of storage coverage can effectively avoid the disclosure of personal information, and third-party recycling agencies generally use this method to help users clean up personal data.

Write at the end

It has to be said that the risk of privacy leakage in personal mobile phones is ubiquitous in daily life, which reminds us to form the habit of using mobile APP correctly. What's your best way to prevent cell phone privacy leakage? Welcome to leave a message to share~
