How to protect mobile phone privacy and data? 3 ideas to fly with you!

The time and frequency that many small partners use mobile phones in this year has far exceeded that of notebooks and PCs, so the importance of data in mobile phones is far from being comparable to these oversized guys. The question is, how can we better protect the privacy and information in mobile phones? In fact, the vast majority of Android phones have already prepared for us a package, the key is whether you can find them and make reasonable use of it.

Insuring data

What is the most embarrassing thing in using a mobile phone? That's right, it's the hand erroneously deleting the photo, hand-shake unloading an app. So when it comes to data protection, the first thing we need to do is put aside insurance for "hand shakes."

Many of the latest Android phones have integrated Recycle Bin functionality. For example, the OPPO R11 will delete deleted pictures by default in the recycle bin, and they can be restored at any time if necessary.

OPPO R11 comes with a recycle bin mechanism, but only for photos

However, not all cell phone models provide similar functionality, and easily deleted by mistake is not limited to photos. Therefore, Xiao Bian suggested that you install "Dumpster" on your mobile phone (please search for the download address yourself), a powerful file recovery application.

After installing Dumpster, remember to add it to the lock screen to clean up the whitelist of memory and open the APP list to make sure it stays in the background. Because the recycle bin mechanism will fail after the APP is closed, only the background runtime can guarantee that the deleted data will enter Dumpster's save list.

While Dumpster is running, all photos, videos, music, documents, and uninstalled apps that you deleted will be saved in the software's backup space. Clicking on the deleted files will restore the original location.

Remember to use a strong password

Fingerprint recognition has long been popular on Android phones, and touch-screen type information screens have been used to unlock the best efficiency. However, many children's shoes still ignore the lock screen password setting before entering the fingerprint. If you are still using a 4-digit password, your phone will be in a very dangerous situation.

If the mobile phone is lost or stolen, the risk of four-digit password being masked is high, and once it is encrypted by a malicious cracked fingerprint, it is meaningless. Therefore, the correct lock screen password should be selected letters + numeric password or pattern password, the former will be extremely difficult to crack after adding case and characters, the pattern password can refer to the following figure, the use of pattern password can overlap line features, the more complex or more Surprisingly better.

At the same time, unless you need to temporarily, please check the phone's developer mode and USB debugging mode options must be closed, register mobile brand members and log in, open a similar "recover phone" function. If you turn on the USB debugging mode and do not turn off, once the phone loses access to the PC, you can use some software to crack the password!

In this way, even if the mobile phone is lost, there is no USB debugging mode. The other party cannot delete the password through the PC, but can also locate the mobile phone by retrieving the mobile phone function, or remotely delete all the data in the mobile phone. These are good habits that we need to cultivate.

The encryption experience is not the same

Almost all Android phone brands today integrate application encryption on the system, and some brands can also implement application icon hiding. Compared with application encryption, the hidden effect of the application is better. After all, pure application encryption, the icon is still on the desktop. If a friend “forces you to open,” privacy is just a joke .

In addition, the functions of a file safe (usually located in the file manager) are the main features of Android phones, and their operation procedures are basically the same, they all open the "file safe → add files", and then need to enter the file safe before each Password or fingerprint verification. However, there are significant differences in the encryption principles of different brands.

Taking the OPPO mobile phone as an example, the pictures and videos added to the safe list will be transferred to the hidden directory of the private system and cannot be read by the mobile phone APP. When connected to the computer, it cannot be found by the Windows system. However, as long as the file safe is verified, the video inside can be directly played and the picture can be browsed.

The "secret cabinet" with Huawei's mobile phone as its representative brand adopts another idea: entering the security cabinet not only requires verification, but also requires a similar decompression process each time the video or picture is read.

If OPPO's safe is a simple file hiding, and Huawei's security cabinet is hidden + encrypted , the advantage is that even if the encrypted file is found through the ROOT phone, the actual content can not be directly read without the key.

However, the shortcomings are also obvious. Every time you want to see the security cabinet file, you need to decompress it. If you have hundreds of megabytes of video, the waiting time may not be short, and once you exit halfway and then enter the safe, you need to unzip it. Take time.

In addition, if your Android phone supports multi-user login, we can protect the privacy content through the owner and the visitor.

When you use the owner mode, when you use it, you enter the guest mode (you can enter different users through different fingerprints). The data of the two modes is not shared. Is it more convenient?

Some brands will integrate functions such as “private space”. Take Jinli Mobile as an example. In the private space, our calls, SMS, recordings, photos, and added APPs will be encrypted and protected, enabling deeper personal privacy and security. protection. In short, when you buy a new Android phone, you might as well research whether the system provides the above-mentioned settings and functions related to data security, find and open them.
