How to prevent mobile phone information from being leaked?

1. It is not easy to crack the terminal operating system.

PS: We usually say "jailbreak" (IOS system), "ROOT”(Android system) and other operations to improve permissions. If the system is cracked, the update can't work normally, which is prone to system bugs and security loopholes, increasing the risk of encountering malicious programs and Trojan viruses. Once recruited, all the information in our mobile phone will be "shared" by others. If there is no special reason, don't crack the system, don't brush the machine.

2. Don't trust strange text messages.

Telecommunication fraud is rampant day by day, and the means are endless: disguised as "official tone", "loophole escalation", "lucky winning" and "bank card problem" and so on. When you receive SMS, email or news of unknown origin, remember not to be greedy and cheap, not to be deceived by attractive content, and not to click on links easily to avoid being "fished".

3. Is it safe to put data in the "cloud"?

Many times, in order to make room for mobile phones and facilitate their use, we will choose to upload data to the cloud. Even turn on automatic synchronization. However, in terms of preventing information leakage, don't turn on automatic synchronization, choose manual, encrypt and upload private information to the cloud. Information storage is mainly based on hard disk and USB flash drive.

4. Be careful with funds.

Mobile online shopping has become an indispensable part of our daily life. We should pay attention to the safety of online banking operation and have the awareness of controlling risks. Don't involve too much in binding bank cards. It's best to open a new card, and don't put too much money in the card to minimize possible losses. At the same time, paying attention to the real-time update of the mobile phone system can plug the loopholes in time and avoid being infringed by malicious applications.

5. Use public Wi-Fi with caution.

Although Wi-Fi has become a standard in public places, remember not to connect easily without any encryption or free Wi-Fi. Because such a network can easily expose your equipment to an unsafe network environment, your mobile phone may also be attacked and implanted with Trojans. At the same time, don't use software such as "Wi-Fi Master Key" and "Free Wi-Fi". The security of these softwares is debatable. Your Wi-Fi password may be shared by others and there is no security at all. It is best to put an end to such Wi-Fi. If you want to connect, avoid using your mobile phone to do things involving privacy.

6. Be careful when handling used mobile phones.

Used mobile phones and memory cards usually store previous address books, short messages, call records and graphic materials. Even if it is deleted, it can be easily restored by software. Therefore, used mobile phones need to be handled carefully, and the data in the mobile phones need to be cleared, and then the factory settings need to be restored.

In fact, Bao Xiao has a better suggestion: send the old mobile phone to Bao Xiao. There are professional information crushing methods here, which can make the data be overwritten repeatedly and avoid the possibility of privacy leakage. In this way, even after the data is restored, the privacy of users will not be threatened.
