Public Security: Do n’t let privacy “transfer” with your phone

Mobile phones have become a part of citizens' lives, and the frequency of mobile phone replacement is also increasing day by day, but the endless number of mobile phone leaks does make everyone very worried. There are many mobile phone functions, work data, private photos, memos, etc. will be stored in the mobile phone. In order to prevent data leakage when changing mobile phones, many citizens would prefer to leave the eliminated mobile phones at home.

Most mobile phones now have a cloud backup function (that is, services that provide free storage, backup access, etc. on the Internet). If citizens do not pay attention to turning off the cloud backup function and log off when transferring mobile phones, pictures or data backed up online will be easily affected. Download and use by people with bad intentions. "In addition, many software clients now have the function of remembering user information, especially some mobile banking clients. If they do not clean up and resell their phones, it is easy to cause losses."

In addition to leaking cloud backup functions, data recovery leaks are also relatively common. The actual content of the data deleted by the mobile phone is also stored in the memory card, and it can be easily recovered by just finding the correct method.

The police reminded that for the old mobile phones that were phased out for transfer, citizens must first process their data, not only to delete private data, but also to reset the system to avoid leaving clues. Secondly, it is best not to transfer the memory card together when transferring the phone. If it is a mobile phone with a built-in memory card, you can delete the data and rewrite the irrelevant data, and reuse the memory card space once, so it will be difficult to restore the data greatly increase.

In addition, the police also reminded everyone that there are some security risks when changing the mobile phone number. If the mobile phone number has been bound for financial services, the original binding will not be eliminated when the number is cancelled, and it is easy to be robbed by someone to swipe the bank card. Everyone should apply for the unlocking service in time to ensure the security of the account.
