Recently, the "yanzhaomen" incident has become a hot topic for many people, and these indecent photos in the "yanzhaomen" are said to be leaked when Edison Chen handed over his laptop to a computer company for repair.

In the past few days, many readers have worried that some privacy information on their home computers has also been stolen. Yesterday, the readers worried that the reporter specially consulted some data recovery experts in Xi'an.

How does a networked computer defend against data theft?

Mr. Zhang said that most of today's home computers are connected to the Internet, so how can networked computers not be stolen.

In this regard, a software company's anti-virus engineer Li tiejun said that some hackers can learn about the work of the other party from the records opened by others; they can view everything about the other party from the documents, emails, and image folders. Even deleted files can be easily recovered.

Li tiejun said that he would use some professional "History trace cleanup software" every day to clean up the historical traces of the computer, so as not to leave a chance for hackers. For files that need to be deleted but involve privacy, it is best to use the "file shredder" to completely delete the selected files. It takes a long time for the computer to remain in the boot status, be sure to unplug the camera on the computer, or turn the camera to the wall, even if the computer is controlled by criminals, nor can they use cameras to capture users' privacy.

How can we "self-Destroy" data without asking people?

"How can I clean up my personal privacy information on my computer if I want to eliminate my computer ?" Reader Ms. he asked.

Du Yanchang, a professional computer data recovery company, said it is best to keep the hard disk for computers to be eliminated, regardless of whether there is any important data in the hard disk. If the hard disk is too small to be retained, it is best to erase the data in the hard disk. However, common operations such as repartitioning, formatting, and deletion cannot completely clear the data. By means of data recovery, data in the hard disk can be easily restored.

Method 1: delete the file first and then store it.

Before the computer is eliminated, delete the personal privacy file and then clear the recycle bin. Copy unnecessary files until the entire hard disk is fully occupied and cannot be copied again. In this way, the deleted files will be completely overwritten.

Method 2: low-level formatting.

If you have a certain degree of computer knowledge, you can try low-level formatting to completely delete the information in the computer, but this damages the hard disk.

Method 3: magnet adsorption hard disk.

If the computer cannot be turned on, and the personal information in the computer has not been deleted, the magnet can be used. For example, the magnet on the radio is sucked onto the hard disk. After a few minutes, the hard disk will be permanently decommissioned, the possibility of data recovery is almost zero.

Method 4: completely damage the components inside the hard disk.

There is also a more efficient way to clean up the data, that is, directly split the hard disk, thoroughly damage the disk similar to the disc in the hard disk to completely clean up the data in the hard disk.

Digital cameras only borrow machines without memory cards

In addition to computers, we also need to guard against leakage of privacy from mobile phones, digital cameras, and other digital products.

Du Yanchang said that many mobile phones now have memory cards. Users are advised not to use their mobile phones to take photos that involve important privacy or store important files. If you do not want to use the mobile phone memory card, it is best to use the magnet to wipe the memory card, the information will become invalid.

For digital cameras and digital cameras, it is best not to lend them to others. Even if you delete a photo from a digital camera or a digital camera, you can easily restore the photo with professional software. If you do not want to reject the photo and borrow a digital camera or camera, you 'd better just borrow a machine, do not borrow a memory card.
