Three tips for protecting hard drive data privacy

Many softwares now have a history function to help users remember the recently opened project and the user's preferences. Although this feature is convenient for users, it also allows the person to get the user's private information, especially It is very easy for hackers to steal your documents. To solve this problem is to encrypt the file, let me tell you some small methods that are easy to operate:

The first method is still useful for general users.

Use the Group Policy tool to set the hard disk partition where private data is stored to be inaccessible. Specific method: First select "Run" in the start menu, enter gpedit.msc, press Enter to open the Group Policy Configuration window. Select "User Configuration"->"Administrative Templates"->Windows Components->"Windows Explorer", double click on the right "Prevent from "My Computer" Access Drive " ;, select "Enabled", then select the drive you wish to limit in the "Select one of the following combinations" drop-down combo box, click OK. After confirming that you double-click to try to open the restricted drive, an error dialog will appear, prompting "This operation was cancelled due to the limitations of this computer. Please contact your system administrator ". This will prevent most hacking programs and viruses from invading your privacy.

The second method is just an encryption method that can only prevent gentlemen and cannot prevent villains.

Because a computer expert is likely to know this technique, the virus is not to mention, virus writers certainly know this trick.

Modify the settings in the registry to set a drive to be hidden. The hidden drive method is as follows: Create a new DWORD value in the HKEY_CURRENT_USER\\Software\\Microsoft\\Windows\\CurrentVersion\\Policies\\Explorer of the registry, name it NoDrives, and assign it the corresponding value. For example, if you want to hide the drive C, you will assign a decimal 4 (note that you must set it to decimal 4 in the assignment dialog). If our new NoDrives want to hide the three drives A, B, and C, then just add the DWORD values ​​corresponding to the A, B, and C drives. Similarly, if we need to hide the D, F, G three drives, then NoDrives should be assigned 8+32+64=104. How should I understand how to hide the corresponding drive. Most of the features of disk hiding software are currently implemented using this little trick. After hiding, WIndows can't see the drive below, so you don't have to worry about others peeking at your privacy.

The third is a little-known secret, using the "disk management" component that comes with Windows can also hide the hard disk!

The operation steps are as follows: right click " Computer "->"Manage", open "Computer Management" Configuration window. Select "storage"->"disk management", select the drive you wish to hide, right-click and select "change drive name and path", then select "delete" in the dialog that appears .

Most users don't dare to choose "delete" here, afraid to lose the data, in fact, there is no need to worry about fear here, it is impossible to delete a disk without data first! Because the system is tight Just delete the path so you can't find it! You want to restore it directly by repeating the above steps.

The first three encryption methods are implemented using the functions provided by Windows itself. The encryption strength is low and not suitable for business. Level needs. Here are a few more secure encryption methods.

The fourth is to use software to encrypt, many can be found online. And this encryption method is absolutely safe. Moreover, the encryption method differs from manufacturer to manufacturer. The principle of encryption is different.

Using WinRAR, you can securely encrypt your data. Whenever you mention WinRAR, you will always think of its powerful compression function. In fact, WinRAR's encryption function is also very powerful. WinRAR uses one-way encryption, and one-way encryption is impossible to crack.

Encryption using commercial-grade encryption software. Software encrypted on the Internet can be easily accessed by Baidu. For example, Enigma Protector is a powerful tool designed to add high-strength protection to your application.

There are also PGP and Nuclear Shield Data Guard. PGP uses virtual disk technology, which is characterized by emulating a hard disk drive with a large file and encrypting and decrypting the data stream during the reading and writing process. The nuclear shield data guard directly encrypts the physical sector of the hard disk, and can write the world's first powerful functions such as protecting the hard disk partition, encrypting the hidden hard disk partition, and locking the USB and optical drive. The technical principles of the two softwares are different, but the security and encryption and decryption speeds are reassuring and suitable for both personal and enterprise users. There are also some encryptions that require payment for encryption. The degree of encryption should be absolutely assured.
