How to protect the privacy data on the hard disk? (1)

Is there any way to protect the privacy information on the hard disk? The following is a method introduction:

The first method: use the group policy tool to set the hard disk partition for storing private data to be inaccessible

This method is for general users, this encryption is still useful. 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 "Prevent access to the drive from My Computer" on the right, select "Enabled", then Select the drive you wish to limit in the drop-down combo box of "Choose one of the following combinations" and click OK. After confirming that you double-click to try to open the restricted drive, an error dialog will appear stating "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.

Second method: modify the settings in the registry, set a drive to hide

This method is only an encryption method that can only prevent gentlemen, can not prevent villains. Because a computer expert is likely to know this technique, not to mention the virus, virus writers certainly know this technique. 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 drives, then NoDrives should be assigned 8+32+64=104. How about, you should 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 method: use the "disk management" component that comes with Windows

The operation steps are as follows: Right click "My Computer" -> "Manage", open the "Computer Management" configuration window. Select "Save" -> "Disk Management", select the drive you wish to hide, right click and select "Change drive name and path", then select "Delete" in the dialog box that appears.

Most users are afraid to choose "delete" here, afraid to lose the data, in fact, there is no need to worry about fear here, it is impossible to try to delete a disk of your beauty 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 method: using software for encryption

A lot can be found online. And this encryption method is absolutely safe. And this encryption method is different from the manufacturer's different encryption principle. The following is a brief introduction. Several WinRAR can safely 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 that is encrypted online can be easily accessed by Baidu, such as Enigma Protector, a powerful tool specifically designed to add high-intensity protection to your applications.

There are also PGP and Nuclear Shield Data Guard PGP using virtual disk technology, which is characterized by emulating a hard disk drive with a large file and encrypting and decrypting the data stream during reading and writing. 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

which is reassuring and suitable for both personal and enterprise users.

The above four methods are for reference only, and I hope to help protect the privacy content in the hard disk.
