In life, we inevitably have some privacy photos, documents and the like that we don't want to be known by others. Our usual practice is to hide or encrypt these photo files in a hidden folder on your computer. But even then we can't help but worry that these photo files are discovered by others. The reason for this psychological reason is mainly due to our uncertainty about the reliability of the encryption method that comes with this computer. In order to better understand the effect of the encryption method, we will briefly introduce the encryption based on windows. Microsoft introduced the Encrypting File System (EFS) in the Windows version to provide users with file encryption in the NTFS disk format partition. Many people will use EFS encryption for files that involve their work and privacy, preventing others from snooping. The encrypted file system provides a certain degree of protection for personal privacy, and it also brings trouble to users. When the computer user's password is lost, the operating system is crashed, and the disk media is damaged, these encrypted files cannot be opened normally. The Windows-specific EFS encryption file system can encrypt data to a certain extent and prevent unauthorized users from accessing data. However, there are loopholes that can be easily opened by some brute force software. The current security level of encryption is a way to make a combination of 0 and 1 meaningless by changing the underlying data arrangement of the original file. For example, just like a banknote put into a safe, it can only be relatively safe. If you encounter a forced lock, or if you try your luck with a good password, the banknotes placed in the safe can be easily stolen. But if we turn money into waste paper, is it safer? Of course, this so-called "waste paper" is relative to others. For you, you can change it back to money in some way. Is this a relative increase in security? Of course, it is impossible to turn banknotes into waste paper and then change them back to banknotes, but for document information, it is feasible. This way we have encrypted the photo. The use of this type of encryption software (such as: Efficiency Source Data Security Center - Baidu search download) can better encrypt private photos.
