The so-called transparency means that users do not know. When the user opens or edits the specified file, the system will automatically encrypt the unencrypted file and decrypt the encrypted file. The file is ciphertext on the hard disk and plaintext on the memory. Once you leave the use environment, the application can't be opened because it can't get the automatic decryption service, thus protecting the file content.
Forced encryption: after installing the system, all files of specified types are forced to be encrypted;
Easy to use: it does not affect the original operating habits and does not need to limit the port;
There are no internal obstacles: internal communication can be communicated without any treatment;
External obstacles: once the file leaves the use environment, the file will automatically become invalid, thus protecting intellectual property rights.
Transparent encryption technology is a technology closely integrated with the driver layer kernel, which works at the bottom of the operating system. By monitoring the operation of the application program on the file, the ciphertext is automatically decrypted when the file is opened, and the plaintext in the memory is automatically encrypted and written into the storage medium when the file is written. So as to ensure that the files on the storage medium are always in an encrypted state.
