Embodiment Construction

[0020] The composition and structure of the software and hardware system of the file transparent encryption method that adds the file tail is as follows:

[0021] PC, transparent encrypted file filter driver with file ending, WINDOWS system, driver configuration tool.

[0022] Step 1: Install the driver to the WINDOW system and start the driver

[0023] Step 2: Use the driver configuration tool to edit the rules for encrypted files. The specific content is as follows:

[0024] 1) What process: Use the name or fingerprint of the process to identify the process;

[0025] 2) What file: Use the file extension to identify the file;

[0026] 3) when to encrypt;

[0027] 4) Encrypt or decrypt when opening the file;

[0028] 5) Whether to encrypt when creating a new file;

[0029] 6) Whether to encrypt when overwriting files;

[0030] Step 3: Use the driver configuration tool to deliver the rules to the driver.

[0031] Step 4: The user uses his own software normally, the driv...

Abstract

The invention discloses a file transparent encryption method for adding an end-of-file. An end part is added on a file stored on a magnetic disk and a file-encrypted mark is placed. The algorithm of the file encryption can use the algorithm of any block encryption or byte encryption. The scheme is suitable for the encryption of all electronic files and is irrelevant to the formats of the electronic files.

Description

technical field [0001] The invention is applied in the field of data encryption, and is a method for transparently encrypting files. The transparent encryption implemented by adding file tails can realize data encryption and protection without changing the user's usage habits. This specification can be used for active and passive data security protection. Background technique [0002] Now with the implementation of informatization in various industries, while improving productivity, it also brings another kind of crime. Disasters caused by information leakage are fatal to both enterprises and individuals. For enterprises, it will bring a lot of economic losses. For individuals, it brings loss of reputation. For the government, the leakage of some confidential documents will have a serious impact on the country. [0003] In order to solve the problem of information security, there are many methods to solve information security. [0004] Some physical solutions exist, su...
