Transparent file encryption technology

Abstract

The invention discloses a transparent file encryption technology, comprising a safe area setting module, a safe area importing module, an encryption algorithm setting module, an automatic encryption and decryption module, an automatic backup module, an automatic invalidation module, a transmission path setting module, a safe area exporting module, a data processing module, a private key setting module, a file matching module, a private key detection module, a private key matching module, a file replacement module, a file deletion module, a file environment detection module and a transmission path detection module. According to the technology, the security of a secret file before and after loss can be ensured; the efficiency of an encryption and decryption algorithm is relatively high; the encryption and decryption speed is relatively fast; and the program portability is high. The technology can be applied to storage media such as local hard disks and cloud disks of different brands, and the technology has very high flexibility. Both local data and cloud data can be protected effectively. In the process of automatically synchronizing the secret file from the local to the cloud, the transmission data is ciphertext; and attacks such as sniffing and packet capture can be effectively defended.

Description

technical field [0001] The invention relates to the technical field of file encryption, in particular to a transparent file encryption technology. Background technique [0002] Transparent encryption technology is a file encryption technology that has emerged in recent years to meet the needs of enterprise file confidentiality; the so-called transparent means that it is unknown to the user; when the user opens or edits the specified file, the system will automatically encrypt the file. Encrypt unencrypted files, and automatically decrypt encrypted files; files are ciphertext on the hard disk and plaintext in memory; once they leave the use environment, they cannot be opened because the application cannot get the service of automatic decryption, so it is protected Effect on file content. [0003] In recent years, with the popularization of the network and the continuous improvement of network technology, the era of big data has followed, and the concept of "cloud" has also e...

Problems solved by technology

[0003] In recent years, with the popularization of the network and the continuous improvement of network technology, the era of big data has followed, and the concept of "cloud" has also emerged; due to the convenience and long-term advantages of cloud technology, more and more Users tend to transfer personal private data to the cloud for storage; however, since personal private data is stored in plain text on the cloud, this gives criminals an opportunity; once the cloud server is compromised or the user's personal password is stolen, Personal data will be fully exposed; coupled with the insecurity of plaintext storage on traditional hard disk media, the promotion of transparent encryption technology is imminent
