File encryption and decryption system based on c/s architecture and speaker recognition technology

Abstract

The invention discloses a file encryption and decryption system based on C / S architecture and speaker recognition technology. Users use traditional digital passwords or biometric voiceprint passwords to remotely log in to the system. People collect voice information on the spot to extract voiceprints, and finally perform judgment processing and encrypt or decrypt files. When encrypting or decrypting operations, first confirm the identity of the speaker on site, and only use the encryption algorithm or the corresponding decryption algorithm to encrypt or decrypt the file. When encrypting, add the encryption flag to the file header, and when decrypting, the file header Remove the encryption flag in and use the decryption algorithm to decrypt the file. The present invention combines voiceprint passwords carried by people with file encryption and decryption operations, and uses a remote server to lighten the client, not only providing users with a friendly and convenient operating environment, but also ensuring the security of the user's file data.

Description

Technical field [0001] The present invention relates to the technical field of encryption and decryption of documents, and more particularly to a file encryption decryption system based on C / S architecture and speaker recognition technology. Background technique [0002] With the development of Internet technology and the popularity of smartphones, more and more people use electronic equipment to record important information in daily life, such as billing, work arrangements, reports, etc., produce documents, slides, etc. The form of the series, but the problem of network security is also in time, hacker is seriously affected by people's daily lives, so the security issue of documents cannot be ignored. [0003] According to the famous Moore Law, the computer's calculation speed will continue to speed up. If the file encryption is used in the way of the traditional digital password, it is very likely that violent cracks in high-performance computers, and the security of user fil...

Problems solved by technology

[0002] With the development of Internet technology and the popularity of smart phones, more and more people use electronic devices to record important information in daily life, such as accounting, work arrangements, reports, etc., resulting in documents, slides, etc. series of files, but the problem of network security is also bothering us from time to time. The rampant behavior of hackers has seriously affected people's daily life, so the problem of file security can no longer be ignored.
