Business secret file exchange method

Abstract

The invention provides a business secret file exchange method. The method comprises the following steps: randomly extracting a business secret algorithm and a random key to encrypt the file, and thenuploading the encrypted file to a server connected to a public network through an application program; verifying the downloading identity by using multi-factor authentication, and downloading the fileon the client through an application program connection server; and encrypting the interaction information between the server and the client by using an encryption security strategy. As the file is uploaded and downloaded through the application program, the downloading path cannot be directly obtained from the outside; the uploaded file is encrypted by randomly extracting the business secret algorithm and the random key, so that the information in the file cannot be easily obtained even if the file is intercepted in a transmission process; the downloading identity is checked by using the multi-factor authentication, so that the downloading security can be greatly improved; and in addition, the file is encrypted by the encryption security strategy during the transmission, so that the information security in the file transmission process is improved.

Description

technical field [0001] This application relates to a method for exchanging business secret documents. Background technique [0002] A large amount of business confidential documents need to be exchanged between the main body and external suppliers, partners, etc. In the past, commercial confidential documents were mostly transmitted by media such as CDs and paper, which was inefficient and unable to be managed centrally, and there was a certain risk of leakage. Realizing the paperless transmission of commercial confidential documents through the network has a positive effect on shortening the document transmission cycle, improving work efficiency, reducing transmission costs, and promoting environmental protection. [0003] However, the transmission of commercial confidential documents through the network also has a certain risk of information leakage, such as sending files through emails in plain text, sending files through instant messaging software, downloading through U...

Problems solved by technology

[0003] However, the transmission of business secret files through the network also has a certain risk of information leakage, such as sending files through emails in plain text, sending files through instant messaging software, downloading through URL addresses, etc. The security of the files is very low, and it is very easy to be cracked and intercepted by hackers.
