Problems solved by technology

Although there are many advantages to using SFTP, the protocol only guarantees the transmission process and does not perform any processing on the transmission content, which cannot meet the user's needs for dynamic desensitization of sensitive data

Embodiment Construction

[0022] The application will be described in further detail below in conjunction with the accompanying drawings.

[0023] In a typical configuration of the present application, the terminal, the device serving the network and the trusted party all include one or more processors (CPUs), input / output interfaces, network interfaces and memory.

[0024] Memory may include non-permanent storage in computer-readable media, in the form of random access memory (RAM) and / or nonvolatile memory, such as read-only memory (ROM) or flash memory (flashRAM). Memory is an example of computer readable media.

[0025] Computer-readable media includes both volatile and non-volatile, removable and non-removable media, and can be implemented by any method or technology for storage of information. Information may be computer readable instructions, data structures, means of programs, or other data. Examples of computer storage media include, but are not limited to, phase change memory (PRAM), static...

Abstract

The objective of the invention is to provide a dynamic desensitization scheme based on SFTP transmission. According to the scheme, the method comprises the following steps that: a reading request sentby an SFTP client is received through an SFTP proxy server, and the reading request is forwarded to an SFTP server by the SFTP proxy server; the SFTP server reads a target data packet corresponding to the reading request based on the reading request, and sends the target data packet to the SFTP proxy server; and the SFTP proxy server carries out dynamic desensitization processing on the target data packet, and returns the desensitized target data packet to the SFTP client. Compared with the prior art, the method has the advantages that dynamic desensitization of SFTP transmission data can berealized under the condition that the SFTP client and the server are not modified, so that the security of the data is further enhanced.

Description

technical field [0001] This application relates to the field of information technology, in particular to a dynamic desensitization technology based on SFTP transmission. Background technique [0002] SFTP (Secure File Transfer Protocol, Secure File Transfer Protocol) is a network transfer protocol that provides file access, transfer and management functions, and can provide a secure encryption method for transferring files. SFTP and FTP (File Transfer Protocol, File Transfer Protocol) have almost the same syntax and functions. In comparison, using SFTP is more secure because the SFTP transmission method uses encryption and decryption technology. Dynamic desensitization is a data desensitization technology for data extraction, data bleaching and dynamic masking for sensitive data. [0003] With the popularity of the Internet, the requirements for network security are getting higher and higher. As a network security file transfer protocol, SFTP will also gain considerable de...
