Computer defense system and method based on data depth association

Abstract

The invention discloses a computer defense system and a computer defense method based on data depth association, which not only utilize and encode context information among contents in each document in a folder, but also utilize and encode context information among contents of a plurality of documents in the folder through a two-stage semantic understanding model. Therefore, the content correlation among the documents is fully utilized. Furthermore, context decoding is also realized through a converter class function value and a decoder hidden state mechanism at a decoding level, so that the accuracy of regression is improved, and the training speed and convergence are also improved. Therefore, each document in the file can be encrypted more accurately, and the security of file transmission is improved.

Description

technical field [0001] The present invention relates to the field of computer defense, and more specifically, relates to a computer defense system and defense method based on deep correlation of data. Background technique [0002] At present, most enterprises mainly conduct information security protection work from both the external network and the internal network. The external network mainly uses security equipment such as firewalls and anti-attacks for security information protection to prevent hackers or external visitors from entering the enterprise intranet to steal core data within the enterprise. However, scandals such as important data leaks in most companies today are mainly caused by internal employees actively leaking secrets, and internal employees can leak important information through USB flash drives and email transmissions. [0003] Some existing technologies detect that data is downloaded from the computer intranet or transmitted to the external network IP...

Problems solved by technology

However, most of the important data leaks and other scandals in most companies today are mainly caused by internal employees actively leaking secrets, and internal employees can leak important information through USB flash drives and mail transmissions, etc.

[0003] Some existing technologies detect that data is downloaded from the computer intranet or transmitted to the external network IP, automatically encrypting the files to be transmitted for the purpose of security defense, but often in the transmitted folder There are multiple documents, some documents are private and need to be encrypted, and some documents are non-private and do not need to be encrypted. Unified encryption will affect normal file transmission and use. Therefore, before encryption, how to encrypt files It is very important to identify the documents in the folder
