Problems solved by technology

[0004] The traditional file security authentication method has the following problems: First, the entire file is uploaded. When the file is relatively large, it takes a lot of time to upload and takes up more resources.
Second, it takes a long time and low efficiency to analyze and identify all the data in the uploaded files
Third, only the data information in the uploaded files is identified. However, with the continuous development of virus files, the data information in many virus files is the same as the data information in safe files, so the accuracy of the identification results obtained Low
Fourth, when there are multiple unknown files that need to be authenticated at the same time, they need to be queued up in sequence for identification, which is slow and inefficient

Abstract

The invention discloses a method and a device for detecting file security. The method includes extracting file features from files to be detected and determining the types of the extracted file features; determining artificial intelligent engine assessors according to the types of the file features and rating the file features by the aid of the determined assessors to acquire first rating results; comparing the first rating results to preset experience scores and determining security levels of the files to be detected. The method and the device have the advantage that problems of low speed and efficiency and poor accuracy of detection results of file security detecting procedures can be solved by the aid of the method and the device.

Description

technical field [0001] The invention relates to the technical field of the Internet, in particular to a method and device for detecting file security. Background technique [0002] At present, with the development of Internet technology, more and more virus files follow. Virus files are man-made special program codes, which have the following characteristics: self-replication ability, strong infectivity, and certain latency , specific trigger and very destructive. [0003] Traditional unknown file security authentication methods usually upload the entire file to the authentication server, and the authentication server analyzes and authenticates the data of the entire file to obtain the authentication result, thereby judging the security of the unknown file. [0004] The traditional file security identification method has the following problems: First, the entire file is uploaded. When the file is relatively large, it takes a lot of time to upload and takes up more resources...
