Abstract
The invention discloses a method for detecting sensitive tracks of uploaded files in a network. The method comprises the steps that a sensitive track set is set, sensitive words are searched for in the uploaded files and are extracted in sequence, the character positions where the sensitive words are located are extracted, the extracted sensitive words form a sensitive track to be detected according to the sequence of extraction, and matching between the sensitive track to be detected and all the sensitive tracks in the sensitive track set is carried out one by one; after matching is successful, whether the character pitch between every two adjacent sensitive words is smaller than or equal to the character pitch threshold value M is judged so that whether the sensitive track to be detected is the sensitive track in one uploaded file can be determined, and accurate research can be carried out on the sensitive words so that whether the sensitive track to be detected is the sensitive track in the uploaded file can be determined.
Description
Technical field
The present invention relates to secure file and upload field, particularly a kind of method of responsive track in Sampling network upload file.
Background technology
Along with the exploitation of network, user can freely communicate one's views on the net, can obtain more fully information although it is so, but also makes some bad speeches on network like this, serious even can raise fear, and will carry out strict monitoring like this for the file uploaded in network.
If each terminal server needs manually to carry out file content examination, so not only efficiency is very low but also waste of manpower resource, in order to raise the efficiency, at present, the method that each terminal is commonly used, for arrange keyword on the server, shields by carrying out keyword to upload file content with the effect reaching monitoring.
As application number " 200710308404.7 " denomination of invention " the keyword prevention method for Ill short message " the invention provides a kind of keyword prevention method for Ill short message; comprise the steps: that (1) operator or service provider provide a lists of keywords for Ill short message in advance, each entry of lists of keywords comprises two contents: the probability of occurrence of keyword, keyword; (2) user obtains full content or a subset of lists of keywords; (3) acquired keyword is merged in the lists of keywords of user mobile phone inside; (4) user mobile phone is according to the short message of the direct bag filter of lists of keywords containing keyword.The present invention effectively supplements the deficiency that original " keyword method " exists in practicality.
Application number " 201210479196.8 " denomination of invention " text filtering methods based on keyword weights " this application provides a kind of text filtering method based on keyword weights, and the method comprises the following steps: the weights calculating keyword; And based on the weights of calculated keyword, text is filtered; Wherein, the step calculating keyword weights comprises: judge whether described keyword is brand-new keyword, if so, then calculate the number of correct decision data in history decision data and the number of wrong decision data and comprise the number of correct decision data and the number of wrong decision data of described keyword; And calculate the weights of described keyword.In addition, present invention also provides a kind of text filtering system based on keyword weights.
Although can effectively be shielded flame by the weights of single keyword and keyword, so also make only to there is single keyword in some upload files and do not belong to the file conductively-closed too of bad message.
Summary of the invention
Technical matters solved by the invention is the method providing responsive track in a kind of Sampling network upload file, and the method determines whether comprise responsive track in upload file after utilizing responsive path matching to realize and verifying the responsive vocabulary in upload file.
The technical solution realizing the object of the invention is: a kind of method of responsive track in Sampling network upload file, specifically comprises the following steps:
Step 1, responsive lexicon is set, for storing responsive vocabulary;
Step 2, arrange responsive track collection according to the responsive vocabulary in responsive lexicon, wherein each responsive track is made up of at least two responsive vocabulary, and responsive vocabulary has aeoplotropism, and the character pitch threshold value between adjacent two responsive vocabulary is M, M is positive integer;
Step 3, monitoring upload file, search in upload file whether comprise responsive vocabulary, if comprise, performs step 4, otherwise do not comprise responsive track in this upload file;
Step 4, judge the quantity of the responsive vocabulary comprised in this upload file when only comprising a responsive vocabulary, then not comprise responsive track in this upload file; When comprising two or more responsive vocabulary, perform step 5;
Step 5, from this upload file, extract responsive vocabulary and current residing character position thereof in order, after the responsive vocabulary extracted is formed responsive track to be detected in order, perform step 6;
Step 6, concentrate each responsive track to mate with the responsive track in step 2 the to be detected responsive track obtained in step 5, when with a wherein responsive path matching success after, execution step 7;
Step 7, judge whether the character pitch in responsive track to be detected between adjacent two responsive vocabulary is less than or equal to character pitch threshold value M, if be less than or equal to, then judge that this responsive track to be detected is the responsive track in this upload file; Otherwise, judge not comprise responsive track in this upload file.
Preferred version further, in Sampling network upload file of the present invention responsive track method in, character pitch threshold value M is 20.
Preferred version further, in Sampling network upload file of the present invention responsive track method in, be extracted as in order in step 5 and search from file first character, extract belong in responsive lexicon the responsive vocabulary stored.
Preferred version further, in Sampling network upload file of the present invention responsive track method in, the responsive vocabulary extracted is formed responsive track to be detected by step 5 in order, is specially and responsive vocabulary is formed responsive track to be detected according to the sequencing extracted.
Preferred version further, in Sampling network upload file of the present invention responsive track method in, concentrate each responsive track to mate with the responsive track in step 2 the to be detected responsive track obtained in step 5, be specially: comprise responsive track to be detected in responsive track and be this responsive track to be detected and the success of responsive path matching.
The present invention compared with prior art, its remarkable advantage:
(1) by arranging responsive track collection, in upload file, search responsive vocabulary and responsive vocabulary and current residing character position thereof will be extracted in order, sequence of extraction is pressed in the responsive vocabulary extracted and forms responsive track to be detected, the responsive track of the every bar responsive track to be detected and responsive track concentrated mates the seek rate that can improve and associate keyword one by one.
(2) after the match is successful, whether the character pitch judging between adjacent two responsive vocabulary is again less than or equal to character pitch threshold value M to determine that whether responsive track to be detected is the responsive track in this upload file, can accurately search to determine that whether responsive track to be detected is the responsive track in this upload file to responsive vocabulary.
