Description
Technical field
The present invention relates to information security of computer network technical field, particularly relate to the network public-opinion of a kind of customizable reduction
Preservation of evidence method.
Background technology
Network public sentiment information belongs to a class of electronic evidence, Internet era network public sentiment information impact be huge,
Negative public feelings information may be little to affecting individual mood, fame or privacy, big to affecting the existence of enterprise, social order very
To national security.And public feelings information has and easily distorts the feature easily loss, so proactive preservation should be fixed by network public-opinion
Information, just can be active in following right-safeguarding.
Generally electronic data to meet certain requirement just can become electronic evidence, wherein extracts fixing electronic data and is formed
Judicial expertise report be a kind of important evidence.In Vehicles Collected from Market, network public sentiment information is all doing in Internet firm of a lot of family
Monitoring, but they are only merely and include public feelings information on network, and so can not be that evidence is fixed, so before
Any company is not had to reach the requirement that evidence is fixing.As being available for the electronic evidence that the administration of justice is accepted and believed, its operation side must have phase
The electronic evidence judicial expertise qualification closed, secondly the pattern for electronic evidence also has special requirement.
Network public sentiment information and effective electronic evidence have a following difference:
(1), in the form of expression, network public sentiment information is the web page files extending the types such as entitled html, htm or php, and
Effective electronic evidence is screenshot capture, and picture to comprise following key element: in application framework, public feelings information address, message
Hold and protection servicer local zone time.Such pictures just contains the source of public feelings information, content, extracting method and time
Etc. content.And web page files itself only carries the information of message content, evidential effect is the lowest.
(2) it is plurality of pictures for being showed more than electronic evidence corresponding to the network public sentiment information of a screen, picture pair
Answer each screenshot capture of keypad page turning key.
Electronic evidence should include the key elements such as source, extracting method, content and time, the net that network collection engine collects
Page contains only content, and generally in have disappearance, act of law is weak a lot.At present, the API that calling Windows provides enters
Row sectional drawing, can only change into graphic form info web, is also not include the key element that all electronic evidences should possess.
Public feelings information filters and refers to according to automatic need of condition such as public sentiment source, Sentiment orientation, information issuing time, key words
Network public-opinion to be saved from damage.The not all public feelings information collected is required for carrying out the public sentiment of the preservation of evidence, such as front
Information.The rate of false alarm of presently disclosed emotion distinguished number is the highest, and consequence can cause negative public feelings information to be missed and testify
According to saving from damage.Internet public feelings information belongs to the not reproducible data of remote digital equipment, is characterized in easily distorting easily lossing, because of
This public feelings information from collected, filter, should be a continuous print action to the preservation of evidence, the speed of filtration needs and the speed gathered
Degree coupling, otherwise may cause evidence be tampered or loss.
Summary of the invention
The technical problem to be solved is to provide a kind of network public-opinion preservation of evidence method of customizable reduction, should
Method have employed automatic emotion distinguished number and full-text search algorithm, and intelligent filters out advertisement and not a theme relevant information, make
Calling program focuses on information content, improves discrimination；User can also configure public feelings information filtering rule simultaneously, it is intended that protect
The condition of full public feelings information, screens public feelings information, thus realizes user according to public sentiment source, Sentiment orientation, information
The network public-opinion needing to save from damage is reduced in the customization of the condition such as issuing time, key word, and is provided with for judicial safeguarding-rights act afterwards
The electronic evidence of effect.
For solving above-mentioned technical problem, the technical solution used in the present invention is: the network public-opinion of a kind of customizable reduction
Preservation of evidence method, comprises the following steps:
1) public feelings information is gathered；
2) to the public feelings information gathered, public feelings information filtration is carried out according to the public feelings information filtering rule of user setup, and
Automatic emotion distinguished number and full-text search algorithm is used to carry out filtration treatment；
3) public feelings information is carried out dictionary coupling；
4) the dictionary public feelings information that the match is successful is carried out screen shot and preserved.
The technical scheme optimized further is described step 2) in automatic emotion distinguished number mainly comprise the steps that
A, for gather public feelings information carry out participle extraction；
B, for extract participle carry out vocabulary extraction；
C, according to positive emotion dictionary and negative emotion dictionary the vocabulary of extraction carried out emotion word coupling go forward side by side market sense
Word front, negative, neutral value category judge；
D, reading vocabulary, and carry out front public opinion, negative public opinion, the judgement of neutral public opinion according to emotion score value.
The technical scheme optimized further is described step 2) in full-text search algorithm mainly comprise the steps that
A, for gather public feelings information carry out participle extraction；
B, the participle of extraction is stored in dictionary；
C, carrying out Keywords matching judgement, the match is successful then carries out screen shot process, mates unsuccessful, abandons
Process.
The technical scheme optimized further is described step 4) in the dictionary public feelings information that the match is successful is shielded
Curtain screenshotss preservation mainly comprise the steps that
A, establishment run sandbox, i.e. create a running environment to load public feelings information；
B, split screen sectional drawing, be i.e. carried on screen whole public feelings information and carry out sectional drawing process；
C, preservation sectional drawing, i.e. load upper signature to sectional drawing or watermark carry out data preservation.
Use and have the beneficial effects that produced by technique scheme: present invention employs automatic emotion distinguished number with complete
Literary composition searching algorithm, intelligent filters out advertisement and not a theme relevant information so that program focuses on information content, improves identification
Rate；User can also configure public feelings information filtering rule simultaneously, it is intended that the condition of public feelings information to be saved from damage, enters public feelings information
Row filter, thus realize user and reduce need according to condition customizations such as public sentiment source, Sentiment orientation, information issuing time, key words
Network public-opinion to be saved from damage, and provide effective electronic evidence for judicial safeguarding-rights act afterwards.The present invention is that one is applied to
Network public-opinion preservation of evidence technology in public sentiment monitoring system or acquisition system, has an advantage in that:
(1) save process from damage and electronic evidence meets Ministry of Public Security's standard of perfection " digitizer proof data finds to extract solid
Determine method " GA/T 756-2008.
(2) network public-opinion collection and the preservation of evidence are automatically performed.
(3) can originate according to public sentiment, Sentiment orientation, information issuing time, the customization of the condition such as key word are reduced needs and are saved from damage
Network public-opinion.
