Embodiment
Below will combine accompanying drawing and embodiment to specify embodiment of the present invention, how the application technology means solve technical matters to the present invention whereby, and the implementation procedure of reaching technique effect can make much of and implement according to this.Need to prove that only otherwise constitute conflict, each embodiment among the present invention and each characteristic among each embodiment can mutually combine, formed technical scheme is all within protection scope of the present invention.
In addition; Can in computer system, carry out in the step shown in the process flow diagram of accompanying drawing such as a set of computer-executable instructions, and, though logical order has been shown in process flow diagram; But in some cases, can carry out step shown or that describe with the order that is different from here.
First embodiment
Fig. 1 is according to the schematic flow sheet of the clipbook control method of first embodiment of the invention, please refer to Fig. 1, specifies each step of this embodiment.
In the embodiment of the invention, related document is a document of following OpenDocument Format (ODF) standard format.The document is mainly by content.xml, setting.xml, meta.xml, stypes.xml file, and Pictures and META-INF file are formed, and can check its inner structure through using the decompression TO.
Anti-reproduction switch property value is called for short CanCopyOut, and it is kept in the setting.xml file of document.Because Openoffice.org provides the primary support of the document of ODF standard format, and it is free to increase income, with this platform that supports as the embodiment of the invention.
Because anti-reproduction switch property value is to be stored in the XML file, therefore can relate to the parsing access procedure of XML file.Load a file in embodiments of the present invention and all can carry out parse operation the xml file with the preservation file.
Being provided with of anti-reproduction switch property value, come attribute CanCopyOut is carried out assignment owing to provide second development interface, user that function setPropertyValue function can be set through the attribute in the VBA macro call.
If judged result is not for, then directly with the content stores of duplicating or shearing in the region of memory of system's shear plate and/or program.
Particularly, when opening file,, will prevent that reproduction switch attribute CanCopyOut value reads in internal memory, obtain the property value of CanCopyOut attribute through the getPropertyValue function through the setting.xml file is resolved.If the property value of CanCopyOut attribute be true, i.e. TRUE, then the expression institute content of duplicating or shearing is not done encryption, direct with the content stores of duplicating or shearing in the region of memory of system's shear plate and/or program.
If judged result is for being, then the content of duplicating or shearing is encrypted, with the content stores after encrypting in the region of memory of system's shear plate and/or program.
Particularly, when opening file,, will prevent that reproduction switch attribute CanCopyOut value reads in internal memory, obtain the property value of CanCopyOut attribute through the getPropertyValue function through the setting.xml file is resolved.If the property value of CanCopyOut attribute is false; Be FALSE; Then expression institute's content-label of duplicating or shearing is copy and need carries out encryption, then the content (also can be described as service data) of duplicating or shearing is done encryption and will encrypt after the content stores of duplicating or shearing in the region of memory of system's shear plate and/or program.
Need to prove, in homologous series software or the same software, with the content stores after encrypting in the region of memory of procedure division.For example: the duplicate paste operation of the software suite OpenOffice.org of office between this software suite all is that region of memory through procedure division exchanges the content (also being called service data) of duplicating stickup.Therefore the service data encryption that only need will put into the region of memory of procedure division can reach the purpose that restriction is duplicated.In the present embodiment, store the content of having encrypted through the region of memory of the procedure division created by the application program of this software, the region of memory of this division is exclusively enjoyed by application program, rather than the employed shared drive of system clipboard zone.
Need to prove,, the encryption indicator position can be set in the content of having encrypted, carried out cryptographic operation to represent this content for homologous series software or same software.
In addition, for different series software, with the content stores after encrypting in system clipboard.
Need to prove that the content of duplicating or shearing in the present embodiment can be service datas such as text, form, picture and/or object.
Behind completing steps 120, can also further carry out the operation of step 130.
Particularly, the content that will encrypt is carried out format manipulation based on the custom coding form, with the institute's content stores of duplicating or shearing after the format in the region of memory of system's shear plate and/or program.
The content of not encrypting is foreclosed, adopt self-defining specific coding form (except the universal coding form) that the content that will encrypt is formatd processing, this self-defining specific coding form is supported homologous series software or same software.
For example, can self-defined a kind of like this coded format FormatA, this form is made up of file header, data and end-of-file.A kind of self-defining data structure is deposited at the file header place, and this kind data structure comprises format identification (FID) information and message length; File data is on BMP coded format basis, to remove its remaining partial data in file header part back; End-of-file is deposited the identifier of homologous series software or same software.Increase corresponding resolving at homologous series software or same software.
After formaing according to form FormatA, carry out in homologous series software or same software and to call the corresponding resolving of FormatA form when pasting and resolve reduction.When the different series software executing is pasted, owing to lack analytic method,, also can't discern even clipbook has data to this form, therefore can't paste.
In addition, can also carry out format manipulation to the content that need not encrypt based on the universal coding form, with the format after content stores in the procedure sharing region of memory.
Said universal coding form comprises the coded format of the coded format of the TXT, HTML or the RTF that are directed against content of text, the GDI METAFILE that is directed against picture and BMP and the coded format that is directed against object.
Because when duplicating the service data of clipbook; Service data in the clipbook is formatd according to certain universal coding, and universal coding can be the TXT to content of text, the coded format of HTML or RTF; Can make the service data after the format can be through this operation by each application identification; Therefore only a content that needs need not to encrypt formats, and the service data of copy is foreclosed, and promptly can prevent to duplicate.
For example, therefore Openoffice.org can can reach the purpose that restriction is duplicated through formative result is screened with the shared drive zone that deposits system clipboard behind the content formatting that duplicates in when carrying out replicate run.
More specifically; Obtain service data earlier; Service data can be service datas such as text, form, picture, object, obtains the property value of CanCopyOut attribute then through the getPropertyValue function, if the CanCopyOut property value is FALSE; Expression current document content has been labeled as copy, empties the clipbook of current system; Do not carry out the service data of duplicating operation, stop it writing system clipbook shared drive zone as a result according to the universal coding format;
Particularly; When the user carries out paste operation to the said content of duplicating or shearing in the region of memory of the program of being stored in, can be through judge whether the content of duplicating or shearing of the said content of duplicating or shearing based on said encryption indicator position for having encrypted.
Need to prove that because the document that restriction is duplicated can't be toward the system clipboard store data, system clipboard is empty, therefore relevant with system clipboard paste operation is all disabled.This step is meant the decrypting process to the encrypted content in the region of memory that is stored in the program in homologous series software or same software.
Fig. 2 for according to first embodiment of the invention carry out the schematic flow sheet of paste operation to duplicating or shear content, please refer to Fig. 2, specify each step below.
Step 210 is obtained the content that the institute in the region of memory of program duplicates or shears, and judges whether the content of duplicating or shearing of a content for having encrypted that institute duplicates or shears based on the encryption indicator position.
If judged result is not for, promptly the encryption indicator position be false, then direct the content of duplicating or shearing is carried out paste operation.If judged result is for being, promptly the encryption indicator position is true, then gets into step 220, the operation of execution in step 220.
Step 220 judges whether the content that the institute of having encrypted duplicates or shears is deciphered based on anti-reproduction switch attribute.
If judged result is for being, then to the content of duplicating or shearing carry out decryption processing to carry out paste operation.
Particularly, anti-reproduction switch property value is false, and promptly the CanCopyOut property value is False, and the service data of procedure sharing region of memory is carried out decryption processing, carries out paste operation then.
If judged result is not for, then the content of duplicating or shearing is not carried out decryption processing, withdraw from paste operation.
Particularly, anti-reproduction switch property value is true, and promptly the CanCopyOut property value is True, does not make decryption processing, and prompting user source content has been limited to duplicate when the user carries out paste operation.
In addition; Can also be through judging that whether containing the encryption indicator position in the said content of duplicating or shearing judges whether the content of duplicating or shearing encrypts; The format of content processing mode of perhaps duplicating or shearing through judging judges whether the content of duplicating or shearing has encrypted, gives unnecessary details no longer in detail at this.
Need to prove that the embodiment of the invention can be used for Openoffice.org and based on various extension products that Openoffice.org researched and developed.Its external member inner module: Writer (text document), Impress (PowerPoint), Calc (electrical form) all can realize identical effect.
The inventive method is through realizing the protection to file content to the encryption of Contents of clipboard with to the control of content format; Reach the purpose that file content is not replicated under the unauthorized situation; The present invention has expanded the application of the synergetic office work in the internet; Improved protection, can prevent that file content is replicated under the unauthorized situation file content.
