Detailed Description
The present invention will be described in further detail with reference to the accompanying drawings and examples. It is to be understood that the specific embodiments described herein are merely illustrative of the invention and are not limiting of the invention. It should be further noted that, for the convenience of description, only some of the structures related to the present invention are shown in the drawings, not all of the structures.
Example one
Fig. 1 is a flowchart of a method for downloading a protected document according to an embodiment of the present invention, where the embodiment is applicable to a case of downloading an online document with data protection rights, and the method may be executed by a downloading device for protecting a document, and may be integrated in a network disk, and specifically includes the following steps:
The user can initiate a download request of a specific document in the online document system by operation, the network disk receives the download request, and determines the file ID of the downloaded document and the user ID initiating the download request according to the download request. And determining whether the document is a protected document by searching the metadata of the document according to the corresponding document ID. The protected document is a special document format, is mainly applied to a multi-person collaborative editing scene, and is characterized in that the protected document is invisible to each editor except for a content part with a right. By using the mode, the data safety can be protected as much as possible under the scene of realizing the simultaneous collaborative editing of a plurality of persons.
In step 120, when the document is protected, it is checked that the user initiating the download request has a partial editing right to the protected document.
When the system document is determined to be a protected document, firstly, whether the user has a partial editing right to the protected document is judged according to the user ID of the downloading request, and the partial editing right can be that the user has an editing right to partial content in the protected document. And if the partial editing authority is not provided, directly refusing the downloading request.
And step 130, when the protected document has partial editing rights, generating a download template for the protected document.
Since the protected document has content for protecting the downloading user, the protected document cannot be directly provided for the user to download. In this embodiment, a download template may be generated for the protected document, and the download template retains elements such as the style and page layout of the protected document. Such as font, font size, segment spacing, etc., and retains the corresponding subject name and part of the outline and directory contents. The specific paragraph or cell style is also preserved and correspondingly marked. Such as: paragraph numbers or cell locations, etc. Illustratively, the generating a download template for the protected document may include: analyzing the structure of the protection document; acquiring the style and page layout of each element in the structure; and generating a downloading template according to the style and the page layout of each element. The protected document is divided into a plurality of elements according to the structure, wherein the elements can comprise: in the case of a text editing type document, the elements may be chapters, paragraphs, or a sentence. The granularity of the elements can be set automatically according to actual conditions or manually by a user. The style and corresponding page layout of each element is then read. And then generates a corresponding download template.
In this embodiment, a region-right model may be set for the protected document, where the region-right model is used to indicate which regions in the protected document have rights by editors, and since the rights of each editor are different and the corresponding editing regions are also different, the region-right model of each editor is also different. Alternatively, the region-rights model may be a tree structure. The general node is a title and a directory, then each child node is a chapter, and the grandchild node is a paragraph. By utilizing the tree structure, the corresponding authority area can be quickly found. Illustratively, the region-rights model in the protection document may be generated by: inquiring metadata of the protected document to obtain the minimum authority element unit of the user in the protected document; and generating a tree region-authority model according to the minimum authority element unit and the structure of the protection document. The minimum authority element unit may be a minimum region range corresponding to the authorization, and may be a cell, or a row, a sentence, or a paragraph. The corresponding region-authority model can be generated quickly by the method.
And 150, acquiring corresponding authorized content according to the region-authority model, and embedding the authorized content into a download template to generate a security document.
And determining the result of the corresponding region according to the traversal region-authority model, acquiring the contents in the region, embedding the contents into the download template, reserving the region contents with the authority of the current user in the download template, and transferring the download template to generate the security document. By using the tree region-authority model, the region with the authority can be conveniently and quickly positioned. Meanwhile, compared with the whole document, the region with the authority is relatively less, so that the safety document can be generated quickly in the mode.
The security document may be a document that masks off the content of the area that the user does not have rights to download, and after the security document is generated, a download request may be directed to the security document. The user can download the security document, and can conveniently edit the protection document under the condition that the user leaves the disk.
The embodiment of the invention receives a downloading request of a system document, and judges whether the system document is a protection document according to the downloading request; when the document is protected, checking that a user initiating a downloading request has partial editing right on the protected document; when partial editing rights exist, a downloading template is generated for the protection document; acquiring a region-authority model of the user in the protected document; acquiring corresponding authorized content according to the region-authority model, and embedding the authorized content into a download template to generate a security document; and directing the downloading request to the security document so that the user downloads the security document. The copy of the protected document style can be realized by utilizing the download template, the regional content with the authority of the user is obtained through the regional-authority model of the user, and the regional content is embedded into the download template to generate the safe document for the user to download. The editor may download to the secure document consistent with the actual editing of the online document and may view and edit the secure document in an off-disk environment. By processing the sensitive information of the protected document during downloading, the sensitive information can be prevented from leaking under the condition that an editor is convenient to leave the protected document, and the data security of the protected document is ensured.
Example two
Fig. 2 is a flowchart illustrating a method for downloading a protected document according to a second embodiment of the present invention. In this embodiment, the generating of the region-right model according to the minimum right element unit and the structure of the protected document is specifically optimized as follows: judging whether each authority element is in a collaborative editing state at present; and copying the authority elements in the collaborative editing state, adjusting the copied authority elements as new areas, and inheriting the original authority.
Correspondingly, the method for downloading the protected document provided by the embodiment specifically includes:
In step 220, when the document is protected, it is checked that the user initiating the download request has a partial editing right to the protected document.
And 240, inquiring the metadata of the protected document to obtain the minimum authority element unit of the user in the protected document.
Since the protection document supports a plurality of editors to edit simultaneously, it is possible that a plurality of editors have editing rights to the same editing area. Therefore, when a download request is made, it is necessary to determine whether each corresponding right element and right area are in a collaborative editing state. For example, whether the editing area of the active editor is the same as the authority element can be judged by checking whether the active editor exists in the protected document currently, and if the active editor exists in the protected document currently, the authority element is determined to be in a collaborative editing state currently.
And step 260, copying the authority elements in the collaborative editing state, adjusting the copied authority elements as new areas, and inheriting the original authority.
The downloaded online file should keep more information as much as possible, and if the rights element is currently in the collaborative editing state, the editing content of other editors should be kept as much as possible. Therefore, in the present embodiment, one rights element is additionally copied and the original rights are integrated. By the method, the downloaded online document can keep the authority, and simultaneously, the editing contents of other editors are also stored, so that the downloading user can conveniently and fully refer to the editing contents of other editors.
And 270, acquiring corresponding authorized content according to the region-authority model, and embedding the authorized content into a download template to generate a security document.
In this embodiment, a region-rights model is generated according to the minimum rights element unit and the structure of the protected document, and is specifically optimized as follows: judging whether each authority element is in a collaborative editing state at present; and copying the authority elements in the collaborative editing state, adjusting the copied authority elements as new areas, and inheriting the original authority. When the authority area in the online document is edited by other editors, the editing contents of other editors are reserved, so that the downloading of the writing contents of other editors by a user is facilitated, and the working efficiency is improved.
EXAMPLE III
Fig. 3 is a flowchart illustrating a downloading method of a protected document according to a third embodiment of the present invention. In this embodiment, the method may further include the following steps: and recording the association relation between the security document and the region-authority model. Receiving the uploaded security document, and determining a region-authority model and a corresponding protection document according to the association relation; acquiring a modified region according to the region-authority model; and writing the corresponding content of the modified area into the protection document.
Correspondingly, the method for downloading the protected document provided by the embodiment specifically includes:
In step 320, when the document is protected, it is checked that the user initiating the download request has a partial editing right to the protected document.
And step 330, generating a download template for the protected document when the protected document has partial editing rights.
And 350, acquiring corresponding authorized content according to the region-authority model, and embedding the authorized content into a download template to generate a security document.
And step 360, recording the association relationship between the security document and the region-authority model.
The security document may be a copy of the online document, and thus, in the system, the relationship between the security document and the online document needs to be recorded. Since the region-authority model expresses the relation of downloading the user-online document, the safety document and the region-authority model are recorded, so that the later period tracing is facilitated,
The downloader may perform off-disk editing on the secure document and, after the off-disk editing is completed, re-upload the secure document to the online document system. The corresponding region-authority model and the corresponding protection document can be determined according to the incidence relation recorded in the previous steps.
And determining the region which can be edited by the downloader by using the region-authority model, and determining the region modified by the downloader according to the content change of the editing region.
And reading corresponding content from the modified area in the security document, and correspondingly writing the corresponding content into a protection document in the online document system. The merging of the security document and the protection document can be automatically realized. Therefore, the downloading user does not need to manually upload the edited content to the protected document or generate a plurality of versions of content.
For example, the writing the modified corresponding content of the area into the protection document may include: judging whether the modified area has cooperative writing content; and when the collaborative write-in content exists, generating a composite reference area according to the area-authority model, and writing the modified content corresponding to the area into the composite reference area of the protected document. If the downloaded security document includes contents written by other editors in the editing area, the copied right elements are added in the area-right model when the security document is generated. Therefore, in this embodiment, a composite reference region is generated using a region-authority model, the composite reference region including: the editing area of the original other editors and the editing area used by the downloader. By the method, the edited contents of a plurality of editors can be embodied in the protected document, so that the edition can be determined and approved finally.
The present embodiment adds the following steps: the following steps are added: and recording the association relation between the security document and the region-authority model. Receiving the uploaded security document, and determining a region-authority model and a corresponding protection document according to the association relation; acquiring a modified region according to the region-authority model; and writing the corresponding content of the modified area into the protection document. The method and the device have the advantages that according to the safety document uploaded by the downloader, the content edited by the downloader from the disk is automatically integrated into the protection document, so that the downloading user does not need to manually upload the edited content into the protection document, and does not need to generate a plurality of versions of content. The working efficiency of using the protected document to edit from the disk is further improved.
