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 to be construed as limiting 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 schematic flowchart of a network disk file control method according to an embodiment of the present invention, where this embodiment is applicable to a case where a login device is used to control a network disk file in a different location, and the method may be executed by a network disk file control apparatus, and specifically includes the following steps:
Generally, a user can download a corresponding file from a network disk, so as to facilitate offline processing of the file. The network disk can receive a downloading request of a user for the network disk file. After receiving a download request of the network disk file, the tracing information of the network disk file can be determined according to the specific content of the request.
The tracing and tracing information is used for representing intellectual property attribution of the file and corresponding information flowing out of the network disk. Therefore, the tracking and tracing information of the off-disk file can be determined by utilizing the time corresponding to the network disk file downloading request, the information of the requester and the network disk file. For example, the tracing information may include: advanced trace traceability information, comprising: ID of the network disk file, ID of a downloader, downloading time and storage path of the network disk file; and/or the primary tracing information comprises: the login name, name of the downloader, and the name of the network disk file.
And step 120, generating a download backup file for the network disk file.
In this embodiment, the trace source information may be secretly written into the network disk file. Since the network disk file may be downloaded by different users many times. Therefore, in this embodiment, a corresponding backup file is generated for the network disk file corresponding to the download request, so as to facilitate writing of the tracking and tracing information. For example, a temporary storage area may be set, and the network disk file may be copied in the temporary storage area to form a downloaded backup file.
And step 130, recording the tracking and tracing information in a network disk log, and generating an encrypted character string according to the tracking and tracing information.
The tracing information can be written into the network disk system log. Therefore, when the network disk file leaks, the tracing information recorded in the network disk log is used for tracing, and the intellectual property attribution problem of the network disk file can be effectively solved. Accordingly, in this embodiment, since the tracking and tracing information is written into the binary file of the network disk file, in order to avoid being deleted maliciously, the tracking and tracing information may be encrypted to generate an encrypted character string, so as to prevent a user from maliciously identifying the corresponding tracking and tracing information, and the encrypted character string may be generated according to the tracking and tracing information.
And 140, judging whether the network disk file is a binary document file or not, and determining a class corresponding to the office operation component according to the type of the network disk file when the network disk file is the binary document file.
For four file formats, namely doc, xls, ppt and pdf, files in the formats are stored in a binary mode. The corresponding content is added by directly modifying the file, so that the file is damaged or the information is lost. Therefore, in the embodiment, when the file is judged to be a binary document file, the encrypted character string can be written into the binary document file by using the office operation component in java. Because the classes corresponding to different types of files are different, the class corresponding to the corresponding office operation component needs to be determined according to the different types of files.
And 150, adding the tracking and tracing information attribute for the downloaded backup file by using the attribute addition class, and writing the encrypted character string serving as a new attribute value into the downloaded backup file.
And adding the tracking and tracing information attribute for the downloaded backup file by using the corresponding attribute addition class. And writing the encrypted character string as a new attribute value into a download backup file. For example, the tracing information may be used as an attribute name, and the corresponding encrypted string may be written into the download backup file as a new attribute value. For example, the new attribute and the corresponding attribute value may be added in an add (ID of the network disk file, encrypted string corresponding to the ID value) manner as a parameter of the class. Further, in order to prevent the attribute from being maliciously deleted, the attribute name may be encrypted and used as the attribute name.
And writing the tracking and tracing information attribute and the encrypted character string into a binary file, and taking the file as a download backup file. The user may download to a binary file that adds an encrypted string of trace traceability information. Once intellectual property disputes occur, the leaked files can be uploaded to the network disk system. The network disk system obtains corresponding tracing information after reading corresponding attributes and corresponding encrypted character strings and analyzing the attributes and the corresponding encrypted character strings, and can further obtain more information of the file by linkage query in the network disk according to the obtained tracing information, thereby providing corresponding reference data for determining intellectual property attribution and a leakage source.
In this embodiment, by receiving a network disk file downloading request, tracking and tracing information is determined according to the network disk file downloading request; generating a download backup file for the network disk file; recording the tracing information in a network disk log, and generating an encrypted character string according to the tracing information; judging whether the network disk file is a binary document file or not, and determining a class corresponding to a corresponding office operation component according to the type of the network disk file when the network disk file is the binary document file; adding a tracking traceability information attribute for the downloaded backup file by using the attribute addition class, and writing the encrypted character string as a new attribute value into the downloaded backup file; and providing the download backup file with the newly added attribute for a download requester. When the network disk downloads the file, the user-defined mark attribute is added to the file, and the encrypted file reverse tracking necessary information is used as an attribute value and is written into a corresponding backup file by using a class corresponding to the corresponding office operation component for being acquired by a downloading requester. The encrypted file reverse tracing necessary information can be analyzed to obtain corresponding tracing information. Compared with other modes, the method is not easy to identify, has stronger stability, has smaller computation amount, and can better meet the downloading requirement of the network disk file under the condition of meeting the requirement of file tracing.
In a preferred embodiment of this embodiment, the method may further include the following steps: and after downloading is finished, deleting the downloaded backup file. The method can effectively reduce the pressure of the backup files on the storage system, and can also avoid the problem that the source cannot be traced due to file issuing errors.
In another preferred implementation of this embodiment, the attribute adding class may be further used as the attribute of the newly added tracking and tracing information of the download backup file, and the encrypted character string is written into the download backup file as a newly added attribute value, which is specifically optimized as follows: and when the network disk file is a PPT file or a PDF file, setting a tracking and tracing information attribute for the downloaded backup file by using the attribute setting class, and writing the encrypted character string serving as a set attribute value into the downloaded backup file. For PPT and PDF files, the new attribute and the corresponding attribute value cannot be completed in add (ID of network disk file, encrypted character string corresponding to ID value). Therefore, it is necessary to implement the new attribute and the corresponding attribute value by using a set (ID of the network disk file, encrypted string corresponding to the ID value).
Example two
Fig. 2 is a schematic flowchart of a network disk file control method according to a second embodiment of the present invention. In this embodiment, the generating of the encrypted character string according to the tracing information may be specifically optimized as follows: determining an organization architecture level corresponding to the network disk file download requester, and generating an encryption character string according to the primary tracking and tracing information when the level is greater than a preset level standard; otherwise, generating an encryption character string according to the high-level tracing information.
Correspondingly, the method for controlling the network disk file provided by the embodiment specifically includes:
Certain computation amount and computation time are also needed for writing information into the binary file. Therefore, the amount of information written should be reduced as much as possible while ensuring that tracing can be accurately performed.
In general, a person with a higher position has a lower possibility of disclosure, and therefore, less tracing information can be selected according to such a situation. And the possibility of disclosure of the people with lower positions is higher, so that the hierarchy corresponding to the organization structure of the network disk file download requester on the network disk system can be firstly determined, and if the hierarchy is greater than the preset hierarchy standard, the people can be considered to have higher positions, and therefore, the encrypted character string can be generated only by adopting the primary tracking and tracing information.
Accordingly, if the requester for downloading the web disk file is smaller than the predetermined level standard, the requester may be a person with a lower position, and the possibility of disclosure is low. Therefore, it is necessary to generate an encrypted string using advanced traceback information.
In addition, the source of the network disk file can be considered, if the network disk file downloading requester is the creator and the system editor of the file, the possibility of disclosure is considered to be low, and therefore, the encryption character string can be generated by only adopting the primary tracing and tracing information. If the user is a common user, correspondingly, the high-level tracing information is adopted to generate the encrypted character string.
And 240, judging whether the network disk file is a binary document file or not, and determining a class corresponding to the office operation component according to the type of the network disk file when the network disk file is the binary document file.
And 250, adding a tracing information attribute for the downloaded backup file by using the attribute addition class, and writing the encrypted character string as a new attribute value into the downloaded backup file.
And step 260, providing the download backup file with the newly added attribute to the download requester.
In this embodiment, the generating of the encrypted character string according to the tracing information is specifically optimized as follows: determining an organization architecture level corresponding to the network disk file download requester, and generating an encryption character string according to the primary tracking and tracing information when the level is greater than a preset level standard; otherwise, generating an encryption character string according to the high-level tracing information. The increased data volume of the tracing and tracing information can be determined according to the actual situation of the actual downloading requester. And the written information amount is reduced under the condition of ensuring accurate tracing. Further, the calculation amount of data is reduced, and the calculation time is shortened.
EXAMPLE III
Fig. 3 is a schematic flow chart of a network disk file control method according to a third embodiment of the present invention. In this embodiment, the attribute addition class may be used as the attribute of the newly added tracking and tracing information of the downloaded backup file, and the encrypted character string may be written in the downloaded backup file as a newly added attribute value, which is specifically optimized as follows: and when the hierarchy is greater than the preset hierarchy standard, newly adding a single newly added tracking and tracing information attribute for the download backup file by using the attribute addition class, and writing all encrypted character strings into the download backup file as newly added attribute values of the single newly added tracking and tracing information attribute.
Correspondingly, the method for controlling the network disk file provided by the embodiment specifically includes:
And step 320, generating a download backup file for the network disk file.
And 340, judging whether the network disk file is a binary document file or not, and determining a class corresponding to the office operation component according to the type of the network disk file when the network disk file is the binary document file.
When there are a plurality of attributes, it is necessary to add an attribute and an attribute value by using a function for each attribute. Therefore, multiple call classes are required to be added, and thus a longer time is required to add completion. Since the high-level user has a low possibility of revealing the file, all the encrypted strings can be written into the binary file as a value of one attribute. So as to reduce the operation amount and the operation time. And the response speed is improved. Meanwhile, the network disk can still analyze all newly added encrypted character strings in the file and track and trace the source through the network disk log.
And step 360, providing the download backup file with the newly added attribute to the download requester.
In this embodiment, the attribute addition class is used as the attribute of the newly added tracking and tracing information of the downloaded backup file, and the encrypted character string is written into the downloaded backup file as a newly added attribute value, which is specifically optimized as follows: and when the level is greater than the preset level standard, newly adding a single newly added tracking and tracing information attribute for the downloaded backup file by using the attribute addition class, and writing all encrypted character strings into the downloaded backup file as the newly added attribute values of the single newly added tracking and tracing information attribute. The number of times of calling attribute addition classes can be reduced under the condition of ensuring accurate tracking and tracing. Further, the operation amount of data is reduced, and the operation time is shortened.
Example four
Fig. 4 is a flowchart illustrating a network disk file control method according to a fourth embodiment of the present invention. In this embodiment, the attribute addition class may be used as the attribute of the newly added tracking and tracing information of the downloaded backup file, and the encrypted character string may be written in the downloaded backup file as a newly added attribute value, which is specifically optimized as follows: and when the level is smaller than the preset level standard, adding at least two tracking and tracing information attributes for the downloaded backup file by using the attribute addition class, and writing the encrypted character string into the downloaded backup file as a corresponding attribute added attribute value of the at least two tracking and tracing information attributes.
Correspondingly, the method for controlling the network disk file provided by the embodiment specifically includes:
and step 410, receiving a network disk file downloading request, and determining the tracking and tracing information according to the network disk file downloading request.
And step 420, generating a download backup file for the network disk file.
And 430, recording the tracking and tracing information in a network disk log, determining an organizational structure level corresponding to the network disk file download requester, and generating an encryption character string according to the primary tracking and tracing information when the level is greater than a preset level standard.
And step 450, when the level is smaller than the preset level standard, adding at least two tracking and tracing information attributes for the downloaded backup file by using the attribute addition class, and writing the encrypted character strings corresponding to the at least two tracking and tracing information attributes into the downloaded backup file as the attribute added attribute values corresponding to the at least two tracking and tracing information attributes.
In order to prevent malicious or unintentional attribute deletion, in this embodiment, at least two tracking and tracing information attributes may be set when the download user level is smaller than a preset level standard or is a common user. Illustratively, the advanced tracing information can be randomly combined to generate a corresponding character string. And correspondingly writing the attribute adding classes to avoid the condition that the tracing information cannot occur due to malicious or unintentional attribute deleting operation, and reducing the times of calling the attribute adding classes. Meanwhile, the network disk can still analyze all newly added encrypted character strings in the file and track and trace the source through the network disk log.
In this embodiment, the attribute addition class is used as the attribute of the newly added tracking and tracing information of the downloaded backup file, and the encrypted character string is written into the downloaded backup file as a newly added attribute value, which is specifically optimized as follows: and when the level is smaller than the preset level standard, adding at least two tracking and tracing information attributes for the downloaded backup file by using the attribute addition class, and writing the encrypted character string into the downloaded backup file as a new attribute value corresponding to the at least two tracking and tracing information attributes. Malicious or unintentional attribute deletion operations are effectively prevented. And the number of times the attribute addition class is called can be reduced. Further, the calculation amount of data is reduced, and the calculation time is shortened.
