Embodiment 1

[0039] figure 1 This is a flowchart of the method for tracing files on a network disk provided in Embodiment 1 of the present invention. This embodiment is applicable to the situation of tracing off-disk files. The method can be executed by a device for tracing files on a network disk, and specifically includes the following steps:

[0040] Step 110: Receive a file download request from the network disk, and determine the traceability information according to the file download request from the network disk.

[0041] Usually, the user can download the corresponding file from the network disk to facilitate offline processing of the file. The network disk can receive user download requests for files on the network disk. When a download request for a file on the network disk is received, the traceability information of the file on the network disk can be determined according to the specific content of the request.

[0042] The traceability information is used to represent the in...

Embodiment 2

[0064] figure 2 This is a flowchart of the method for tracing network disk files provided in the second embodiment of the present invention. This embodiment is optimized on the basis of the above-mentioned embodiment. In this embodiment, the generation of an encrypted string according to the traceability information can be specifically optimized as follows: determining whether the download requester of the network disk file is a file creator. When the file creator or editor is a file creator or editor, an encrypted string is generated based on the primary traceability information; otherwise, an encrypted string is generated based on the advanced traceability information.

[0065] Correspondingly, the network disk file tracing method provided in this embodiment specifically includes:

[0066] Step 210: Receive a file download request from the network disk, and determine the traceability information according to the file download request from the network disk.

[0067] Step 2...

Embodiment 3

[0080] image 3 This is a flowchart of the method for tracing network disk files provided in Embodiment 3 of the present invention. This embodiment is optimized on the basis of the above-mentioned embodiment. In this embodiment, the type of traceability information is used as the name of the newly added attribute, and the corresponding encrypted character string is written as the content of the attribute into the extensible markup language file , the specific optimization is: when the download requester is the creator or editor of the file, use a single newly added traceability information attribute as the name of the newly added attribute, and use all encrypted strings as the single newly added traceability information attribute as the attribute content into the Extensible Markup Language file.

[0081] Correspondingly, the network disk file tracing method provided in this embodiment specifically includes:

[0082] Step 310: Receive a file download request from the network ...

Abstract

The embodiment of the present invention discloses a network disk file tracing method, device, network disk and storage medium. Wherein, the method includes: receiving a file download request from a network disk, and determining the traceability information; recording the traceability information in the network disk log, and generating an encrypted character string according to the traceability information; generating a download backup file for the network disk file; Determine whether the network disk file is based on the Office Open XML file, and if so, decompress the downloaded backup file, and obtain the extensible markup language file of the file customization attribute in the document attribute folder therein; in the extensible markup language Add a new attribute to the file, use the type of traceability information as the name of the newly added attribute, and write the corresponding encrypted string as the attribute content into the Extensible Markup Language file; write the written Extensible Markup Language file as the boot target Boot the Extensible Markup Language file; compress it to generate a download file for users to download and use.

Description

technical field [0001] Embodiments of the present invention relate to the technical field of network disks, and in particular, to a method, device, network disk, and storage medium for tracing files of network disks. Background technique [0002] Netdisk is an online storage service launched by Internet companies. The network disk system room divides a certain disk space for users, provides file storage, access, backup, sharing and other file management functions for users for free or for a fee, and has advanced disaster recovery backup around the world. Users can regard the network disk as a hard disk or U disk placed on the network. Whether it is at home, work or any other place, as long as it is connected to the Internet, the files in the network disk can be managed and edited. There is no need to carry it with you, and you are not afraid of losing it. [0003] Enterprise data security is particularly important. The security management of files on the network disk is r...
