However, the existing traceability method can only use the digital watermark method, but this method can only record the information at the time of download, such as: the IP address of the downloaded file and the user name of the network disk, etc.
However, this method cannot indicate the subsequent file transfer process information
Unable to trace the source of document leakage

Embodiment 1

[0031] figure 1 The flow chart of the off-disk file traceability method provided by Embodiment 1 of the present invention, this embodiment is applicable to the situation of traceability of the operation and transfer of files downloaded from the network disk, the method can be executed by the off-disk file traceability device, off-disk file The disk file traceability device can be realized by software, and can be integrated in the terminal that downloads the off-disk file and operates the off-disk file, specifically including the following steps:

[0032] Step 110, when receiving the running operation request of the off-disk file, detect whether the log recording process of the off-disk file is running normally, the off-disk file log is generated by the network disk when the off-disk file is downloaded, and is encapsulated in the off-disk file , and implant the corresponding off-disk file log recording process when the off-disk file download is completed.

[0033] In this embo...

Embodiment 2

[0045] figure 2 It is a schematic flowchart of the off-disk file tracing method provided by Embodiment 2 of the present invention. This embodiment is optimized on the basis of the above-mentioned embodiments. In this embodiment, when the running operation is editing, the off-disk file log running in the off-disk file operation sandbox is written into the running Operation information, the specific optimization is: generate a new version of the running log, and write the running operation information in the new version of the log.

[0046] Correspondingly, the off-disk file traceability method provided in this embodiment specifically includes:

[0047] Step 210, when receiving the running operation request of the off-disk file, detect whether the log recording process of the off-disk file is running normally, the off-disk file log is generated by the network disk when the off-disk file is downloaded, and is encapsulated in the off-disk file , and implant the corresponding of...

Embodiment 3

[0055] image 3 It is a schematic flowchart of the off-disk file tracing method provided by Embodiment 3 of the present invention. This embodiment is optimized based on the above embodiments. In this embodiment, the off-disk file is specifically optimized as: off-disk encrypted file, and the off-disk encrypted file includes: off-disk file, off-disk file log and sandbox Correspondingly, after receiving the operation request of the off-disk file, before detecting whether the logging process of the off-disk file is running normally, the following steps are added: according to the operation request of the off-disk encrypted file, the off-disk Encrypted files are decrypted; an off-disk file logging process is generated during the decryption process.

[0056] Correspondingly, the off-disk file traceability method provided in this embodiment specifically includes:

[0057] Step 310: When receiving the operation request of the off-disk encrypted file, decrypt the off-disk encrypted ...

Abstract

The embodiment of the invention discloses an off-disk file tracing method, device, terminal and storage medium. The method includes: when receiving an operation request for an off-disk file, detecting whether the off-disk file log recording process is running normally; when the off-disk file log recording process is running normally, starting the off-disk file operation sandbox; Whether the off-disk file operation sandbox is running normally, when the off-disk file operation sandbox is running normally, the off-disk file operation sandbox responds to the operation operation request of the off-disk file; obtains the operation operation of the off-disk file , and write operation information into the off-disk file log running in the off-disk file operation sandbox; when the network environment meets the requirements, send the off-disk log file to the network disk, so that the network disk can obtain the off-disk file operation information.

Description

technical field [0001] Embodiments of the present invention relate to the technical field of network disks, and in particular to a method, device, terminal and storage medium for tracing files off disk. Background technique [0002] With the rapid development of Internet cloud computing technology, network disk service has become a core content of contemporary information services. Users can realize remote storage, reading and sharing of files through the network disk, so the convenience of use and access flexibility of data can be greatly improved. [0003] In the process of digital transformation of enterprise information, enterprise data security is particularly important. The network disk has strict security management for files, and different users have different permissions for the same file. Through different settings for permissions, it can effectively ensure that sensitive information in the network disk files will not be leaked. However, users can distribute netw...
