Problems solved by technology

However, when the file to be processed is large, it takes a long time to add the watermark, so it will slow down the opening speed of the file preview page, thereby affecting the actual experience of the user. In severe cases, the setting will also cause an error to be reported on the file preview page. As a result, the file cannot be previewed

Embodiment 1

[0046] figure 1 The flow chart of the method for adding a dynamic watermark provided in Embodiment 1 of the present invention, as shown in the figure, the method for adding a dynamic watermark in this embodiment specifically includes the following steps:

[0047] Step 110, when the file preview action is triggered, obtain the preview record of the user and the historical preview record of the file.

[0048] Due to differences in file preview habits of different users, different users will have different preview pages and preview speeds during the file preview process. Correspondingly, depending on the content recorded in the files, different files may also have different preview pages and preview speeds during the process of being previewed. In order to reduce the workload of adding dynamic watermarks on the network disk at the moment when the file preview is opened, it is necessary to obtain the user's preview record and the historical preview record of the file when the fil...

Embodiment 2

[0062] figure 2 It is a schematic flowchart of the method for adding a dynamic watermark provided by Embodiment 2 of the present invention. This embodiment is optimized on the basis of the above embodiments. In this embodiment, after the file page with the watermark is converted to the preview state, the following steps are added: obtain the preview progress of the file, and when the current preview progress is greater than the expected Add a watermark to the preset watermarked supplemental pages when the progress threshold is set.

[0063] Correspondingly, the dynamic watermark adding method provided in this embodiment specifically includes:

[0064] Step 210, when the file preview action is triggered, obtain the user's preview record and the historical preview record of the file.

[0065] Step 220: Calculate the number of watermarked pages of the file according to the user's preview record and the file's historical preview record.

[0066] Step 230: Add a watermark to th...

Embodiment 3

[0076] image 3 It is a schematic flowchart of the dynamic watermark adding method provided by Embodiment 3 of the present invention. This embodiment is optimized on the basis of the above embodiments. In this embodiment, after the file page with the watermark is converted to the preview state, the following steps are added: obtain the user's file preview speed, and When the speed is less than the preset speed threshold, obtain the user's permission information; when the user does not have the file download permission, convert the file page with the watermark and in the non-preview state to the processing state, and add complex information to the file page in the processing state Watermark and convert file pages with complex watermarks to preview state again.

[0077] Correspondingly, the dynamic watermark adding method provided in this embodiment specifically includes:

[0078] Step 310, when the file preview action is triggered, obtain the preview record of the user and th...

Abstract

The invention provides a dynamic watermark adding method, device, network disk and storage medium. Wherein the method includes: when the file preview action is triggered, obtaining the user's preview record and the historical preview record of the file; according to the user's preview record and the historical preview record of the file, calculating the number of pages to add the watermark to the file; according to the Watermark Add Pages, add a watermark to a document, and convert watermarked document pages to a preview state. The invention creates a method, device, network disk and storage medium for adding a dynamic watermark, which can reduce the workload of adding a dynamic watermark at the moment when the file preview is opened, thereby improving the user's file preview experience.

Description

technical field [0001] The invention belongs to the technical field of electronic information, and in particular relates to a dynamic watermark adding method, device, network disk and storage medium. Background technique [0002] When online previewing files inside the network disk, in order to ensure the security of the files, it is necessary to add a watermark to the inside of the files. The so-called watermark is a specific digital signal embedded in a digital product. By adding a watermark, the integrity of the digital product can be protected without affecting the use value of the original content, so as to prevent others from misappropriating the digital product. At the same time, by adding watermarks, information such as content creators and product owners can be recorded in digital products, so it can also facilitate traceability. [0003] In the prior art, the watermark is usually added to the file in advance, and the file containing the watermark can be directly l...
