Title:
METHOD AND APPARATUS FOR ADDING WATERMARK IN DATA, AND RELATED DEVICE
Document Type and Number:
WIPO Patent Application WO/2023/279837
Kind Code:
A1
Abstract:
The present application provides a method for adding a watermark in data, specifically comprising: obtaining a plurality of pieces of data to be processed; further obtaining a plurality of groups corresponding to the plurality of pieces of data to be processed, the plurality of groups comprising a target group; and then, by taking the target group as a granularity, adding a watermark to data to be processed in the target group. By taking a group as a granularity, a watermark is added to a plurality of pieces of data to be processed, so that although the data to be processed in the group is modified due to the addition of the watermark, a change range of the data falls within a range of a small amount of data to be processed comprised in the target group, rather than within a range of all data to be processed, thereby alleviating the problem of serious distortion of the data after the addition of the watermark. When data to be processed having similar semantics is divided into a same group, there is a small semantic change in the data to be processed in the target group before and after addition of a watermark. In addition, the present application further provides an apparatus for adding the watermark in the data, and a related device.
