Abstract

The invention discloses a watermarking information generation method and apparatus. The method includes determining a file selected by a user and acquiring the watermarking information associated with the file; adding the watermarking information to the preset layer according to the setting manner; and overlapping the layer and the file browsing interface. In this way, the watermarking information is added into the layer without changing the file structure, so that the risk of destroying the file structure is eliminated, the robustness is high, and the operation complexity of directly adding the watermarking information into the file is reduced.

Description

technical field [0001] The invention relates to the field of digital watermarks, in particular to a method and device for generating watermark information. Background technique [0002] With the development and progress of information technology, in order to protect the property rights of digital media files, digital watermarking technology came into being and developed rapidly. Under the existing technology, digital watermarking technology is a technology that directly embeds watermark information into the text carrier. This technology does not affect the use value of the original carrier, and it is not easy to be noticed or noticed. [0003] The existence of watermark information should be based on the principle of not destroying the appreciation value and use value of the original data. However, the digital watermarking technology under the existing technology is based on adding watermark information to the file, and there is a risk of destroying the original file struct...
