Abstract

A method, apparatus, and system for adding a watermark to a secret file, and a medium, relating to the field of watermark addition. The method comprises the following steps: obtaining content information on a display screen of a terminal, the content information comprising a document and a webpage (S101); determining whether the document and the webpage comprise secret information (S102); and if yes, adding watermarks to secret areas of the document and the webpage (S103), the watermarks being generated by a watermark generation server. The method, apparatus, and system for adding a watermark to a secret file, and the medium can effectively identify whether a document and a webpage on a display screen are secret, and then targetedly add watermarks to secret areas, so as to not only ensure the security of secret information and implement anti-counterfeiting tracing and copyright protection, but also enable a user to comfortably read content outside secret areas, thereby improving user experience.

Description

technical field [0001] The invention relates to the field of adding watermarks, in particular to a method, device, medium and system for adding watermarks to confidential documents. 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 a text carrier, and this technology does not affect the use value of the original carrier.
