Embodiment Construction
[0122] In order to solve the problem that watermark information is easily tampered with in the existing digital text embedding watermark method, the present invention proposes a digital text watermark embedding and detection method and device.
[0123] The implementation principle of the digital text watermark embedding method provided by the embodiment of the present invention is as follows: in the digital text watermark embedding method provided by the embodiment of the present invention, the server encodes the copyright information of the digital text requested to embed the watermark, wherein the copyright information is used to represent the The attribute information of the sending end of the digital text, split the encoded string into several substrings, and judge whether each character of the digital text needs to be embedded with a watermark according to the chaotic algorithm, that is, calculate the characters that need to be embedded with a watermark in the digital text ...
