Digital watermark algorithm based on text document protection
ActiveCN107688731AStrengthen copyright protectionImprove robustnessImage analysisImage data processing detailsComputer graphics (images)Documentation
The invention discloses a digital watermark algorithm based on text document protection. Implementation of watermark information in a text document consists of watermark embedding and watermark extracting; a watermark embedding treatment process comprises carrier text image pretreatment, ciphertext ID coding, pseudo-random periodic sequence watermark generation and carrier image fusion; and the watermark extracting treatment process comprises image reinforced treatment, extraction of a pseudo-random sequence watermark texture map and decoding of watermark information. For solving the technicalproblem that an existing digital watermark algorithm is poor in robustness, required ID information can be embedded in a text document by the algorithm, and even if a watermarked text is copied, photographed and sheared and the geometric structure of the watermarked text is damaged, watermark information concealed in the watermarked text can still be detected. The digital watermark algorithm based on text document protection can be widely applied to protection and tracing of documents with secret, document copyright protection, web page copyright protection, image mark protection of some commercial products and the like.
