防伪电子票打印扫描过程中的数字水印失真和还原技术
Digital watermark distortion and reduction technology in the process of anti-counterfeiting electronic ticket printing and scanning
摘要
Abstract
The distortion and reduction technology of digital watermark are the important research directions of current infor⁃mation secrecy. The basic framework,classification features,typical algorithms and performance evaluation of digital watermark system are illustrated by introducing the overview of printing,scanning and digital watermark technology. The influence of basic model,scanning and printing process of continuous tone method on image is introduced by analyzing the printing and scanning processes of digital image. The pixel distortion and geometry distortion are analyzed in detailed,and the correction method is proposed. The printing and scanning digital watermark system based on DCT was designed in the aspects of digital watermark embedding and extraction. The related robustness experiment was studied,and it was found that the designed printing and scan⁃ning digital watermark system has good anti⁃counterfeiting and proof⁃tamper performances,and the advantages of faster read and embedding,and lower bit error rate than those of other algorithms.关键词
