摘要
根据字符(串)信息在数字水印加载和检测当中鲁棒性适应较好的这一特性,利用载体字符计算出一系列伪随机代码,进而产生能够及时纠正错误的可适应性文本数字水印。分析表明,通过这一设计的实验产生的伪随机代码在随机性上较为灵活,仿真实验数据也进一步印证了改变字符或字符串的拓扑结构保持水印扩频技术的优势,并较好地提高了抗攻击性能。
According to the character （string） robust digital watermarking information in loading and detection of adapt to the cha-racteristics of good character, the calculation of a series of pseudo random code, which can correct the adaptability of text digital watermarking error. Analysis shows that, pseudo random code generated by the design of the experiment is very flexible in random, experimental data and further verify the watermark spread spectrum technology change of topology character or string to keep ad- vantage, and improves the anti-attack capability.
