摘要
介绍了文本文件数字水印的白空格编码方法 ,着重讨论了使用标准空格进行水印编码即附加空格编码的实现方法。为了提高算法性能 ,在程序实现中提出了一些适当的处理方法并加以实现。对程序的性能进行了分析 ,其结果令人满意。
Text documents have plenty of white space between words and lines and the amount of this white space can be subtly modified to hide the tagging information that could identify the owner.The main advantage of using the empty sections to encode data is that the text does not need to be changed.A brief introduction is given to the white space coding for text document watermarking and then some schemes are proposed in program implementation of extra space coding in order to improve the algorithme.An analysis of its performance was made with satisfactory results.
