在文本特征值的信息隐藏过程中,特征值是一个句子固有的属性,具有随机性.通过分析特征值之间的相关关系,找出其分布变化规律,才能控制其变化,以实现更好的信息隐藏.针对文本信息,首先在VC平台下设计出自动的特征值提取算法,然后利用SPSS统计软件统计分析了文本的特征值.实验结果表明该算法的统计分析给出了有效的特征值数据.
Eigenvalue is a fixed characteristic of a sentence in the extraction for texts and distributes randomly.Through analysis of kinds of eigenvalues' relation and their distribution rules,information hiding can be achieved.As to example text,firstly automatic eigenvalue extraction algorithm based on VC is constructed,then its eigenvalue is analyzed using statistical software SPSS.The numerical experiment result shows that the algorithm can provide effective eigenvalue data.
