程序的语义体现在程序对数据的处理过程中，在数据处理的过程中数据的调用序列以及值变化的序列和程序的语义是紧密相关的。为此，分别对程序中的常量和变量进行分析得到基于程序数据属性的各个子特征，由各个子特征共同构成基于程序数据属性的联合软件特征。计算每个子特征的相似度，以各个子特征相似度的平均值表征联合软件特征的相似度。理论和实验结果均表明：该特征具有较高的可信性和鲁棒性。

The semantics of a program is reflected in data processing by the program,and in the process of data processing,the calling se-quence and value variation sequence of data are closely related to the semantics of the program.For this reason,we analyse the constants and variables in program separately and obtain each sub-birthmark which is based on program data attribute.The associated software birthmark based on program data attributes is constituted by those sub-birthmarks.The similarity of each sub-birthmark is calculated,the average value of the similarity of each sub-birthmark is employed to represent the similarity of associated software birthmark.Theory and experimental result all show that this birthmark has high credibility and robustness.
