The main idea is that randomly select two disjoint subsets of equal size out of instruction set and this selection is the watermark which is superimposed by changing the elements of one subset by adding a positive integer factor
在程序的指令集中隨機抽取兩個不相交的基數相等的子集，對特定子集的選取就是要嵌入的水印。改變程序使對應于某個子集的所有指令的出現次數都增加一個常數。 -
The thesis mainly deals with the third part of across : " sompi " cepstrum methods. the principle and system structure of across a re first introduced. the propagation of wave in media is simply studied and its transfer function in frequency domain is modeled as superimposed damped exponential sinusoids, each damped exponential sinusoid is called as a wave element and its exponential index part consists of two factors : group velocity travel time and decayed factor
為此，首先介紹了across的原理與組成和通過簡單地討論地震波在介質中的傳播情況建立起介質的傳遞函數模型，指出：在一個狹窄的頻率窗口裡，介質的傳遞函數可以用有限個阻尼正弦項的疊加的形式表示，每個阻尼正弦項代表一個波成分，其指數部分包括兩個因子：波成分在介質中的傳播時間和衰減因子。
