Improvement of the Dynamic Software Birthmark Process by Reducing the Time of the Extraction

The dynamic software birthmark methods are the methods to detect the stolen programs based on the runtime behavior of the target programs. For this, the dynamic birthmark methods extract the characteristics of programs themselves by running the target programs. Then, the extracted characteristics are compared and calculated the similarities between two characteristics. If the similarity is greater than the given threshold, either of programs is suspected the stolen program from the other. Based on the process, many researchers proposed various dynamic software birthmark methods focused on different aspect of the runtime behaviors. However, the problem is that above detection procedure consumes much time cost. The main cause is the extraction requires the suitable inputs, and the cost for preparing inputs is quite high. Because, the preparation of inputs need the understanding the target programs, and the dynamic birthmarks generally require several inputs for reliable results.
