A software birthmark refers to the inherent characteristics of a program that can be used to identify the program. In this paper, a method for detecting the theft of Java programs through a static software birthmark is proposed that is based on the control flow information. The control flow information shows the structural characteristics and the possible(More)
A software birthmark is a unique characteristic of a program that can be used as a software theft detection. In this paper we suggest and empirically evaluate a static birthmark of binary executables based on API call structure. The program properties employed in this birthmark are functions and standard API calls when the functions are executed. The API(More)
Software birthmark is the inherent program characteristics that can identify a program. In this paper, we propose a static API trace birthmark to detect Java theft. Because the API traces can reflect the behavior of a program, our birthmark is more resilient than the existing static birthmarks. Because the API traces are extracted by static analysis, they(More)
A software birthmark means inherent characteristics that can be used to identify a program. In this paper, we propose a birthmark technique based on object traces of Java programs. Java is an object-oriented programming language that provides various predefined class libraries that help programmers to produce software easily. In order to utilize Java class(More)
A software birthmark means the inherent characteristics of a program that can be used to identify the program. A comparison of such birthmarks facilitates the detection of software theft. In this paper, we propose a static Java birthmark based on a set of stack patterns, which reflect the characteristic of Java applications. A stack pattern denotes a(More)
A software birthmark is an inherent characteristic of a program that can be used to identify that program. By comparing the birthmarks of two programs, it is possible to infer if one program is a copy of another. In this paper, we propose a static birthmark based on the control flow edges in Java programs. Control flow edges can represent possible behaviors(More)
A software birthmark is an inherent program characteristic that can identify a program. In this paper, we propose a static instruction trace birthmark to detect code theft of Java methods. Because the static instruction traces can reflect the algorithmic structure of a program, our birthmark can be used to detect algorithm theft which existing static(More)
A software birthmark means the inherent characteristics of a program that can be used to identify the program. By means of comparing the birthmarks of programs, the fact of the software theft can be detected. In this paper, a static Java birthmark is proposed by utilizing a set of behaviors as the characteristics of the Java applications. A behavior denotes(More)
