Detecting Software Theft with API Call Sequence Sets David Schuler Valentin DallmeierSaarland UniversityDepartment of Computer ScienceSaarbr¨u cken,Germany{schuler,dallmeier}@st.cs.uni-sb.deAbstractSoftware birthmarking uses a set of unique character-istics every program has upon creation to justify own-ership claims of stolen software.This paper presents a novel birthmarking technique based on the interac-tion of a program with the standard API.We have used this technique to succesfully distinguish4differ-ent implementations of PNG image processing.1IntroductionIn the last few years we have witnessed a huge in-crease in the amount of open source currently hosts over115.000projects,a large portion of which is licensed under the GNU Public License(GPL).This type of license allows users to pass on the program without charge,but requires new projects using it to also be licensed under GPL.Unfortunately for the spirit of open source,not all individuals or companies obey to these restrictions.A popular example of the recent past is the XCP copy protection software present on many audio discs. It contains and uses several GPL projects(LAME, DRMS and others),but is not distributed under the terms of the GPL.There are many more examples of companies that illegally use GPL projects to save de-velopment resources.This is a severe disadvantage for companies that either don’t use such projects or also put their products under the GPL.In order to address the problem of software theft, researchers have proposed the use of birthmarks for the prove of ownership.Birthmarking relies on a set of characterstics a program originally possessed.Two programs that have similar or identical birthmarks are very likely to be the same.This paper proposes a new dynamic birthmark. The birthmark is based on the observation that the way a program uses standard libraries(e.g.the JAVA API)is a unique characteristic of every program.The remainder of this paper gives details about our birth-mark,presents a small experiment to evaluate it’s ef-fectiveness,and discusses the results.Figure1:Example Interaction with JAVA API.2Birthmark ExtractionSince the last release of the java development kit,the standard API consists of more than4600classes.As virtually every JAVA program uses classes of the API during its execution,API interaction is a good candi-date for a birthmark.This section explains the way we capture a program’s API interaction and the de-termination of the birthmark.Figure1shows a small example where a user im-plementation of a depthfirst search(DFSearch)uses a Stack provided by the API.To characterize the usage of the API,we use the sequence of calls that originate in a user class and invoke a method that is part of the API.We call this the sequence of API method calls. For our example,the sequence of API method calls is push(Node),pop()and top().For realistic program runs,a trace of the sequence of API method calls quickly reaches several gigabytes in size and becomes difficult to handle.Rather than using the whole trace,we extract sets of call sequences from it.A call sequence set is obtained by sliding a window with afixed size over the trace and remem-bering all window contents observed.Dallmeier et al. (2005)provide further details.Using call sequence sets,we can compare two pro-grams P and Q in the following way.We trace execu-tions of both P and Q and calculate the sequence sets S P and S Q.If P and Q are the same program or at least closely related,we expect a large number of se-JAI JIMI JIU SIXLEGS JAI0.940.010.020.02JIMI0.01 1.000.130.00JIU0.020.13 1.000.04SIXLEGS0.020.000.04 1.00Table1:Credibility results.quences to occur both in S P and S Q.The birthmark value B(S P,S Q)measures the fraction of common call sequences in the union of S P and S Q:B(S P,S Q)=#(S P∩S Q)#(S P∪S Q)(1)A birthmark value close to1indicates that P and Q have very similar API interaction and thus we suspect P and Q to be the same program.3Evaluation of CredibilityWe require a birthmark to be credible:Two indepen-dently written programs P and Q that may accom-plish the same task must have different birthmarks. In other words:If P and Q have the same birthmark, then P=Q should be true in almost all cases.In order to evaluate the credibility of our birthmark technique,we have conducted an experiment with4 libraries for reading PNG images.For each library we collected the API call sequence sets from reading a test suite of110PNG images.Table1shows the birthmark values for comparing each run of a library against all others.When comparing a library with itself(e.g. JIMI with JIMI),we compare the call sequence sets extracted from two runs using the same test suite as input.Our results show that using API call sequences is a credible birthmark:All birthmark values for execu-tions of different libraries are close to zero,indicating a strong difference in API interaction for all libraries although they implement the same task.The results for comparing two runs of the same library are located on the main diagonal.Except for JAI,all values are 1.00,indicating that the call sequence sets for both runs were the same.The slight difference in the call sequence sets for JAI are due to some GUI threads running in the background.4Related WorkIn previous work by Dallmeier et al.(2005)we have used call sequences to compare passing and failing runs of a program.Call sequences are collected on a per-class basis,and compared across runs tofind the class that is most likely to contain the defect.Tamada and Nakamura(2003)describe thefirst practical application of birthmarks to identify the theft of programs.They propose a set of static birth-marks for classes,such as the constant values used to initialize thefields of a class.A preliminary evalua-tion reports that the proposed birthmarks identify a class within a program with high precision,but can easily be confused by several obfuscation techniques.Tamada and Okamoto(2004)introduce a definition of dynamic birthmarks and propose two such birth-marks based on the trace of system calls for Windows programs.They claim that these birthmarks are rea-sonably robust against obfuscator attacks,but give no experimental evidence.5Conclusions and Future WorkWe have presented a new dynamic birthmark tech-nique based on the extraction of API call sequence sets from program runs.In a preliminary experiment, our technique successfully distinguished4different li-braries for PNG image processing.These results are promising and justify further evaluation of our tech-nique.Among other things,our future work will con-centrate on the following topics:Birthmark Refinement A possible improvement of the birthmark may be to ignore calls to commonly used API classes like String to avoid pollution of the call sequence sets.Evaluation of Resilience An effective birthmark must be resilient to semantic preserving transforma-tions like obfuscation.We plan to evaluate the re-silience of our technique against several available ob-fuscation techniques.Refactoring Support Our technique also allows to identify classes with similar or identical runtime be-havior,which may be helpful in refactoring an appli-cation.For future and related work regarding birthmarking, seehttp://www.st.cs.uni-sb.de/birthmarking/ Acknowledgements Christian Lindig provided valuable insights during birthmark design and eval-uation.ReferencesValentin Dallmeier,Christian Lindig,and Andreas Zeller.Lightweight defect localization for Java.In Andrew Black,editor,European Conference on Object-Oriented Prog.(ECOOP),pages528–550,2005.Haruaki Tamada and Masahide Nakamura.Detecting the theft of programs using birthmarks.Inf.Science Techni-cal Report NAIST-IS-TR2003014,Graduate School of Information Science,November2003.Haruaki Tamada and Keiji Okamoto.Dynamic software birthmarks to detect the theft of windows applications.In Proc.Int.Symposium on Future Software Technology 2004,2004.Xi’an,China.。
