As the value and importance of softwares are growing up, software theft and piracy become a much larger problem. To tackle this problem, it is highly required to provide an accurate method for detecting software theft and piracy. Especially, while software theft is relatively easy in the case of Android applications (apps), screening illegal apps has not been properly performed in Android markets. In this paper, we propose a method to effectively measure the similarity between Android apps for detecting software theft at the executable file level. Our proposed method extracts method reference frequency and manifest information through static analysis of executable Android apps as the main features for similarity measurement. Each app is represented as an n-dimensional vectors with the features, and then cosine similarity is utilized as the similarity measure. We demonstrate the effectiveness of our proposed method by evaluating its accuracy in comparison with typical source code-based similarity measurement methods. As a result of the experiments for the Android apps whose source file and executable file are available side by side, we found that our similarity degree measured at the executable file level is almost equivalent to the existing well-known similarity degree measured at the source file level.

안드로이드 어플리케이션은 인텐트를 이용하여 다른 어플리케이션의 컴포넌트를 실행시킬 수 있다. 이러한 상호작용이 정상적으로 호출되거나 처리되지 않으면 기대한 컴포넌트가 실행되지 않는 등의 문제점이 발생할 수 있다. 본 논문에서는 이와 같은 어플리케이션간의 상호작용 문제점을 검사하기 위해 어플리케이션들의 소스코드와 매니페스트 파일로부터 컴포넌트 다이어그램과 인텐트 목록을 각각 추출하여 결합된 액티비티 다이어그램을 생성하고 이로부터 테스트 시나리오를 생성하는 기법을 제안한다.

With a wide dissemination of smartphones, the number of native applications developed and sold freely by anyone is growing now. The application market activated by Apple's App Store is spreading more rapidly with Google's Google Play. But due to platform-dependent of native application's attribute, developers are programming at each platform. As a result, development cost is increasing compared to earnings. To solve a dependency problem, people focused on web application developed by web-based language. However, stores at each browser are requiring a web application to follow manifest format. And this causes browser-dependent problem. Those problems can be solved by installing a certain browser, but this can make an application useless on the other browser of a store. Dependency problem can narrow not only user's application variation, but also concentration on some specific store. OWS(Open Web Store) is a standard store that supports various web environments. It overcomes browser or platform dependency problems by interworking applications between stores. Also customers are able to choose a large number of applications. In this paper, related to OWS, I would like to suggest manifest standards and store's reference architecture. An interworking scenario is going to be proposed as well.
