The Design And Implementation Of Automatic Application Information Extracting System In Mobile Internet Application Store

With the gradual improvement of iOS, Android and other mobile terminal system, mobile application developers become more, mobile internet applications store develop more rapidly. However, security issues of the mobile intelligent terminal have become increasingly highlights. Mobile internet application stores are too many to effectively monitor and make safety testing to the applications in these stores. To monitor and test the application safety, we need design and implement application software information automated collection system for mobile internet applications store, which can collect application information of application stores periodically and automatically and timely download updated applications. This system can provide massive application information and application software to support the application security testing platform.For the above, this paper first analyzes the needs for mobile Internet applications store information collection system, and outlines the information collection related technology research status, and elaborates the disassembly and network packet capture technology.Because of the closed and special application download mechanism of Google Play and App Store, this paper study this mechanism of official applications store which have few internal studies, and lays the theoretical foundation of implementing the application local downloader of both stores.Based on needs analysis, this paper make outline design of the system, design oriented web crawler according the site structure of different applications store, solve dynamic web page crawling automatic login and other key technologies, and design application page information extraction system. And then research and design the Google Play, App Store application download mechanism, and design multi-threaded applications downloader to improve the rate of download application.Based on the outline design of the system, this paper make the detailed system design, and achieve the application of information collection system and application download system with Java programming.Finally, this paper deploys the system running environment and runs the system, then summarizes and analyzes the application extraction and download results of system. The system running results show that the system can meet the need and achieve the intended goals.
