Research On Android Applications Intellectual Property Protection

With the development of mobile Internet,the mobile intelligent devices are rapidly popularized.The Android system is the most mobile operating system in the global market share,and because its open source and applications are easy to get,which makes the attacker through the reverse and repackaging technology is very easy to plagiarism Android applications.Which not only leads to a large number of malicious applications in the Android application store,and serious violates intellectual property of applications developers.In view of the above questions,the Android application signature and Android application software watermarking are two effective solutions.The signature mechanism provided by Android system can't prevent unauthorized third-party recomposing published app,and it is also difficult to verity the original developer's signature of the republished app.To address the above problems,a Android applications authorization scheme is proposed based on RSATS-2 transitive signature.In view of the fact that the exists Android application watermarking schemes are difficult to verify the copyright of the developer when the watermarking information is damaged,this paper proposes a new recoverable application watermarking scheme based on Chinese Remainder Theorem.In this paper,the Android Apps authorization scheme constructed by RSATS-2 is an improvement of the existing Android signature schemes.And using the transitive signature applies to binary transfer relationship signature features to achieve applications authorization and verify the original developer's copyright.According to a claimer(app developer)provides parameters and calculated synthetic signatures,a verifier is able to verify the legitimacy of statement provided the claimer with the published application of redevelopment of the third party,which achieves application developer's copyright protection.Taking into account a malicious third-party may delete the authorization file,the authorization file is scatted hided in the Android application's images.The analysis shows that the proposed scheme is feasible and meet the security requirements of Android app signature.The proposed recoverable application watermarking scheme with the China Remainder Theorem,firstly,constructs a recoverable watermarking algorithm based on Chinese Remainder Theorem,and then,generates watermarking information by the recoverable watermarking algorithm,lastly,encodes the watermarking information to a base map and compresses the embedding watermarking information.Experiment analysis shows,the proposed scheme is able to effectively recover completed watermarking for the partially destroyed watermarking,and it has smaller performance performance overhead to users.To address Android Apps copyright protection problems,this work analysis existing solutions,and proposes a more practical Android APP authorization scheme and a more effective Android APP watermarking scheme.The research is helpful for protecting intellectual property of Android APP developers,and prevents malicious software plagiarism,to a certain extent,it also is able to prevent the proliferation of Android malwares.Which is good for constructing a security Android APP development environment,and ensuring rights and interests of Android application developers.
