As Android apps are vulnerable to repackaging attacks, in order to protect these app, a code that runs a tamper detection function is inserted and obfuscated to protect the inserted function while or after building the app. However, with the use of currently released app analysis tools, many tamper detection methods are rendered ineffective. Therefore, it can be used for repackaging attack. To protect against these weaknesses, in this paper we propose the APK Attester scheme that detects app tampering on the platform in order to provide a secure app running environment for users in defense against repackaging attack.
