Android devices are increasingly used in corporate settings. Although openness and cost-effectiveness are key factors to opt for the platform, its level of data protection is often inadequate for corporate use. This paper presents a strategy for secure credential and data storage in Android. It is supplemented by a context-aware mechanism that restricts data availability according to predefined policies. Our approach protects stored data better than iOS in case of device theft. Contrary to other Android-based solutions, we do not depend on device brand, hardware specs, price range or platform version. No modifications to the operating system are required. The proposed concepts are validated by a contextaware file management prototype.
