Abstract
We introduce Kynoid, a real-time monitoring and enforcement framework for Android. Kynoid is based on user-defined security policies which are defined for data-items. This allows users to define temporal, spatial, and destination constraints which have to hold for single items. We introduce an innovative approach to allow for the real-time tracking and enforcement of such policies. In this way, Kynoid is the first extension for Android which enables the enforcement of security policies of data-items stored in shared resources. We outline Kynoid's architecture, present its operation and discuss it in terms of applicability, and performance. By providing a proof-of-concept implementation we further show the feasibility of our framework.

Summary
The distribution of Smartphones to employees becomes more and more interesting for companies They enable unified and simplified communication as well as permanent reachability. These companies tend to weaken their traditional security requirements by weakening guidelines and restrictions on these devices to avoid that users replace their business Smartphone and use other means of communication for private purposes. Modern platforms have seen a tremendous increase in innovative applications. They provide easy access to web and cloud services and support the user in their daily activities. This trend is enforced by simple and handy APIs which inspire private application developers. Application markets have become very popular from a developer as well as from a consumer perspective
