Ubiquitous computing has fundamentally redefined many existing business models. The collected sensor data has great potential, which is being recognized by more and more industries, including car insurance companies with Usage-Based Insurance (UBI). However, most of these business models are very privacy-invasive and must be constructed with care. For a data processor, the integrity of the data is particularly important. With kUBI, we present a framework that takes into account the interests of the providers as well as the privacy of the users, using the example of Android. It is fully integrated into the Android system architecture. It uses hybrid data processing in both stakeholder domains. Protected enclaves, whose function can be transparently traced by a user at any time, protect company secrets in the hostile environment, i.e. a user’s smartphone. The framework is theoretically outlined and its integration into Android is shown. An evaluation shows that the user in the exemplary use case UBI can be protected by kUBI.
