The establishment of IoT devices in all areas of public and private life raises, besides many new possibilities, also a number of new privacy issues. In particular, the establishment of almost invisible audiovisual sensors, like in smart speakers or smart cars, affects not only the user who purchases these IoT devices, but all those who are within the recording radius of them. At present, it is almost impossible for such uninvolved users to recognize all the surrounding recording IoT devices and their data processing, let alone object to this recording. This means, there currently is exclusively foreign control of the personal data of bystanders. Therefore we present our work in progress, to get towards transparency about the capturing and processing of audiovisual data by surrounding IoT devices one step closer. In this we assume that in the future such devices will have to identify themselves and their respective privacy policies. We have implemented a first prototype of our concept and show the need of such transparency solution by pre-evaluating it.
