I presented a poster on “DIY-ethics of sensor networks” during “the Sense of Contact” on 13 December 2017 at the Beurs van Berlage in Amsterdam, The Netherlands. Increasingly, sensors are integrated in the Internet-of-Things, allowing for the aggregation of big data on the functioning of household electronics including smart meters, fridges, and televisions. Likewise, medical sensors and lifestyle sensors integrated in smart phones contribute to aggregation of health data. These sensors offer benefits to the users, but also raise challenges to privacy, data protection, and security. Three types of solutions are envisaged: technical, legal, and social fixes. I presented a framework for Do-It-Yourself Ethics where stakeholders combine solutions in a common responsibility for ethically sound development of sensor networks in daily life. Info: poster.
