Toward Court-Admissible Sensor Systems to Fight Domestic Violence

Gender-based violence is an important problem in nowadays society. A huge number of women are killed every year, and those who survive often live in constant danger because of potential retaliation. In an effort to deal with this problem from a technological perspective, the UC3M4Safety task force has developed an innovative solution to detect stress or violence based on data obtained from smart wearable sensors. The goal is to use that information to trigger alarms and to be used as an admissible evidence in a court of law. The goal of this paper is to design a security architecture for the sensor system addressing all relevant security issues according to the European regulation in terms of data privacy and data protection (General Data Protection Regulation). The design tries to preserve the chain of custody of the data in order to facilitate its consideration as admissible evidence in court.
