Security Perspectives for Collaborative Data Acquisition in the Internet of Things

The Internet of Things (IoT) is an increasingly important topic, bringing together many different fields of computer science. Nevertheless, beside the advantages (IoT) has to offer, many challenges exist, not at least in terms of security and privacy. In addition, the large number of heterogeneous devices in (IoT) produces a vast amount of data, and therefore efficient mechanisms are required that are capable of handling the data, analyze them and produce meaningful results. In this paper, we discuss the challenges that have to be addressed, when data analytics are applied in the context of the (IoT). For this, we propose a data acquisition architecture, named CoDA, that focuses on bringing together heterogeneous things to create distributed global data models. For each layer of the proposed architecture we discuss the upcoming challenges from the security perspective.
