People IoT surroundings have become valuable information sources that can positively impact individuals and society. A user IoT data can be used for different purposes. For instance, research and improvement of public services. However, individuals lack the governance power to share their IoT data. Data trust is a concept that brings opportunities to address data sharing in IoT. This research reviews the idea of data trust. Then, we review IoT and its unique characteristics that implement data trust a challenge. We further discuss blockchain technology and how it can be used to enable data trust in IoT. Finally, we introduce a blockchain-based solution for data trust in IoT.
