| Title | Towards Smart Blockchain-Based System for Privacy and Security in a Smart City environment |
| Year | 2020 |

| Abstract | Nowadays, the digitalization of urban environments is redefining the public and private sectors. Moreover, Internet of Things (IoT) platforms, cloud computing infrastructure and smart devices are exchanging tremendous amount of data. This harmonious integration of the cyber capabilities of the corresponding devices with the physical world generates new opportunities in many areas; however it raises a lot of security and privacy challenges due to the diversity of sources and stakeholders, the centralized data management and the resulting lack of trust and governance. Hence, we introduce "SmartPrivChain" a Smart Blockchain Based System for preserving privacy and security in a smart city environment. The proposed scheme is different from the existing approaches on many points. The data privacy is preserved by combining data access control and data usage auditing measures based on smart contracts. In addition, the proposed solution is compliant with the main privacy laws and regulations especially the obligations of the European Union General Data Protection Regulation (GDPR). Lastly, we propose an enhanced Proof of Reputation (PoR) consensus scheme using a multidimensional Trust model. |
