| Abstract | Smart cities utilize Internet of Things (IoT) devices including connected sensors to collect data that may be used to enhance public services, infrastructure, and service delivery. The full promise of smart cities cannot be realized, however, until serious security concerns are handled. The security of any given communication system is heavily dependent on its access controls. To alleviate the strain of access control on low-capacity devices, delegated authorization mechanisms are crucial in communicating the challenges of IoT devices. New user-centric authorization procedures that guarantee user privacy without compromising scalability or efficiency are necessary before IoT devices can be used in smart cities. Blockchain could serve as a technology that enables many different applications within the context of smart cities. Rapid data collection from a plethora of wireless sensors paves the way for big data analytics to quickly take in the foundational visuals required for smart city resources, supply, and infrastructure management. Blockchain and big data are two of the most exciting new technologies that can be used effectively with their integration. Implementing the access control solution for exchange the of data among IoT devices in smart cities is a challenging task. We introduce a novel architecture for managing access to Bigdata using blockchain technology, which could be used in smart cities. Our proposed access control system will allow a resource owner to securely delegate authorization to other parties beyond the smart city's trust boundary. The article describes the architecture and implementation of the proposed blockchain and big data system, as well as its access control and security features. Our testing on private Ethereum has shown that our solution is straightforward to implement in low-latency environments. This proves our proposed solution's applicability to real-world IoT scenarios in the smart city environment. |
