IoT is changing the way for a world, where many of our daily objects will be connected with each other and will interact with their environment in order to collect information and automate certain tasks. IoT requires seamless authentication, data privacy, security, robustness against attacks, easy deployment, and self-maintenance. Protecting data in the internet of things is essential for making the IoT environment secure. In order to secure the data on the internet of things, the blockchain will provide distributed peer to peer networks. Blockchain-based internet of things is making a secure environment in the IoT environment. Data are stored in the form of images in IoT devices that are captured in various locations in the IoT environment for processing. Images are stored as data in the blockchain and it acts as a transaction. This paper expresses the environment of blockchain-based internet of things with image validation. This paper will explain this domain with an example of a criminal’s image identification with image processing techniques to provide better service to the cyber intelligence agency to find criminals easily. The identification of criminals is done by comparing the images of the criminals’ identification. |
