Abstract The Internet of Things is the next step in the evolution of communication and business(IoT). Real-world objects can create, receive, and exchange data in a seamless manner thanks to the Internet of Things. Several Internet of Things apps aims to automate processes and enable inanimate physical devices to work without human involvement. Existing and future IoT systems offer a lot of potential in terms of improving user comfort, efficiency, and automation. To integrate such a world in an ever-increasing way, high levels of security, privacy, authentication, and attack recovery are required. In this paper, the IoT data and logs are processed with a special Keyword Based Detection System (KBDS) based on the known data & log pattern and stored data attributes, and detect whether the data is shareable or not to the external world based on the sensitivity. Every data flow is noted and managed by the user in the User-Console. If the data is not shareable it will Alert-To-User (ATU). Then the data is getting stored in the InterPlanetary File System (IPFS), the IPFS hash related to the data & logs will be stored in Blockchain. Using Smart contract the user can decide to share which data to respective third-party.
