Smart home devices are increasingly used to automate daily tasks and provide enhanced comfort and convenience. However, as these devices become universal, their security risks also increase. These risks are caused by a lack of implementation of secure safety methods embedded within these devices and the nature of the data generated by these devices that could be used for malicious activities. In this paper, we propose an innovative robust approach to improve the security of data generated or collected by smart home devices. Our proposed method combines Blockchain with Vazka Authentication. First, our solution involves creating a decentralized system for storing devices collected or generated data using blockchain. Then, we introduce our new authentication mechanism, called Vazka, to limit unauthorized access to smart home devices data. It consists of dynamically generating a password based on the collected data signature. We analyze a particular case study that consists in applying our proposed solution to a smart home security camera’s system. Our proposed solution has the potential to significantly enhance the security of video footage generated and collected by the smart home security camera. Overall, our proposed solution makes it more difficult for malicious actors to gain unauthorized access and/or tamper smart home devices collected data.
