In present circumstances, Coronavirus Disease-2019 (COVID-19) is a very significant health issue affecting human life all over the world. In an Internet of Medical Things (IoMT) environment, the deployed wearable Internet of Things (IoT)-enabled smart devices in a patient's body sense vital information. COVID19-related information is very confidential and private. Thus, the data can be stored into private-blockchain-based distributed cloud storage. For big data analysis, it becomes difficult to decrypt each block residing in the blockchain. Hence, only useful blocks can be searched and then decrypted in order to lessen the computational burden. To deal with this, we discuss a search technique on encrypted COVID-19 data for a blockchain-assisted distributed encrypted database. Finally, blockchain implementation has been also provided to show its effectiveness.
