Personal healthcare has become the most important part of present human life due to the COVID-19 pandemic. The awareness of one’s health is made easily available by adopting IoT wearable devices like Fitbit, smart watches, oximeters, etc. All these devices store sensitive information like a heartbeat, BP, distance traveled, calories burnt, stress levels, location details, etc., and are stored in third-party data servers. These servers are vulnerable to illegitimate users and also have a single point of failure. The personal data of the individuals should be protected along with its integrity. At the same time, the data stored in the servers should be decentralized to overcome the problem of a single point of attack. The objective of this article is to provide a framework that uses SHA-56 for generating the hash code and Blockchain technology to store the data. Thus, providing privacy, security, and integrity for the data.

Keywords: Blockchain, Fitbit, Fitbit data, Encryption, Hashing, IoT, Mining, Privacy, Security, Wearable devices.
