Exercise and Diet Architecture Design Based on Blockchain Network

In order to solve the problems occurring in the current data collection apps, the methodologies of blockchain including decentralized data transmission, transaction security, data privacy, and permanent data storage are adopted in the Exercise and Diet Architecture (EDA). In EDA, personal data is stored and transferred under the secure mechanism in the blockchain network. In which, all data are protected through secure hash algorithm and digital signature, which could be decrypt only through the corresponding key. Moreover, all transactions are transmitted in privacy because of the peer to peer transmission method. Thus, EDA is designed for storing data in a fully privacy and security environment.
