A Novel Model of Comprehensive Data Encryption for the Website Using Blockchain

Abstract

The paper proposes a comprehensive data security model for blockchain-based web applications. This model can be used as a general template for Web3 applications. The model consists of two parts: a blockchain core with integrated database encryption modules, replacing Fabric CA; and an application part that also integrates file encryption, database encryption, and digital signatures. The proposed model was tested on a VBCC management website using Hyperledger Fabric. File and database encryption uses AES, and digital signatures use ECDSA. To improve performance, we also replaced the GolevelDB database management system with LevelDB. Experimental results confirm the accuracy and good performance.
