Insurance Block: A Blockchain Credit Transaction Authentication Scheme Based on Homomorphic Encryption

Abstract

The data transaction in insurance has problems in terms of low security, high management cost and difficulty in supervision. This paper proposes a trustable blockchain based transaction authentication scheme based on homomorphic encryption. By considering the features of distributed authority management in insurance business, a shared insurance account book is realized as well as the data consensus, smart contracts and special chained storage structures. The experimental results show that the proposed scheme has high security and effectiveness.
