A car insurance claim processing prototype using smart contracts and zero-knowledge proofs

Abstract

Ensuring the confidentiality and accuracy of owner information is critical in car insurance claims. However, the current traditional auto insurance claims system is inefficient and prone to data leaks, leading to service confusion and inaccurate data. The primary focus is on enhancing the privacy and security of insurance information and car owner data. This paper employs blockchain, smart contracts, and zero-knowledge proof technologies to address privacy concerns and introduces an innovative car insurance claim system. The system transforms authorization and claims processes, incorporating private and public smart contracts for issuing and canceling auto insurance, as well as authorizing and validating claims. Using ZoKrates optimizes data storage and computation on the blockchain while preserving maximum privacy for sensitive information. Experimental results affirm the effectiveness of the scheme in terms of security and performance.
