Non-Repudiation Storage and Access Control Scheme of Insurance Data Based on Blockchain in IPFS
The insurance business plays a quite significant role in people's lives, but in the process of claim settlement, there are still various frauds such that the insurance companies' refusal to compensate or customers' malicious fraud to obtain compensation. Therefore, it is very importan...
