Abstract
The blockchain technology based on digital signature provides a non-repudiation and non-tampering mechanism for digital storage and communication, which has been applied in various sub-fields of Information technology. The biggest problem of the current method is that the public-private key pair that identifies an entity's digital identity cannot be effectively mapped to its physical identity, which reduces the reliability of the signature. We propose Offline Blockchain embedded into material objects to achieve strong correlation between physical and digital identities, which ensures the full-process credibility and traceability for process tracing, especially for supply chain management and logistics.
