Application of Identity Resolution System under Industrial Internet: Taking Cold Chain Traceability as an Example

The industrial Internet is an industrial ecosystem formed by the deep integration of the Internet and industrial systems. The identity resolution system, which serves as the “identity card of the digital world”, has become the basis for supporting the interconnection of information and data inside the industrial Internet. However, the goal of timely information sharing and efficient cooperation among different identity resolution systems has not been met at the current stage. Taking cold chain traceability as a practical example, shortcomings of cold chain information interaction are analyzed and a corresponding identity resolution system is proposed in this paper. The related identity functions for cold chain traceability are explained through the operating technologies and mechanism of each layer including identity registration and resolution. The detailed application is carried out in a specific case study of cold chain traceability, which proved that the adoption of the identity resolution system makes the convey and sharing of information about virus inspection and transportation records more efficient.
