AI Technical Summary

Technical Problem

How to ensure the trustworthiness and traceability of data transaction processes in the data plane or data collection processes in the data pipeline in a communication system, especially when dealing with massive amounts of sensing and positioning data, to avoid increased deployment costs and impact on processing efficiency for operators, while also considering the trust domain characteristics of the communication network.

Method used

The introduction of a first ledger and a first signature is used to record the data transaction process or data collection process. Through the verification of the ledger and signature, the details of data transactions can be traced and participants can be prevented from denying their rights, ensuring the credibility and traceability of the process.

Benefits of technology

It achieves trustworthiness and traceability in the data transaction and collection process, prevents participants from denying their rights, reduces operator deployment costs and maintains processing efficiency, and is suitable for the trusted domain of the core network.
