AI Technical Summary

Technical Problem

In existing technologies, how data owners store data and how to conduct integrity audits of the data stored on cloud servers are urgent problems to be solved, especially when data ownership is traded. Existing solutions are difficult to efficiently conduct integrity audits and ownership transactions for batches of data.

Method used

The original data owner divides the data into multiple data blocks, calculates hash values ​​and audit auxiliary parameters, generates block labels and overall label signature values, and entrusts a third-party auditor to verify data integrity. At the same time, the overall and block labels are updated when data ownership is transferred, so as to achieve high efficiency in data storage and transactions.

Benefits of technology

It enables integrity auditing of data stored on cloud servers and improves the efficiency of batch data transactions during data ownership transactions, while reducing the consumption of computing and communication resources.
