Title:
DATA CONSISTENCY CHECK METHOD AND SYSTEM BASED ON ICC
Document Type and Number:
WIPO Patent Application WO/2022/021849
Kind Code:
A1
Abstract:
A data consistency check method and system based on an ICC, wherein a data chunking algorithm combined with K-means clustering, a complete basis and a PCA dimensionality reduction algorithm is provided, such that under the condition of a large volume of data or distributed storage, representative sub-data can be extracted, and then, an intraclass correlation coefficient (ICC) of the sub-data is calculated, thereby performing a rapid consistency check on data. The data security during data backup and restoration can be effectively ensured; and a data consistency check can be performed under the conditions of the persistence of memory data, data recovery of a disk array device when a system crashes and is subjected to an unexpected power failure, etc., thereby avoiding being unaware of data loss that occurs during the persistence or recovery of data, such that the security and integrity of data can be effectively ensured.
