CHECK-CODE RECOVERY METHOD AND SYSTEM, ELECTRONIC DEVICE AND STORAGE MEDIUM

WIPO Patent Application WO/2024/098647

A1

The present application belongs to the technical field of data storage. Disclosed are a check-code recovery method and system, an electronic device and a storage medium. The recovery method comprises: generating a global check code and a local check code of a data block; determining a first transformation relationship between the data block and the global check code, and determining a second transformation relationship between the data block and the local check code; on the basis of the first transformation relationship and the second transformation relationship, generating a check code transformation relationship between the global check code and the local check code; according to the check code transformation relationship, determining transformation parameters for transformation performed between the global check code and the local check code; and by means of using the transformation parameters, recovering a reported global check code error or a reported local check code error. The described check code recovery process does not need recoding computation according to data codes, so that the check code recovery computation quantity can be reduced, thereby improving the check code recovery efficiency.
