Abstract
A parity block generation method and apparatus are disclosed. The method comprises: for a plurality of original data blocks for which parity blocks are to be generated, determining a global coding matrix for the plurality of original data blocks; for each local domain that is obtained by dividing the plurality of original data blocks, determining a local coding matrix of the local domain on the basis of the global coding matrix, wherein each local domain comprises original data blocks that belong to the local domain; and generating, on the basis of the global coding matrix, global parity blocks for the plurality of original data blocks, and generating, on the basis of the local coding matrix of each local domain, a local reconstruction parity block of each local domain, such that the global parity blocks have a derivation relationship with the local reconstruction parity block of each local domain.
