<p>A method for verifying the integrity of a data file stored in storage includes the steps of: obtaining the solution of a coefficient matrix corresponding data prior to storing in storage and a plurality of parity values corresponding to a plurality of rows of the coefficient matrix; selecting at least one row among the rows of the coefficient matrix corresponding the data file stored in the storage; comparing the parity value corresponding to at least one selected row with the value to substitute the solution for at least one selected row; and verifying the integrity about at least one block corresponding to at least one selected row among a plurality of blocks included in the data file stored in the storage based on a comparison result.</p> |
