METHOD FOR CHECKING THE INTEGRITY OF A DIGITAL DATA BLOCK |
| 摘要 |
The present invention relates to methods for verifying the integrity of data blocks and for accessing the blocks and relates more particularly to a method for verifying the integrity of a digital data block, the method comprising steps of: searching for a digital fingerprint in a data block of a reference point, calculating a digital fingerprint by applying a fingerprint calculation function to the data block, the fingerprint calculated having a value which depends on each of the bits of the data block excluding the bits of a fingerprint found in the data block, and verifying the fingerprint found in the data block by comparing it with the fingerprint calculated. |

1. A method for verifying the integrity of a digital data block, the method comprising steps of:
searching for a digital fingerprint in a first data block, by means of a first reference point, calculating a first digital fingerprint by applying a fingerprint calculation function to the first data block, the first fingerprint calculated having a value which depends on each of the bits of the first data block excluding the bits of a fingerprint found in the first data block, and verifying the fingerprint found in the first data block by comparing it with the first fingerprint calculated. |
