US Patent 11496305 Item integrity verification

Various embodiments include processing devices and methods for integrity verification of a news item. A processor of a network element may obtain an electronic news item that is ready for publication, and may determine a fingerprint using one or more portions of the electronic news item. The processor may determine for the electronic news item a record including the determined fingerprint and a second fingerprint of a previous electronic news item. The processor may store the determined record in a publicly available digital ledger, embed the determined fingerprint in the electronic news item, and publish the electronic news item. A computing device may obtain the published news item and may use the embedded fingerprint in the record that is stored in the digital ledger to verify the integrity of the electronic news item.
