Notarising a document consists in using a Blockchain ledger to certify the date of a document and the fact that it has not been altered over time.
This is guaranteed by using hashing functions that can track an entire document back to a single alphanumeric code with a fixed length and by sharing the hash thus created on the blockchain.
Any changes to the original document would generate an entirely different hash that, if compared with the original one on the blockchain, would make the change easy to identify.
All you need is a copy of the original data (a file, a log file or a record) to be able to recalculate its hash values at any time and check the document.
Notarisation, timestamps and data certification applied to your company’s needs.
By using proprietary connectors, it is possible to notarise any type of data by inserting its hash value in a blockchain chain.
This creates an independent, universal and transparent record that, thanks to the timestamp and the properties of the hash functions, objectively certifies any tampering with the data itself and its existence in a given form starting from a given time.
