Notarizzazione

Blockchain notarization is a process that allows you to guarantee the authenticity and integrity of a piece of data through immutable registration on a decentralized network, ensuring its traceability and making it inviolable.

Notarization of a hash allows the confidentiality of the unencrypted data to be preserved as the hash is a one-way cryptographic representation that cannot be converted back into the original data, thus protecting its confidentiality during the registration and validation process on the blockchain.

Json

JSON is a lightweight data format used to represent structured information, such as objects and arrays. It is easily readable by machines and widely used for data exchange between applications.

The JSON of a C-BOX assertion is retrievable at the following address. This URL is saved in blockchain at this address.

Hash

The SHA-256 hash (Secure Hash Algorithm 256-bit) is a cryptographic algorithm that converts a data input of any size into a fixed-length hash of 256 bits. The hash generated by SHA-256 is unique for each specific input and offers high security, as even the slightest change to the input data results in a completely different hash.

For this reason, it can be considered a fingerprint of the unencrypted data.

This algorithm is widely used to protect data integrity and ensure confidentiality, due to its resistance to reversibility and its ability to withstand brute force attacks.
