Description

DESCRIZIONE DESCRIPTION

La presente invenzione ha per oggetto un sistema basato su blockchain per la distruzione certificata dei documenti. The present invention relates to a blockchain-based system for the certified destruction of documents.

Con l’introduzione del nuovo regolamento sulla protezione dei dati personali (GDPR) risulta di notevole importanza il tema della distruzione dei documenti cartacei. With the introduction of the new regulation on the protection of personal data (GDPR), the issue of the destruction of paper documents is of considerable importance.

La blockchain rappresenta un utile strumento tecnologico per perseguire la certificazione delle fasi di un processo grazie all’utilizzo di un ledger distribuito contenente singoli blocchi fra loro correlati mediante hash. The blockchain represents a useful technological tool for pursuing the certification of the phases of a process thanks to the use of a distributed ledger containing individual blocks related to each other by hash.

Nel suddetto contesto, oggetto della nostra invenzione è essenzialmente quello di effettuare un sistema basato su blockchain per la distruzione certificata dei documenti grazie all’utilizzo di una interfaccia di connettività ad Internet (1) caratterizzata da RETE WIFI o Internet Gateway; cassonetto raccoglitore (2) dotato di scheda embedded con sensori magnetici e ad ultrasuoni (3) in grado di generare rispettivamente alert relativi alle aperture dello stesso o di rilevare il livello di portata raggiunto; modulo per la certificazione mediante registrazione su ledger (4) in blockchain degli alert provenienti in broadcast dal cassonetto raccoglitore e delle fasi effettuate dall’operatore relativamente al processo di distruzione mediante interfaccia HMI (5); modulo (6) “miner” presente per ciascun nodo ledger per il controllo certificato del processo di distruzione e per analisi di trend e report. In the above context, the object of our invention is essentially to carry out a blockchain-based system for the certified destruction of documents thanks to the use of an Internet connectivity interface (1) characterized by a WIFI NETWORK or Internet Gateway; collector box (2) equipped with an embedded board with magnetic and ultrasonic sensors (3) capable of generating alerts relating to the openings of the same or detecting the level of flow reached; module for certification by registration on ledger (4) in blockchain of alerts coming in broadcast from the bin and of the phases carried out by the operator in relation to the destruction process via HMI interface (5); module (6) "miner" present for each ledger node for certified control of the destruction process and for trend and report analysis.

A titolo di esempio si riporta una descrizione del funzionamento del sistema. Il singolo cassonetto viene riempito dagli utenti con documenti cartacei da distruggere in modo certificato. L’accesso al cassonetto avviene mediante guida e il monitoraggio delle aperture dello stesso avviene mediante utilizzo di uno o più sensori collegati al dispositivo embedded che monitora il cassonetto. I sensori magnetici posti all’apertura del cassonetto consentono il monitoraggio delle aperture ed eventuali manomissioni. Il livello di occupazione del cassonetto è invece garantito dall’utilizzo di sensore ad ultrasuoni che è tarato sul livello massimo di portata del cassonetto. Tutti gli eventi (alert) generati dal dispositivo embedded presente nel cassonetto vengono registrati su ledger. Sul ledger vengono anche registrati tutti gli eventi generati da interfaccia HMI dell’operatore autorizzato, che ne effettua manutenzione o il prelievo del cassonetto. Tutte le fasi di transito del cassonetto fino alla destinazione di distruzione vengono gestite mediante dispositivo HMI e si provvede per ogni fase ad effettuare la registrazione in blockchain. La registrazione in blockchain riguarda anche la fase di distruzione all’interno del macchinario, che può prevedere il collegamento diretto del macchinario alla blockchain (scrittura del ledger) per la registrazione degli eventi o la registrazione mediante interfaccia HMI effettuata da utente autorizzato. Su ciascun nodo della blockchain è presente un componente “miner” che è utilizzato per effettuare costantemente il controllo di coerenza del ledger, registrando anomalie riscontrate e ripristinando la coerenza del ledger mediante confronto con altri nodi. Il singolo ledger è caratterizzato dalla seguente tupla: By way of example, a description of the operation of the system is provided. The single bin is filled by users with paper documents to be destroyed in a certified way. Access to the box takes place by means of a guide and the monitoring of the openings of the same takes place through the use of one or more sensors connected to the embedded device that monitors the box. The magnetic sensors placed at the opening of the box allow the monitoring of the openings and any tampering. The level of occupation of the bin is instead guaranteed by the use of an ultrasonic sensor which is calibrated on the maximum flow rate of the bin. All events (alerts) generated by the embedded device in the box are recorded on the ledger. The ledger also records all the events generated by the HMI interface of the authorized operator, who carries out maintenance or removal of the bin. All the transit phases of the bin up to the destination of destruction are managed by an HMI device and registration in the blockchain is carried out for each phase. The blockchain registration also concerns the phase of destruction inside the machinery, which can provide for the direct connection of the machinery to the blockchain (writing the ledger) for the recording of events or the recording through the HMI interface carried out by an authorized user. On each node of the blockchain there is a "miner" component which is used to constantly check the coherence of the ledger, recording anomalies found and restoring the coherence of the ledger by comparing it with other nodes. The single ledger is characterized by the following tuple:

T_L = ( Alert, Timestamp, Hash_prev_T_L) T_L = (Alert, Timestamp, Hash_prev_T_L)

dove viene registrato il singolo alert con relativo riferimento temporale e l’hash relativo alla tupla precedente. where the single alert is recorded with its time reference and the hash relating to the previous tuple.

Eventuali anomalie sul calcolo degli hash riscontrati dal “miner” determinano la richiesta di ripristino del singolo ledger gestito. Any anomalies in the calculation of the hashes found by the "miner" determine the request to restore the single managed ledger.
