Descrizione dell’invenzione industriale dal titolo “Metodo e apparecchiatura per impedire irreversibilmente la lettura di dati presenti su un circuito integrato” Description of the industrial invention entitled "Method and equipment to irreversibly prevent the reading of data on an integrated circuit"
DESCRIZIONE DESCRIPTION
Ambito dell’invenzione Scope of the invention
La presente invenzione riguarda il settore dello smaltimento di smart card. The present invention relates to the smart card disposal sector.
In particolare, l’invenzione riguarda un metodo e un’apparecchiatura per impedire irreversibilmente la lettura di dati presenti su un circuito integrato di una smart card. In particular, the invention relates to a method and an equipment to irreversibly prevent the reading of data present on an integrated circuit of a smart card.
Descrizione della tecnica nota Description of the prior art
Come noto, una smart card è un dispositivo hardware che può comprendere un insieme di tecnologie, tra cui microprocessori e memorie RAM, integrate all’interno di un circuito integrato, in grado di permettere l’elaborazione e la memorizzazione di dati, garantendo elevati standard di sicurezza. As is known, a smart card is a hardware device that can include a set of technologies, including microprocessors and RAM memories, integrated within an integrated circuit, capable of allowing data processing and storage, guaranteeing high standards. safety.
Per tale motivo, ad oggi, la tecnologia della smart card viene impiegata in numerose applicazioni, ad esempio nelle carte di credito, nelle SIM dei telefoni cellulari, nei documenti di identità digitali, nelle carte per la firma digitale, e altro ancora. For this reason, smart card technology is currently used in numerous applications, such as credit cards, mobile phone SIM cards, digital identity documents, digital signature cards, and more.
Tuttavia, quando tali smart card risultano scadute o danneggiate, esse devono essere smaltite garantendo che i dati contenuti non siano più leggibili, soprattutto in caso di dati sensibili, quali codici bancari o informazioni confidenziali. However, when these smart cards are expired or damaged, they must be disposed of ensuring that the data contained is no longer readable, especially in the case of sensitive data, such as bank codes or confidential information.
Tale danneggiamento irreversibile dei dati non risulta semplice, poiché, anche nel caso in cui un circuito integrato non risulti più leggibile mediante il dispositivo predisposto, i dati possono comunque essere recuperati mediante speciali apparecchiature. This irreversible damage to the data is not easy, since, even if an integrated circuit is no longer legible by means of the predisposed device, the data can still be recovered by means of special equipment.
Attualmente, i metodi maggiormente utilizzati per la distruzione dei dati sono di tipo meccanico, ad esempio mediante trafilatura e/o triturazione del circuito integrato. Currently, the most widely used methods for data destruction are of the mechanical type, for example by drawing and / or shredding the integrated circuit.
Tuttavia, tali sistemi di distruzione dei dati non distruggono la struttura fisica del circuito integrato e tali dati non vengono di fatto completamente rimossi, permettendone una potenziale ricostruzione mediante apparecchiature specifiche. Per tale motivo, negli ultimi anni si sono registrati frequenti casi di ripristino dei dati presenti su carte di credito smaltite dagli istituti bancari, permettendo prelievi non autorizzati sui conti correnti, ed evidenziando il fatto che tali sistemi meccanici non sono in grado di garantire una distruzione irreversibile dei dati sui circuiti integrati. However, such data destruction systems do not destroy the physical structure of the integrated circuit and such data is not actually completely removed, allowing for potential reconstruction using specific equipment. For this reason, in recent years there have been frequent cases of restoring data on credit cards disposed of by banks, allowing unauthorized withdrawals on current accounts, and highlighting the fact that these mechanical systems are not able to guarantee destruction. irreversible data on integrated circuits.
Si sente pertanto l’esigenza di un metodo per la distruzione irreversibile e verificabile dei dati sui circuiti integrati di smart card. There is therefore a need for a method for irreversible and verifiable destruction of data on smart card integrated circuits.
Sintesi dell’invenzione Summary of the invention
È quindi scopo della presente invenzione fornire un metodo per impedire irreversibilmente l’accesso ai dati presenti su un circuito integrato di una smart card che distrugga la struttura fisica dei semiconduttori del circuito integrato, garantendo l’impossibilità di recupero di tali dati. It is therefore the purpose of the present invention to provide a method to irreversibly prevent access to the data present on an integrated circuit of a smart card that destroys the physical structure of the semiconductors of the integrated circuit, ensuring the impossibility of recovering such data.
È inoltre scopo della presente invenzione fornire un siffatto metodo che permetta di verificare e certificare l’avvenuta distruzione dei dati e che, in caso contrario, non permetta lo smaltimento della smart card. It is also the purpose of the present invention to provide such a method that allows you to verify and certify the destruction of the data and which, otherwise, does not allow the disposal of the smart card.
È ancora scopo della presente invenzione fornire un siffatto metodo che possa essere automatizzato in modo da consentire uno smaltimento rapido. It is still an object of the present invention to provide such a method which can be automated so as to allow rapid disposal.
È un ulteriore scopo della presente invenzione fornire un’apparecchiatura che permetta di realizzare tale metodo. It is a further object of the present invention to provide an equipment that allows to carry out this method.
Questi ed altri scopi sono raggiunti da un metodo per impedire irreversibilmente la lettura dei dati presenti su un circuito integrato di una smart card secondo le rivendicazioni da 1 a 7. These and other purposes are achieved by a method for irreversibly preventing the reading of the data present on an integrated circuit of a smart card according to claims 1 to 7.
Tali scopi sono inoltre raggiunti da un’apparecchiatura per impedire irreversibilmente l’accesso ai dati presenti su un circuito integrato di una smart card secondo le rivendicazioni da 8 a 10. These purposes are also achieved by an equipment to irreversibly prevent access to the data present on an integrated circuit of a smart card according to claims 8 to 10.
Breve descrizione dei disegni Brief description of the drawings
Ulteriori caratteristiche e/o vantaggi della presente invenzione risulteranno più chiari con la descrizione che segue di una sua forma realizzativa, fatta a titolo esemplificativo e non limitativo, con riferimento ai disegni annessi in cui: Further characteristics and / or advantages of the present invention will become clearer with the following description of an embodiment thereof, given by way of non-limiting example, with reference to the attached drawings in which:
- la figura 1 mostra, in un diagramma di flusso, le successive fasi del metodo per impedire irreversibilmente l'accesso ai dati presenti su un circuito integrato di una smart card, secondo la presente invenzione; Figure 1 shows, in a flow diagram, the subsequent steps of the method for irreversibly preventing access to the data present on an integrated circuit of a smart card, according to the present invention;
- la figura 2 mostra, in maniera schematica, il processo di funzionamento di un’apparecchiatura per la distruzione di dati presenti su un circuito integrato di una smart card, secondo la presente invenzione. - Figure 2 schematically shows the operating process of an equipment for the destruction of data present on an integrated circuit of a smart card, according to the present invention.
Descrizione di alcune forme realizzative preferite Il diagramma di flusso 300 di figura 1 mostra schematicamente un metodo, secondo la presente invenzione, per impedire irreversibilmente l'accesso ai dati presenti su un circuito integrato 200 di una smart card. Description of some preferred embodiments The flow chart 300 of Figure 1 schematically shows a method, according to the present invention, for irreversibly preventing access to the data present on an integrated circuit 200 of a smart card.
In particolare, con riferimento anche alla figura 2, il metodo prevede una prima fase di predisposizione di un’apparecchiatura 100 per la distruzione di dati comprendente un dispositivo di induzione di corrente elettrica 110, un dispositivo di lettura 120 atto a leggere i dati presenti sul circuito integrato 200 e mezzi di movimentazione 130, ad esempio un rullo trasportatore, atti a movimentare in maniera automatica il circuito integrato 200 [301]. In particular, with reference also to Figure 2, the method provides for a first stage of setting up an apparatus 100 for the destruction of data comprising an electric current induction device 110, a reading device 120 adapted to read the data present on the integrated circuit 200 and handling means 130, for example a conveyor roller, adapted to automatically move the integrated circuit 200 [301].
Il metodo prevede poi le fasi di disposizione del circuito integrato 200 in prossimità del dispositivo di induzione di corrente elettrica 110 [302] e induzione di corrente elettrica in detto circuito integrato per un predeterminato lasso di tempo Δ t [303]. The method then provides for the steps of arranging the integrated circuit 200 in proximity to the electric current induction device 110 [302] and the induction of electric current in said integrated circuit for a predetermined period of time Δ t [303].
In particolare, il dispositivo di induzione di corrente elettrica 110 può essere una valvola magnetron atta ad emettere microonde ad una frequenza f pari a 2,34 Ghz per indurre corrente elettrica nel circuito integrato 200. Il lasso di tempo Δ t è compreso tra 0,5 secondi e 10 secondi. In particular, the electric current induction device 110 can be a magnetron valve capable of emitting microwaves at a frequency f equal to 2.34 Ghz to induce electric current in the integrated circuit 200. The time span Δ t is between 0, 5 seconds and 10 seconds.
Le microonde emesse invadono, per induzione elettromagnetica, la struttura fisica del circuito integrato 200 generando all’interno di esso forti correnti elettriche indotte che, data la loro potenza e il tempo di applicazione, rompono per effetto termico ed elettromagnetico la struttura dei semiconduttori costituenti la parte periferica del circuito integrato 200. The microwaves emitted invade, by electromagnetic induction, the physical structure of the integrated circuit 200, generating within it strong induced electric currents which, given their power and the time of application, break the structure of the semiconductors constituting the circuit due to thermal and electromagnetic effects. peripheral part of the integrated circuit 200.
Il metodo prevede quindi una fase di lettura del circuito integrato 200 mediante il dispositivo di lettura 120 per distinguere circuiti integrati con dati non leggibili 200a da circuiti integrati con dati leggibili 200b [304]. Questa fase consente di verificare che i dati siano effettivamente stati distrutti e, in caso contrario, di non consentire la dismissione di circuiti integrati 200b con dati ancora recuperabili. The method therefore provides a step of reading the integrated circuit 200 by means of the reading device 120 to distinguish integrated circuits with unreadable data 200a from integrated circuits with readable data 200b [304]. This phase makes it possible to verify that the data has actually been destroyed and, if not, to not allow the disposal of integrated circuits 200b with data that can still be recovered.
Vi è quindi una fase di separazione, mediante i mezzi di movimentazione 130, dei circuiti integrati con dati non leggibili 200a dai circuiti integrati con dati leggibili 200b [305]. In particolare, i circuiti integrati con dati non leggibili 200a passano alla successiva fase di distruzione meccanica mediante, ad esempio, triturazione e/o calandratura e/o trafilatura [306]. I circuiti integrati con dati leggibili 200b, invece, possono essere sottoposti nuovamente alle fasi sopra descritte, fino a che non sia verificata l’effettiva e irreversibile distruzione dei dati memorizzati. There is therefore a step of separating, by means of the handling means 130, the integrated circuits with unreadable data 200a from the integrated circuits with readable data 200b [305]. In particular, the integrated circuits with unreadable data 200a pass to the subsequent mechanical destruction step by, for example, shredding and / or calendering and / or drawing [306]. The integrated circuits with readable data 200b, on the other hand, can be subjected again to the steps described above, until the effective and irreversible destruction of the stored data is verified.
Vantaggiosamente, a valle della fase di disposizione di detto circuito integrato 200 in prossimità del dispositivo di induzione di corrente elettrica 110, può essere prevista una fase di trasferimento dei dati presenti sul circuito integrato 200 all’interno di un database. Advantageously, downstream of the arrangement step of said integrated circuit 200 in proximity to the electric current induction device 110, a step of transferring the data present on the integrated circuit 200 into a database can be provided.
La descrizione di cui sopra di alcune forme realizzative specifiche è in grado di mostrare l’invenzione dal punto di vista concettuale in modo che altri, utilizzando la tecnica nota, potranno modificare e/o adattare in varie applicazioni tale forma realizzativa specifica senza ulteriori ricerche e senza allontanarsi dal concetto inventivo, e, quindi, si intende che tali adattamenti e modifiche saranno considerabili come equivalenti della forma realizzativa specifica. I mezzi e i materiali per realizzare le varie funzioni descritte potranno essere di varia natura senza per questo uscire dall’ambito dell’invenzione. Si intende che le espressioni o la terminologia utilizzate hanno scopo puramente descrittivo e per questo non limitativo.

The means and materials for carrying out the various functions described may be of various nature without thereby departing from the scope of the invention. It is understood that the expressions or terminology used have a purely descriptive purpose and therefore not limitative.
