Google ha presentato<\/a><\/noindex> protocollo crittografico per l'elaborazione multi-party riservata Private Join and Compute<\/a><\/noindex>, che consente di analizzare e calcolare set di dati crittografati provenienti da pi\u00f9 partecipanti, mantenendo la riservatezza dei dati di ciascun partecipante (ogni partecipante non ha la possibilit\u00e0 di accedere alle informazioni sui dati degli altri partecipanti, ma pu\u00f2 eseguire calcoli aggregati su di essi senza decrittazione). Il codice di implementazione del protocollo \u00e8 aperto<\/a><\/noindex> sotto licenza Apache 2.0.<\/p>\n

Private Join and Compute consente di inoltrare un insieme privato di record a una terza parte, che potr\u00e0 eseguire analisi e valutare in forma aggregata le differenze con il proprio set, ma non ha accesso ai valori specifici dei record. Per esempio, \u00e8 possibile ottenere, in un set di dati crittografato, informazioni come il numero di identificatori corrispondenti al proprio set e le somme dei valori dei record con identificatori corrispondenti. Tuttavia, non \u00e8 possibile sapere quali valori e identificatori siano presenti nel set.<\/p>\n

Il protocollo Private Join and Compute, noto anche come Private Intersection-Sum, fondato<\/a><\/noindex> si basa sulla combinazione del protocollo di trasmissione casuale dimenticabile<\/a><\/noindex> (Random Oblivious Transfer), criptati filtri di Bloom<\/a><\/noindex> e doppia mascheratura Poliga \u2014 Hellman<\/a><\/noindex>.<\/p>\n

Il sistema proposto pu\u00f2 rivelarsi utile, ad esempio, quando un'istituzione medica ha informazioni sulla salute dei pazienti, mentre un'altra ha dati sulla somministrazione di un nuovo farmaco preventivo. Il protocollo \u00abPrivate Join and Compute\u00bb permette di unire set di dati criptati senza rivelare informazioni, producendo statistiche generali che consentono di capire se il farmaco assegnato riduce l'incidenza della malattia o meno. Un altro esempio \u00e8 l'analisi basata sui dati degli incidenti dell'agenzia di polizia e sull'uso di tecnologie avanzate di sicurezza nei veicoli, per valutare se l'introduzione di questi strumenti influenzi il numero di incidenti.<\/p>\n

Un altro esempio \u00e8 quando, utilizzando il database dei dipendenti di un'azienda e i dati sugli acquisti di un'altra, si pu\u00f2 calcolare quanti dipendenti della prima azienda hanno effettuato acquisti nella seconda e per quale importo. Nel contesto delle reti pubblicitarie, si possono effettuare calcoli simili per valutare l'efficacia delle campagne pubblicitarie, operando con liste di utenti a cui \u00e8 stata mostrata la pubblicit\u00e0 (o che hanno fatto clic sul link) e che hanno effettuato acquisti nell'e-commerce.<\/p>\n
