Private Join and Compute v\u00f5imaldab edastada privaatse andmehulgaga kolmandale osapoolele, kes saab selle anal\u00fc\u00fcsi l\u00e4bi viia ja \u00fcldiselt hinnata erinevusi oma andmehulgaga, kuid ei saa teada konkreetsete andmehaldade v\u00e4\u00e4rtusi. N\u00e4iteks on v\u00f5imalik kr\u00fcpteeritud andmehulgast saada teavet, nagu oma andmehulgaga sobivate identifikaatorite arv ja seotud andmete v\u00e4\u00e4rtuste summad.

Pakutud s\u00fcsteem v\u00f5ib osutuda kasulikuks, n\u00e4iteks siis, kui \u00fches meditsiiniasutuses on teave patsientide terviseseisundi kohta, samas kui teises on andmed uue ennetava ravimi m\u00e4\u00e4ramise kohta. Protokoll 'Private Join and Compute' v\u00f5imaldab, ilma teavet avaldamata, \u00fchendada kr\u00fcpteeritud andmekogusid ja esitada \u00fcldstatistikat, mis aitab m\u00f5ista, kas m\u00e4\u00e4ratud ravim v\u00e4hendab haigusjuhtude arvu v\u00f5i mitte.

Reklaamiv\u00f5rkude kontekstis saab taolisi arvutusi teha reklaamikampaaniate efektiivsuse hindamiseks, kasutades neid kasutajate loetelusid, kellele reklaami n\u00e4idati (v\u00f5i kes klikkisid lingil) ja kes sooritasid ostu veebipoes.<\/p>\n
