Koment\u00e1\u0159 k filmu, n\u00e1zvu kav\u00e1rny, m\u011bstu, kon\u00ed\u010dku nebo povol\u00e1n\u00ed: Samy o sob\u011b takov\u00e9 informace prozrazuj\u00ed jen m\u00e1lo. Nov\u00e1 studie v\u0161ak ukazuje, \u017ee um\u011bl\u00e1 inteligence z nich dok\u00e1\u017ee sestavit p\u0159ekvapiv\u011b p\u0159esn\u00fd digit\u00e1ln\u00ed otisk prstu.<\/span><\/p>\n

Z\u0159ejm\u00e9 indicie, jako jsou osobn\u00ed webov\u00e9 str\u00e1nky, n\u00e1zvy soci\u00e1ln\u00edch m\u00e9di\u00ed a p\u0159ezd\u00edvky na GitHubu, byly p\u0159edem odstran\u011bny.<\/span><\/p>\n

Cena experimentu: pouh\u00fdch <\/span>2 000 dolar\u016f, neboli jeden a\u017e \u010dty\u0159i dolary za profil<\/span><\/strong> .<\/span><\/p>\n

55 procent identifikov\u00e1no \u2013 z 89 000 u\u017eivatel\u016f<\/span><\/h2>\n

V\u00fdzkumn\u00edci zanechali zd\u00e1nliv\u011b ne\u0161kodn\u00e9 informace: jm\u00e9na koleg\u016f, instituc\u00ed a m\u00edstn\u00edch podnik\u016f, m\u00edsta bydli\u0161t\u011b, z\u00e1jmy, demografick\u00e9 informace a technick\u00e9 dovednosti.<\/span><\/p>\n

Um\u011bl\u00e1 inteligence tyto informace zkombinovala a mezi <\/span>89 000 u\u017eivateli<\/span><\/strong> vyhledala vhodn\u00e9 shody. V\u00fdsledek: S p\u0159esnost\u00ed 90 procent bylo identifikov\u00e1no 55,2 procenta vyhledan\u00fdch profil\u016f. S p\u0159esnost\u00ed 99 procent st\u00e1le identifikovala 45,1 procenta.<\/span><\/p>\n

Star\u0161\u00ed metoda statistick\u00e9 deanonymizace dos\u00e1hla se stejn\u00fdmi daty pouze 0,1 procenta.<\/span><\/p>\n

Z\u00e1sadn\u00ed rozd\u00edl: Co d\u0159\u00edve vy\u017eadovalo \u010dasov\u011b n\u00e1ro\u010dnou detektivn\u00ed pr\u00e1ci, lze nyn\u00ed automatizovat um\u011blou inteligenc\u00ed a prov\u00e1d\u011bt s extr\u00e9mn\u011b n\u00edzk\u00fdmi n\u00e1klady.<\/span><\/p>\n

\u010c\u00edm v\u00edce toho odhal\u00edte, t\u00edm sn\u00e1ze v\u00e1s um\u011bl\u00e1 inteligence najde<\/span><\/h2>\n

Dal\u0161\u00ed experiment s u\u017eivateli Redditu uk\u00e1zal, \u017ee i zd\u00e1nliv\u011b trivi\u00e1ln\u00ed informace o filmov\u00fdch preferenc\u00edch mohou p\u0159isp\u011bt k identifikaci. \u010c\u00edm v\u00edce n\u011bkdo publikuje, t\u00edm unik\u00e1tn\u011bj\u0161\u00ed se jeho digit\u00e1ln\u00ed profil st\u00e1v\u00e1.<\/span><\/p>\n

V\u00fdzkumn\u00edci shrnuj\u00ed princip jednodu\u0161e: m\u011bsto, profese, \u00fa\u010dast na konferenci nebo specializovan\u00fd kon\u00ed\u010dek zu\u017euj\u00ed okruh mo\u017en\u00fdch jedinc\u016f. <\/span>Tato kombinace se m\u016f\u017ee st\u00e1t jedine\u010dn\u00fdm otiskem prstu.<\/span><\/strong><\/p>\n

I velikost platformy nab\u00edz\u00ed jen omezenou ochranu. V\u00fdzkumn\u00edci odhaduj\u00ed, \u017ee jejich metoda by st\u00e1le mohla naj\u00edt p\u0159ibli\u017en\u011b 45 procent hledan\u00fdch osob v souboru jednoho milionu lid\u00ed a asi 27 procent v teoretick\u00e9m souboru 100 milion\u016f kandid\u00e1t\u016f.<\/span><\/p>\n

V\u00fdkonn\u00fd n\u00e1stroj pro dohled<\/span><\/h2>\n

D\u016fsledky jsou zna\u010dn\u00e9. Vl\u00e1dy by mohly tyto metody vyu\u017e\u00edt k propojen\u00ed pseudonymn\u00edch \u00fa\u010dt\u016f <\/span>novin\u00e1\u0159\u016f, disident\u016f nebo aktivist\u016f<\/span><\/strong> se skute\u010dn\u00fdmi lidmi. Spole\u010dnosti a zprost\u0159edkovatel\u00e9 dat by mohli propojovat profily nap\u0159\u00ed\u010d r\u016fzn\u00fdmi platformami.<\/span><\/p>\n

K tomu nikdo nemus\u00ed hackovat datab\u00e1ze: Studie pou\u017eila v\u00fdhradn\u011b ve\u0159ejn\u011b dostupn\u00e9 informace, kter\u00e9 sami u\u017eivatel\u00e9 zve\u0159ejnili.<\/span><\/p>\n

Dokonce i bezpe\u010dnostn\u00ed filtry syst\u00e9m\u016f um\u011bl\u00e9 inteligence mohou nab\u00edzet jen malou ochranu. \u00datok lze rozd\u011blit na zd\u00e1nliv\u011b ne\u0161kodn\u00e9 \u00fakoly \u2013 shrnut\u00ed profil\u016f, porovn\u00e1n\u00ed dokument\u016f, hodnocen\u00ed kandid\u00e1t\u016f. Nav\u00edc u model\u016f s otev\u0159en\u00fdm zdrojov\u00fdm k\u00f3dem lze ochrann\u00e9 mechanismy odstranit.<\/span><\/p>\n

Digit\u00e1ln\u00ed identifikace probl\u00e9m zhor\u0161uje<\/span><\/h2>\n

Tento v\u00fdvoj se st\u00e1v\u00e1 obzvl\u00e1\u0161t\u011b explozivn\u00edm ve sv\u011btle digit\u00e1ln\u00edch identit a online ov\u011b\u0159ov\u00e1n\u00ed v\u011bku. \u010casto se slibuje, \u017ee u\u017eivatel\u00e9 mohou prok\u00e1zat svou identitu jednou a pot\u00e9 z\u016fstanou pseudonymn\u00ed.<\/span><\/p>\n

Pokud ale um\u011bl\u00e1 inteligence ji\u017e dok\u00e1\u017ee identifikovat osobu na z\u00e1klad\u011b j\u00edm publikovan\u00e9ho obsahu, toto rozli\u0161en\u00ed se st\u00e1v\u00e1 st\u00e1le k\u0159eh\u010d\u00edm. Studie nedokazuje, \u017ee digit\u00e1ln\u00ed identifika\u010dn\u00ed \u00fadaje automaticky odhaluj\u00ed anonymn\u00ed profily. Ukazuje v\u0161ak, jak snadno lze nyn\u00ed rozpt\u00fdlen\u00e9 online stopy kombinovat a vytv\u00e1\u0159et tak identitu v re\u00e1ln\u00e9m sv\u011bt\u011b.<\/span><\/p>\n

Nebezpe\u010d\u00ed tedy nespo\u010d\u00edv\u00e1 ve velk\u00e9 kr\u00e1de\u017ei dat, ale v tis\u00edc\u00edch mal\u00fdch detail\u016f, kter\u00e9 lid\u00e9 v pr\u016fb\u011bhu let dobrovoln\u011b zve\u0159ejnili. D\u0159\u00edve byly tyto stopy roztrou\u0161eny po internetu. Dnes je um\u011bl\u00e1 inteligence dok\u00e1\u017ee d\u00e1t dohromady za p\u00e1r dolar\u016f \u2013 dokud se za pseudonymem neobjev\u00ed skute\u010dn\u00e9 jm\u00e9no.<\/span><\/strong><\/p>\n<\/div>\n<\/div>\n
