Anal\u00fc\u00fcs 52 000 Firefoxi kasutaja poolt antud k\u00fclastusprofilist, kes osalesid eksperimendis, n\u00e4itas, et veebisaitide k\u00fclastamiseelistused on igale kasutajale iseloomulikud ja p\u00fcsivad. Saadud k\u00fclastusprofiilide unikaalsus oli 99%. Samuti s\u00e4ilib profiilide k\u00f5rge unikaalsus isegi juhul, kui valim piiratakse ainult sadade populaarsete saitidega.<\/p>\n

Korduvate tuvastamise v\u00f5imaluse kontroll viidi l\u00e4bi kahe n\u00e4dala eksperimentaalses uuringus - esimesel n\u00e4dalal k\u00fclastamise andmeid p\u00fc\u00fcti siduda teise n\u00e4dala andmetega. Selgus, et 50% kasutajatest, kes olid k\u00fclastanud 50 v\u00f5i enamat erinevat domeeni, oli v\u00f5imalik uuesti tuvastada. Kui k\u00fclastati 150 v\u00f5i enamat erinevat domeeni, suurenes korduva tuvastamise ulatus 80% -ni. Kontroll viidi l\u00e4bi 10 000 saidi valimis andmete simuleerimiseks, mida suudavad hankida suured sisu pakkujad (n\u00e4iteks Google suudab j\u00e4lgida 9823 saidi k\u00fclastusi neist 10000, Facebook 7348 ja Verizon 5500).<\/p>\n

Antud omadus v\u00f5imaldab suurte populaarsete ressursside omanikul kasutajaid t\u00f5en\u00e4oliselt uuesti tuvastada. N\u00e4iteks v\u00f5ivad ettev\u00f5tted Google, Facebook ja Twitter, mille vidinad on paigutatud kolmandate osapoolte saitidele, teoreetiliselt uuesti tuvastada umbes 80% kasutajatest.<\/p>\n

Teatud varem avatud saite on v\u00f5imalik tuvastada ka kaudsete meetodite abil, n\u00e4iteks JavaScript'i koodis populaarsete domeenide proovimise kaudu, hinnates erinevusi ressursside laadimise viivitustes - kui sait on hiljuti kasutaja poolt avatud, siis ressurss v\u00e4ljastatakse brauseri vahem\u00e4lust peaaegu koheselt. Varasemalt v\u00f5idi avatud lehtede tuvastamiseks kasutada hinnang<\/a><\/noindex> HSTS seadeid (kui avada veebisait HSTS-iga, suunatakse HTTP-p\u00e4ring ka kohe HTTPS-ile ilma HTTP-katseta) ja anal\u00fc\u00fcs<\/a><\/noindex> CSS omaduse \"visited\" seisundeid. <\/p>\n

Taas selliseid k\u00fclastuste ajalugu m\u00e4\u00e4ramise meetodeid CSS-i p\u00f5hjal kasutati sarnases uuringus, mida viidi l\u00e4bi<\/a><\/noindex> 2009. aastast 2011. aastani. See uuring n\u00e4itas, et 42% kasutajatest suudeti tuvastada 50 lehe kontrollimise korral ja 70% 500 lehe kontrollimise korral. Mozilla uuring kinnitas<\/a><\/noindex> ja t\u00e4psustas varasema v\u00e4ljaande j\u00e4reldusi, samal ajal suurendades oluliselt k\u00fclastuste ajaloode m\u00e4\u00e4ramise t\u00e4psust ning laiendades kontrollitud domeenide arvu 6000-lt kuni 10000-le (kokku saadi andmed 660000 domeeni kohta, kuid identifitseerimise hinnangu tegemisel kasutati valim 10 000 k\u00f5ige populaarsemast domeenist). <\/p>\n
