Arutelu k\u00e4igus kriitika all oli<\/a><\/noindex> ka Google'i tegevuse kaksikstandard, kus \u00fchelt poolt toetatakse<\/a><\/noindex> meetodeid<\/a><\/noindex> kasutajate identifitseerimise ja j\u00e4lgimise blokeerimist, kuid teisalt ei kiirustu Chrome'ist eemaldama X-Client-Data p\u00e4ise toetust, mida v\u00f5ib kasutada brauseri instantside tuvastamiseks Google'i teenustes.<\/p>\n

P\u00e4is X-Client-Data ei ole varjatud funktsioon ja selle k\u00e4itumine detailsemalt<\/a><\/noindex> dokumendis. X-Client-Data kaudu kogub Google teavet teatud katsetamisv\u00f5imaluste aktiivsuse kohta Chrome'is, sidudes need oma veebisaitidega (n\u00e4iteks katse k\u00e4igus v\u00f5ib Google Youtube'is aktiveerida teatud testimisv\u00f5imalusi, kui need on brauseris toetatud, v\u00f5i proovida seostada ilmnevaid probleeme katsetamisfunktsioonide aktiveerimisega). <\/p>\n

P\u00e4is v\u00e4lja antud<\/a><\/noindex> ainult p\u00e4ringutele Google'i saitidele, mis vastavad mustritele «*.doubleclick.net», «*.googlesyndication.com», «www.googleadservices.com», «*.google.<TLD<\/a><\/noindex>>» ja «*.youtube.<TLD>», ning mida edastatakse HTTPS-i kaudu. Inkognito re\u017eiimis ei t\u00e4ideta p\u00e4ist, kuid juhul, kui kasutaja autentitud profiil Google'is vahetatakse k\u00fclalisprofii vastu v\u00f5i kui kutsutakse andmete kustutamise toimingut, ei l\u00e4htestata p\u00e4ist ja see j\u00e4tkab endise v\u00e4\u00e4rtusega saatmist.<\/p>\n

\"X-Client-Data<\/a><\/noindex><\/center><\/p>\n

On v\u00e4idetud, et pealkiri ei sisalda isiklikult tuvastatavat teavet, vaid kirjeldab Chrome'i seadistuste seisundit ja aktiivseid eksperimentaalseid v\u00f5imalusi. Kui seadistustes on v\u00e4lja l\u00fclitatud brauseri kasutamise telemeetriate edastamine ja kokkuvarisemiste aruannete genereerimine, siis X-Client-Data pealkirja genereerimise alusel kasutatav baasv\u00e4\u00e4rtus kasutab vaid 13 bitti entropiat (8000 erinevat kombinatsiooni), mis on tuvastamiseks ebapiisav. <\/p>\n

Arvestades, et p\u00e4ises kodeeritakse ka m\u00f5ned s\u00fcsteemi seaded ja parameetrid, sobib X-Client-Data sisu t\u00e4iendavaks andmeallikaks kasutaja kaudseks tuvastamiseks l\u00fchikese aja jooksul (eksperimentaalsed v\u00f5imalused aktiveeritakse ja deaktiveeritakse aja jooksul, mis toob kaasa X-Client-Data v\u00e4\u00e4rtuse perioodilise muutumise). <\/p>\n

Sellegipoolest, peale algse entropia X-Client-Data v\u00e4\u00e4rtuse genereerimisel kasutatakse ka seed-jada, mida tagastavad Google'i serverid ja mis s\u00f5ltub riigist, IP-aadressist ja muudest kriteeriumidest, mida Google peab oluliseks (n\u00e4iteks ei ole midagi takistamas, et tagastada suur juhuslik jada, mis muutub t\u00e4pseks identifikaatoriks).
\nLisaks sellele ei v\u00e4lista Google'i domeenide mustrite kontroll X-Client-Data saatmisel olukordi, kus r\u00fcndaja v\u00f5ib registreerida domeeni, nagu «youtube.xn--55qx5d», ja hakata koguma identifikaatoreid.<\/p>\n
