Medarbejdere hos Mozilla har offentliggjort<\/a><\/noindex> resultaterne af unders\u00f8gelsen af mulighederne for identifikation af brugere baseret p\u00e5 browserbes\u00f8gsprofiler, der kan v\u00e6re synlige for tredjepart og websteder. Analysen af 52.000 bes\u00f8gsprofiler givet af Firefox-brugere, der deltog i eksperimentet, viste, at pr\u00e6ferencerne for bes\u00f8gte websteder er karakteristiske for hver enkelt bruger og forbliver konstante. Unikheden af de opn\u00e5ede bes\u00f8gsprofiler var 99%. Den h\u00f8je grad af unikhed i profilerne opretholdes ogs\u00e5, selv n\u00e5r man begr\u00e6nser udvalget til blot et hundrede popul\u00e6re websteder.<\/p>\n

\"Identifikation<\/a><\/noindex><\/center><\/p>\n

Unders\u00f8gelsen af mulighederne for genidentifikation blev gennemf\u00f8rt i l\u00f8bet af en to ugers eksperiment - bes\u00f8gsdataene fra den f\u00f8rste uge blev sammenlignet med dataene fra den anden uge. Det viste sig, at 50% af brugerne, der havde bes\u00f8gt 50 eller flere forskellige dom\u00e6ner, kunne genidentificeres. Ved bes\u00f8g p\u00e5 150 eller flere forskellige dom\u00e6ner steg genidentifikationsgraden til 80%. Unders\u00f8gelsen blev udf\u00f8rt p\u00e5 et udvalg af 10.000 websteder for at simulere data, som store indholdsudbydere kunne f\u00e5 (for eksempel kan Google overv\u00e5ge 9823 sitebes\u00f8g ud af de 10.000, Facebook 7348, Verizon 5500).<\/p>\n

Denne egenskab giver store ejere af popul\u00e6re ressourcer en tilstr\u00e6kkelig h\u00f8j sandsynlighed for at identificere brugere. For eksempel kan virksomheder som Google, Facebook og Twitter, hvis widgets er placeret p\u00e5 tredjepartswebsteder, teoretisk set genidentificere omkring 80% af brugerne.<\/p>\n

\"Identifikation<\/a><\/noindex><\/center><\/p>\n

Tidligere \u00e5bne websteder kan ogs\u00e5 identificeres indirekte, for eksempel ved at iterere gennem popul\u00e6re dom\u00e6ner i JavaScript-koden og vurdere forskellene i indl\u00e6sningstider af ressourcer - hvis siden for nylig blev \u00e5bnet af brugeren, vil ressourcen blive leveret fra browserens cache n\u00e6sten \u00f8jeblikkeligt. Tidligere blev der anvendt vurderingen<\/a><\/noindex> caching-indstillinger for HSTS (n\u00e5r man \u00e5bner et websted med HSTS, blev HTTP-anmodningen straks omdirigeret til HTTPS uden fors\u00f8g p\u00e5 at kontakte via HTTP) og af deciderede enoghalvtredsere siger os, at kun 20% af dem blev grundlagt af \u00e9n person. Men er det v\u00e6rd at tage h\u00f8jde for denne v\u00e6rdi, n\u00e5r hver milliard-dollar virksomhed er en unik og uforlignelig historie? Desuden er en stor statistisk stikpr\u00f8ve altid mere pr\u00e6cis. M\u00f8det er nedbrudt.<\/a><\/noindex> CSS-egenskaben \"visited\". <\/p>\n

S\u00e5danne metoder til bestemmelse af bes\u00f8gshistorik baseret p\u00e5 CSS blev anvendt i en lignende unders\u00f8gelse, der blev udf\u00f8rt<\/a><\/noindex> Fra 2009 til 2011 viste denne unders\u00f8gelse muligheden for at identificere 42% af brugerne ved at gennemg\u00e5 50 sider og 70% ved at gennemg\u00e5 500 sider. Unders\u00f8gelsen fra Mozilla bekr\u00e6ftede<\/a><\/noindex> og pr\u00e6ciserede konklusionerne fra den tidligere publikation, samtidig med at n\u00f8jagtigheden af bestemmelsen af bes\u00f8gs historie blev v\u00e6sentligt forbedret, og omfanget af de kontrollerede dom\u00e6ner blev udvidet fra 6000 til 10000 (der blev samlet data om 660000 dom\u00e6ner, men i vurderingen af identifikationen blev der anvendt et udvalg p\u00e5 10.000 af de mest popul\u00e6re dom\u00e6ner). <\/p>\n
