I Chrome 76 blev en bagd\u00f8r lukket<\/a><\/noindex> i implementeringen af FileSystem API, der gjorde det muligt for webapplikationer at bestemme, om inkognito-tilstand var aktiv. Fra og med Chrome 76 er der i stedet for at blokere adgangen til FileSystem API, som tidligere blev brugt som et tegn p\u00e5 aktivering af inkognito-tilstand, stoppet med at begr\u00e6nse FileSystem API, men \u00e6ndringerne blev renset efter sessionen. Det viste sig, at den nye implementering har<\/a><\/noindex> mangler, der som tidligere g\u00f8r det muligt at bestemme aktiviteten af inkognito-tilstand.<\/p>\n

Essensen af problemet er, at sessionen med FileSystem API i inkognito-tilstand er midlertidig, og data gemmes ikke p\u00e5 disken, men holdes i RAM. Derfor, ved at m\u00e5le<\/a><\/noindex> tiden for at gemme data via FileSystem API og de afvigelser, der opst\u00e5r (n\u00e5r der gemmes i RAM, registreres konstant karakteristika, mens forsinkelserne \u00e6ndres ved skrivning p\u00e5 disken), kan man ret sikkert bed\u00f8mme, om den viste side er i inkognito-tilstand eller ej. Ulempen ved metoden er, at det er en ret langvarig proces at m\u00e5le afvigelser, som kan tage omkring et minut (demonstration<\/a><\/noindex>). <\/p>\n

Samtidig forbliver der endnu en uopdaget problemet<\/a><\/noindex>, som g\u00f8r det muligt at vurdere aktiviteten af inkognito-tilstand baseret p\u00e5 vurdering af de begr\u00e6nsninger, der anvendes gennem API'en Quota Management<\/a><\/noindex>. For det midlertidige lager, der anvendes i inkognito-tilstand, er der fastsat andre gr\u00e6nser end ved fuld opbevaring p\u00e5 disken.<\/p>\n

Husk, at websteder, der er interesseret i at bestemme inkognito-tilstand, ofte arbejder p\u00e5 en model med fuld adgang mod betaling (paywall). For at tiltr\u00e6kke nyt publikum giver s\u00e5danne websteder nye brugere gratis fuld adgang i en kort periode, hvilket aktivt udnyttes til at omg\u00e5 paywall. Den nemmeste m\u00e5de at f\u00e5 adgang til betalt indhold i s\u00e5danne systemer er at bruge inkognito-tilstand, hvor webstedet tror, at brugeren \u00e5bner siden for f\u00f8rste gang. Udgiverne er ikke tilfredse med denne adf\u00e6rd, og derfor har de aktivt udnyttet den relaterede bagd\u00f8r i FileSystem API til at kr\u00e6ve, at inkognito-tilstand sl\u00e5s fra for at forts\u00e6tte visningen.<\/p>\n
