V Chrome 76 je bila zaprta<\/a><\/noindex> vrata v implementaciji FileSystem API, ki omogo\u010da dolo\u010ditev uporabe na\u010dina inkognito iz web-aplikacije. Za\u010deli so s Chrome 76 namesto blokiranja dostopa do FileSystem API, ki je bil uporabljen kot znak aktivnosti na\u010dina inkognito, brskalnik prenehal omejevati FileSystem API, ampak je o\u010distil vnose po seji. Izkazalo se je, da nova implementacija ima<\/a><\/noindex> pomanjkljivosti, ki omogo\u010dajo, da se kot prej dolo\u010da aktivnost na\u010dina inkognito.<\/p>\n

Bistvo problema je, da je seansa z FileSystem API v na\u010dinu inkognito za\u010dasna, podatki pa se ne shranijo na disk, temve\u010d ostanejo v operativni pomnilnik. Posledi\u010dno, merjenje<\/a><\/noindex> \u010dasa shranjevanja podatkov preko FileSystem API in nastale odstopanja (pri shranjevanju v RAM se bele\u017eijo stalne zna\u010dilnosti, medtem ko se pri pisanju na disk zakasnitve spreminjajo) omogo\u010da razmeroma zanesljivo ugotavljanje, ali se stran gleda v na\u010dinu inkognito ali ne. Slabost metode je precej dolg postopek merjenja odstopanj, ki lahko traja pribli\u017eno minuto (demonstracija<\/a><\/noindex>). <\/p>\n

Ob tem v Chrome 76 ostaja \u0161e ena te\u017eava<\/a><\/noindex>, ki omogo\u010da presojanje aktivnosti na\u010dina inkognito na podlagi ocene nastavljenih omejitev preko API Quota Management<\/a><\/noindex>. Za za\u010dasno shrambo, ki se uporablja v na\u010dinu inkognito, so nastavljene druga\u010dne omejitve kot pri polnem shranjevanju na disk.<\/p>\n

Spomnimo, da so v definiciji na\u010dina inkognito zainteresirane spletne strani, ki delujejo po modelu zagotavljanja popolnega dostopa za pla\u010dilo (paywall). Za privabljanje nove publike take strani zagotavljajo novim uporabnikom za dolo\u010den \u010das prikazni neposredni dostop, ki ga aktivno uporabljajo za obhod paywalla. Najpreprostej\u0161i na\u010din za dostop do pla\u010dljive vsebine v takih sistemih je uporaba na\u010dina inkognito, pri \u010demer spletna stran misli, da je uporabnik odprl stran prvi\u010d. Izdajatelje to obna\u0161anje ne zadovoljuje, zato so aktivno uporabljali z FileSystem API povezane vrzeli za izpolnitev zahteve o izklopu na\u010dina inkognito za nadaljevanje ogledovanja.<\/p>\n
