The websites εξακολουθούν να είναι σε θέση να εντοπίζουν πότε ένας επισκέπτης χρησιμοποιεί τη λειτουργία ανώνυμης περιήγησης στον chrome (private browsing), despite Google's efforts last year to fix it.
There are many different reasons why webmasters want to block users from using incognito browsing.
Για παράδειγμα, ορισμένοι χρήστες χρησιμοποιούν την ανώνυμη περιήγηση για παράκαμψη payments περιεχομένου. Επιπλέον, οι τρέχουσες λειτουργίες ανώνυμης περιήγησης (ιδιωτική περιήγηση) στα περισσότερα προγράμματα περιήγησης αποστέλλονται επίσης με δυνατότητες κατά της παρακολούθησης που εμποδίζουν τους ιστότοπους να παρακολουθούν και να δημιουργούν έσοδα από την επισκεψιμότητά τους.
Both of the above issues that appear with the use of private browsing result in immediate financial losses on the websites.
In early 2019, Google decided to stop these scripts. THE Chrome 76, released in July 2019, included an update that prevented websites from using the FileSystem API to detect when a user use Chrome's regular browsing mode or its incognito browsing mode.
Before Chrome version 76, the FileSystem API was simply not available in incognito mode, and webmasters could simply send a query to this API to find out whether a user was using incognito mode or not. With Chrome 76, Google enabled the FileSystem API for incognito mode by making the previous scripts detections completely useless. However, this update contained errors.
Google did not fully enable the FileSystem API, but set a limit on the size of storage space that anonymous browsers could access at 120 MB.
It took developers less than a weekteam after the release of Chrome 76 to find out what was going on and develop scripts that probed the FileSystem API to determine how much storage a site could access. So they could indirectly detect whether a user is using the incognito mode or not.
Two different scripts were released in August 2019 [1, 2] and one of them even exists on the New York Times website, confirming how popular these scripts are with web content publishers.
Answering a question from Bleeping Computer, Google promised in August 2019 to fix the bypass and block anonymous browsing.
However, nine months later, it is still possible to detect anonymous browsing in Chrome and all other Chromium-based browsers, such as Edge, Opera, Vivaldi and Brave.
Προς το παρόν, δεν γνωρίζουμε κάποια ημερομηνία για το πότε θα κυκλοφορήσει ένα patch που επιδιορθώνει το ζήτημα, αλλά η Google μπορεί να ενδιαφέρεται περισσότερο από ποτέ για την resolution αυτού του θέματος.
On Tuesday, the company accused that it was secretly monitoring users, even in incognito mode.
Please note that blocking incognito browsing will not prevent advertisers from tracking users, as both administrators and advertisers will continue to see information such as IP addresses and other traffic data. However, it will help Google gain some users who are interested in their privacy.
