Privacy International: Facebook is watching you & without an account

The British company Privacy revealed on Sunday at 35 Chaos Communication Congress how app developers deliver data to Facebook, even if users are not Facebook users.

The company made a for that matter, with tests on 34 Android apps that have between 10 and 500 million users, and says it is "highly concerned" about how user data is being "exploited" in the back-end systems of Facebook and Google.

Privacy International found that 23 of the apps tested sent data to Facebook (data that tells the social network that a user opened or closed a specific μαζί με πληροφορίες για την συσκευή, ρυθμίσεις γλώσσας και ζώνης ώρας). Οι εφαρμογές έστελναν επίσης το αναγνωριστικό διαφήμισης της Google του χρήστη, το οποίο επιτρέπει στις εταιρείες παρακολούθησης να πραγματοποιούν εύκολα αντιστοίχιση στα προφίλ των χρηστών.

By doing a special treatment in the Kayak travel application, the researchers discovered that they provided Facebook data with every search within the application: search time, departure and arrival city, airport and date, number and category of tickets.

Privacy International pointed out that this behavior was repeated regardless of whether the user had disconnected from Facebook or had no social networking account.

"Facebook offers analytics and advertising services to application developers, which help them get centralized information on how people handle their applications, which is a common practice for many companies," Facebook said in a privacy statement. International.

Facebook also highlighted the Clear History feature, first announced in May during the scandal Cambridge Analytica, as a means of handling complaints from Privacy International.

Privacy International also looked at how Facebook's policies compare to Europe's GDPR requirements and design to minimize .

However, with applications transferring data to Facebook before the user can use the application, Privacy International said there are many questions about whether there is any legal basis for data transfer.

In October, we passed social network announced that unknowns had combined three bugs to access million token IDs of 30 token.
