In iOS 6, Apple implemented the Facebook APIs directly in the operating system for iDevices, simplifying the methods by which we can share content on the social network. In iOS 6, some levers were implemented that have the role of increasing user security, but it seems that if you are not very careful, you risk having them in your iDevice for nothing. Why am I saying this? Well, because yesterday I woke up out of the blue with an entry in the Calendar that was made by Facebook, but without me approving/rejecting any request to include that event in the calendar. Facebook basically published an event there for me that I don't know anything about, and whose name I don't even understand, but Facebook doesn't care and considers that, without my consent, it has to enter that entry there in the hope like I'm probably interested in her.
Visiting the new Privacy section of iOS I realized that the Calendars application does not have permissions set for the addition of content by third-party applications, but Apple took care to put this option right in the Facebook menu in the application Settings>Facebook. There you have the option to give Facebook access to Contacts, Calendar and the App Store, and the result is the one in the image above, that is, Facebook introduces entries into the Calendar by itself and then notifies you about their availability. Of course, deactivating access is possible, but iOS natively provides access and the problems don't stop here because Apple and Facebook have something more interesting prepared for us.
Never miss another birthday or get-together, since Facebook events are integrated into Calendar. And your Facebook friends' profile information is integrated into Contacts, so when they update an email address or phone number you automatically stay up to date. Now that's something to post about.
According to the information on Apple's website, Facebook scans the entire contact book, uploads the information to its own servers and then transfers it to other people's books. If you have set as public: phone number, email address or home address, etc., then your friends will see them directly in the Contacts application. Of course, there is the option to block these synchronizations, it is also in the menu Settings>Facebook, but by default the option is turned on, so if you ignore it, you'll wake up with calls from people you probably wouldn't even want to meet.
Basically what Apple did in iOS 6 is beyond the limits of normal, the options do not strengthen security but fragment the way you can protect yourself against uploading, without your consent, confidential data on Facebook servers and you must be very careful how you use everything. I will resume the subject in the fall when iOS 6 will be publicly released.
