No boundaries for Facebook data: third-party trackers abuse Facebook Login
How much of this is intentional on the part of the first-party site?<p>The article says:<p>> The following could indicate the first party’s awareness of the Facebook data access:<p>> 1) third-party initiates the Facebook login process instead of passively waiting for the login to happen; 2) third-party includes the unique App ID of the website it is embedded on. The seven scripts listed above neither initiate the login process, nor contain the app ID of the websites.<p>> Still, it is very hard to be certain about the exact relationship between the first parties and third parties.<p>But I can certainly imagine a situation where a site owner would inject a third-party analytics script into their site and have no problem with it including information from Facebook logins as part of the analytics data it collects.<p>After all, as a site owner why wouldn't I want my analytics dashboard (provided by a third-party) to include information like "percentage of visitors between the age of 18-25"? That seems like a useful thing to know, and the users who granted my site access to that info did so explicitly via a Facebook permissions prompt, so what's the issue?<p>The issue, of course, being that my site's user's data is now being handled by a third party. But I obviously had no problem with that when I decided to use a third-party analytics company in the first place; why would that change now?
