This should be interesting.
Mozilla has announced that they are starting a study and it involves figuring out how Facebook tracks you:
In a collaboration between journalists at The Markup and Mozilla researchers, this study seeks to map Facebook’s pixel tracking network and understand the kinds of information it collects on sites across the web. The Markup will use the data collected in this study to create investigative journalism around the kinds of information Facebook collects about you, and where.
And:
According to its own privacy policy, Facebook may collect information about you across the web even if you don’t have a Facebook account. One way Facebook performs this tracking is through a network of “pixels” that may be installed on many of the sites you visit. By joining this study, you will help Rally and The Markup investigate and report on where Facebook is tracking you and what kind of information they are collecting.
Now this is going to be very interesting to see what data Facebook is actually collecting as I am pretty sure that they are likely not being truthful about that. But I guess we’re about to find out. If you want to participate, you will need to download Mozilla Rally which is a browser extension that will collect data sent out by Facebook’s pixels as you browse across the web. Aside from that data, the extension also keeps track of the time spent on different web pages, the URLs that the browser visits, and more. Mozilla was quick to note in its announcement that the only data being exported from the extension will be de-identified, and not shared with any third parties besides the Markup’s reporters. And I believe that as I have a lot more trust in Mozilla than I do in Facebook.
Mozilla And Facebook Propose New Ad Tech That Preserves Your Privacy…. Think About That For A Moment
Posted in Commentary with tags Facebook, Mozilla, Privacy on February 12, 2022 by itnerdFrom the “I did not see this coming” department comes news that Meta/Facebook has teamed up with Mozilla to come up with new technology that can measure “conversions” from advertising while still preserving privacy. The proposed new technology is called Interoperable Private Attribution, or IPA:
IPA has two key privacy-preserving features. First, it uses Multi-Party Computation (MPC) to avoid allowing any single entity — websites, browser makers, or advertisers — to learn about user behavior. Mozilla has some experience with MPC systems as we’ve deployed Prio for privacy-preserving telemetry. Second, it is an aggregated system, which means that it produces results that cannot be linked to individual users. Together these features mean that IPA cannot be used to track or profile users.
IPA is designed to provide a lot of flexibility for advertising businesses in terms of how they use the system. Cross-device and cross-browser attribution options in IPA enable new and more robust attribution capabilities, while maintaining privacy. The IPA proposal aims to ensure that all sites benefit from these features with the match key concept, which allows smaller players to access the greater reach of entities to cross-device attribution.
My $0.02 worth goes something like this:
As far as I am concerned, this proposal is DOA. And Mozilla’s involvement really makes me think not as highly about Mozilla as I once did. If I were them, I would rethink my involvement with Facebook as that smells like a deal with the Devil.
