Investigation questions effectiveness of App Tracking Transparency

Last May, the iOS 14.5 update enabled the launch ofl’App Tracking Transparency. This is a major change in terms of personal data protection. So, if an application collects and transmits information to third parties, it must inform the user. The latter is then able to accept or refuse this monitoring.

The measure greatly displeased companies like Facebook and Snap whose business model is based above all on the collection of our data for advertising targeting purposes. According to an investigation byFinancial Times, the latter would nevertheless have found a flaw in this new tool.

Data recovered, even if the user disagrees

The British newspaper thus indicates that developers are still able to collect iPhone signals at the user level if the latter are “anonymized and aggregated”, rather than linked to specific user groups. Therefore, a company like Snap is able to share the data of its 306 million users, and even of those who requested tracking, indicate our colleagues.

Concretely, this is therefore an interpretation of the message from the Apple brand which indicated that applications cannot recover data from a single device to target a single person. From then on, tracking of a phone's signals at a group level could be authorized.

That said, there is no indication that Apple has given its consent to the developers and for the moment, the company has not wished to respond to theFinancial Times. Note that this is not the first time that the effectiveness of App Tracking Transparency has been called into question. This summer we returned in particular to another investigation carried out by theWashington Post.
