Ultrasonic Ad-Tracking

tinnitusDie neueste Idee der Advertising-Scam-Artists: Werbespots und Banner, in denen Ultraschall-Sounds laufen, die wiederum von Geräten erkannt werden, auf denen schließlich ein Cookie gesetzt wird, um das Verhalten der User zu tracken. Adblocking hilft also seit neuestem auch gegen Tinnitus.

Privacy advocates are warning federal authorities of a new threat that uses inaudible, high-frequency sounds to surreptitiously track a person's online behavior across a range of devices, including phones, TVs, tablets, and computers.

The ultrasonic pitches are embedded into TV commercials or are played when a user encounters an ad displayed in a computer browser. While the sound can't be heard by the human ear, nearby tablets and smartphones can detect it. When they do, browser cookies can now pair a single user to multiple devices and keep track of what TV commercials the person sees, how long the person watches the ads, and whether the person acts on the ads by doing a Web search or buying a product.

Ich würde behaupten, hierbei handelt es sich um eine völlig neue Klasse von Dark Pattern Design („A Dark Pattern is a user interface that has been carefully crafted to trick users into doing things, such as buying insurance with their purchase or signing up for recurring bills“).
