Google developing eavesdropping software

Audio ‘fingerprint’ for content relevant ads

Comment: The first thing that came out of our mouths when we heard that Google is working on a system that listens to what’s on your TV playing in the background, and then serves you relevant adverts, was “that’s cool, but dangerous”.

The idea appeared in Technology Review citing Peter Norvig, director of research at Google, who says these ideas will show up eventually in real Google products – sooner rather than later.

The idea is to use the existing PC microphone to listen to whatever is heard in the background, be it music, your phone going off or the TV turned down. The PC then identifies it, using fingerprinting, and then shows you relevant content, whether that’s adverts or search results, or a chat room on the subject.

And, of course, we wouldn?¢‚Ǩ‚Ñ¢t put it past Google to store that information away, along with the search terms it keeps that you’ve used, and the web pages you have visited, to help it create a personalised profile that feeds you just the right kind of adverts/content. And given that it is trying to develop alternative approaches to TV advertising, it could go the extra step and help send “content relevant” advertising to your TV as well.

We suspect that such a world would be rather eerie, with a constant feeling of d?ɬ©j?ɬ† vu every time anyone watched TV.

Technology Review said Google talked about this software in Europe last June, and that it breaks sound into a five-second snippets to pick out audio from a TV, reducing the snippet to a digital “fingerprint”, which it matches on an internet server.
