The technique works by "exploiting small, microscopic deviations in device hardware: clock skews." In practice, Kohno's paper says, his techniques "exploit the fact that most modern TCP stacks implement the TCP timestamps option from RFC 1323 whereby, for performance purposes, each party in a TCP flow includes information about its perception of time in each outgoing packet. A fingerprinter can use the information contained within the TCP headers to estimate a device's clock skew and thereby fingerprint a physical device."Wow.
listen. think. act.
And get started by watching Bono's speech to this year's TED conference. The whole address is about 30 minutes. Highly recommended.
back into the flow
I've been really busy the last few days, and blogging has suffered. Oh well. I expect this will continue to happen for the foreseeable future. :)
I am really enjoying the weather here. Truly fantastic. One thing I miss, though, is Webvan, which was really great. I have to try out Safeway and see how it goes--otherwise shopping is kind of a pain since I don't have a car yet. But, you know, biking back and forth to the office actually makes up for it. Particularly in this weather.
Did I mention I'm enjoying the weather? :)
new mobibot, new GoogleME
Erik has released a new version of GoogleME and a new version of mobibot. Very cool. I still don't have a local phone, but once I do I'll actually be able to use the local features of GoogleME (which weren't very useful in Ireland :)). Also, mobibot is now uploading directly to del.icio.us, which is a great example of the use of the delicious API. I still have to make some time to play with that myself!
