Wanted to pass along a link to CA’s Security Advisor Research Blog, where they conducted an experiment to see what personal information Facebook was collecting by way of its controversial Beacon system, and how. You may recall that Facebook was using Beacon to send out lists of purchases made by Facebook users at certain online retailers to thier Facebook friends, unless they opted out of the program. Turns out that in this experiment, data was still being collected on this CA user even though he had opted out and was not logged in. An intriguing correspondence between he and a Facebook customer support rep is included and is worth a read.
