Re: NSA whistleblower Edward Snowden: 'I don't want to live in a society that does these sort of things'
Unfortunately, packets sniffing using DPI is already commonplace among ISPs; they use it for example to (but not confined to) throttling back P2P traffic to prevent congestion;
Leveraging existing systems in place to build profiles for targeted advertisement sold to third parties is only a logical extension of this.
Some of the simplest data analysis your ISP could do, which does not require DPI, would be just to look at their DNS server logs (as most customers use the DNS provided by their ISP). One step above this, using DPI, and you can collect statistics about actual http requests (as DNS replies get cached locally on the client, it does not map 1:1 to the amount of page visits). Yet another step above, and you can do content analysis on all plain-text data send/received.
I'd love to be completely wrong on this, so please tell me where information in my post is incorrect. If you are in the position to tell us a bit more on which content gets analyzed by your 'big data' toolkit, that would also be very interesting.
