It looks like deep packet inspection comparing against hashes of known violating content that constantly updates.  Even the patent seems obvious as I had that idea circling in my head how they would do that as soon as I read the headline of this article.   This is not innovative.  AT&T must feel comfortable with their monopoly status to screw over customers like this.  I can’t imagine keeping hash tables of content violations accurate will be very easy.   Add to that the security implications of hackers infecting these tables with bogus hashes and you have a recipe for disaster.  Only a company with monopoly status can take such a risk because many of their “customers” have no other choice for Internet access.

Verizon Wireless’ marketing literature acknowledges that it sells “mobile-usage data that offers insights on the mobile-device habits of an audience, including URL visits, app downloads and usage.” (Not all carriers do: Google guarantees that its proof-of-concept Google Fiber project “will not engage in deep packet inspection” except when necessary to fend off network attacks.)
