Is Comcast Intercepting Packets?

nihilist_1137 writes: "According this page, comcast is intercepting your packets to gain knowledge of your whereabouts and then reselling it to marketers." According to the linked message, "This allows them to not only log all http requests, but to also log the response. Maybe they want to profile their customer browsing history for subsidiaries or resale to marketers. Maybe they want to do their part in The War on Freedom. Maybe they just want passwords to porn sites. Apparently they aren't using it to maximize bandwidth, because it's not configured to serve cached data."

Qwest, Sprint, MCI and thousands of other businesses and sometimes counties own the phone lines and the switches. If I make a call, EVEN Out of country, and Go from Qwest owned phone lines to your Canada owned phone lines, Qwest and the Canadian owned company have to reach a agreement on what to charge for the usage, BY THE SECOND.
      Third party companies house these charges. The company Qwest uses is called Telview, found at http://www.telveiw.com; it's called a TARIFF library, Telview makes their money by handling these charges and selling them to telecoms. EVERY digital switch in the world uses some system like this, or in conjunction with.
      Now the database in play comes in not to track who you are calling so much. But because once your voice packet leaves Qwest lines it is not their propriety anymore and someone has to pay for the usage. Thus MCI can say you as a Qwest user, used X amount of trunk access on their lines, and charge Qwest X amount of dollars for those seconds. Qwest logs roughly about 140+ million phone calls a day, their system is considered by the FCC to be the definitively correct system, In audit type disputes The FCC will even use Qwest records as a third party advisor, because we track EVERYTHING, even all of the other telecoms, and almost all in the world. We just made it into Europe last summer. Anyway these millions and millions of minutes are charged at as low as -5 cent a minute to crazy 15+ cents a minute. It goes negative because of anti-monopoly issues regarding start up telecoms. Seconds are rounded and tracked to the nearest thousandth. On Qwest's system, an audit system HAS to be in place, this is part of FCC regulation crap, not to mention allows the FCC to more or less do their job. Generally that database doesn't have names in it. But the billing database that does have all your names in it if you subscriber to Qwest, private or not.... is a simple sql call away, it quite latterly lives in the same server farm... No stored procedures can link the two databases by LAW. Unless a search warrant is in place. Then with the officer there, we can link them. But the link has to be deleted also under the officer's super vision. Your records are tracked as up to two years, then deleted off, one month at a time. So two years ago to last month, we have no clue of whom you called, and are really glad to have a little more space.
      The rule is if you can't use a blue box on your phone line, then you are traceable down to that specific phone. Digital Switch = Trackable.

      p.s. For those who wonder, The system is Called NTU, Network Transaction Usage. We use Perl to gather data off the switches, not every switch is alike, including the os they run and the data needs to be parsed for the database. A HP/UX demon is used to process rules, and sort out how they should be poked into the database. While an oracle database floating on 36 partitions in a huge raid system is used to house the data while it lives.

      You can therefore not expect privacy of the data from anyone who is responsible for routing.

      I most certainly can. Routing packets by reading the IP headers which I put on them for the routers' benefit is one thing. Setting up a box to read through the data in the packet is quite another.

      The fact that routers only look at the IP headers by default and that you'd have to install special equipment and/or software to record the application-layer data is a pretty strong indication that the distinction between the IP header and the data is meaningful.

      It's worth noting that laws apply to people (and corporations), not machines. It's not illegal for a router or the phone system to do anything. It's when the ISP installs some equipment to monitor private communications (for purposes other than those explicitly allowed) or when someone looks at/listens to those communications or discloses their contents to someone else that the law applies.

    Btw. this is not limited to http. anonymous ftp, and the most common streaming media protocols can be redirected the same way and cached also.
    The difference with the streaming protocols is that the host server not always allows it. But if it does then the cache will report back to the streaming server how many clients it has behind it. If it's a live stream, the cache won't cache it but do a spliting of the screen. The host server should be able to view this as they have many connections on their server but low bandwidth usage.
