Changing Threats To Privacy From Tia To Google (Blackhat 2010) by Moxie Marlinspike http://www.securitytube.net/video/1084

How many people here would be excited about a law that required everyone to carry a government mandated tracking device with them at all times? Probably very few people right, no-one's really excited about that. How many people here have a cell phone? Right, probably everybody in this room has a mobile phone. And so what is the difference really? A mobile phone is a tracking device that reports its position over an insecure protocol to a few telecommunications companies that are required by law to reveal that information to eavesdroppers and governments worldwide. So what's the difference? Choice. This is the difference. You choose to carry a cell phone, whereas you would be forced to carry a tracking device.

Well I have a mobile phone. Never in my wildest dreams did I think I would have a mobile phone, why would I want one: it's a mobile tracking device, it communicates over an insecure protocol, it's potentially a mobile bug. And yet I have one. So did I choose to have a mobile phone? Maybe.

I think if you look at the way that people tend to organise in groups and communities, there are often informal communications networks that bind them together, that allow them to communicate, make plans, coordinate activities. If you introduce something like the GSM cellular network to this group, and if I start using it, I am subject to something that is very well known called the No Network Effect. If I am the only one with a cell phone it's really not worth very much. The value of the network is in the number of people that are connected to it and that if I'm the only one I can't really communicate with anyone.

However if I somehow manage to get everyone to start using my communications network it becomes very effective and very valuable. But there is an interesting side effect, which is that the old informal mechanisms people use to communicate and to collaborate disappear, that they are destroyed by the introduction of technology. The technology actually changes the social fabric of how people communicate and coordinate. Mobile phones, there are many obvious examples. People used to make plans, they would say: "I'll meet you on this street corner at this time on this day and, you know, we'll do something" and now people say "I'll call you when I'm getting off work" or "I'll text you" and if you don't have a mobile phone you can't really participate in this type of organisation and you begin to find yourself kind of alone. Because if I now make a choice not to be a part of this cellular network, there is sort of an interesting thing where once again I am subject to the no network effect. The network that used to exist, the informal communications channels, has been destroyed.

So yes, I made a choice to have a mobile phone, but what kind of choice did I make? I think this is sort of an interesting phenomenon. What happens is a choice is introduced; it starts as a very simple choice: the choice of whether or not to have a mobile phone, a simple piece of technology. But slowly things happen to expand the scope of that choice until eventually it's so big as to encompass not just whether you have a mobile phone or not but whether you want to be a part of society. In some ways the choice to have a mobile phone today has become not necessarily just whether you have a piece of consumer electronics in your pocket but whether or not you are even a part of society, and that's a much bigger choice. Maybe not one that we should have to make, or at least maybe one that isn't really a choice at all.

That is it right there.

The only answer is the same technology without the bad side of it.

Mobile phones that do not track you, that governments can not track.

A Facebook alternative like Diaspora, except much better and as popular as Facebook.

We are not going to quit mobile phones and social media, but we have to strip their bad side from them. That may involve non-profit mobile phone manufactures, open source social media, who knows exactly what. But I know that technologically it is possible, now we have implement it and use it.

> Mobile phones that do not track you,

The pragmatist in me wants to call that a pipe dream. Phones that work on the cell system that don't track you are an oxymoron. It would require a ground up reimplementation of phones. The best case I can see is burner sim cards for smartphones with all the data encrypted and some non-skype popular voip platform. Even if someone built all this you'd still be tracked while you used the phone.

You could start talking about mesh networks or public free wifi to improve some of those problems but any technically realistic solution relies on government supporting things they inherently dislike and popular support for "terrorist helping" technology (which the public doesn't care about until a local power group starts using surveillance to kill/torture a lot of them)

This post breaks line-wrapping for the whole page.

I suspect that long string of italicized text is to blame. Please remove the italics (which also make the words hard to read).

Ah, sorry about that. The post is too old for me to edit now.
