"You should assume your IP address can be associated with you.." -Gavin Anderson

[BitDreams]

With the Bitcoin protocol, could I demand that all entities enquiring into my IP access that data only through my personal multi-signature (or authorized legal/agent) release? In other words, I get a 'you are being snooped message' - again, hidden only through legal means and well documented in the blockchain available for audit. An ultimate goal of mine would be to receive a micro-payment for something as common as a website tracking cookie and gain royalty upon its use. Doesn't matter if we think Google will do it or not, someone will and when they do... Another example, red-light cameras: Pictures go into a crypto/blockchain transaction, access is allowable for brief periods using location protected hardware (leaves the building and it automatically wipes/disables).

So someone buys the right to visually inspect that picture and i am in it. I've got copyright and also protection, and if I wasn't part of the crime (no crime, no reason to be buying up my picture, right?), then i've earned a Satoshi and was informed of surveillance. For every invasion of privacy from bitcoin I could probably come up with 10 protections or ownerships of privacy. Cameras? You take a picture in public? My phone is informed as you've broadcast your actions to the local mesh. This can be done with hardware. Off the grid and on a murky network? Ok, but you'll find your social passport shut down as you traffic in public places. Today I feel if I met a Sci-Fi B grade movie producer I would grab and shake them till they hear me, "Here's Bitcoin 2025, I've got the first 10 episodes"

So much is on the table. I don't think that it can be controlled, I believe it will evolve.

Bitcoin is anonymous because of the sheer number of transactions that take too long to figure out.  If you get on somebody's list, they can figure you out.

[LiteCoinGuy]

There are a number of ways to mask where a TX originated from:

Tor
Public WiFi
Using blockchain to push a signed TX for you
running a full node and having a light client only connect to that node

Zerocoin.

This is not valid with Dynamic IP internet connections, like the connection I've right now.

Even with a dynamic IP address your identity can still be found.

Your ISP will keep logs of who is assigned what IP address at what times.

Any more information on this? My only sources come from talking to ISP support reps but they've always told me "due to the dynamic nature of allocating IPs" they can't confirm who the owner is, which to me sounds like BS because I'm sure all ISPs have to have rules in place so they can identify customers in the case of abuse.

The root of that crime is stealing anothers connection. That's the best spoof. Now if every packet were ever only shipped only with a sotoshi...

Its not too difficult to change your IP before broadcasting transactions or after broadcasting a transaction:

http://whatismyipaddress.com/change-ip - Requires you to insert a different MAC Addresses into your router homepage and unplug it for 5 mins.
https://www.privateinternetaccess.com/ - Bitcoin Accepted here!!

The issue here is the ISP has log which can point it to you if someone want to spy on you.

Changing IP doesn't solve the problem.

Good point, I actually did not even think about that. I was just thinking about the scenario if someone wanted to target valuable wallets, you would be able to change IP's so they could not target you.

Well if you're not doing anything shady or anything dirty you shouldn't have anything to worry about.

That's if you're on a private network like a locked wi-fi....

If you are using a VPN that you are certain does not keep logs then a transaction that you broadcast would be associated with the VPN's IP address and the absence of logs would make it difficult/impossible to link the VPN back to you.

Another solution would be to use TOR, as the transaction would be associated with the TOR exit node and I don't think there are any attacks on TOR that can be done to find someone's identity via TOR that can be done retroactively.

Why not just go to the library lol

[Cicero2.0]

Why not just go to the library lol

I don't want to go to the library every time I buy or send bitcoins. A VPN that doesn't keep logs is a much simpler solution.

You could really just use TOR to use bitcoin. As long as an adversary doesn't previously suspect that you are using bitcoin then you have basically 0 chance of any kind of timing attack

That is probably the simplest solution. I must admit I don't know how to connect my wallet to TOR but this discussion has inspired me to find out.

From the TOR Wiki

Run bitcoind with -proxy=127.0.0.1:9050 (or whatever your SocksPort is).
bitcoind will detect that you are using a proxy on 9050 and will force the "nolisten" flag. If you are not running tor on 9050, you need to set "nolisten" manually otherwise you will listen on your public IP and possibly reveal that you are running a node.

Still this is the type of thing that totally hurts the idea that bitcoin is really anonymous which is a big selling point on bitcoin.  Well better to know than not know I guess. But still I wasn't aware of this.

You need to have your wallet program connect to the Vidalia proxy via localhost (in proxy settings)

Or you could use blockchain.info and use TOR to connect to blockchain.info

[moriartybitcoin]

I wonder if this is true for electrum wallets?

Definitely NOT if you're running electrum with a VPN connected.

Also, IP addresses are NOT stored in the blockchain.

A) I don't want to go to the library every time I use bitcoins.

Also, they can track wallets. (I believe)
So you'd have to generate a new wallet AND use a crappy library internet connection. :I

[Realpra]

Well an IP is simply a number associated with a certain cable output. If said cable goes to your house.. well of course that IP can be tied to you, its basically an electronic address!

Add to that google, facebook and NSA datamining and I hope its not a surprise to anyone ever.
