Hmm, it comes pretty close to
BitLaundryBitLaundry Explanation
BitLaundry is designed to help unlink accounts from each other. It does that by providing a well-known, and hopefully popular service. Here's how it works:
1. Imagine that Alice wishes to send BitCoins to Bob.
2. Bob, sadly, is not well liked. Alice would rather not have anyone know that she sent Bob BitCoins.
3. So, Alice puts Bob's address in the form at BitLaundry.
4. Alice gets a one-time-use address from BitLaundry.
5. Alice sends the money to that address.
6. BitLaundry sends money out to recipients every 30 minutes.
7. (But, it doesn't send out Alice's money immediately, that might be suspicious..)
8. So, a random number of 30 minute segments later, BitLaundry sends the money out to Bob.
9. BitLaundry then deletes the database link between the one-time-use address and Bob.
10. Alice has sent money to BitLaundry, but people do this all the time. She's one of many.
11. BitLaundry has sent money to Bob, but BitLaundry has sent money out to a whole bunch of other people as well.
12. Alice and Bob are much less linked than they would have been otherwise.
But as I understand it, you can track Alice by looking at the block chain and look for the amount that Bob received by BitLaundry.
Then you check which address sent this amount to BitLaundry (probably one of the one-time-use addresses from step 4) and then check which address sended that amount to the one-time-use address.
Is that correct ?
