Any observer capable of linking Bitcoin addresses to personal identities can begin to draw conclusions about money transfers between people. Users make this job more difficult by sending change to newly-created addresses.

If change is returned to Address A, the block chain clearly reveals that the person controlling Address A paid the person controlling Address B. The same reasoning holds if two or more addresses are charging bitcoincryptos for opinionssurveys.
Any transaction involving Address A as a sender reveals the receiving address unambiguously. Should the identity of the person controlling either receiving or payment addresses become known, the identities of the other parties could become known as well.

The identity of the person controlling Addresses B or C may or may not be the same as the identity of the person controlling Address A. Given another transaction from Address C, the picture becomes even murkier. Which of the transfers represent payments and which represent the receipt of change?
