ECASH AND PRIVACY One of the unique features of ecash is payer anonymity. When paying with ecash the identity of the payer is not revealed automatically. This way the payer stays in control of information about himself. During a payment a payer can of course identify himself, but only when he chooses so. Ecash offers one-sided anonymity; when clearing a transaction the payee is identified by the bank. (according to http://www.digicash.com/ecash/about.html) But what about Okamoto and Ohta's digital cash scheme published in Crypto '91? It appears to be fully untraceable and transferable. Of course, I haven't heard of anyone trying to use this scheme (has it been broken?)
