An Internet-based system that allows you to transfer funds anonymously. As with credit cards, eCash was free for users, while sellers paid a fee. Due to security concerns, eCash is still more an idea and less of an actual payment system.


ECash uses blind signatures (a type of digital signature where the content of the message can not be seen before it is signed) so it can not make a link between withdrawal and spend transactions. The system was used by a bank in the United States, Mark Twain Bank; However, the system was disbanded in 1997 after the bank was bought by Mercantile Bank. ECash was a trademark of DigiCash, a firm that filed for bankruptcy in 1998 and was sold to eCash Technologies. ECash Technologies was acquired in 2002 by InfoSpace.

Electronic payment systems come in many forms, including digital checks, debit cards, credit cards and stored value cards. The usual security features for these systems are privacy (protection against eavesdropping), authenticity (providing user identification and message integrity) and non-repudiation (prevention of denial after having made a transaction).

The type of electronic payment system focused on this document is effective electronic. As its name implies, electronic money is an attempt to build an electronic payment system modeled after our paper cash system. Paper money has characteristics such as: portable (easy to carry), recognizable (as legal tender), therefore easily acceptable, transferable (without the participation of the financial network), anonymous (no record of where it is spent The money) who has spent the money) and has the ability to make "change". Electronic cash designers focused on preserving the characteristics of untraceability and anonymity. Therefore, electronic cash is defined as an electronic payment system that provides, in addition to previous security features, the properties of the anonymity of the user and non-traceability of payments.

Ecash was conceived by David Chaum as an anonymous cryptographic electronic money or electronic cash system in 1983. It was made through his Digicash company and used as a micropayment system in a US bank. From 1995 to 1998.
