Anonymity and Transferability for an Electronic Bank Check Scheme

The advances in electronic commerce are replacing many of the paper processes involved in commercial transactions, from the contracting process to the electronic payment process. When we are dealing with payments of high value, bank transfers are preferred. But this kind of payments does not allow the anonymity of the parties involved in the commercial transaction. Electronic checks is a useful payment system for this kind of scenario, but the proposed solutions do not allow an anonymous transference as in paper-based checks. In this paper, we propose a new electronic bearer bank check scheme. The system allows the e-check to be transferred to any person by its owner without depositing it, and remaining anonymous in front of the bank.
