System and method for secure electronic fund transfers

Abstract

A system and method for allowing simplified electronic transfer of funds in files subject to sender-defined access constraints. In one aspect of the system and method, a digital currency file is transmitted as an attachment to an electronic message. The sender of the digital currency file defines the level of security associated with the file, i.e., what the recipient must provide to access the funds.
