ABSTRACT:
A system to transfer electronic information includes reception of a command to transmit a file of electronic information. In response to the received command, the file of electronic information is automatically copied to create a copied file of electronic information, the copied file is transmitted, and the file of electronic information is rendered unusable. By rendering the file of electronic information unusable after copying the file, no additional usable copies of the file will remain. As a result, a degree of protection is provided to any copyright interest in the electronic information embodied therein.
