Controlling access to electronically provided services |
| 摘要 |
<p>The security and integrity of card initiated transactions are improved by encrypting processes involved in such transactions and controlling access to the processes by developing decryption keys partially from data derived from a card presented by an intending user and partially from personal data supplied by the user. In an embodiment a hierarchy of security levels provides for users of different authority to access selected processes.</p> |
