System for authenticating access to online content referenced in hardcopy documents |
摘要 |
A system for controlling access to online content referenced in a hardcopy document. A user requesting access to online content available on a server responds to an authentication challenge from the server using a password mechanism printed in the hardcopy document. The password mechanism allows the user to identify a password for responding to an authentication request by the server. After authenticating the user, the server initiates a state change to enable subsequent access to the online content by the user with a different password that is also identified with the password mechanism.
