Patent Images
1. A method of authenticating a user on a network, comprising:
- receiving, by a security server, a request of a network site to have the user authenticated;
generating, by the security server, a one-time-password, wherein the one-time-password is generated as a function of a secret shared by the security server and the network site but not known to the user, and wherein the shared secret comprises a predetermined value agreed upon by both the security server and the network site to be used for all users utilizing the enterprise; and
transmitting over the network, by the security server to a remotely located first network device of the user, the one-time-password for entry by the user on a second network device of the user for subsequent verification by the network site to thereby authenticate the user.

Abstract
To provide a user signature on a network transaction, a security server receives transaction information representing a transaction between a network user and a network site, such as a website, directly from the network site. The security server calculates a one-time-password based on the received transaction information and a secret shared by the security server and the network site, but not by the user. The security server transmits the calculated one-time-password for application as the user'"'"'s signature on the transaction. The one-time-password is independently calculable by the network site based on the shared secret.

11. A method of authenticating a user on a network site, comprising:
-
transmitting, by the network site directly to a security server, a request to have the user authenticated; receiving, by a network page associated with the network site from a network device of the user, a one-time-password for authentication, wherein; the one-time-password is generated and transmitted over a network, by the security server to the network device of the user for entry by the user onto the network page using another user network device; the network device of the user is remotely located from the security server; the one-time-password is generated as a function of a secret shared by the security server and the network site but not known to the user; and the secret shared by the security server and the network site comprises a predetermined value agreed upon by both the security server and the network site to be used for all users utilizing the enterprise; receiving, by the network site, the one-time-password; receiving second information directly from the security server; and authenticating, by the network site, the user based on the second information. - View Dependent Claims (12, 13, 14, 15)

16. A method of authenticating a user on a network site, comprising:
-
transmitting, by the network site directly to a security server, a request to have the user authenticated using a one-time password to be generated by the security server, wherein; the one-time-password is generated as a function of a secret shared by the security server and the network site but not known to the user; and the secret shared by the security server and the network site comprises a predetermined value agreed upon by both the security server and the network site to be used for all users utilizing the enterprise; receiving, by a network page associated with the network site from a network device of the user, the one-time-password generated by the security server, wherein the one-time-password is transmitted over a network, by the security server to the network device of the user for entry by the user onto the network page using another user network device, wherein the network device of the user is remotely located from the security server; and authenticating, by the network site, the user based on the one-time-password. - View Dependent Claims (17, 18, 19, 20)
