Integrated tracking of multi-authentication among web services

A computer system for sharing network authentication comprising:

• a first computer, wherein the first computer comprises a memory and a processor;
• executable software residing in the first computer memory, wherein the software is operative with the first computer processor to:
• receive login information from a user logging into the first computer, wherein the login information comprises an identification of the user;
• transmit the login information to an authentication computer, wherein the authentication computer comprises a memory and a processor;
• receive a user session key and a second site's site key from the authentication site;
• and
• transmit the user session key and the second site's site key to the user;
• a second computer, wherein the second computer comprises a memory and a processor;
• executable software residing in the second computer memory, wherein the software is operative with the second computer processor to:
• receive the user session key from the user logging into the second computer;
• transmit the user session key to the authentication computer;
• receive the second site's site a key from the authentication site;
• and
• transmit the second site's site key to the user;
• and
• executable software residing in the authentication computer memory, wherein the software is operative with the authentication computer processor to:
• receive the login information from the user logging into the first computer;
• verify the login information;
• transmit the user session key and the second site's site key to the first computer, wherein the user session key and the second site's site key are generated at the authentication site;
• receive the user session key from the user logging into the second computer;
• verify the user session key;
• and
• transmit the second site's site key to the second computer.

A computer system for sharing network authentication comprising:

• an authentication computer, wherein the computer comprises a memory and a processor;
• and
• executable software residing in the computer memory wherein the software is operative with the processor to:
• receive login information at an authentication site for a user logging into a first site, wherein the login information comprises an identification of the user;
• verify the login information at the authentication site;
• transmit a user session key and a second site's site key to the verified user through the first site, wherein the user session key and the second site's site key are generated at the authentication site;
• receive the user session key at the authentication site for the user logging into a second site;
• verify the user session key from the user at the authentication site;
• and
• transmit the second site's site key to the verified user through the second site.

A computer data signal embodied in a digital data stream for sharing network authentication, wherein the computer data signal is generated by a method comprising the steps of:

• receiving login information at an authentication site for a user logging into a first site, wherein the login information comprises an identification of the user;
• verifying the login information at the authentication site;
• transmitting a user session key and a second site's site key to the verified user through the first site, wherein the user session key and the second site's site key are generated at the authentication site;
• receiving the user session key at the authentication site for the user logging into a second site;
• verifying the user session key from the user at the authentication site;
• and
• transmitting the second site's site key to the verified user through the second site.
