Abstract

A web site server is able to identify distinct users by using a unique identifier associated with each client computer system requesting access to a web site. The unique identifier comprises an Internet address, such as an Internet Protocol (IP) address, and a time value associated with each client computer system requesting access to the web site. On starting up a web browser, an application program or browser plug-in may synchronize the internal clock included with the client computer system with a global time standard. A web site server may determine the uniqueness of the client computer system by comparing unique identifier records of users accessing the web site. A user may be identified as distinct if no matching record exists in the database. Users privacy is also protected as the unique identifiers are erased when the client computer system'"'"'s user exits the web browser or powers down the computer.

Claims

1. A method comprising:

receiving, from a first computer;

a request to access a web site, and

a first Internet address and a first time value corresponding to said first computer;

determining whether a matching record for said first Internet address and said first time value exists in a database; and

identifying said first computer as a distinct user if said matching record does not exist in said database.

2. The method of claim 1, wherein said first time value is associated with a user-defined event.

3. The method of claim 2, wherein said user-defined event is a launch of a web browser software on said first computer.

4. The method of claim 1, wherein said first time value is generated by a time keeping device, wherein said time keeping device is configured to synchronize said first time value with a global time keeping standard clock.

5. The method of claim 1, wherein said first Internet address is an Internet Protocol (IP) address.

6. The method of claim 1, wherein the database is an object oriented database or a relational database.

7. The method of claim 1, wherein said first computer is a personal computer, a laptop computer, a notebook computer, an Internet-enabled cellular phone, an Internet-enabled personal digital assistant, or an Internet-enabled television.

8. A system, comprising:

a web site server computer system;

wherein the web site server is operable to;

receive from a first computer;

a request to access the web site, and

a first Internet address and a first time value corresponding to said first computer;

determine whether a matching record for said first Internet address and said first time value exists in a database; and

identify said first computer as a distinct user if said matching record does not exist in said database.

9. The system of claim 8, wherein said first time value is associated with a user-defined event.

10. The system of claim 9, wherein said user-defined event is a launch of a web browser software on said first computer.

11. The system of claim 8, wherein said first time value is generated by a time keeping device, wherein said time keeping device is configured to synchronize said first time value with a global time keeping standard clock.

12. The system of claim 8, wherein said first Internet address is an Internet Protocol (IP) address.

13. The system of claim 8, wherein the database is an object oriented database or a relational database.

14. The system of claim 8, wherein said first computer is a personal computer, a laptop computer, a notebook computer, an Internet-enabled cellular phone, an Internet-enabled personal digital assistant, or an Internet-enabled television.

15. A non-transitory memory medium, comprising program instructions, wherein the program instructions are executable by a computer system to implement a method of:

receiving, from a first computer;

a request to access a web site, and

a first Internet address and a first time value corresponding to said first computer;

determining whether a matching record for said first Internet address and said first time value exists in a database; and

identifying said first computer as a distinct user if said matching record does not exist in said database.

16. The memory medium of claim 15, wherein said first time value is associated with a user-defined event.

17. The memory medium of claim 16, wherein said user-defined event is a launch of a web browser software on said first computer.

18. The memory medium of claim 15, wherein said first time value is generated by a time keeping device, wherein said time keeping device is configured to synchronize said first time value with a global time keeping standard clock.

19. The memory medium of claim 15, wherein said first Internet address is an Internet Protocol (IP) address.

20. The memory medium of claim 15, wherein the database is an object oriented database or a relational database.
