Abstract

An improved method and system for identifying individual users accessing a web site. A web site server is able to identify distinct users by using a unique identifier associated with each client computer system requesting access to the 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. The synchronized time value may be based on an event associated with the client computer system, such as the start of a web browser. 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. Multiple client computer systems having a common Internet address may be identified by using this method. 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 for identifying distinct users accessing a web site, the method comprising:

performing, by one or more hardware computer devices;

storing a plurality of records in a database, wherein each record of the plurality of records comprises an Internet address and a time value, and wherein each record of the plurality of records indicates a distinct user accessing said web site;

receiving a first Internet address and a first time value from a first computer accessing the web site, wherein the first time value corresponds to an event associated with the first computer;

identifying a distinct user corresponding to said first computer in response to determining that said first Internet address and said first time value does not match a second Internet address and a second time value of any individual record of the plurality of records in said database, wherein to improve accuracy of web hit counting the user is identified as a distinct user even when said first Internet address matches a particular Internet address of one or more of the records in said database that indicate accessing of said web site;

incrementing a hit counter by one in response to identifying the distinct user; and

adding to said database a new record comprising said first Internet address and said first time value in response to identifying the distinct user.

2. The method of claim 1, further comprising purging said database of records whose time value indicates presence in said database for a length of time exceeding a predetermined time threshold.

3. The method of claim 2, wherein a matching record does not exist in said database when a period of time in excess of that set by said predetermined time threshold has passed since said first computer last accessed said web site.

4. The method of claim 2, wherein said predetermined time threshold is approximately 30 minutes.

5. The method of claim 1, further comprising, in response to receiving a request from said first computer to access the web site, sending a request to said first computer for said first Internet address and said first time value corresponding to said first computer.

6. The method of claim 1, wherein said event associated with said first computer is a launch of an application program on said first computer.

7. The method of claim 1, wherein said event associated with said first computer is a launch of a web browser on said first computer.

8. A system for identifying a distinct computer user accessing a web site, the system comprising:

a web site server implemented on one or more hardware computer systems and configured to;

receive a first Internet address and a first time value from a first computer accessing the web site, wherein the first time value corresponds to an event associated with the first computer;

determine whether said first Internet address and said first time value matches a second Internet address and a second time value of any individual record of a plurality of records that exist in a database;

identify a distinct user corresponding to said first computer in response to determining that said first Internet address and said first time value does not match said second Internet address and said second time value of any individual record of the plurality of records that exist in said database, wherein to improve accuracy of web hit counting the user is identified as a distinct user even when said first Internet address matches a particular Internet address of one or more of the records in said database that indicate accessing of said web site;

incrementing a hit counter by one in response to identifying the distinct user; and

adding to said database a new record comprising said first Internet address and said first time value in response to identifying the distinct user.

9. The system of claim 8, wherein said first time value is synchronized with a global time standard.

10. The system of claim 8, wherein said web site server is further configured to dynamically update said database.

11. The system of claim 10, wherein to dynamically update said database said web site server is configured to add a record to said database each time said web site is accessed by a distinct computer user, said record comprising an Internet address and a time value obtained from a computer of said distinct user.

12. The system of claim 10, wherein said web site server is further configured to periodically purge said database of records exceeding a time threshold.

13. The system of claim 10, wherein to dynamically update said database said web site server is configured to dynamically update records existing therein.

14. A non-transitory computer-accessible storage medium, comprising program instructions that when executed by a hardware computer system to cause said hardware computer system to:

determine whether a user of a first computer accessing a website is a distinct user, wherein to determine whether the user of the first computer accessing the website is the distinct user, the program instructions, when executed, cause the hardware computer system to;

compare a first identifier, comprising a first Internet address and a first time value that corresponds to an event associated with said first computer, received from said first computer with one or more identifiers stored in a database;

identify the user as the distinct user corresponding to said first computer in response to no match being found for said first identifier among said one or more identifiers stored in said database, wherein to improve accuracy of web hit counting the user is identified as a distinct user even when said first Internet address matches a particular Internet address of one or more of the records in said database that indicate accessing of said website;

increment a hit counter by one in response to identifying the distinct user; and

add to said database a new record comprising said first Internet address and said first time value in response to identifying the distinct user.

15. The non-transitory computer-accessible storage medium of claim 14, wherein a match for said first identifier comprises a match between said first Internet address and an Internet address in one of said one or more identifiers stored in said database as well as a match between said first time value and a time value in said one of said one or more identifiers stored in said database.

16. The non-transitory computer-accessible storage medium of claim 14, wherein said one or more identifiers stored in said database were obtained from one or more computers having previously accessed the web site.

17. The non-transitory computer-accessible storage medium of claim 14, wherein said first computer comprises a personal computer, a laptop computer, a notebook computer, an Internet-enabled cellular phone, an Internet-enabled personal digital assistant, or a web television system.

18. The non-transitory computer-accessible storage medium of claim 14, wherein said program instructions when executed further causes said hardware computer system to identify an approximate geographic location of said first computer.
