Abstract

Cookie files are screened in a client machine, wherein a cookie file includes a cookie file source. A request from a subscriber is received at a server to send a list of untrusted cookie file sources to the client machine. The list of untrusted cookie file sources is downloaded from the server to the client machine. The downloaded list of untrusted cookie file sources is used to detect cookie files received at the client machine from cookie file sources on the downloaded list by comparing the cookie file source of any received cookie file to the untrusted cookie file sources on the downloaded list.

Claims

1. A method of screening cookie files in a client machine, wherein a cookie file includes a cookie file source, the method comprising:

(a) receiving, at a server, a request from a subscriber to send a list of untrusted cookie file sources to the client machine;

(b) downloading the list of untrusted cookie file sources from the server to the client machine; and

(c) using the downloaded list of untrusted cookie file sources to detect cookie files received at the client machine from cookie file sources on the downloaded list by comparing the cookie file source of any received cookie file to the untrusted cookie file sources on the downloaded list.

2. The method of claim 1 further comprising:

(d) creating at least one of a first exception list including the identity of cookie file sources that are permitted to store cookie files in the client machine, and a second exception list including the identity of cookie file sources that are not permitted to store cookie files in the client machine; and

(e) modifying the downloaded list in accordance with the at least one of a first and second exception lists.

3. The method of claim 1 further comprising:

(d) receiving updates of the downloaded list from the server on a periodic basis.

4. The method of claim 1 further comprising:

(d) displaying a message at the client machine indicating that a cookie file received from a cookie file source on the downloaded list has been detected.

5. The method of claim 1 further comprising:

(d) maintaining a watch list of untrusted cookie file sources at the server, wherein the downloaded list of untrusted cookie file sources is obtained from the watch list.

6. A method of creating a composite list of cookie file sources in a client machine, the method comprising:

(a) creating a first exception list including the identity of cookie file sources that are permitted to store cookie files in the client machine, wherein a cookie file includes a cookie file source;

(b) creating a second exception list including the identity of cookie file sources that are not permitted to store cookie files in the client machine;

(c) receiving at the client machine, from a service provider, a master list of untrusted cookie file sources; and

(d) modifying the master list in accordance with the first and second exception lists, wherein the composite list is the modified master list.

7. The method of claim 6 wherein the composite list is stored in the client machine independent of the first exception list, the second exception list and the received master list.

8. The method of claim 6 further comprising:

(e) receiving updates of the master list from the service provider on a periodic basis.

9. The method of claim 6 further comprising:

(e) maintaining a watch list of untrusted cookie file sources at the service provider, wherein the master list of untrusted cookie file sources that is received at the client machine from the service provider is obtained from the watch list.

10. The method of claim 6 further comprising:

(e) receiving, at the service provider, a request from the client machine to send a master list of untrusted cookie file sources to the client machine, wherein the master list of untrusted cookie file sources received at the client machine is received in response to the request from the client machine.

11. A method of creating a composite list of cookie file sources in a client machine, the method comprising:

(a) receiving at the client machine, from a service provider, a master list of untrusted cookie file sources;

(b) deleting cookie file sources from the master list that correspond to one or more trusted cookie file sources listed in the client machine; and

(c) adding cookie file sources to the master list that correspond to one or more untrusted cookie file sources listed in the client machine, wherein the composite list is the master list as modified by any additions and deletions of trusted and untrusted cookie file sources.

12. The method of claim 11 wherein the master list and the composite list are stored independently in the client machine.

13. The method of claim 11 further comprising:

(d) maintaining a watch list of untrusted cookie file sources at the service provider, wherein the master list of untrusted cookie file sources that is received at the client machine from the service provider is obtained from the watch list.

14. The method of claim 11 further comprising:

(d) receiving, at the service provider, a request from the client machine to send a master list of untrusted cookie file sources to the client machine, wherein the master list of untrusted cookie file sources received at the client machine is received in response to the request from the client machine.

15. An article of manufacture for screening cookie files in a client machine, wherein a cookie file includes a cookie file source, the article of manufacture comprising a computer-readable medium holding computer-executable instructions for performing a method comprising:

(a) receiving, at a server, a request from a subscriber to send a list of untrusted cookie file sources to the client machine;

(b) downloading the list of untrusted cookie file sources from the server to the client machine; and

(c) using the downloaded list of untrusted cookie file sources to detect cookie files received at the client machine from cookie file sources on the downloaded list by comparing the cookie file source of any received cookie file to the untrusted cookie file sources on the downloaded list.

16. The article of manufacture of claim 15 wherein the computer-executable instructions perform a method further comprising:

(d) creating at least one of a first exception list including the identity of cookie file sources that are permitted to store cookie files in the client machine and a second exception list including the identity of cookie file sources that are not permitted to store cookie files in the client machine; and

(e) modifying the downloaded list in accordance with the at least one of a first and second exception lists.

17. The article of manufacture of claim 15 wherein the computer-executable instructions perform a method further comprising:

(d) receiving updates of the downloaded list from the server on a periodic basis.

18. The article of manufacture of claim 15 wherein the computer-executable instructions perform a method further comprising:

(d) displaying a message at the client machine indicating that a cookie file received from a cookie file source on the downloaded list has been detected.

19. The article of manufacture of claim 15 wherein the computer executable instructions perform a method further comprising:

(d) maintaining a watch list of untrusted cookie file sources at the server, wherein the downloaded list of untrusted cookie file sources is obtained from the watch list.
