First Claim
Patent Images
1. A method performed at a content recipient on a network, the method comprising the following steps:
- a) receiving an image from a Web site over the network;
b) computing, at the content recipient, a checksum from the received image, the content recipient not being the original network source of the received image;
c) transmitting the checksum from the content recipient to a data collection site over the network; and
, d) transmitting the image from the content recipient to the data collection site over the network in response to a message from the data collection site indicating that the content recipient should transmit the image.

Abstract
A checksum is extracted from an image downloaded to a content recipient. The content recipient transmits the extracted checksum to a data collection site. The data collection site compares the received checksum to a reference checksum. If the received checksum and the reference checksum match, the data collection site uses an image corresponding to the reference checksum as the downloaded image. If the received checksum and the reference checksum do not match, the data collection site retrieves the down-loaded image from the content recipient.

15. A method performed at a data collection site on a network, the method comprising the following steps:
-
a) receiving a checksum from a content recipient over the network, wherein the checksum is related to an image transmitted to the content recipient over the network, and wherein the checksum is computed at the content recipient, and wherein the content recipient is not the original network source of the transmitted image;
b) comparing a reference checksum to the received checksum;
c) if the received and reference checksums do not match, transmitting to the content recipient over the network a message from the data collection site indicating that the content recipient should transmit the image; and
,d) receiving the image from the content recipient over the network in response to step c). - View Dependent Claims (16, 17, 18, 19, 20, 21, 22, 23, 24, 25, 26, 27, 28, 29, 30)
retrieving a reference image from a Web site; and
,computing the reference checksum from the reference image.

17. The method of claim 15 wherein step c) comprises the following steps:
-
c1) if the received and reference checksums do not match, retrieving the image from a source other than the content recipient;
c2) if the image cannot be successfully retrieved from the source, transmitting to the content recipient the message from the data collection site indicating that the content recipient should transmit the image.

-
18. The method of claim 15 wherein step a) comprises the step of receiving non-checksum information related to the image.
-
19. The method of claim 18 wherein the non-checksum information includes a size of the image.
-
20. The method of claim 18 wherein the non-checksum information includes a location of the image on a page.
-
21. The method of claim 18 wherein the non-checksum information includes a URL of a page containing the image.
-
22. The method of claim 18 wherein the non-checksum information includes a URL of the image.
-
23. The method of claim 18 wherein the non-checksum information includes a URL of a click-through location.
-
24. The method of claim 18 wherein the non-checksum information includes an identification tag which identifies the image.
-
25. The method of claim 18 wherein the non-checksum information includes ALT text relating to the image.
-
26. The method of claim 18 wherein the non-checksum information includes duration of image exposure.
-
27. The method of claim 15 wherein step b) comprises the step of accessing the image from memory at the data collection site if the received and reference checksums match.
-
28. The method of claim 27 wherein the step of accessing the image from memory comprises the step of accessing the image from memory based upon the received checksum.
-
29. The method of claim 15 wherein step b) comprises the step of retrieving the reference checksum from memory.
-
30. The method of claim 29 wherein step c) comprises the step of retrieving the image from memory if the reference checksum and the received checksum match.
-
31. A method performed at a data collection site on a network, the method comprising:
-
a) receiving a first image identifier from a content recipient over the network, wherein the first image identifier is related to a first image transmitted to the content recipient, and wherein the content recipient is not the original network source of the first image, and wherein the first image identifier includes a checksum related to the first image;
b) receiving a second image over the network from a source other than the content recipient based upon the first image identifier;
c) determining a second image identifier corresponding to the second image, wherein the second image identifier includes a checksum related to the second image;
d) saving the second image in connection with the content recipient if the first and second image identifiers match;
e) if the first and second image identifiers do not match, transmitting to the content recipient over the network a message from the data collection site indicating that the content recipient should transmit the first image; and
,f) receiving the first image from the content recipient over the network in response to the message. - View Dependent Claims (32, 33, 34, 35, 36)
