Abstract

The present invention relates to methods of, and systems for, tracking content in communication networks by collecting content transmission information from the network. The collected content transmission is examined to identify discrete content items, and these are compared to predetermined content items. The result of the comparison is stored on a database, and if an identified discrete content item is the same as or substantially similar to a predetermined content item and/or if an identified discrete content item has been previously sent to or received by a subscriber or application, an event signal is triggered.

Claims

1. A method of tracking content in messages distributed between subscribers on a communications network, the method including:

—

collecting message content transmission information sent or received by a subscriber;

examining the collected content transmission information to identify discrete content items;

comparing identified discrete content items with predetermined content items;

determining if an identified discrete content item is the same as or substantially similar to a predetermined content item and/or determining if an identified discrete content item has been previously sent to or received by a subscriber or application;

storing the result of the comparison and/or determination, and

generating an event triggering signal if it is determined that an identified discrete content item is the same as or substantially similar to a predetermined content item, and/or if it is determined that an identified discrete content item has been previously sent to or received by a subscriber.

2. A method of tracking content as claimed in claim 1, wherein the message content transmission information is collected by examining messages stored in a network message server.

3. A method of tracking content as claimed in claim 1, wherein the message content transmission information is collected by passively examining messages during transmission by using an Internet Protocol packet capture device.

4. A method of tracking content as claimed in claim 1, wherein the message content transmission information is collected by passively examining Internet Protocol traffic.

5. A method of tracking content as claimed in claim 1, wherein the message content transmission information is collected by monitoring a network element serving as a proxy to which messages are first sent before being transmitted.

6. A method of tracking content as claimed in claim 1, wherein the collected message content transmission information is examined by decompiling the message.

7. A method of tracking content as claimed in claim 1, wherein the discrete content items include at least one of image, text, audio including music, video, application.

8. A method of tracking content as claimed in claim 7, wherein text content is compared by using regular expression comparison techniques.

9. A method of tracking content as claimed in claim 7, wherein image, video or sound content is compared by comparing checksums of the digitized content.

10. A method of tracking content as claimed in claim 7, wherein image, video or sound content is compared by comparing a characteristic signature of the content.

11. A method of tracking content as claimed in claim 7, wherein image, video or sound content is compared by qualitative comparison methods comparing significant features of the content.

12. A method of tracking content as claimed in claim 7, wherein image, video or sound content is compared by utilising Content Based Image Retrieval (CBIR) comparison methods.

13. A method of tracking content as claimed in claim 1, wherein the comparison process is optimised for rapid comparison of content.

14. A method of tracking content as claimed in claim 1, wherein the comparison process compares a characteristic signature of the content rather than the content itself.

15. A method of tracking content as claimed in claim 1, wherein the result is stored as statistical information about the content.

16. A method of tracking content as claimed in claim 1, wherein the signal triggers a billing event in a billing system.

26. A system including logic stored on a computer readable medium for performing the method according to any one of claims 1, 17 and 18.

17. A method of tracking content in messages distributed between subscribers on a communications network, the method including:

—

collecting message content information from the network;

examining the collected message content information to identify discrete content items;

comparing a characteristic signature of identified discrete content items with a characteristic signature of predetermined content items;

determining if a characteristic signature of an identified discrete content item is the same as or substantially similar to a characteristic signature of a predetermined content item and/or determining if an identified discrete content item has been previously sent to or received by a subscriber;

storing the result of the comparison and/or determination, and

generating an event triggering signal if it is determined that a characteristic signature of an identified discrete content item is the same as or substantially similar to a characteristic signature of a predetermined content item, and/or if it is determined that an identified discrete content item has been previously sent to or received by a subscriber.

18. A method of tracking content transmitted on a communications network, the method including:

—

collecting content transmission information sent or received by a subscriber or application;

reassembling the collected content transmission information to identify discrete content items; and

determining and storing a characteristic signature for each content item with an associated content item transmission information in a database.

19. A method of tracking content as claimed in claim 18, wherein the characteristic signature and transmission information for each content item is compared with a previously stored content item signature and transmission information to determine if the same or substantially similar content item has been previously sent to or received by a subscriber or application;

and

storing the result of the comparison.

20. A method of tracking content as claimed in claim 19, wherein the result of the comparison is used to determine and/or report on the transmission of identical or related content items between subscribers, and between subscribers and applications.

21. A method of tracking content as claimed in claim 19 wherein the result of the comparison is recursively searched to determine the transmission path of identical or related content, as opposed to discrete content transmission events.

22. A method of tracking content as claimed in claim 19 wherein the result of the comparison is used to count the number of times a content item has been transmitted on the network.

23. A method of tracking content as claimed in claim 18, wherein a hierarchy of content item signatures are stored to record a relationship between content items that are part of the same transmission but have been modified.

24. A method of tracking content as claimed in claim 23 wherein related content items are determined by collecting network packets at multiple points in the network, including before and after the network element, that may adapt the content.

25. A method of tracking content as claimed in claim 19 wherein according to predetermined business rules, a copy of the original content is stored with the associated characteristic signature.
