Abstract
Methods and systems include: (1) steganographically embedding location information in images, where the location information is obtained from remote sources like a cell phone network or remote GPS receiver; (2) steganographically embedding participant IDs in content to ensure proper billing and royalty tracking; (3) providing a fingerprint database which is limited to a play list for a particular broadcast network over a predetermined period; (4) providing fair-use content management based upon digital watermark-tracked usage; (5) providing micro-payments based upon watermarked ID cards for retailers; or (6) providing watermarked logon cards, such as watermarked hotel room keys, to better provide internet logon access control.

13. A method of providing internet access for a computer user comprising:
-
issuing the user a digitally watermarked object, wherein the digitally watermarked object comprises a digital watermark embedded therein, the digital watermark comprising an identifier;
associating the identifier with the user via a data repository;
receiving optical scan data corresponding to a portion of the object, the portion comprising the digital watermark;
decoding the digital watermark from the scan data to obtain the identifier;
verifying that the identifier is valid; and
enabling internet access for the user when the identifier is valid. - View Dependent Claims (14, 15)

16. A method of accumulating financial charges attributable to a customer so as to minimize transaction fees, the customer possession a digitally watermarked object, the digitally watermarked object comprising a digital watermark including an identifier, said method comprising:
-
receiving scan data associated with the digitally watermarked object;
analyzing the scan data to obtain the identifier from the object;
accessing a data record that is associated with the identifier;
updating the data record to reflect a monetary amount owed for a transaction;
accumulating a plurality of such monetary amounts in the data record; and
forwarding the accumulated amounts for payment at least when one of the following occur;
a predetermined amount for the accumulated amount is reached, and after a predetermined amount of time. - View Dependent Claims (17, 18, 19, 20, 21, 22, 23)

24. A method to regulate protected content while allowing fair use of the content, wherein the content includes a digital watermark embedded therein, the digital watermark including at least a copy protection indicator and a time interval indicator, said method comprising:
-
recognizing the content as protected content by reference to the copy protection indicator; and
upon recognition of the content as protected content, measuring the amount of content rendered by reference to the time interval indicator, and disabling rendering after a predetermined amount of content has been rendered, the predetermined amount corresponding to fair use of the content.

25. A method for providing royalty payments for content distributed via a network, said method comprising:
-
receiving registration information from a participant who requires royalty payments for content to be distributed;
assigning a unique identifier to the participant;
steganographically embedding the content with the identifier; and
associating a royalty payment action with the identifier in a data repository. - View Dependent Claims (26, 27, 28)

30. A method of monitoring a content item which is to be broadcast through a broadcasting network, the content item to be identified by a fingerprint of the content derived from the content itself, said method comprising:
-
maintaining a limited list of content items, the list consisting of those content items that are to be broadcast by the broadcasting network during a predetermined time period, the limited list of content items being respectively associated with one or more fingerprints derived from the content items themselves;
deriving a fingerprint from a content item monitored from the broadcast network; and
interrogating the limited list of content items with the fingerprint to identify the monitored content item.
