Abstract:
The present invention relates to image management systems and methods. In one implementation we provide a method to provide geo-location feedback corresponding to an image area selected by a user. A digital watermark embedded in the selected image area is decoded, and the decoded digital watermark includes or points to geo-location information associated with the selected image location. In another implementation we provide an alert engine to notify a network station that information associated with a digital watermark identifier is available.
