Digital watermarking methods, programs and apparatus
First Claim
1. A method of doing business, the business related to selling or distributing media, said method comprising the steps of:
- displaying media packaging or media information for examination by potential media purchasers, wherein the media packaging or information does not include the actual related media; and
presenting to a media purchaser a digitally watermarked object, wherein the object does not include the actual related media, but does include at least a digital watermark identifier which once decoded is used to link via the internet or a network to a server including storage, the storage including a digital version of the related media stored therein for download.

Abstract
The present invention provides various authentication and digital watermarking methods and apparatus. In one implementation, we use our techniques to authenticate clothing, e.g., flight jackets and designer clothing. The clothing includes machine-readable indicia, which is generally imperceptible to a human observer of the clothing. The method includes the steps of: i) providing the clothing to an optical sensor, which produces image data corresponding to the clothing; ii) analyzing the image data to detect the machine-readable indicia; and determining based at least in part on the machine-readable indicia whether the clothing is authentic.

- 17. A method of applying a digital watermark to a film product, the film product receiving light from an optical path of a camera, said method being characterized by providing light to an optical path of the camera, and providing a filter in the optical path of the camera, wherein the filter alters the luminance of light passing through the filter so as to embed a hidden digital watermark in an image formed on the film.

23. A method of applying a digital watermark to an image optically captured via a camera, the camera comprising an image sensor receiving light from an optical path, said method being characterized by providing light to the optical path of the camera;
- and providing a filter in the optical path of the camera, wherein the filter alters the luminance of light passing through the filter so as to embed a hidden digital watermark in an image representation as presented to the image sensors.
