Abstract

A method of controlling the reproduction of copyrighted images, includes the steps of: a) providing an image medium having a predetermined pattern of micro-dots; b) steganographically embedding a reproduction authorization signal within some copyrighted digital images and not in others; c) printing the copyrighted digital images on the image medium to produce copyrighted images; d) in an image reproduction apparatus, attempting to detect the predetermined pattern of micro-dots and the authorization signal in an image to be reproduced; e) if the authorization signal is detected, or the pattern of microdots is not detected, permitting reproduction of the image to be reproduced; and f) if the authorization signal is not detected and the pattern of microdots is detected, preventing the reproduction of the image to be reproduced.

Claims

1. A method of controlling the reproduction of copyrighted images, comprising the steps of:

a) providing an image medium having a predetermined pattern of micro-dots;

b) steganographically embedding a reproduction authorization signal, that is separate and distinct from the micro-dots, within some copyrighted digital images and not in others;

c) printing the copyrighted digital images on the image medium to produce copyrighted images;

d) in an image reproduction apparatus, attempting to detect the predetermined pattern of micro-dots and the authorization signal in an image to be reproduced;

e) if the authorization signal is detected, and the pattern of microdots is detected, overriding the micro-dot detection and permitting reproduction of the image to be reproduced; and

f) if the authorization signal is not detected and the pattern of microdots is detected, preventing the reproduction of the image to be reproduced.

2. The method claimed in claim 1, wherein the image reproduction apparatus scans the image to produce a reproduced digital image and attempts to detect the pattern of microdots and the embedded authorization signal from the reproduced digital image.

3. The method claimed in claim 1, wherein the reproduction apparatus is located in a kiosk.

4. The method claimed in claim 3, wherein the kiosk is a photographic reproduction kiosk.

5. The method claimed in claim 1, further comprising the step of steganographically embedding other information such as an identification of the image, a customer identification, identification of a copyright owner, or an identification of the generation of a reproduced copy of the image.

6. The method claimed in claim 1, wherein the steganographic information is reproduced and embedded within the reproduced image.

7. The method claimed in claim 1, wherein the steganographic information is modified and embedded within the reproduced image.

8. The method according to claim 1 wherein the micro-dots are yellow.

9. The method claimed in claim 1, further comprising the step of compensating a copyright holder when the image is reproduced.

10. The method claimed in claim 7, wherein the embedded information modified is the copy generation of the reproduced image, is incremented and is modified and embedded within the reproduced image.

11. The method claimed in claim 10, wherein the copy authorization further depends on the copy generation of the image to be reproduced.

12. The method claimed in claim 9, wherein the amount of compensation depends on the type of reproduction.

13. The method claimed in claim 1, wherein the copyrighted image is a reflection print image, a transparency image or a digital image and the reproduction is a reflection print image, a transparency image or a digital image.

14. The method claimed in claim 1, wherein the attempt to detect the micro-dots is performed prior to the attempt to detect the embedded authorization signal, and the copy is immediately authorized if the micro-dots are not detected.

15. The method claimed in claim 1, wherein the attempt to detect the authorization signal is performed prior to the attempt to detect the micro-dots, and the copy is immediately authorized if the authorization signal is detected.

16. The method claimed in claim 1, wherein the other information includes instructions to change the embedded information in a copy.

17. The method claimed in claim 1, further comprising the steps of:

a) steganographically embedding the identification of a copyright holder in the image;

b) retrieving the identification; and

c) compensating the copyright holder based upon the retrieved identification.

18. The method claimed in claim 17, wherein the reproduction apparatus automatically implements compensation to the copyright holder.

19. A method of creating a copyrighted image, comprising the steps of:

a) providing an image medium having a predetermined pattern of micro-dots;

b) steganographically embedding a reproduction authorization signal, that is separate and distinct from the micro-dots and that can override the micro-dot detection, within a copyrighted digital image; and

c) printing the copyrighted digital images on the image medium to produce copyrighted images.

20. An image created by the method of claim 19.

21. A method of controlling the reproduction of an image bearing document in a document reproduction apparatus, the document possibly being printed on a medium having a predetermined pattern of micro-dots, and possibly including a steganographically embedded reproduction authorization signal separate and distinct from the micro-dots, the method comprising the steps of:

a) attempting to detect the predetermined pattern of micro-dots and the authorization signal in the document;

b) if the authorization signal is detected, and the pattern of microdots is detected, overriding the micro-dot detection and permitting reproduction of the document; and

c) if the authorization signal is not detected and the pattern of microdots is detected, preventing the reproduction of the document.
