Abstract

Among other things, at a cloud-based service, digital image files are received from which digital images can be displayed on devices. For each of the digital image files, data is embedded in the digital image file on behalf of a party who has rights in the digital image file. The existence of the embedded data is not perceptible in any digital image that is displayed using the digital image file. The embedded data includes information from which the digital image file can be authenticated. At the cloud-based service, a digital image file is received that is to be authenticated. The digital image file is authenticated based on the embedded data.

receiving at the cloud-based service, a digital image file to be authenticated, and

authenticating the digital image file in a process running on a computer and that uses the embedded data.

2. The method of claim 1 in which the embedded data comprises a hash of data in the digital image file.

3. The method of claim 1 in which the embedded data can be used to locate information about the digital image file that has been stored at the cloud-based system.

4. The method of claim 1 comprising

storing at the cloud-based system information about the digital image file that can be retrieved based on the embedded data.

5. The method of claim 1 in which each of the digital image files is received through a publicly accessible communication network.

6. The method of claim 1 in which the embedded data includes a key or identifier to information about the instance of the digital image file that is stored at the cloud-based service, separately from the digital image file.

7. The method of claim 6 in which the information about the instance of the digital image file includes at least one of:

an identification of a party who has rights in the instance of the digital image file, an identification of the edition to which the instance belongs, and an identification of the instance of the digital image file that is included in the limited edition.

8. The method of claim 1 comprising, after the digital image file has been authenticated, providing information to a user.

9. The method of claim 8 in which the information provided to the user is determined by characteristics of the user.

10. The method of claim 8 in which the information provided to the user includes the result of the authenticating.

11. The method of claim 8 in which the information provided to the user includes an identification of a party who has rights in the digital image file.

12. The method of claim 1 comprising, after the data has been embedded in the digital image file, providing information to a user.

13. The method of claim 12 in which the information provided to the user includes image data associated with the unique identifier of the instance of the digital image file.

14. The method of claim 12 in which the information provided to the user includes confirmation that the data has been embedded.

15. The method of claim 1 comprising storing the digital image files at the cloud-based service.

16. The method of claim 1 in which the digital image files are received from a web browser or a mobile app of a user device.

17. The method of claim 1 comprising receiving information that defines a limited edition of instances of the digital image file.

18. The method of claim 1 comprising providing an image storage system for distribution of instances of the digital image files subject to conditions specified on behalf of a party who has rights in the digital image file and agreed to by a user.

19. The method of claim 18 comprising delivering an instance of the digital image file to the user who has agreed to the conditions.

20. The method of claim 19 in which the user can display a digital image based on the instance of the digital image file.

21. The method of claim 1 in which the embedded data comprises a digital watermark.

22. A method comprising

from a cloud-based service, delivering to a user device an instance of a digital image file in which data has been embedded at the cloud-based service on behalf of a party who has rights in the digital image file, the embedding of data including associating by a process running on a computer, a unique identifier or key with a single instance of a limited edition of the digital image file, and

controlling the delivery of the instance of the digital image file containing the embedded data to the user in compliance with conditions that have been specified on behalf of the party who has rights in the digital image file, a digital image being displayable on a user device based on the instance of the digital image file.

23. The method of claim 22 in which the instance of the digital image file is delivered through a web browser or a mobile app.

24. The method of claim 22 in which the user device comprises a device that includes a screen and a processor that can display the digital image using the instance of the digital image file.

25. The method of claim 22 in which the instance of the digital image file comprises one instance among one or more instances of a limited edition of the digital image file.

26. The method of claim 22 in which the user device on which the display is occurs comprises a mobile phone, TV monitor, projector, or any other screen or display device.

27. A method comprising

at a user device, receiving an instance of a digital image file from a cloud-based service, the digital image file having had data embedded in it by a process running on a computer at the cloud-based service to protect rights of a user in the digital image file, the digital image file comprising a limited edition that includes one or more instances of the digital image file, the embedding having been done on behalf of a party who has rights in the digital image file, the existence of the embedded data not being perceptible in any digital image that is displayed using the digital image file, the embedded data including information that can be used in a process of authenticating the digital image, the embedded data being uniquely associated with the limited edition,

the digital image file being received only on the basis of an agreement by a user to conditions for use of the digital image file, and

displaying a digital image using the watermarked instance of the digital image file.

28. The method of claim 27 in which the digital image is displayed on a user device.

29. The method of claim 28 in which the user device on which the digital image is displayed is the user device that received the instance of the digital image file.

30. The method of claim 28 in which the user device on which the digital image is displayed is a device that is accessible to the user device that received the instance of the digital image file.
