Abstract

A watermark is generated. The generated watermark is specific to an individual owner of a media. The media may be any type of electronic media, such as, an image, a document, a movie, an audio file, a software application, and/or the like. The watermark is inserted into the media. The watermark in the media is changed when ownership of the media is changed. For example, as the media is sold to a new owner, the new owner's watermark is added to the media so that a chain of title can be verified directly from the media. In addition, the chain of title may also be verified via a blockchain.

Claims (35)

1 . A system comprising:

a microprocessor; and

a computer readable medium, coupled with the microprocessor and comprising microprocessor readable and executable instructions that, when executed by the microprocessor, cause the microprocessor to:

generate a watermark, wherein the watermark is specific to an individual owner; and

insert the watermark into a media, wherein the watermark in the media is changed when ownership of the media is changed; and

wherein the watermark in the media comprises a plurality of watermarks that comprise a chain-of-title for the media, wherein each of the plurality of watermarks identifies one of a creator, a previous owner, or a current owner, and wherein each of the plurality of watermarks are stored in different locations in the media; and

wherein the plurality of watermarks further comprises one or more links to link the plurality of watermarks together to form the chain-of-title in the media.

2 . The system of claim 1 , wherein each of the plurality of watermarks are stored in separate blocks in a chain-of-title blockchain.

3 . The system of claim 2 , wherein each of the separate blocks in the chain-of-title blockchain further comprise a hash of the media and/or watermark when the media was created or sold to the current owner.

4 . The system of claim 3 , wherein the chain-of-title blockchain tracks a maximum number of copies.

5 . The system of claim 3 , wherein a transaction block in the chain chain-of-title blockchain identifies a number of times a copy of the media can be sold/transferred.

6 . The system of claim 2 , wherein the chain-of-title blockchain comprises a plurality of branches that individually track individual copies of the media and ownership of the individual copies of the media.

7 . The system of claim 6 , wherein the plurality of branches track individual media rights for each of the individual copies of the media.

8 . The system of claim 1 , wherein the plurality of watermarks are stored in fixed locations within the media.

9 . The system of claim 1 , wherein the watermark is a partial chain of title watermark.

10 . A method comprising:

generating, by a microprocessor, a watermark, wherein the watermark is specific to an individual owner; and

inserting, by the microprocessor, the watermark into a media, wherein the watermark in the media is changed when ownership of the media is changed; and

wherein the watermark in the media comprises a plurality of watermarks that comprise a chain-of-title for the media, wherein each of the plurality of watermarks identifies one of a creator, a previous owner, or a current owner, and wherein each of the plurality of watermarks are stored in different locations in the media;

wherein each of the plurality of watermarks are stored in separate blocks in a chain-of-title blockchain; and

wherein the chain-of-title blockchain comprises a plurality of branches that individually track individual copies of the media and ownership of the individual copies of the media.

11 . The method of claim 10 , wherein a transaction block in the chain-of-title blockchain identifies a number of times a copy of the media can be sold/transferred.

12 . The method of claim 10 , wherein the plurality of watermarks further comprises one or more links to link the plurality of watermarks together to form the chain-of-title in the media.

13 . The method of claim 10 , wherein the plurality of watermarks are stored in fixed locations within the media.

14 . The method of claim 10 , wherein the watermark is a partial chain of title watermark.

15 . A non-transitory computer readable medium having stored thereon instructions that cause a microprocessor to execute a method, the method comprising instructions to:

generate a watermark, wherein the watermark is specific to an individual owner; and

insert the watermark into a media, wherein the watermark in the media is changed when ownership of the media is changed; and

wherein the watermark in the media comprises a plurality of watermarks that comprise a chain-of-title for the media, wherein each of the plurality of watermarks identifies one of a creator, a previous owner, or a current owner, and wherein each of the plurality of watermarks are stored in different locations in the media; and

wherein the plurality of watermarks further comprises one or more links to link the plurality of watermarks together to form the chain-of-title in the media.

16 . The non-transitory computer readable medium of claim 15 , wherein each of the plurality of watermarks are stored in separate blocks in a chain-of-title blockchain.

17 . The non-transitory computer readable medium of claim 16 , wherein each of the separate blocks in the chain-of-title blockchain further comprise a hash of the media and/or watermark when the media was created or sold to the current owner.

18 . The non-transitory computer readable medium of claim 16 , wherein the chain-of-title blockchain comprises a plurality of branches that individually track individual copies of the media and ownership of the individual copies of the media.

19 . The non-transitory computer readable medium of claim 18 , wherein the plurality of branches track individual media rights for each of the individual copies of the media.

20 . The non-transitory computer readable medium of claim 18 , wherein the chain-of-title blockchain tracks a maximum number of copies.
