Embedding 3D information in documents
Methods, systems, and apparatus, including computer programs encoded on a computer storage medium, for obtaining information to be embedded within an identification document. Modifying the information to add depth when viewed through a three-dimensional (3D) viewing device, thereby yielding modified information. Embedding the modified information in a target image to yield a modified target image such that the modified information is not viewable to a naked eye and the modified information is visible with added depth when viewed through a 3D viewing device. Disposing the modified target image on an identification document to yield embedded 3D information. An identification document includes the target image and 3D information embedded within the target image. The 3D information embedded within the target image is not visible to a naked eye, but is visible with added depth when viewed through a 3D viewing device.
1. A method of making an identification document with embedded 3D information, the method comprising:
obtaining, by one or more processors, information to be embedded within an identification document;
modifying, by the one or more processors, the information to add depth when viewed through a 3D viewing device, thereby yielding modified information;
embedding, by the one or more processors, the modified information in a target image to yield a modified target image such that the modified information is not perceivable without the 3D viewing device and the modified information is visible with added depth when viewed through the 3D viewing device, wherein embedding the modified information in the target image comprises modifying pixels of the target image with pixels of the modified information; and
causing, by the one or more processors, the modified target image to be disposed on an identification document to yield embedded 3D information.
2. The method of claim 1 , wherein modifying the information comprises:
generating a left eye image of the information and a right eye image of the information; and
combining the left eye image and the right eye image to yield the modified information.
3. The method of claim 1 , wherein the information comprises text, a graphic, or an image.
4. The method of claim 1 , wherein modifying the pixels of the target image with the pixels of the modified information comprises:
mapping pixels of the modified information to respective pixels of the target image so as to position the modified information at a desired location within the target image; and
performing a mathematical or a logical operation between mapped pixels of the modified information and corresponding pixels of the target image.
5. The method of claim 1 , wherein modifying the pixels of the target image with the pixels of the modified information comprises replacing the pixels of the target image with the pixels of the modified information.
6. The method of claim 2 , wherein the left eye image comprises a first color and the right eye image comprises a second color that is chromatically opposite to the first color.
7. The method of claim 1 , wherein causing the modified target image to be disposed on the identification document comprises printing the modified target image on a layer of the identification document.
8. The method of claim 1 , wherein causing the modified target image to be disposed on the identification document comprises encoding the modified target image in a digital identification document.
9. The method of claim 1 , wherein the identification document is a digital identification document, and
wherein modifying the information comprises generating a left eye image of the information and a right eye image of the information; and
wherein embedding the modified information in the target image comprises:
combining the left eye image with the target image to yield a left eye target image; and
combining the right eye image with the target image to yield a right eye target image, and
wherein disposing the modified target image on an identification document comprises encoding instructions within the identification document that cause a computing device to alternately display the left eye target image and the right eye target image such that the information is viewable with added depth when viewed through an electronic 3D viewing device.
10. The method of claim 9 , wherein the target image is a digital image of the identification document.
11. The method of claim 4 , wherein the mathematical operation comprises one or more of addition, subtraction, multiplication, or division between pixels.
12. The method of claim 4 , wherein the logical operation comprises one or more of a logical AND operation, a logical OR operation, or a logical exclusive OR (XOR) operation between pixels.
13. A non-transitory computer readable storage medium storing instructions that, when executed by at least one processor, cause the at least one processor to perform operations comprising:
obtaining information to be embedded within an identification document;
modifying the information to add depth when viewed through a 3D viewing device, thereby yielding modified information;
embedding, by the one or more processors, the modified information in a target image to yield a modified target image such that the modified information is not perceivable without the 3D viewing device and the modified information is visible with added depth when viewed through the 3D viewing device, wherein embedding the modified information in the target image comprises modifying pixels of the target image with pixels of the modified information; and
causing the modified target image to be disposed on an identification document to yield embedded 3D information.
14. A system comprising:
one or more computers; and one or more data stores coupled to the one or more computers, the one or more data stores having instructions to embed 3D information in a document stored thereon which, when executed by the one or more computers, causes the one or more computers to perform operations comprising:
obtaining information to be embedded within an identification document;
modifying the information to add depth when viewed through a 3D viewing device, thereby yielding modified information;
embedding, by the one or more processors, the modified information in a target image to yield a modified target image such that the modified information is not perceivable without the 3D viewing device and the modified information is visible with added depth when viewed through the 3D viewing device, wherein embedding the modified information in the target image comprises modifying pixels of the target image with pixels of the modified information; and
causing the modified target image to be disposed on an identification document to yield embedded 3D information.
15. The system of claim 14 , wherein modifying the information comprises:
generating a left eye image of the information and a right eye image of the information; and
combining the left eye image and the right eye image to yield the modified information.
16. The system of claim 14 , wherein the information comprises text, a graphic, or an image.
17. The system of claim 14 , wherein modifying the pixels of the target image with the pixels of the modified information comprises:
mapping pixels of the modified information to respective pixels of the target image so as to position the modified information at a desired location within the target image; and
performing a mathematical or a logical operation between mapped pixels of the modified information and corresponding pixels of the target image.
18. The system of claim 14 , wherein modifying the pixels of the target image with the pixels of the modified information comprises replacing the pixels of the target image with the pixels of the modified information.
19. The system of claim 15 , wherein the left eye image comprises a first color and the right eye image comprises a second color that is chromatically opposite to the first color.
