Oh, Patents! Digimarc® barcodes (3)

Copyright © Françoise Herrmann


Digimarc® barcodes offer an AR (Augmented Reality) shopping experience. As a reminder, in AR the user brings together the real world and the virtual world in real-time interaction, which ultimately imposes new properties on physical objects (private and/or public), and thus deepens (augmenting and/or amplifying) the real world experience. So, for example, when reading the Digimarc® barcode of supermarket products, the user is able to bring to the shelf products vast amounts of data stored in databases about the product, and how to use it. The Digimarc® barcode is a bit like QR Codes, which multiply the amount of coded information about a product, including the possibility of connecting you to the Internet, only the Digimarc® barcode is also invisible, or at least hardly perceptible to the naked eye.


The invisibility of this invention invokes the 700-year-old steganographic (occultist) idea of hiding text within texts, which Digimarc® inventors now call the payload of hidden data concealed in an image. Recited in almost 2000 patents, Digimarc® processes map the invisible with a host of mathematical transform theories, applied to computer science.

The two latest Digimarc® patent applications US20180047126 and US20180047127, both titled Signal encoding for difficult environments and published on Feb. 15, 2018, disclose the selection of inks for the design of a package, and how to encode them with payload information, so that this information may be remotely decoded using principles based on spectral reflectance.

The abstract for US 20180047127 is included below :

This disclosure relates to advanced image signal processing technology including encoded signals and digital watermarking. We disclose methods, systems and apparatus for selecting which ink(s) should be selected to carry an encoded signal for a given machine-vision wavelength for a retail package or other printed design. We also disclose retail product packages and other printed objects, and methods to generate such, including a sparse mark in a first ink and an overprinted ink flood in a second ink. The first ink and the second ink are related through tack and spectral reflectance difference. Of course, other methods, packages, objects, systems and apparatus are described in this disclosure.
