1. A method of document classification, said method comprising:
- receiving, at a classification station, a physical document comprising one or more pages;
applying, at the classification station, a classification code to the physical document, wherein the classification code is formed using an ink that is (1) not visible to the unaided eye when viewed under natural light and (2) visible when illuminated by wavelengths outside the visible spectrum, wherein the classification code is applied to the physical document prior to scanning;
scanning, with aid of an image capture device, the physical document into one or more images of the one or more pages of the physical document in a digital format, wherein the classification code is not visible in the one or more images of the one or more pages of the physical document;
scanning the classification code under illumination of wavelengths outside the visible spectrum;
associating the classification code to the digital format of the physical document without having the classification code visible in the one or more images; and
storing both (i) the digital format of the physical document digitally associated with the classification code, wherein the classification code is not visible in the one or more images of the physical document, and (ii) the physical document physically associated with the classification code, wherein the classification code is not visible under natural light but capable of being identified under illumination of the wavelengths outside the visible spectrum for future processing of the physical document.

Abstract
Systems and methods are provided for document classification and digitization. One or more physical documents may have a classification code applied thereon. The classification code may be a unique identifier for the document and/or page of the document. The classification code may utilize ink outside the visible spectrum for the purpose of being machine readable. A digital version of the physical document may be created. The digital version may include a visible reproduction of the document without showing the classification code.

7. An assembly for document digitization and classification, said assembly comprising:
-
a classification station configured to (1) receive a physical document comprising one or more pages, and (2) apply a classification code to the physical document, wherein the classification code is formed using an ink that is (i) not visible to the unaided eye when viewed under natural light and (ii) visible when illuminated by wavelengths outside the visible spectrum, wherein the classification code is applied to the physical document prior to scanning; a scanning station comprising an image capture device configured to (1) scan the classification code under illumination of wavelengths outside the visible spectrum and (2) scan the physical document into one or more images of the one or more pages of the physical document in a digital format, wherein the classification code is not visible in the one or more images of the one or more pages of the physical document; and a processor configured to associate the classification code to the digital format of the physical document without having the classification code visible in the one or more images, thereby storing both (i) the digital format of the physical document digitally associated with the classification code, wherein the classification code is not visible in the one or more images of the physical document, and (ii) the physical document physically associated with the classification code, wherein the classification code is not visible under natural light but capable of being identified under illumination of the wavelengths outside the visible spectrum for future processing of the physical document. - View Dependent Claims (8, 9, 10, 11, 12)

13. A method of document classification, said method comprising:
-
receiving, at a classification station, a physical document comprising one or more pages; applying, at the classification station, a classification code to the physical document, wherein the classification code is formed using an ink that is (1) not visible to the unaided eye when viewed with natural light illumination and (2) visible when illuminated by wavelengths outside the visible spectrum, wherein the classification code is applied to the physical document prior to scanning, and wherein the classification code includes timing information relating to an event associated with the physical document; scanning, with aid of an image capture device, the physical document into one or more images of the one or more pages of the physical document in a digital format; scanning the classification code under illumination of wavelengths outside the visible spectrum; associating the classification code to the digital format of the physical document; and storing both (i) the digital format of the physical document digitally associated with the classification code, and (ii) the physical document physically associated with the classification code. - View Dependent Claims (14, 15, 16, 17, 18)
