Authenticable digital code and associated systems and methods
First Claim
1. An authenticable digital code, comprising:
- a printable medium;
a machine-readable digital code, formed on the printable medium, that graphically represents information; and
at least one security signature comprising a fluorescent material that, when excited by first light at a first wavelength, fluoresces and emits second light at a second wavelength, that is different from the first wavelength, the second light emitting a graphical representation of a security code value that indicates authenticity of the authenticable digital code.

Abstract
An authenticable digital code includes a printable medium, a machine-readable digital code, formed on the printable medium, that graphically represent information, and at least one security signature positioned relative to the machine-readable digital code. The security signature includes a fluorescent material that, when excited by light of a first wavelength, fluoresces and emits light at a second wavelength that is different from the first wave length. Authenticity of the authenticable digital code is determined by detecting, when the authenticable digital code is illuminated by light of the first wavelength, light of the second wavelength at a position relative to the machine-readable digital code.

10. A system for authenticating an authenticable digital code, comprising:
-
a processor; a non-transitory memory communicatively coupled with the processor; a camera controlled by the processor and having a field of view; a light emitting display controlled by the processor that emits first light into the field-of-view of the camera; and software comprising machine-readable instructions stored in the memory that, when executed by the processor, are capable of; controlling the light emitting display to emit the first light of a first wavelength; controlling the camera to capture an image of the authenticable digital code positioned within the field of view and illuminated by the first light; analyzing the image to detect second light of a second wavelength resulting from fluorescence of a security signature on the authenticable digital code to determine a security code value; and decoding and authenticating the authenticable digital code based upon the security code value and the second wavelength. - View Dependent Claims (11, 12, 13)

14. A method for authenticating an authenticable digital code, comprising the steps of:
-
controlling a light emitting display to emit first light of a first wavelength; controlling a camera to capture an image of the authenticable digital code illuminated by the first light; analyzing the image to detect second light of a second wavelength within the image and resulting from fluorescence of a security signature of the authenticable digital code; determining a security code value based upon the second light; and decoding and authenticating the machine-readable digital code of the authenticable digital code based upon the second light and the security code value.
