Authenticable digital code and associated systems and methods

A method for manufacturing an authenticable digital code, comprising:

• generating a code print image that graphically represents information of the authenticable digital code;
• printing the code print image onto a printable medium using one or more visible inks to form a machine-readable digital code;
• generating a security print image that graphically represents a security signature;
• printing the security print image onto the printable medium in a position relative to the code print image using 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 wave length, the second light emitting at a position relative to the machine-readable digital code for indicating authenticity of the authenticable digital code.

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 at a position within the image relative to the machine-readable digital code resulting from fluorescence of a security signature on the authenticable digital code;
• and
• decoding and authenticating the authenticable digital code based upon the position and the second wavelength.
