Systems and methods for document authentication

A non-transitory, computer readable storage medium having a first memory section storing a plurality of enrolled document templates and a second memory section having instructions stored thereon that, in response to execution by a processor, cause the processor to:

• receive a first image of a subject identification document, the first image depicting, in a red-green-blue (RGB) color space, the subject identification document illuminated by ultraviolet (UV) light;
• transform the first image of the subject identification document to a second image of the subject identification document in a YCbCr color space;
• divide the second image into a plurality of regions of interest (ROIs);
• for each ROI, generate a color profile descriptor including first data elements associated with a number of pixels in each of a plurality of angular sectors in a CbCr color map of the YCbCr color space, within the corresponding ROI, and second data elements associated with pixel intensity of the pixels within the corresponding ROI;
• generate a matching score for the second image based on a comparison of the color profile descriptor for each ROI to a corresponding ROI of a first enrolled document template;
• and
• compare the matching score to a threshold to determine whether the subject identification document is authenticated.

A computer-implemented method for authenticating a subject identification document, the method implemented using an authentication system including (i) a memory storing a plurality of enrolled document templates, and (ii) a processor in communication with the memory, the method comprising:

• receiving a first image of the subject identification document, the first image depicting, in a red-green-blue (RGB) color space, the subject identification document illuminated by ultraviolet (UV) light;
• transforming the first image of the subject document to a second image of the subject identification document in a YCbCr color space;
• dividing the second image into a plurality of regions of interest (ROIs);
• for each ROI, generating a color profile descriptor including first data elements associated with a number of pixels in each of a plurality of angular sectors in a CbCr color map of the YCbCr color space, within the corresponding ROI, and second data elements associated with pixel intensity of the pixels within the corresponding ROI;
• generating a matching score for the second image based on a comparison of the color profile descriptor for each ROI to a corresponding ROI of a first enrolled document template;
• and
• comparing the matching score to a threshold to determine whether the subject identification document is authenticated.
