Systems and methods for token authentication

A method comprising:

• obtaining text on a document and a location associated with a steganographic image on the document, the steganographic image being among a plurality of steganographic images on the document;
• generating a first message authentication code based on the text and a secret key;
• determining, based on a date of the document, a first wavelength selection corresponding to a first wavelength range to use with a scanner to scan the document;
• obtaining, via the scanner, a second message authentication code based on (i) the location and (ii) the scanner scanning the steganographic image using the first wavelength selection corresponding to the first wavelength range;
• and
• authenticating the document based on a determination that the first message authentication code corresponds to the second message authentication code.

One or more non-transitory computer-readable media comprising instructions that, when executed by one or more processors, causes operations comprising:

• obtaining text on a document and a location associated with a steganographic image on the document, the steganographic image being among a plurality of steganographic images on the document;
• generating a first authentication code based on the text and a secret key;
• determining, based on the text of the document, a first wavelength selection corresponding to a first wavelength range to use with a scanner to scan the document;
• obtaining, via the scanner, a second authentication code based on (i) the location and (ii) the scanner scanning the steganographic image using the first wavelength selection corresponding to the first wavelength range;
• and
• authenticating the document based on a determination that the first authentication code corresponds to the second authentication code.
