Systems and methods for detection of counterfeit documents

A system for detecting a counterfeit item, comprising:

• a contactless scanner for contactlessly scanning at least a portion of an item to generate a scanned image of the at least a portion of the item, wherein the at least a portion of the item comprises a visible graphic that comprises a plurality of human visible lines;
• and
• at least one processor, memory, and one or more programs stored in the memory for execution by the at least one processor, the one or more programs comprising instructions for:
• identifying at least a portion of the plurality of lines in the scanned image,
• determining a first characteristic of at least one line of the plurality of lines;
• identifying a type of the item based on the first characteristic of the at least one line;
• determining at least a second characteristic of the at least one line, the at least a second characteristic being different than the first characteristic and comprising line thickness and/or spacing of the at least one line, to generate at least one line thickness and/or spacing measurement, and
• determining whether the item is counterfeit based on a comparison between the at least one line thickness and/or spacing measurement and at least one reference line thickness and/or spacing measurement that is associated with an authentic version of the item,
• wherein the system is configured to generate an alert indicating a detection of a counterfeit item in response to determining that the item is counterfeit.
