Abstract
The disclosure includes a system and method to obtain at least one image of a document under test, wherein valid instances of the document under test include at least one perforation-based three-dimensional security feature; obtain a first image snippet from the document under test, the first image snippet corresponding to at least a first portion of the perforation-based three-dimensional security feature present in the valid instances of the document; analyze the perforation-based three-dimensional security feature for one or more characteristics; and modify a likelihood that the document under test is accepted as valid, or rejected as invalid, based on a presence, or an absence, of the one or more characteristics.
