1. A system comprising: a non-transitory physical data store configured to store authentication information for physical documents enrolled with the system, wherein the non-transitory data store includes first authentication data representative of a most recent prior submission of information regarding a first physical document to the system; a hardware processor in communication with the non-transitory data store and configured to: receive an authentication request including a subsequent submission of information regarding the first physical document; apply an authentication algorithm to the information of the subsequent submission to generate additional authentication data for the first physical document, wherein the additional authentication data is indicative of observed wear on the first physical document during a time period between the most recent prior submission and the subsequent submission; determine an acceptable degree of difference between the first authentication data, representative of the most recent prior submission, and the additional authentication data generated from the information of the subsequent submission, wherein the acceptable degree of difference is determined based at least in part on an expected wear level associated with the first physical document during the time period between the most recent prior submission and the subsequent submission; compare the first authentication data with the additional authentication data to determine that the observed wear on the first physical document since the most recent prior submission conforms to the acceptable degree of difference; and transmit an indication of successful authentication.
