1. A method implemented on a processor, the method comprising: receiving, on a computer host, an electronic document representing a pharmaceutical prescription; identifying constituent regions that include at least a first portion and a second portion within the electronic document; identifying first spatial frequencies for the first portion within the electronic document; identifying second spatial frequencies for the second portion within the electronic document; identifying a header based upon the first spatial frequencies, wherein identifying the first and second spatial frequencies includes performing a fast Fourier Transform on a portion of a document and translating spatial information into frequency information such that (i) the header identifying the prescriber is identified from the first spatial frequencies; and (ii) the second spatial frequencies are analyzed using the profile of the identified prescriber; using the header to identify a prescriber; retrieving a profile specific for the prescriber; analyzing the second spatial frequencies using the profile specific for the prescriber such that the second spatial frequencies are compared to spatial frequency domain information from the profile specific for the prescriber, the prescriber-specific profile constructed from the prescriber's past records and including isolated handwriting of the prescriber in a spatial frequency domain; and creating, based upon results from analyzing the second spatial frequencies using the profile for the prescriber, a transaction record on the computer host for a medical transaction associated with the pharmaceutical prescription.
