1. A system for identifying a source document from an image, comprising: a processor; a memory device including instructions operable to be executed by the processor to perform a set of actions, configuring the processor: to obtain an image of at least a portion of a document; to process the image to determine a plurality of image characteristics of the image, wherein the plurality of image characteristics comprise a first image characteristic representing ascending letters in the image, a second image characteristic representing descending letters in the image, a third image characteristic representing a number of letters in a word in the image and a fourth image characteristic representing a number of words in a line of text in the image; to compare the plurality of image characteristics to document characteristics of a first previously stored source document and a second previously stored source document, wherein the document characteristics comprise a first document characteristic representing ascending letters in a document, a second document characteristic representing descending letters in a document, a third document characteristic representing a number of letters in a word in a document and a fourth document characteristic representing a number of words in a line of text in the document; to select the first source document based at least in part on the image characteristics and the document characteristics; and to send information about the first source document to a user.
