What is "writeprint"

Writeprint is a term proposed by some forensic linguistics researchers to denote a set of distinguishing stylometric characteristics of a written text ( writer invariants) such as " vocabulary richness, length of sentence, use of function words, layout of paragraphs, and key words" which allow one to identify its author (if written by a single person).

It is suggested that writeprints could provide forensics experts with a new tool for identifying criminals in a digital medium, much like a digital fingerprint.
