Authorship attribution is an important emerging security tool. However, just as criminals may wear gloves to hide their fingerprints, so authors may choose to mask their style to escape detection. Most authorship studies have focused on cooperative and/or unaware authors who do not take such precautions. Using a newly published corpus (the Brennan-Greenstadt Obfuscation corpus), we use the JGAAP system (www.jgaap.com) to test different methods of authorship attribution against essays written in deliberate attempt to mask style. We confirm that this is an issue.
