These slides, from a presentation at the ICAS 2013 workshop, propose methods which can be used to detect student cheating in tests and assignments. They use computer systems that are both intelligent and context-aware. Three particular problems are explored, including contract cheating using auction and agency web sites, cheating using social media groups, and the issue of essay spinning, where automated translation sites can be used to change the appearance of a document and beat current plagiarism detection systems such as TurnItIn. The presentation is intended to further enhance the discussion in this area. A video version of this presentation can be accessed at http://thomaslancaster.co.uk/blog.
