The cat and mouse game of plagiarism

In student surveys at colleges and universities, the percentage of respondents claiming to have committed an act of academic dishonesty is rising every year.  Among graduate students, MBAs are regularly the worst offenders.   A front-page recent NYT article discusses how colleges are fighting back.  Some schools are using electronic tools such as Turnitin.com that matches student papers against each other and against a huge inventory of web pages and published works.  Central Florida has built a high-tech testing center with cameras that record wandering eyes or attempts to photograph exam questions.  No one should be surprised that the same sort of tech tools used by students to plagiarize are now being turned against them.
