Character Replacement Feature by Unplag Can Help Find Cheaters a Lot Faster

It’s not a secret for anyone, that a student willing to cheat on a test or exam is likely to be very inventive. No wonder that even automatic plagiarism finders cannot scare them. Why? The Unplag team found out that one of the simplest tricks played by a great many cheaters is character replacement.

How does it work in practice? A student chooses most frequently repeated letters, such as “a”, “o” or “e” in Latin and substitutes them either manually or automatically with their twins from other alphabet, for example Greek or Cyrillic. Yes, simple as that. Most similarity finders fail to spot these changes. Thus cheaters’ works will pass plagiarism tests successfully as if they were original ones. The goal is achieved.

That was the main reason why Unplag decided to add character replacement detection to its anti-cheating functionality in the first place.
