Plagiarism, the copying of another work for credit, is a serious offense and a problem many colleges face daily. Professors in the past had very limited options for discovering if an assignment had been copied. Today, however, the Internet has created several important tools that allow authorities to detect plagiarized intellectual property.
When a professor receives a student submission, he inputs it into a plagiarism detector. These software programs perform detailed checks automatically. While there are many different systems available, all operate in the same general way.
