“Taking over the ideas, methods, or written words of another, without acknowledgment and with the intention that they be taken as the work of the deceiver” is a quotation defined by American Association of University Professors in 1989 for Plagiarism. As the above quotation states, plagiarism has been traditionally defined as the taking of words, images, ideas, etc. from an author and presenting them as one’s own. It is often associated with phrases, such as capturing of words, ideas and literary theft. Plagiarism can manifest itself in a variety of ways and it is not just confined to student papers or published articles or books. For example, consider a scientist, who makes a presentation at a conference and discusses at length an idea or concept that had already been proposed by someone else and that is not considered common knowledge. During his presentation, he fails to fully acknowledge the specific source of the idea and, consequently, misleads the audience into thinking that he was the originator of that idea. This, too, may constitute an instance of plagiarism. A small number of students, about 10%, admit that they started plagiarizing because of the Internet 3. This research studies about the concept of plagiarism with respect to internet to find the originality of a student or an author, who made a publication. It also proposes an idiosyncratic tool for identifying plagiarism of a key document by comparing the similarity of the key document with the documents in the internet pool and the results will be provided in terms of similarity percentage. This tool will be used to decide the integrity of a student or an author, who published an article by scanning through the documents available in the web.
