When someone else’s content is used without their consent, plagiarism is considered intellectual theft and fraud. It does not give any acknowledgment (either mistakenly or intentionally) to the original author of the work, which is unacceptable. Plagiarism is also defined as the unlawful reuse of previously published content and the passing off of that content as original work.

A Plagiarism Checker is an application that can be downloaded and used to verify a document or a portion of a document for plagiarised or duplicate content. It is available online.
