Résumé	Mosaic plagiarism, also called patch-writing, occurs when an author mixes copied phrases and sentences from a source with original text, rearranges material from multiple sources, or interweaves paraphrased and verbatim passages without proper citation or quotation marks. It is difficult to detect because the copied portions are interspersed with original writing, creating a surface appearance of original work.	Turnitin and iThenticate are commercial text-matching software tools used by educational institutions and academic journals to screen submissions for potential plagiarism. Turnitin is designed for student assignments; iThenticate is designed for researcher manuscripts. Both tools compare submitted text against billions of sources (web pages, academic databases, previously submitted documents) and generate a Similarity Index showing what percentage of the submission matches existing sources. These tools are screening instruments, not plagiarism detectors—they flag suspicious content for human review.
