Stylometry- This method is quite debated, the stylometry refers to comparing the style of the writing to its similarly written content.

Even if you have heavily re-written the sentence to avoid plagiarism, you still write some of the original phrase or words in the sentence, which initially results in plagiarised content.

Vector space- This model actually analysis the words and compare it to the original documents.

Because the tool only compares the given citation to the original documents, judging the citation will be the same in both of them.

Citation detection- This method only works with academic documents, especially when there are citations mentioned.

But it’s very useful when the content is not verified or it's just a blog post.

It requires more resources and more time, especially when you’re checking a gargantuan document.

String matching- In this method, the tools take a string of text from one document and try to find in different other documents.

So, when every content has a unique code, the plagiarism checker has to perform less processing to compare two identical works, which becomes very fast and accurate. It basically converts a huge file into a 32-character fingerprint to define its uniqueness.

Fingerprinting- A fingerprint of a file is actually a unique code that is set by the original document publisher.
