Viper Plagiarism Checker: Posting Your Essays on Essay Mills

14

Viper LogoBack in 2010, I wrote a review of the Viper Anti-Plagiarism Scanner and, to put it modestly, I was not impressed. I found the service, which can be found at ScanMyEssay.com, to be slow, poor at detecting matches and generally far less useful than similar services.

Like most ineffective plagiarism detection services, I quickly forgot about it and moved on. However, it appears that it may have been a mistake.

Last week, Zulfiqar Ali Khan, a researcher at the Syed University of Engineer, wrote me seeking help getting a paper of his removed from an essay mill website (a website dedicated to posting copies of essays for students to use and often plagiarize from). When the paper eventually came down, the site involved explained that all of the content on its site was sourced from the Viper Anti-Plagiarism Scanner. They provided a link that indicated how that happened.

In short, the terms of service of Viper make it so that every single essay checked through it is, eventually, posted on one of a network of essay mill sites and there is nothing that the rightsholder and creator can do about it.

But while Viper does openly admit to doing this, their claims of being “transparent” ring hollow as the information is well-hidden on their site and it’s possible, if not likely, most people using the service are unaware that Viper is feeding their essays to various sites with the intent of making the available for others to use.

Unfortunately, this is just another cautionary tale about working with questionable plagiarism detection services and the dangers that they can pose.

What Viper is Doing

Viper, like most plagiarism detection services, has a terms of service. While most of the TOS is dedicated to your license to use Viper and its software, a section entitled “Store and Use of Your Documents” deals with the license you grant Viper in the work you submit.

That section, in turn, mentions the following:

When you scan a document, you agree that 9 months after completion of your scan, we will automatically upload your essay to our student essays database which will appear on one of our network of websites so that other students may use it to help them write their own essays. You agree that any right you may have to remuneration for such use of documents is waived. You may not use the Viper Software to scan documents for which you do not hold sufficient intellectual property to be able to authorise us to use the documents in accordance with the terms of this licence.

It then also provides a link to the page above, further explaining its policies.

What this means is that, once you submit an essay to Viper, first it is immediately stored in its database for later comparisons. This part is fairly mundane and is done by other plagiarism detection services.

However, after 9 months, the essay is then posted on a public website for students to use. These sites, often called essay mills, claim to be study aid tools but are widely used by students seeking to find essays to plagiarize in their own coursework.

In short, 9 months after using Viper in a bid to prevent plagiarism, the essay will appear on a website where students will likely be looking for content to plagiarize themselves.

Questionable Transparency

While Viper claims that it is being transparent about the use of your content, to me, that is debatable.

There’s no mention of this policy on the front page of their site and, as I tested earlier, it’s possible to go through the entire process of setting up an account, downloading and installing the Viper software without being clear.

in fact, the only time it’s mentioned at all is when you agree to the terms of service, but even then, it isn’t mentioned explicitly.

Even then, you have to be sure to click through to the TOS and read it. Nowhere is there a clear statement that submitting your article allows them to republish it, on an essay mill site no less.

Unfortunately, according to studies, only 7% of people actually read the TOS

and many of those who do may still not have seen it as the information (other than a warning at the top) is near the bottom.

By those numbers, at least 93% of people who use Viper are, most likely, completely unaware of how their essays are being used.

Legal Questions

This raises the question where this type of contract is legal and, if so, what can be done about it?

Generally, the courts have upheld clickwrap licenses and contracts. This is how most TOSes are enforced. However, as the EFF pointed out in a whitepaper in 2009, it isn’t as simple as getting the user to click “I Agree”.

The fact that the TOS link is displayed next to the tick box (instead of the tick box being at the bottom of the TOS itself) and the unusualness of the license may hinder the users’ assent, or agreement, of the contract. While it’s unclear, there are reasons to think that, in the U.S., there could be legal challenges.

However, Viper is based out of the UK so such questions about U.S. law are largely irrelevant and my knowledge of UK law is severely limited in this area.

That being said, there is another legal question: What happens when a user uploads an essay that they did not create or hold the copyright in? Since they are not the copyright holder, they have no ability to agree to the license and waive those rights.

While it’s true the Viper TOS forbids the uploading of essays not created by the user, as we just stated, most users probably didn’t even read the TOS. Since using plagiarism detection tools to check the work of other people is an extremely common use, if not the most common, many of the essays Viper is sourcing are, most likely, infringing the rights of the author.

This is further muddied by Viper itself, which, on its “Universities” page, actively encourages teachers, who are not copyright holders, to submit the work of students. Theoretically, this would be a violation of their own TOS and would make the use of the students’ essays on essay sites an infringement.

However, even with the contract and ethical issues set aside, this is a terrible way to source essays. Not only is there no check for quality, but you have no way to be 100% sure that you have a clear license to use the content.

Bottom Line

What it comes down to is this: An anti-plagiarism service is using the essays submitted to it to feed sites that are widely used by plagiarists seeking content to copy. To do this, they are using a TOS that, most likely, only a fraction of their users have read and are purporting to be transparent about the process.

While it’s very possible that Viper has improved, from a quality standpoint, in the years and versions that have passed since I reviewed it, this is unconscionable. While I understand that plagiarism detection firms need to make money and it’s a tough market to thrive in, this is, in my opinion, not an acceptable way for such a company to do business.

There are many excellent plagiarism detection alternatives out there ranging from free to expensive that do not do this and most offer much better detection.

I would advise anyone who cares about the work they produce, to go with one of those.

  1. Viper also begins sending you emails encouraging you to purchase papers from their database soon after you use the system. In my 2010 test, Viper came in last: http://plagiat.htw-berlin.de/software-en/2010-2/s10-45-viper/

    I do not agree that there are “many excellent plagiarism detection alternatives out there”. We need to get away from the notion that there is some kind of magic software that can detect plagiarism, as the test 2013 has again shown: http://plagiat.htw-berlin.de/software-en/test2013/

    Especially for universities, an ounce of prevention is worth a pound of cure. We need to educate about good writing practices and not rely on software systems that suffer both from false positives (plagiarism “detected” where there is none) and false negatives (no plagiarism found for a text that is, in fact, plagiarized).

    • Dr. Weber-Wulff,

      I didn’t realize that it was doing that. I never received any email from them. Either they never messaged me or they were filtered out, either way, thanks for the additional heads up.

      I should have clarified that statement to say “many excellent plagiarism alternatives out there compared to Viper”. I agree that there’s no magic bullet but the point I was trying, and failing, to convey is that there are many services better than Viper, which your tests seem to agree with.

      Also agreed on the prevention being more valuable than cure. I’ve spoken on that before but it’s a point well worth repeating and thank you for doing so…

  2. I’m a new instructor and looking for a plagiarism checker. You mention in this post there are other good alternatives to Viper. Which ones would you recommend?

    • For an instructor, I’d first tell you to see if your school has a Turnitin account. It may well and, if so, it’s going to be the best choice. Turnitin. has access to databases and information that other checkers don’t.

      Failing that, look into Copyscape (http://www.copyscape.com). It’s reasonably cheap, about 5 cents per search, and has very good matching. However, it doesn’t have access to academic databases not available to Google.

      • Hi Jonathan,

        it seems that your are an expert in this field. I know that maybe 60% of US students are using ithenticate while studying. But I heard that Turn it in and ithenticate are stealing your work into their database. I think this is unfair. My coleague adviced me Viper (Scanmyessay), but after your review I don’t think I want to try it 🙂 Also I heard that https://unplag.com/ is a new player in the market of plagiarism checkers. What can you tell about them?

        Thank you!

  3. Abstract: For smart living, interactive applications are increasingly important especially on interaction of people and the environment. The aim of this paper is to develop an android based application which will help the doctor to diagnose the diseases using their smart phone. Wireless technologies are bringing about dramatic improvements in the quality of patient care by allowing unprecedented mobility while providing medical staff with easy and real-time access to patient data. In this research, a new wireless patient monitoring system is developed from concept to a reality. After receiving the raw signal we can use digital filtering for extraction of wanted signal. After filtering it is processed for detecting diseases and thus output is display on the screen. The web module also connects the microcontroller and android OS together. Since this application is made on android platform which is an open source and independent of any platform, it can be installed on any smart phone. Using this new system, medical staff can track patients’ vital signs from any place, allowing them to monitor more patients. The accessibility of this application is simple and easy. By developing this application, we can say that, it can be cost effective, compact and user friendly.
