Turnitin(又名Turnitin.com)，是一个建立在因特网基础上的抄袭探测服务，由iParadigm, LLC开发。部分机构(通指大学和高中)已经购买了上传许可证以上传论文并检测其抄袭程度。

自这个系统推出以来，学生可能会被学校要求将自己的论文上传到Turnitin，这个举措是一种对抄袭行为的威慑及警告。不过这种做法也引起了部分批评，一些学生拒绝这么做并认为这是一种假定犯罪的行为。此外，批评家指出这个软件的用途已经侵犯到教育隐私权和知识产权法。

上级公司iParadigm, LCC，也同时为报纸编辑、出版商推出了一项相似的服务叫做iThenticate，运行在信息网站Plagiarsm.org。其他Turnitin品牌产品则侧重于教育市场，例如判分，同行审查等服务。

功能

Turnitin通过采用专用算法对比上传文章和数据库文章来检测可能存在的抄袭现象。他能够扫描其本体数据库，也可以进入有协定(专利使用权转让协定)的大型学术数据库。

数据库

• 一个现存的拥有庞大数量的文档副本可在一个指定的网站里供查阅。该公司使用一个网络蜘蛛（webcrawler）不断的更新储存网络资源，除去robots.txt文件被排除在外；
• 数百万计的商业性书籍，报纸及杂志；
• 一千万份已经被提交至Turnitin的学生作业。

学生数据库

学生们提交的论文被储存在数据库中以检查抄袭。这一举措防止了学生之间互相抄袭的现象。一些支持者指出，在数据库中储存以往学生的作业保护了学生的知识产权(在某些情况下是大学的知识产权)不被之后的人所抄袭。然而，在另一些人看来，这种行为则侵犯了学生的著作权。

教室模式

教师可以将学生作业以“个别文件”，“大批文件”或“压缩文件”（ZIP）的形式提交至Turnitin.com。

Teachers may submit student papers to Turnitin.com as individual files, a bulk upload, or a ZIP file. Teachers can also set up the assignment analysis options so that each student can review their originality reports before their final submission. A peer-review option is also available, should instructors wish to use that service in their courses.

Some virtual learning environments can be configured to support Turnitin, so that student assignments can be automatically submitted for originality analysis. Moodle, WebCT, Blackboard and ANGEL all support Turnitin integration with course sections and assignments.

Turnitin acts as a tool for identifying matching text but is often not considered the final word on whether plagiarism has occurred. It is left up to teachers or professors using the service to decide if matching text identified by Turnitin is an unreferenced source, or mere coincidence, as opposed to outright plagiarism.

Criticism

While most people agree that combatting plagiarism is important, Turnitin critics argue that:

1. Turnitin violates student privacy and intellectual property rights, especially when archiving student papers without students' knowledge or permission;
2. Turnitin profits from students' work without paying royalties;
3. Turnitin creates an adversarial relationship between teachers and students because it fosters an atmosphere of distrust and renders students "guilty-until-proven-innocent";
4. Turnitin distributes copies of students' papers to third parties, which destroys the future marketability of students' intellectual property.

Response

In response to these criticisms, others have noted that:

1. Turnitin uses the papers only to check for plagiarism in a particular paper and to compare it against other submitted papers. It is not using the material as intellectual property.
2. Turnitin is paid a fee for this service, just as many other organizations in universities and other parts of society are.
3. Requiring submission is the surest way of deterring cheating.
4. A positive finding is the only beginning of a dialog between the faculty member and the student, as there are often innocent reasons why the finding happened.

Privacy

The U.S. federal Family Educational Rights and Privacy Act (FERPA) prohibits disclosing confidential information about students to third parties without their or their families' permission. Critics of Turnitin argue that sending papers to Turnitin without student permission thus violates their rights.

Turnitin claims its archiving of student papers complies with FERPA, since the statute only applies at two points: when it is transmitted to them, and when it is released from the data base when a match is found with another submission. In the former case it is not considered part of the educational record since it has not yet been graded, and in the latter it does not divulge personal identifying information. However, the Family Compliance Policy Office, the department of the Department of Education responsible for enforcing FERPA, has stated that institutions may submit student papers to Turnitin only if they remove all personally identifiable information from the papers.

The Student Union at Dalhousie University has criticized the use of Turnitin at Canadian universities because the American government may be able to access the submitted papers and personal information in the database under the U.S. Patriot Act. Mount Saint Vincent University became the first Canadian university to ban Turnitin's service partly because of implications of the U.S. Patriot Act.

Possible violation of student copyright

Since Turnitin archives all papers it receives and sells its services, including that database, for profit, it has also been charged with violating student copyright since students are not compensated for the use of their work. Turnitin founder John Barrie claims the company is merely making fair use of student work since, despite iParadigms profiting from the sale of the software, it is ultimately for educational purposes. The company also says the archiving does not detract from students' future ability to profit from their work, and in fact should even help them by guaranteeing its originality.

Lawyers for the company also claim that student work is covered under the theory of implied license to evaluate, since it would be pointless to write the essays if they were not meant to be graded. That implied license thus grants permission to copy, reproduce and preserve, it says. Dissertations and theses, the company's lawyers note, also carry with them the implied permission to archive in a publicly accessible collection such as a university library.

University of Minnesota Law School professor Dan Burk counters that the company's use of the papers may not meet the fair-use test for several reasons:

• The company copies the entire paper and not just a portion;
• Students' work is often original, interpretive and creative rather than just a compilation of established facts, and
• Turnitin is a commercial enterprise.

Presumption of guilt

Some students also argue that requiring them to submit papers to Turnitin creates a presumption of guilt, which may violate not only scholastic disciplinary codes but also applicable local laws and judicial practice. Some teachers and professors also support this argument when attempting to discourage their schools from joining Turnitin.

Litigation

In one well-publicized dispute over mandatory Turnitin submissions, a student named Jesse Rosenfeld at McGill University declined to pass his academic work along to Turnitin. The University Senate eventually ruled that Rosenfeld's assignments were to be graded without the use of Turnitin. In 2005 another student at McGill University named Denise Brunsdon who refused to submit her assignment to Turnitin.com won a similar ruling from the Senate Committee on Student Grievances.

In September 2006 students at McLean High School in the Washington, D.C. suburb of McLean, Virginia, organized a Committee For Students' Rights to protest the school's recent adoption of Turnitin. In addition to the presumption-of-guilt argument, the McLean students also claimed it was a violation of their intellectual property rights for Turnitin to archive their papers for future commercial use without compensating them. On March 27th, 2007, with the help of a pro bono attorney, a group of students from Mclean High School and Desert Vista High School (located in Phoenix, Arizona), filed suit in United States Circut Court (Eastern District, Alexandria Division), alleging copyright infringement by iParadigms, the parent company of turnitin.com.
