Universities are required to adopt a system to ensure that the student who is enrolled in a course is the same who attends it, who submits homework, who takes the tests, who gains credits, and who finally graduates.
In general institutes outsource this process to affiliated companies of tutoring services (Proctoring), where students have to take tests on online computers.

The Higher Education Opportunity Act of 2008, Part H

Program Integrity, requires online schools to identify students who register, do the work and receive credits. 

Identification (login ID & PW)                                                                      PassWord Vault application

Activities registration                                                                                                    LogBook application

Thanks to the PassWord Vault application for Bio-Pen, students will sign in and certify their identity from home, creating a record of the test for a third part.
