[Building Sakai] Reaction: Sakai course on CD

[Michael Feldstein]

Maybe I'm missing something here, but it seems to me that, as long as 
the test is being taken in a non-proctored environment, the risk that 
somebody will just copy the questions by hand, look up the answers to 
the questions on Google, etc., are much greater than that somebody is 
going to crack your encryption. This is true whether the test is hosted 
locally or remotely. I don't see a technical solution to this particular 
security problem.

We looked at this for a project that allowed a student to "detach" a personal learning environment from the parent VLE, and where the student could take some content offline with them.  We chose not to allow answers to be taken offline in a form where they could be used by the PLE.  Our rationale was that, sooner or later, the answer would exist in unencrypted form in the machine's memory; that we had no control over what was looking at that memory (for example, the PLE could be running inside a virtual machine that could be inspected); and that therefore we could not guarantee the security of the answers against disclosure.
