How to reference confidential data in reference list I'm writing my BA thesis in computer science at a larger company and need to reference a confidential statistics report that has been made available to me in my reference list.

So my question is, how does one normally cite a confidential source? I assume you would somehow include the contact details of someone at the company with access to the material?

I'm using the Vancouver reference style by the way. Cheers!

Edit: I should clarify that the confidential "report" that was made available to me really isn't a report, but rather just raw data. It doesn't have an author or even a title, only site visitor statistics, thereby my confusion on how to reference it.
Before you do anything with the confidential data, you should have cleared its use with the company in question. Giving away the data in any form without their express permission could get you into a lot of trouble.

That said, if the report containing the data is a internal company technical report, it should be cited as such in a bibliography. This provides enough information for a person to track it down, although you may want to state that it is not available to the general public.
