Apologies if this has already been answered: but I could only find questions relating to paper citations and grants in relation to double-blind reviews on academia.
If you are submitting a paper to a double blind review, are you permitted to talk about the source of your data-set at length if it is not publicly available? This may include, for instance, mentioning the company name and/or country of origin.
For instance, imagine being given a data-set by IBM in its European wing and you make your paper based on this data. Is it legitimate to name the origin if you are not directly identifiable?
