Maybe I should have mentioned that in the answer to the earlier question from Mr. Green, I believe, on future issues to look at. This is a good example. I would want to learn more about the specific technical aspects of it.
You had a discussion, I believe, with Mr. Therrien on that. It came through that there is potential in that. There's potential for it to be a very useful and very effective tool, perhaps more so than SIN numbers and other such things, but there are also risks in terms of privacy.
This is an example where you would want to have a strong privacy impact assessment, ensuring how this is used, how safe it is and how the information is going to be contained. Again, it's reaching that public interest benefit for Canadians but not at the expense of privacy.
