I've met with people and spoken at both Facebook's headquarters and Google's, and there is considerable interest in privacy by design. With regard to Facebook, if I had to guess their position, I would say they view privacy by design as being incompatible with their business model. That view is essentially, use as much information for as many purposes as you can, and then if you go too far—as they did with the news feed—then you can pull it back in terms of people's privacy preferences.
I have the greatest respect for Mark Zuckerberg. I've spoken to him. He totally gets that privacy is all about control, and I would suggest that he certainly values his privacy and controls it. But in terms of the business model, I think they would not be interested in it.
Google, on the other hand, is interested. If you look at Google+, which is their online social media, they have tried to incorporate privacy by design features. They invited me to speak to their head engineers, who were designing it, about privacy by design and how you incorporate this in terms of data minimization and making privacy the default. That was the concept behind “circles” and trying to minimize data collections.
I'm not going to oversell this. I think businesses will come to this gradually, if the business model is predicated on reaching as many people as possible.
Having said that, there is a way you can have online social media and privacy, and that's the Google+ experience in circles. I know many people who are on it. I don't know what the numbers are right now. I think they've exceeded 50 to 60 million, but we'd have to confirm that. It has an ability to restrict the information you share to the narrow audience that you want to share or speak with.
If I may, sir, I want to add one comment relating to your first question. With regard to the notion of minimizing data and collections and how you restrict it to the primary purpose, one example we did in my jurisdiction involved the creation of an enhanced driver's licence that could be used across the border instead of a passport.
They, of course, have to collect information. We put directly into the regulation what information, what personal identifiers, could be collected: the name, one's address. We said they should identify the fields specifically, as opposed to leaving it open-ended. We were able to do that. One way of trying to restrict the collection of personal information is by identifying specifically, very narrowly, that which you are permitting.
