Aug. 14 (Bloomberg) -- Bloomberg’s Paul Kedrosky explains the technology behind Facebook’s new mobile advertising tracking and how it impacts user privacy. He speaks on “Market Makers.”

They are not yet.

Facebook is not charges much for a mobile ad as it does for desktop at.

To this new tracking feature be the way to get there?

Yes.

The problem is fundamentally that it is difficult to make the connection between being exposed on a mobile lab and taking action on that ad.

It is much more difficult to actually do anything about an ad you see on mobile.

Was that their ad that cause you to go into a store or go to your desktop and make a purchase?

The idea is to bridge that gap and make the connection and allow facebook to charge more for the mobile ad.

Ok, because that is the question i have.

I'm not sure how much insight you have into the engineering and mechanics of this tracking feature.

How can facebook -- let's say i am running a company and they put a mobile lab into, on facebook and it appears in people's newsfeeds and somebody clicks on that ad and then subsequently makes a purchase somehow -- how does facebook know that the purchase was made?

Facebook cannot know whether i buy something on amazon for example.

Yes, it can in a sense.

Here is how it sort of works.

Facebook has the luxury of having you log in.

They have a lot more information about what you actually do.

Not just these little euphemistic bits of technology that are used to keep in and what you are doing, but they have much more fine-grained information using your login presence on facebook.

If you combine that with trackers and little bits of information they post to your computer, they have an idea what exactly you are doing, what ads you are exposed to, and what action you took as a facebook user on another machine.

Your login information will provide information about what other things you do.

Just because i'm i look at an avenue mobile phone and i might buy it on my desktop, why should the mobile phone and get the credit?

That is the way the advertising industry works.

You take credit for everything you expose people to.

If they buy something come you say, it was me, it was me, it was me.

The problem is that advertisers have no idea whatsoever right now.

So often, people change during the day.

By even making a connection, however tenuous between what you are exposed to as a login facebook user and then what action you took on desktop, there is more information.

That is one of the big complaints in one of the reasons why they were relatively thinking mobile ads were less expensive.

There are all sorts of privacy concerns for many people.

Why?

Why shouldn't i expect -- facebook has done all kinds of things to upset people when it comes to privacy.

Shouldn't i expect facebook -- knowing how important mobile ads are to facebook, shouldn't i expect facebook to be doing this and perhaps even more, so long as nobody knows who i am?

So long as the data are anonymous and aggregated, isn't that ok?

To a point.

There is that old silicon valley adage that if you are not paying for product, you are the product.

You are not paying for facebook, so i must be the product.

I must not imply not much when they buy me in so me to an advertiser.

That should be my expectation.

At the same time, all of this aggregated metadata about my activities and purchases is all well and good in isolation, but the risk is you can build a fine-grained picture of me and then we start worrying about other forms of data that are escaping or data leaks or other intrusions.

It becomes an incredibly granular picture of everything about me and what i am doing.

It is this idea of how data leaks out and -- in intentional and unintentional ways.

It is one of the risks you place -- take when you stay logged into a social service all day long.
