Your UDID As A Social Security Number
Up until now, advertisers and developers using iOS as a platform have had it great. Using UDID, they could follow your activity across multiple apps and put together a pattern of behavior which they could then sell to third-parties or use to show you more targeted in-app ads that you’d be more likely to tap on. And the reason that UDIDs make it easy to do this is because it’s a value that is uniquely associated with just one device that cannot be erased, duplicated or obscured.
So here’s the chain. The developer behind an app sells your UDID to an advertising network, which stores it on its servers. The more devs sell your UDID to that same ad network, the more that ad network knows about you, and the better it can serve you ads on that specific device. These ad networks can then sell their databases to other ad companies, who can put together a pretty complete picture using their combined UDID databases of what you use that iPhone for.
In other words, UDID is like a social security number. We give our social security number to companies all the time. In isolation, a company having your social security number is not necessarily a bad thing. But the problem with a social security number is that if it is leaked out into the world for whatever reason, people we don’t mean to have it can use it to dig up your medical records, credit card number, home street address and more.
If You’re Not Paying For The Product, You Are The Product!
The first thing to understand is that not all tracking — or even most — is insidious. A lot of the best things we take for granted about our iPhones and iPads, like free apps, are paid for by tracking.
There’s a saying in the privacy community: “If you’re not paying for the product, you are the product!” It’s truer on the App Store than anywhere. If you’re not paying for an app, you are usually selling yourself (with or without your knowledge) to an ad network, which will use your UDID to track and target you.
In the same way Facebook makes money by serving targeted ads to you based on what you like, mobile apps sell your finger taps so that ad networks can serve you targeted ads that compliment your tastes. The idea itself is not a matter of breaching your privacy, because you agree to use this stuff. Money has to be made somehow.
Online and mobile advertising has gotten exponentially more relevant for the end user over the last decade. Companies can learn what you like and tailor ads to your preferences. That’s usually a good thing for most people.
The problem is that UDID has the potential to be misused.
