Data Breaches and Privacy Violations Aren't Just About Identity Theft

Chris Walsh over at the EmergentChaos blog had a piece the other day about some of the research they are doing on breach disclosures and what we can learn from them. I made come comments about data breaches as they relate to identity theft and at the time was pretty well convinced that what matters about data breaches is just identity theft.

After reading a follow-up comment from Chris and Dissent, and then the next piece by Adam -
It's not all about "identity theft" - I think I need to regroup.

Adam made the point that:

Data breaches are not meaningful because of identity theft.

They are about honesty about a commitment that an organization has made while collecting data, and a failure to meet that commitment. They're about people's privacy, as the Astroglide and Victoria's Secret cases make clear.

This is a very good point and one I'd lost site of in my previous comments. Protecting privacy is about the implied or explicit agreement between the data provider and the data repository/protector. A breach of this agreement constitutes a privacy violation, regardless of whether the law requires disclosure.

One of the problems with current disclosure laws is that their focus is entirely on identity theft. SB-1386 (and most if not all of the other disclosure laws) only kick in if your personally identifiable information and private identifier (bank account number, SSN, CC#, etc) is released as well. The end effect of this sort of disclosure regulatory regime is a focus not on privacy but on identity theft. As Adam rightly points out a lot of damage can be done through privacy violations without requiring the possibility of identity theft.

Adam listed two obvious examples of data disclosures that had nothing to do with identity theft but that nevertheless were violations of privacy agreements made between the data owner and the data custodian. Another would be AOL's release of search data.

I'm toying with a few thoughts on how you can modify the existing US regulatory regime without undesired effects. The US is distinctive from other the EU example for our relatively lax privacy regulation, but there are at least a few consumer friendly results that go along with it such as cheaper financing, etc. Trade-offs abound and we don't make decisions in an informed fashion about almost any of them. But more on that later when I have a little more time to think.

Peter Huber argues in Forbes that there is no "privacy" in our social security numbers or credit card numbers. The "secrecy" of those things does not really authenticate us. So this business of giving people lots of notices about compromise of their numbers seems pointless.
