Greetings, I'd like to share a research paper that attempts to estimate the effect of data breach dislcosure laws on identity theft. I'll be presenting it at this year's workshop on the economics of information security (http://weis2008.econinfosec.org). This is somewhat work in progress as we will be augmenting it with more data and additional analysis. However, I thought the group might be interested in what we've discovered so far. Title: Do Data Breach Disclosure Laws Reduce Identity Theft? http://weis2008.econinfosec.org/papers/Romanosky.pdf Abstract: Identity theft resulted in corporate and consumer losses of $56 billion dollars in 2005, with about 30% of known identity thefts caused by corporate data breaches. Many US states have responded by adopting data breach disclosure laws that require firms to notify consumers if their personal information has been lost or stolen. While the laws are expected to reduce losses, their full effects have yet to be empirically measured. We use panel from the US Federal Trade Commission with state and time fixed-effects regression to estimate the impact of data breach disclosure laws on identity theft over the years 2002 to 2006. We find no statistically evidence that laws reduce identity theft, even after considering income, urbanization, strictness of law and interstate commerce. If the probability of becoming a victim conditional on a data breach is very small, then the law's maximum effectiveness is inherently limited. Quality of data and the possibility of reporting bias also make proper identification difficult. However, we appreciate that these laws may have other benefits such as reducing a victim's average losses and improving a firm's security and operational practices. cheers, sasha romanosky http://www.romanosky.net _______________________________________________ Dataloss Mailing List (dataloss () attrition org) http://attrition.org/dataloss Tenable Network Security offers data leakage and compliance monitoring solutions for large and small networks.
