Do Breach Notification Laws Work?
According to Deirdre Mulligan, a professor of information technology law and policy at UC Berkeley's School of Information, a Ponemon study found that about 20 percent of respondents claimed to have terminated their relationship with a company after discovering that the company experienced a breach.
But a separate survey of companies found that the percentage of customers who actually do terminate their relationship with a company is less than 7 percent. Both numbers should be taken with a grain of salt, , however. Consumers, Mulligan told Threat Level, have a tendency to say they're going to do one thing when they actually do another, and companies also can't be relied on to honestly report the numbers of customers they lose from a breach.
