WASHINGTON — The data breach at Target Corp. that exposed millions of credit card numbers has focused attention on the patchwork of state consumer notification laws and renewed a push for a single national standard.
Most states have laws that require retailers to disclose data breaches, but the laws vary wildly. Consumers in one state might learn immediately that their personal information had been exposed, but that might not happen in another state, and notification requirements for businesses depend on where their customers are located. Attorney General Eric Holder has joined the call for a nationwide notification standard, but divisions persist, making a consensus questionable this year.
"We're stuck with the state-by-state approach unless some compromise gets done at the federal level," said Peter Swire, a privacy expert at Georgia Tech and a former White House privacy official.
Despite general agreement on the value of a national standard, there are obstacles to a straightforward compromise:
—Consumer groups don't want to weaken existing protections in states with the strongest laws.
—Retailers want laws that are less burdensome to comply with and say too much notification could cause consumers to tune out the problem.
—Congress is looking at different proposals for how any federal standard should be enforced and what the threshold should be before notification requirements kick in.
The issue gained fresh urgency as part of a larger security debate after data breaches involving retailers Neiman Marcus and Target. Target, the nation's second-largest retail discounter, has said 40 million credit and debit card accounts were exposed between Nov. 27 and Dec. 15.
The company went public with the breach on Dec. 19, several days after it said it learned of the problem and soon after the news began leaking online. Since then, sales, profit and stock prices have dropped, the company's chief information officer has resigned and banks and retailers are facing continued scrutiny about what more can be done to protect consumer data.
