On May 9, 2008, Iowa Governor Chester Culver signed legislation (SF 2308) requiring any person who owns or licenses computerized data that includes a consumer’s personal information to give notice of a breach of security. The law does not require notification if, after an appropriate investigation or after consultation with the relevant federal, state, or local agencies responsible for law enforcement, the person determined that no reasonable likelihood of financial harm to the consumers whose personal information has been acquired has resulted or will result from the breach. Following is an updated list of the 43 state security breach notification laws (plus District of Columbia and Puerto Rico).

Virginia, West Virginia, and South Carolina are the latest states to pass data breach notification laws, bringing to 42 the total number of states with such laws on the books (including the one state with a law that applies only to public entities, Oklahoma). Listed below are the 41 states with laws that apply to private entities (plus the District of Columbia and Puerto Rico).

Lawmakers in six states have responded quickly to the massive data breach at TJX Companies, Inc. with various bills designed to strengthen merchant security and/or render companies liable for third party companies’ costs arising from data breaches. These latest bills – introduced in California, Connecticut, Illinois, Massachusetts, Minnesota and Texas – represent a new front of state legislative activity to regulate privacy and data security and expand requirements beyond the current data breach notification and data security laws that many states have enacted in recent years. To date, Minnesota is the only state to enact such legislation, which was signed into law by its Governor on May 21, 2007.
