Under legislation recently proposed in California, retailers doing business in the state would be subject to enhanced data destruction requirements, and all businesses would be affected by new data breach notification requirements.  In the wake of the TJX Companies data breach, which may have affected more than 46.2 million credit and debit cards, California Assemblyman Dave Jones introduced revised A.B. 779.  That legislation reiterates that retailers are subject to the same data safeguard requirements as other businesses that maintain customer records or own or license personal information, while significantly truncating the period of time retailers may retain personal information of customers.  The bill also would revise the data breach notification laws applicable to all businesses that own or license personal information.
