In August 2010, the Privacy Rights Clearinghouse published its latest Chronology of Data Breaches, which showed that since 2005 more than a half-billion sensitive records have been breached. Of those breached records -- which contained such sensitive data as customer credit card or social security numbers -- approximately one-fifth came from retailers, merchants and other types of non-financial, non-insurance-related businesses, the majority of which were small to midsized.
