In privacy news, the data collection company LexisNexis is now estimating 310,000 Americans had their personal data stolen after the company’s computer systems were hacked. The figure is ten times higher than the company’s original estimate. LexisNexis collects and stores detailed personal information about nearly every person in the country. Meanwhile Tufts University has sent a letter to about 100,000 alumni warning them that their personal information may have been stolen from a computer database used for fundraising.
