Chase Card Services has dumped tapes containing millions of customers\u2019 details in a landfill site.The company will now have to tell 2.6 million current and former credit card customers of Circuit City that tapes containing their details were tossed out when they were mistaken for rubbish. Chase is apparently working with both local and national authorities to find out what happened, but it thinks they were in a locked box that was crushed and dumped in the landfill hole.There is no evidence that the tapes or their contents have been accessed or misused, the company said. And CEO Rich Srednicki issued a statement promising that: "The privacy of our customers\u2019 personal information is of utmost importance to us, and we take the responsibility to safeguard this information very seriously." Interpretations for what "very seriously" means are open to discussion.It\u2019s not the first time companies and banks have been careless with their customers\u2019 data. There have been several other recent instances of lost data tapes and inadequate data care:\n\nIron Mountain, demonstrating vulnerability to data loss a second time, lost tapes in April 2006, relating to 17,000 Long Island Railroad employees and other customers.\n\nCitiGroup lost data on 3.9 million customers in June 2005, when tapes being delivered by UPS went missing.\n\nA group of U.S. banks had 676,000 customer records stolen in May 2005.\n\nIron Mountain lost a box of backup tapes containing 600,000 current and former Time Warner employees\u2019 personal data in May 2005.\n\nCanadian company Simmons Mattress switched from Iron Mountain to EVault because, when Simmons was hit with a region-wide power blackout in August 2003, Iron Mountain, its disaster recovery supplier, was hit by the same blackout.-Chris Mellor, Techworld.com (London)Check out our CIO News Alerts and Tech Informer pages for more updated news coverage.
