A group of computer scientists at the University of Washington has developed a way to make electronic messages "self destruct" after a certain period of time, like messages in sand lost to the surf. The researchers said they think the new software, called Vanish, which requires encrypting messages, will be needed more and more as personal and business information is stored not on personal computers, but on centralized machines, or servers. In the term of the moment this is called cloud computing, and the cloud consists of the data - including e-mail and Web-based documents and calendars - stored on numerous servers.

Chase Bank has sent out data breach notification letters to an undisclosed number of customers after a computer tape with customers' personal information was reported missing from a third-party vendor's storage facility. Tom Kelly, spokesperson for New York-based Chase, the commercial/consumer banking arm of financial giant JPMorgan Chase, says the vendor -- which he would not name -- confirmed it received and maintained the tape, and that its offsite facility had been searched thoroughly after the tape disappeared. Kelly would not say if the data on the tape was encrypted, but says its data can be read only with special equipment and software. "We have no evidence to indicate any of the information has been viewed or used inappropriately," Kelly says. A local ABC News station in Louisville, KY first reported the missing data tape and the notification letters being sent in August. Kelly says the notification letters are being sent out in batches, but would not say how long the tape has been missing, nor what type of customers' information (credit or banking) was on the tape. The electronic files, according to the notification letter, may have included names, addresses and Social Security numbers, but did not include any banking or financial information. Affected customers are being offered a free one-year subscription to the bank's identity protection program, Kelly says.

"As many as 68,000 members of CalOptima, the Medicaid plan for Orange County, California, may be at risk of identity theft and fraud after several CDs containing their personal information disappeared while in transit, the agency reported. "CalOptima's claims scanning vendor sent the electronic media devices to CalOptima through the U.S. Postal service by certified mail," the agency said. "On Tuesday, October 13, 2009, CalOptima discovered the apparent loss of the devices when the external packaging materials were delivered by the U.S. Postal Service without the box containing the devices." The missing discs include patient information such as names, addresses, Social Security numbers, diagnoses, and billing codes. CalOptima said it notified state and federal agencies of the breach on October 14, and posted an alert on its Web site on October 15."

No U.S. appeals court appears to have ruled on whether such an order would be legal or not under the U.S. Constitution's Fifth Amendment, which broadly protects Americans' right to remain silent.
