Senators block vote extending NSA dragnet powers

Four U.S. senators ground the chamber's business to a halt Wednesday in an effort to prevent voting on a bill that would extend a law that's legitimized the National Security Agency's bulk collection of telephone and business records.

E-paper gives payment cards ever-changing security codes

That so-called security code on the back of your credit card offers limited protection from fraud since cybercriminals have figured out how to capture it from payment terminals. But now Oberthur Technologies is embedding an e-paper display in cards that replaces the printed 3-digit code with a small screen, where the code changes periodically.

Former Radio Shack customers should probably set spam filters to 'high'

After a lengthy legal tussle, bankrupt Radio Shack will be able to sell some customer data that it had listed among assets it sought to liquidate. Attorneys for 38 states that had objected to the sale have now agreed to a settlement that forces Radio Shack to destroy a good deal of the information. The New York attorney general hailed the deal as a victory for consumer privacy and one that creates a model for how to protect troves of personal data when companies go under.
