Kim Dotcom threatens to sue Twitter, others over patent

Kim Dotcom says he doesn't really want to sue Google, Facebook, Twitter, and other companies, but he really needs some help funding his defense.

The eclectic and controversial MegaUpload founder today said he invented two-factor authentication, which is being used by more and more companies to secure access to their sites. The verification steps aim to reduce the likelihood of online identity theft, phishing, and other scams because the victim's password would no longer be enough to give a thief access to their information.

Along with Twitter's recent introduction, Microsoft, Apple, Google, Facebook, PayPal, and countless other … Read more

SoftBank gives U.S. right to OK Sprint board member -- report

In a further attempt to ease national security concerns over its proposed acquisition of Sprint, Japan-based SoftBank has agreed to give the U.S. government the right to approve one of the members SoftBank would appoint to Sprint's board of directors, according to a report.

How to enable Twitter's two-factor authentication

Going a week without a major brand having its Twitter account compromised was starting to become a rare occurrence. Critics and users alike repeatedly called upon Twitter to release two-factor (or step) authentication. The added layer of security requires you to enter your password, and then a subsequent six-digit access anytime you try to log into Twitter. The short code is sent via text message to your cell phone, which means that any would-be hackers would need to not only crack your password, but to also have physical possession of your cell phone.

Twitter, on Wednesday, finally rolled out its … Read more

On the second day of the company's I/O conference here on Thursday, Eran Feigenbaum, the director of security for Google Apps, suggested that people follow three recommendations to stay safer online.

UniKey Bluetooth door lock emerges as Kevo

Joining Apigy's Lockitron, the Kevo represents another attempt to link door-entry management to your smartphone.
