MXI Security is offering a line of portable security devices that includes the Stealth MXP, a USB drive that not only provides password authentication, but biometric (i.e., fingerprinting) authentication as well, along with identity authorization. I caught a demo of the product at Interop, and it seemed to be a good solution for businesses that need portable security devices for, say, employees who work off-site, with the added attraction of up to 4 Gbytes of storage space for data. (And the drives have retractable ports, which are always handy.)
A somewhat different solution is being touted by EncryptaKey, which plans to make USB flash drives that include a biometric scanner, RFID, and Bluetooth, and which will be used to provide security for personal information and other sensitive data. According to Kelly Owen, the company's CEO, the 8-Gbyte drive will contain the Linux-based EK OS -- users will use this operating system, rather than the computer's, to transmit sensitive information to vendors and other partners, thus preventing any data theft caused by contamination of the host computer. The product is still in the development stage and will most likely be offered to enterprises first as a way to handle their own data security.
