Companies have six technologies to choose from when it comes to re-evaluating their laptop lockdown strategy. Biometrics, one of those fascinating concepts, is not practical when not built in into a laptop. Notebook computers from manufacturers such as Dell, Fujitsu and Hewlett-Packard, among others, are available with fingerprint readers as either a standard feature or an option. There are fewer projects being developed beyond fingerprints. A USB-pluggable, 3inch, 3-D face-recognition camera from BioScrypt faces the same challenges as other biometric solutions as it is not portable because it relies on an external camera. Smart Card Readers allow users to store passwords and other sensitive information. The cards are a standard feature on many business laptops sold by HP in 2006. Few firms are adopting smart cards because it is not practical to carry different cards for PCs and building access. The Trusted Platform Module is a standard feature from the Trusted Computing Group, which consists of Advanced Micro Devices, HP, IBM, Infineon, Intel, Lenovo, Microsoft and Sun Microsystems. It is an embedded security chip that is capable of storing keys, passwords and digital certificates. It can be used in tandem with portable tokens for laptop user authentication. BIOS (basic input/output system) Security is the most basic method of securing laptops. Users are prompted to provide a password before the operating system boots. In 2006, HP began integrating Disk Sanitizer into the BIOS of its portable computers. Encryption hardware from Seagate Technology secures laptops using encrypting hard-disk drives. Momentus 5400 FDE-2 hard drives featuring Seagates DriveTrust Technology will be available in April 2007 in ASI Computer Technologies laptops.
