I think YOu people know about TPM (Trusted Platform Module) in Windows Vista .. which is a chip which are placed in the upcoming Motherboards..
THis Works with Bit locker and other securities for the system.
What is the Trusted Platform Module security hardware?
The Trusted Platform Module (TPM) security hardware is a microchip that enables your computer to take advantage of advanced security features, such as BitLocker Drive Encryption. The TPM is built into some newer computers. Check the information that came with your computer to see if your computer is equipped with the TPM.
A computer with the TPM can create encryption keys that can only be decrypted by the TPM. The TPM "wraps" encryption keys with its own storage root key, which is stored within the TPM. Storing the storage root key in the TPM chip, rather than on your hard disk, offers better protection against attacks designed to expose your encryption keys.
When you start a computer that has the TPM, the TPM checks the operating system for conditions that could indicate a security risk. These conditions could include disk errors, changes to the basic input/output system (BIOS) or other startup components, or an indication that the hard disk has been removed from one computer and is being started in a different computer. If the TPM detects one of these security risks, BitLocker keeps the system partition locked until you enter a BitLocker recovery password to unlock it.
