Abstract: Methods and apparatus are disclosed to protect an operating system booted by a client computing device and provided by a server computing device. One such method includes requesting a trusted platform module of the client computing device to unseal a sealed encryption key, and receiving an encrypted operating system via a network in response to initiating a boot process of the client computing device. The illustrative method also includes decrypting the encrypted operating system received via the network using an unsealed encryption key obtained in response to requesting the trusted platform module to unseal the sealed encryption key, and executing the decrypted operating system.

Abstract: A method, apparatus, and articles of manufacture to perform speech to text conversion are disclosed. One example method of performing speech to text conversion at a first location includes determining an identity of a speaker, accessing a directory to determine a location at which speaker dependent training data associated with the speaker is stored, loading speaker dependent training data associated with the speaker, and performing speech to text conversion using the speaker dependent training data associated with the speaker.

Abstract: According to one embodiment, an apparatus is presented. The apparatus includes a storage device, a hypervisor, a plurality of partitions mapped by the hypervisor, and a key created by the hypervisor to prevent one of the plurality of partitions from accessing a protected block range of the storage device. In one embodiment, a disk controller is coupled to the plurality of partitions to interface with the storage device, and the disk controller is programmed with the key in order to restrict access to the protected block range.
