Abstract: Certain embodiments herein relate to authenticating access to an operating system by a user before the operating system is booted. Such authentication may be performed by processing information received from a wireless communication token via Near Field Communication (NFC), in one embodiment. The received information may be processed to determine credentials for accessing the operating system, which if validated, may be sent to a Basic Input Output System (BIOS) which may boot the operating system in response. The BIOS may also perform various other functions if authentication is successful, such as decrypting a hard disk on which an operating system is installed before booting the operating system. According to this configuration, a decryption key may be received from the wireless communication token and subsequently sent to the BIOS to enable the decryption and subsequent booting of the operating system.

Abstract: A system for powering up a computer having a central processing unit (CPU), which CPU includes an operating system (OS), when the CPU is in an Sx state in which the (OS) is not powered up. There is a near field communication (NFC) detector for detecting an NFC signal, and an embedded controller physically separate from said CPU, the embedded controller responsive to the NFC signal and adapted to power up the CPU out of said Sx state.

Abstract: A method for preventing copying a proprietary digital image data that is rendered within a window displayed on a computer monitor, including providing screen pixel data for rendering on a computer monitor, the screen pixel data including pixel data for a first window having proprietary digital image data therewithin, detecting that a second window is going to be displayed on the computer monitor, determining the position and size of the second window, determining, based on the position and size of the second window, a portion of the screen pixel data wherein the first window is going to be covered by the second window, and replacing the portion of the screen pixel data with substitute pixel data, prior to the second window being displayed. A system is also described and claimed.
