    摘要: An apparatus, method and system are disclosed for touch and gesture detection. A light source array comprises a plurality of light sources. Each light source of the light source array transmits a light beam across a face of a display in response to being activated. A light sensor array comprises a plurality of light sensors. Each light sensor of the light sensor array detects an intensity of each light beam transmitted across the face of the display in response to being activated. A controller concurrently activates each light source of the light source array with each light sensor of the light sensor array as a source/sensor pair during a detection cycle while other light sources of the light source array and other light sensors of the light sensor array are inactive. The controller further determines a location of a pointer relative to the display from a pattern of light beam intensities for each source/sensor pair.

    摘要: A method for managing shared passwords on a multi-user computer system is disclosed. A set of shared passwords and an administrator internal key are initially generated. After the receipt of an administrator external key, the administrator internal key is encrypted with the administrator external key. For each user level within the computer system, an internal key is generated by hashing the administrator internal key. For each user level within the computer system, each of the shared passwords encrypted with a respective one of the internal keys. The internal keys and the encrypted shared passwords are then stored in a non-volatile storage device.

    摘要: A method for providing a secure single sign-on to a computer system is disclosed. Pre-boot passwords are initially stored in a secure storage area of a smart card. The operating system password, which has been encrypted to a blob, is stored in a non-secure area of the smart card. After the smart card has been inserted in a computer system, a user is prompted for a Personal Identification Number (PIN) of the smart card. In response to a correct smart card PIN entry, the blob stored in the non-secure storage area of the smart card is decrypted to provide the operating system password, and the operating system password along with the pre-boot passwords stored in the secure storage area of the smart card are then utilized to log on to the computer system.
