摘要： A fingerprint verification method having band detection is provided. In one embodiment, the method includes capturing a fingerprint image and processing the image to determine if it includes bands attributable to changes in illumination intensity during image capture. If such bands are detected, the method preferably aborts the creation of a fingerprint template. Otherwise, if this and other security screens are passed, the method preferably includes the creation of a fingerprint template which may be compared to a stored fingerprint template to verify user identity. If such verification is established, the user is granted access privileges. One embodiment of a system implementing this method includes a fingerprint scanner for capturing fingerprint images, and an interface card having a digital signal processor (DSP) or other suitable mechanisms including software or electronics for processing the fingerprint images and generating a fingerprint template representative of the images. The system may further include a general purpose computer coupled to the interface and configured to receive the fingerprint template. The general purpose computer can then use the fingerprint template to verify the identity of the user.

摘要： A computer system includes multiple controllers that assist in executing the Power-On Self Test (POST) sequence to minimize the time required to complete system initialization. By shifting some of the responsibilities for executing the POST sequence to other controllers within the system, the testing and initialization of system devices can proceed concurrently. The controllers interface with peripheral devices, and include a register set that includes command information for initializing the testing and initialization of associated peripherals. The register set also includes dedicated bits for indicating the status of testing and initialization cycles, which can be read by the CPU to determine if testing or initialization is in progress, if it has completed, and if any errors have occurred. The register set also includes a configuration register for indicating configuration information and operating parameters of the initialized drive or peripheral. By distributing the testing and initialization responsibilities to the controllers, execution of the BIOS system software or system initialization software can be expedited, thus minimizing down time caused by initializing the computer system.

摘要： A method and system of interchassis and intrachassis computer component command and control. The existing power rail is used for network connectivity for intrachassis command and control. An existing common power mains can be used for interchassis command and control. Further, a protocol, for example, the Consumer Electronic Bus (CEBus) protocol (or a CEBus protocol modified for the particular power rail) can be used to provide interchassis and intrachassis platform management functionality. This management functionality is similar to that provided by the proposed Intelligent Platform Management Interface (IPMI) specification. A chassis bridge controller is used to interface the intrachassis power rail command and control infrastructure to an exterior network. External systems (interchassis communications) can communicate to the bridge via the particular protocol over an existing common power mains as a secondary channel exterior network. However, the management functionality is implemented intrachassis, that is, it is applied to the internal components of the machine.

摘要： In a computer system having a receiving computer and a source computer, a method for the remote flashing of the BIOS in the receiving computer including the steps of transferring the flash information from the source computer to the receiving computer, with the flash information including the flash code, the flash code instructions and an encrypted digital signature corresponding to the flash code. The receiving computer is operably placed in a secure mode. A hash value corresponding to the flash information is calculated, and the hash value from the flash information is decrypted. The flash code is validated by comparing the decrypted hash value of the flash information to the calculated hash value, and if validated, the BIOS if flashed with the new flash code.

摘要： A computer system that automatically and securely executes registered programs immediately prior to a transition to a reduced energy consumption state. A registrar table specifying registered programs and a secure modification detection value for each registered program are maintained in system management mode memory or other secure memory space in the computer system. A system management interrupt is generated following a request to remove power from the computer system or the occurrence of an event that triggers an energy saving mode. The system management interrupt handler routine then generates a current modification detection value for each registered program. The current modification detection values are compared with the secure modification detection values. Execution of a registered program is permitted if the values match. After all registered programs have been executed, the computer system automatically powers down or enters an energy saving mode. The computer system thereby allows secure and convenient execution of programs or commands that would typically interfere with normal computer use.

摘要： A secure start-up system for a computer enables a flash memory to be reset in a secured way. Various operations are carried out to make sure that the reset is an authorized one, and to avoid unauthorized, e.g. virus, infiltration. These operations include multiple tests to avoid the probability of the reset being unauthorized. Any one or more than one of the following can be used. Flashing is only authorized when a special flash enable bit is set in the non-volatile memory. This flash enable bit is reset during every startup cycle. Flashing is only authorized from a cold boot as opposed from a warm boot. This minimizes the possibility of a computer routine authorizing flashing by a software reset. Flashing is only authorized from a floppy. This prevents a virus from writing the flashing routine to the boot sector of a non-removable disc. The user is warned prior to flashing, and asked to confirm. Finally, contents of the flashing routine can be checked using some kind of checking algorithm such as a secure hash algorithm.
