摘要:
When a disk sector is written to, a bit for the sector is set indicating that the sector will require secure data disposal (SDD) to be run on it. To save time during end of life disposal, SDD is executed only on sectors whose bits indicate that they have been written to. SDD can be executed on each dirty sector in one operation at end of life or incrementally during use as disk activity permits.

A “setmax” command is issued in BIOS to hide the service area (HPA) of a HDD during normal operation, so that the HPA cannot be accessed or erased inadvertently by the user or by a virus. Pressing a special key (e.g., F11) during booting permits access to the HPA.

An apparatus, system, and method are disclosed for rapid wireless network association. The apparatus includes a logic unit containing a plurality of modules configured to functionally execute the necessary steps of conducting a preliminary full band search on a predefined frequency spectrum to identify the frequency of an active communication channel, investigate the availability of the active communication channels identified during the preliminary search, and associate with a wireless network device on the available active communication channel. These modules in the described embodiments include a search module, an investigation module, and an association module. Beneficially such an apparatus, system, and method provide for more efficient searching, scanning, and association than typically found in wireless networks.
摘要:
A client computer is connected via a network to an anti-virus server. A signal from the anti-virus server notifies the client computer that an anti-virus needs to be immediately downloaded from the anti-virus server. The client computer disengages from the network, and re-establishes a link with only the trusted anti-virus server. The anti-virus fix is installed, the client computer re-booted, and the client computer is then allowed to reconnect to the full network. If the client's primary operating system (OS) is infected, a secondary OS in the client computer performs the anti-virus download and execution. The disengagement from the network is performed by applying a filter in a network interface card (NIC) driver by the primary OS, the secondary OS, a service processor (SP), or by a virtual machine manager (VMM), depending on which is available at the client computer.

A secure computer system includes a central processing unit in which plural programs reside. The system includes means for verifying whether the at least one program is trusted or not trusted. That means can be an external key device that includes a verification program that can communicate with the programs residing within the central processing unit.
摘要:
A method and system is described for remotely managing a battery powered client computer. A data packet, which includes a set of instructions, is sent to the client computer from a managing computer. Included in the data packet is a field indicating how much computing time is needed to execute the set of instructions. If the client computer is operating on battery power, the client computer determines if there is enough battery life remaining to execute the set of instructions. If not, then the set of instructions are disregarded.
摘要:
A method is disclosed for securely updating system attributes of a client computer with a BIOS and includes signing a public key of a secure server with a private key of the BIOS prior to completion of manufacturing of the client computer to create an encrypted public key and embedded private key stored at the server. The method includes receiving at the server a request packet transmitted from the client computer requesting system attribute modification, encrypting the request packet to create an encrypted packet, and transmitting a return packet to client computer comprising the encrypted packet, the server's public key, and server instructions. The client computer decrypts the request packet using the server's public key and compares it to the original request packet, and if identical, executes the server instructions to modify the client computer's boot block to update client computer's system attributes.
摘要:
An electronic device receives a stop position tag that indicates a stop position within first electronic content which is a first sensory type. The electronic device identifies a start position within second electronic content using the stop position tag. The second electronic content is a second sensory type that is different than the first sensory type. In turn, the electronic device executes the second electronic content at the identified start position. In one embodiment, the first sensory type is an auditory sensory type and the second sensory type is an image sensory type.
摘要:
An apparatus and method are disclosed for dynamically zoning a touch screen environment. The apparatus includes an identification module detecting a number of users around a perimeter of a display, a zoning module generating, via a processor, a plurality of user zones in response to the number of users detected, and a positioning module orienting a gesture zone, within each of the plurality of user zones, in relation to a corresponding user. The method includes detecting a number of users around a perimeter of a display, generating, via a processor, a plurality of user zones in response to the number of users detected, and orienting a gesture zone, within each of the plurality of user zones, in relation to a corresponding user.
摘要:
An apparatus, system, and method are disclosed for computer system power management. A control module 602 is activated on a computer 200 in response to an event and enters 818 a standby state if the computer 200 is not already 814 in the standby state. A policy module 604 detects 904 a power source of a predetermined type connected to the computer 200 and dictates 908 one or more processors 302 of higher power consumption for a more abundant type of power source such as an AC adapter 314, or one or more processors 304 of lower power consumption for a less abundant type of power source such as a battery 318. A configuration module 606, activated by the control module 602, switches 1004 the computer 200 to one or more processors 302 and 304 of a predetermined power consumption as dictated and exits 1016 the standby state.
