摘要： A computing device remote control system includes a remote-control device, a remote-control adapter that is communicatively coupled to the remote-control device, and a computing device including a computing device Universal Serial Bus (USB) connector that is connected to the remote-control adapter. A function controller in the computing device is coupled to the computing device USB connector and operates to receive a remote-control message from the remote-control device via the computing device USB connector and the remote-control adapter and, in response, change a control function state stored in the function controller, and generate and transmit an alert. A system controller in the computing device is coupled to the function controller and operates to receive the alert from the function controller and, in response, access the function controller to identify the control function state stored in the function controller, and perform at least one control operation based on the control function state.

摘要： A pre-boot authentication (PBA) credential sharing system includes a secure subsystem including an off-host processing system and a secure storage. A credential management application is coupled to the off-host processing system. A data protection engine is coupled to the off-host processing system and a PBA database. The data protection engine receives a notification from the off-host processor of the enrollment of an authentication credential in the secure storage by the credential management application, and provides PBA object information for association with the authentication credential to create a PBA object that is stored in the secure storage. Subsequently, while in a pre-boot environment, the data protection engine requests the PBA object from the secure storage, retrieves storage authentication information from the PBA database using the PBA object, and performs a pre-boot authentication process using the storage authentication information.

摘要： An information handling system includes a display device and a processor. The display device outputs pixels associated with a text font. The processor converts red, green, blue (RGB) pixels to image perspective transformation (IPT) pixels. The processor further sharpens one or more of the IPT pixels that do not have color. The sharpening of the one or more of the IPT pixels identifies edges of the text font and defines widths of the text font. The processor corrects edge overshoot and edge undershoot created by a digital filter. The edge overshoot and the edge undershoot are corrected for each IPT pixel associated with the text edges. The processor also reduces noise enhancement in the sharpened IPT pixels, retains grey text portions of each of the sharpened IPT pixels, and converts the IPT pixels to new RGB pixels. The processor outputs the new RGB pixels to the display device.

摘要： An off-host authentication system includes an authentication information handling system (IHS) that is coupled to a network. The off-host authentication system also includes a host processing system. An off-host processing system in the off-host authentication system is coupled to the host processing system and is coupled to the authentication IHS through the network. The off-host processing system provides an encrypted primary authentication item to the authentication IHS through the network. The off-host processing system then receives an encrypted secondary authentication token from the authentication IHS through the network. The off-host processing system then decrypts the encrypted secondary authentication token to produce a decrypted secondary authentication token and uses the decrypted secondary authentication token to retrieve a tertiary authentication token. The off-host processing system then provides the tertiary authentication token to the host processing system for use in logging a user into a user IHS that includes the host processing system.

摘要： An encryption key management system includes an encryption IHS that is coupled to a network. The encryption key management system also includes a host processing system. An off-host processing system in the encryption key management system is coupled to the host processing system and is coupled to the encryption IHS through the network. The off-host processing system provides an encryption key request to the encryption IHS through the network, receives an encryption key from the encryption IHS through the network and stores the encryption key, provides the encryption key to the host processing system in response to authenticating a user, and revokes the encryption key in response to a revocation instruction received from the encryption IHS through the network. The providing the request, and the receiving, providing, and revoking the encryption key may be performed by the off-host processing system while the host-processing system is not in an operating mode.

摘要： An off-host authentication system includes a network. An off-host processing system is coupled to the network and sends an encrypted authentication item through the network in response to validating a user. An authentication information handling system (IHS) is coupled to the network and receives the encrypted authentication item from the off-host processing system through the network, decrypts the encrypted authentication item to produce a decrypted authentication item, validates the decrypted authentication item, and sends an approval message through the network. A directory system is coupled to the network and receives the approval message through the network and, in response, sends a user approval through the network. A host processing system, which is located in a user IHS that includes the off-host processing system and which is coupled to the network, logs a user into the user IHS in response to receiving the user approval through the network.
