An accessory device receives authentication information from a host computing device connected thereto and determines whether the authentication information is valid. If the authentication information is valid, the accessory device applies a first access policy that specifies whether the accessory device can provide the host computing device with access to none, some, or all of various computing resources of the accessory device. If the authentication information is not valid, the accessory device applies a second access policy that is different than the first access policy. The accessory device can also be provisioned with access policies by a host computing device if the host computing device successfully authenticates with the accessory device. In either case, authenticating the host computing device may include verifying a digital signature of a certificate provided by the host computing device using a public key of a certificate authority that has been provisioned to the accessory device.

Secure access to accessory device resources

Architecture for enabling continuous operation of a control command issued by a control input (e.g., a control key on a computer keyboard or game controller). For example, for a user of a software application (e.g., a gaming application), an activation modifier is used for enabling continuous operation of the control command. The activation modifier can be a lock key or other type of input used in combination with the control key. During continuous operation of the control command, one or more alternate control inputs (e.g., from alternate control keys) are enabled to concurrently issue alternate control commands to the software application.

Continuous automatic key control

Accessory device authentication techniques are described. In one or more embodiments, connection of an accessory device to a host computing device is detected. Responsive to the detection, an authentication sequence may occur to verify an identity and/or capabilities of the accessory device. Upon successful authentication of the accessory device, the host device may authorize the accessory device for power exchange interactions with the host device. The host device may then draw supplemental power from a power source associated with the authorized accessory device, such as a battery or power adapter. The host device may also enable the accessory device to obtain and use power supplied by the host device in some scenarios. Power exchange between a host device and an authorized accessory may be managed in accordance with capabilities of the accessory device that are identified during authentication.

Accessory device authentication

Computer-readable media, computerized methods, and computer systems for alerting a user that an operating system has entered a secure mode is provided. Initially, inputs are received at an operating system residing in a default mode. Typically, the default mode allows applications running on the operating system to access the inputs. If the inputs are identified as a call to perform a protected operation, the operating system is transitioned from the default mode to the secure mode. Typically, the secure mode restricts the applications from intercepting the inputs. The transition to the secure mode is automatically communicated to the user via an indicator device. Generally, automatic communication includes providing a message from the operating system to the indicator device over a secure pathway that triggers the indicator device to generate a user-perceivable output. Accordingly, the operating system exerts exclusive control over the operation of the indicator device.

A peripheral device is connectable to a computer having one of a first interface and a second interface. The first interface communicates with the peripheral device over a differential data connection having a first data conductor and a second data conductor. The second interface communicates with the peripheral device over a clock conductor and a single ended data connection which includes a data conductor. The peripheral device has first and second communication conductors. The peripheral device includes an interface detection component coupled to the first and second communication conductors and configured to detect which of the first and second interfaces the peripheral device is connected to.

Method and apparatus for detecting the type of interface to which a peripheral device is connected

Keyboard apparatus and methods for processing keyboard depressions are disclosed. One disclosed keyboard apparatus includes a keyboard having a plurality of keys configured to be depressed in a concurrent depression state, and a plurality of key switch matrices. Each key switch of the plurality of key switch matrices may be configured to be actuated by a corresponding key of the keyboard. The keyboard apparatus may further include a keyboard controller configured to determine whether a sensed key depression in the concurrent depression state is a ghost key depression, based on sensed key switch states of respective key switches in each of the plurality of key switch matrices which correspond to the sensed key depression.

A security-enhanced login technique that provides a convenient and easy-to-use two factor technique to enhance the security of passwords without requiring any changes on the server side of a client-server network. The technique employs a convenient and easy-to-use two-factor technique to generate strong passwords for Web and other applications. In this technique, a convenient or personal device such as a mouse is used as the other factor besides a user password. A secret stored in the mouse or other personal device is hashed together with the password entered by a user and the server ID, to generate a strong, server-specific password which is used to authenticate the user to the server. This password enhancement operation is carried out inside the personal device.

A peripheral device, with first and second communication conductors, is connectable to a computer having one of a first interface and a second interface. The first interface communicates with the peripheral device over a differential data connection having a first data conductor and a second data conductor. The second interface communicates with the peripheral device over a clock conductor and a single ended data connection which includes a data conductor. The peripheral device includes an interface detection component coupled to the first and second communication conductors to detect which of the first and second interfaces the peripheral device is connected to.

A peripheral device, connected to a computer, has either a first or second interface. The first interface communicates over a differential data connection and the second interface communicates over a clock conductor and a single ended data connection. The peripheral device has first and second communication conductors that are either connected to the differential data connection when the computer includes the first interface or to the single ended data connection and the clock conductor when the computer includes the second interface. The peripheral device has an interface detection component that detects which of the first and second interfaces the peripheral device is connected to. The peripheral device also has a controller that communicates according to a protocol corresponding to the detected interface.

A device for detecting the position of a human finger or other object on a touch-sensitive scrolling pad. Dual independent oscillators may be used to generate two pulse trains at frequencies dependent upon the capacitance of two conductors resulting from the position of the finger on the conductors. The pulses from each oscillator may be counted over a time interval. A ratio-metric measurement may be taken by calculating the ratio of the two counts, and a sum may also be calculated. The ratio of the two counts relates to finger position on the device, and their sum relates to finger pressure upon the device.

The peripheral device also includes a controller component configured to communicate between the peripheral device according to a protocol corresponding to the detected interface.

A system and method for providing a continuous input mode is disclosed. In the continuous input mode, a combination of a vector signal and a command signal is received from an input device. Upon receipt of a vector signal and a command signal, an image is moved on a display screen, for example. The image continues to move until the command signal is terminated. If a new vector signal is received prior to termination of the command signal, then the direction of image movement may be changed and will occur until termination of the command signal. Additional aspects of the present invention relate to input devices and computer-readable media with computer executable instructions utilized in switching between the input modes.
