摘要:
A method of providing a password to a handheld electronic device having a reduced keyboard and a non-predictive keystroke interpretation system, wherein the reduced keyboard is of a particular keyboard type and the non-predictive keystroke interpretation system is of a particular system type. The method includes receiving a first character string in an electronic device, such as, without limitation, a PC, that is separate from the handheld electronic device, generating one or more second character strings in the electronic device based on the particular keyboard type, the first character string, and, possibly, the particular system type, and transmitting the one or more second character strings from the electronic device to the handheld electronic device as the password.
摘要:
A system and method for controlling data communications between a server and a client device, such as a mobile device. Embodiments relate generally to a technique where stop data is provided to the client device. This stop data can be transmitted (e.g. by the client device) to the server. When processed by the server, the stop data indicates to the server that at least some of the encrypted data received by the client device from the server was not decrypted using the second key (e.g. as may be the case when the second key has been deleted). Upon receiving the stop data, the server may, for example, withhold the transmission of data encrypted with the first key to the client device until the second key is restored on the client device. In one embodiment, the stop data is provided to the client device in an encoded (e.g. encrypted) form.

A system includes a wireless-enabled smart card reader able to be connected concurrently to at least two devices and a mobile device able to be connected wirelessly to the smart card reader and to control connections of the smart card reader.
摘要:
A system and method for facilitating communication of packets between one or more applications residing on a first computing device and at least one second computing device. The system comprises a connection manager adapted to receive packets from the at least one second computing device, and a packet cache for storing packets received by the connection manager. The connection manager, upon receiving a packet from a second computing device, transmits the packet to the packet cache for storage and notifies each of the applications of receipt of the packet. Subsequently, the packet is retrievable from the packet cache by a notified application, and verification that the packet is intended for communication to the notified application is made.
摘要:
A method of authenticating a user of a computing device is proposed, together with computing device on which the method is implemented. In the method, an authentication video is displayed on a display. In response to receiving an input at a point in time in the video that matches a pre-selected time reference point, positive authentication is indicated.
摘要:
In one embodiment, a method is provided for managing secure registration of a mobile communications device, the method comprising registering, at a network node, the mobile communications device using a first registration process, the first registration process requiring an authentication key associated with the mobile communications device; processing a request from the mobile communications device, the request including an indication that the mobile communications device is changing to a second registration process; and clearing the authentication key associated with the mobile communications device upon expiration of a time window.
摘要:
After a predetermined limit for decryption attempts has been exceeded by a user attempting to decrypt an encrypted electronic message or attempting to decrypt a encrypted electronic certificate associated with an electronic message, access to the electronic message may be restricted.
摘要:
A communication device includes a display screen upon which information is displayed. A microprocessor configured to execute at least one notification program is provided that displays a notification descriptive of an access control request on the display screen. The at least one notification program is programmed to receive data indicative of an access control request and to receive data descriptive of the access control request. Additionally, the at least one notification program is further programmed to display a notification indicative of the access control request and comprising an explanation of the access control request based on the received descriptive data.
摘要:
An adaptive endpointer system and method are used in speech recognition applications, such as telephone-based Internet browsers, to determine barge-in events during the processing of speech. The endpointer system includes a signal energy level estimator for estimating signal levels in speech data; a noise energy level estimator for estimating noise levels in the speech data; and a barge-in detector for increasing a threshold used in comparing the signal levels and the noise levels to detect the barge-in event in the speech data corresponding to a speech prompt during speech recognition.
摘要:
A signal conditioning system for improving the analog signal-to-noise ratio. The system first filters (to reduce the extrinsic noise outside the bandpass), then squares (to reduce the intrinsic noise inside the bandpass), finally transforms the improved analog signal into a digital-like signal (using a threshold circuit) to interface with associated control logic in an ink jet droplet apparatus.
