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 a modified base image is overlaid with a modified overlay image on a display. The modified overlay image comprises a plurality of numbers. At least one of the modified base image and modified overlay image is moved by the user. Positive authentication is indicated in response to the base image reference point on the modified base image being aligned, in sequence, with two or more numbers from the overlay image that equal a pre-selected algebraic result when one or more algebraic operator is apply to the numbers.

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 a modified base image is overlaid with a modified overlay image on a display and with each execution of the method, at least one of a position of a pre-selected base image reference point on the modified base image and a position of a pre-selected overlay image reference point on the modified overlay image is varied. Positive authentication is indicated in response to an input resulting in the base image reference point on the modified base image being aligned with the overlay image reference point on the modified overlay image.

A system and method are provided for pre-processing encrypted and/or signed messages at a host system before the message is transmitted to a wireless mobile communication device. The message is received at the host system from a message sender. There is a determination as to whether any of the message receivers has a corresponding wireless mobile communication device. For each message receiver that has a corresponding wireless mobile communication device, the message is processed so as to modify the message with respect to one or more encryption and/or authentication aspects. The processed message is transmitted to a wireless mobile communication device that corresponds to the first message receiver. The system and method may include post-processing messages sent from a wireless mobile communications device to a host system. Authentication and/or encryption message processing is performed upon the message. The processed message may then be sent through the host system to one or more receivers.

One embodiment of a method of authenticating data comprises: receiving, at a device, data in a plurality of indexed packets transmitted by a data server, the data of the indexed packets being at least a portion of a larger data stream; receiving, at the device, from a data authentication server connected to the device by a network, a server-computed authentication value based on a subset of the data transmitted by the data server, the data authentication server having access to the data that was transmitted from the data server to the device; and comparing a device-computed authentication value based on a subset of the received data, corresponding to the subset of the data transmitted by the data server, with the server-computed authentication value in order to determine whether the subset of the data received at the device is authentic.

A system and method for processing attachments to messages sent to a mobile device is described herein. Embodiments described herein apply to encrypted messages comprising multiple message parts, in which different encryption keys (e.g. session keys) have been used to encrypt the different message parts. In at least one example embodiment, the encrypted session keys for every message content part comprising an attachment is received at the mobile device. In one embodiment, all of the encrypted session keys are stored together in a main message header. The mobile device may then decrypt the encrypted session key associated with a user requested attachment, and transmits the decrypted session key to one or more remote servers in an attachment request for use in decrypting the requested attachment. Data associated with the requested attachment, in decrypted form, is returned to the mobile device.

摘要:
A key agreement method is carried out by a first system in conjunction with a second system over a bidirectional communication path, including generating a first key pair having a first public key and a first private key, sending the first public key to the second system, receiving a second public key generated by the second system, and calculating a master key based upon the first private key, the second public key, a long-term private key, and a long-term public key. The long-term private key was generated by the first system during a previous key-agreement method as part of a long-term key pair. The long-term public key was generated by the second system and received during the previous key-agreement method. The previous key-agreement method required a secret to be known to the first system and the second system, thus conferring authentication based on the secret to the long-term public key.

Methods and systems for mitigating the effects of a malicious software application are disclosed. A dedicated module on the computing device receives from a malicious software detector a message indicating whether the application is malicious or has a malicious component. The dedicated module obtains a set of permissions to be granted to the application, and instructs software on the computing device that controls the permissions of the application to grant the set of permissions.

A displayed string of emails is effectively compressed for improved readability by deleting some or all headers and/or by skipping the cursor from one message body to another in response to “hot” key actuation (s) by a user.
摘要:
A method of recognizing speech input selectively creates and maintains grammar representations of the speech input in essentially real time. Speech input frames are received by a speech recognition system. Grammar representations are created for each speech frame and a probability score is derived for the representations indicating the probability of the accuracy of the representations to the speech input. Representations having a probability score below a predetermined threshold are not maintained. Those grammar representations having probability scores above the predetermined threshold are maintained. As more speech frames are received by the system, additional grammar representations are created and the probability scores are updated. When the entire speech input has been received, the chain of grammar representations having the highest probability score is identified as the speech input.
