Systems and methods are provided for facilitating access to an electronic device. Password information is stored on the electronic device, and on a portable authenticator. When a user attempts to access the electronic device, the user is prompted to enter a password at the electronic device. The portable authenticator determines the validity of the entered password. The electronic device receives the results of the validity determination from the portable authenticator, and provides access to the electronic device based on the received validity determination.

A method for training a server for content delivery based on communication of state information from a mobile device browser, the method comprising providing a control channel between the server and mobile device browser, transmitting over the control channel a plurality of request messages from the mobile device browser to the server for Web pages, each of the messages indicating browsing-related state data, and implementing heuristic algorithms within the server to detect and learn patterns of the request messages, pre-fetching at least hypertext content of Web pages that the server has learned will likely be requested, and embedding the hypertext content in response codes within response messages over the control channel from the server to the mobile device browser.

A system and method of processing a markup language based electronic mail includes identifying in a head section of markup language code any style rules for rendering the markup language based e-mail and sorting the style rules in order of reference in the markup language code, interleaving the style rules for placement in a body section of one or more blocks of markup language code corresponding to one or more sections of the markup language based e-mail, wherein interleaving is based on predetermined rules, and storing the one or more blocks of markup language code including the interleaved style rules as separately downloadable blocks of data corresponding to sections of the markup language based e-mail. The method may also include receiving, at a mobile communication device, a block of markup language code for rendering a section of the markup language based e-mail on a display, identifying in the block of markup language code any style rules interleaved therein for rendering the section of the markup language based e-mail on the display, processing the interleaved style rules identified in the block of markup language code, and rendering the section of the markup language based e-mail on the display based on the processed style rules.

A portable electronic device includes a rendering circuit to visualize large format data files on a narrow display. The large format data files are rendered using either a desktop display mode or a mobile display mode. The desktop display mode renders the data file using data file-specified dimensions and resolutions. The data file is viewable in its entirety by automatic scrolling achieved by moving a cursor near the edge of the display. Data file elements may be edited while in desktop display mode. The mobile display mode renders the elements of the data file as a list with minimal regard for spatial orientation. Navigation in mobile display mode is field-to-field.
摘要:
A method for communicating state information between a server and a mobile device browser with version handling includes: providing a control channel between the server and mobile device browser; transmitting at least one message from the mobile device browser to the server over the control channel indicative of browsing-related state data, wherein the at least one message includes an XML-encoded document and a protocol version value identifying a version of Document Type Definition (DTD) against which to validate the XML-encoded document; and regulating subsequent transmission of data from the server to the mobile device browser based on the at least one message.
摘要:
A method of handling cryptographic information in a communication comprising body elements and attachment elements to a mobile device includes the steps of determining if the communication includes an attachment element comprising cryptographic information and converting the attachment element into a body element upon determining that the communication includes an attachment element comprising cryptographic information.
摘要:
A method of securely synchronizing cache contents of a mobile browser with a server includes initiating a session between the browser and server, including transmission of browser state information regarding the cache contents and an authentication key to the server; maintaining a record of data sent from the server to the browser for storage in the cache; maintaining a record of the state information regarding the cache contents transmitted from the browser to the server; and transmitting data requests from the browser to the server, in response to which the server uses the key as a seed generation function and accesses each the record of data and returns only data that does not already form part of the cache contents, and wherein the data includes a result of a hash of data generated by the generation function for authentication by the browser before updating the cache contents with the data.
摘要:
A method, server and system for optimizing and delivering HyperText Markup Language (HTML)-based content such as HTML-based email messages to mobile communication devices is provided. In accordance with one embodiment, the method comprises: receiving an email message comprising an HTML portion comprising an HTML header and an HTML body; determining if the HTML header includes a reference to a Cascading Style Sheet (CSS) document comprising one or more rules; if the HTML header includes a reference to a CSS document, replacing the reference with the CSS rules of the CSS document, and sending the transformed email message to a destination mobile communication device.
摘要:
An electronic communication device includes a buffer and a controller. The buffer stores characters as they are being input by a user. The controller transmits the stored characters over a network when a pause in the input of characters exceeds a threshold time period. The controller also dynamically adjusts the threshold time period.
摘要:
A method of controlling delivery of multi-part content from an origin server to a mobile device browser via a proxy server. The method includes: transmitting an original document request from the mobile device browser to the proxy server, the document request including state information regarding the mobile device browser; retrieving data from the origin server to the proxy server responsive to the request from the mobile device browser; and creating a multi-part document including compressed versions of requested portions along with information for indicating portions already cached in the mobile device browser and information for indicating portions not yet cached in the mobile device browser.
