The background task is always active and functions to respond to an incoming call even if the user is in a graphical user interface window that requires some input from the user (e.g. the graphical user interface is blocked).

Abstract: A method and system utilizing both (x, y) coordinate (“spatial”) stroke data and associated pressure information for improved handwriting recognition. The method and system can also be applied to all types of handwriting-based data entry applications and also to user authentication. The digitizer pad used in the computer system gives both spatial information and associated pressure data when a stroke is being drawn thereon, e.g., by a stylus. Pressure information can be used to differentiate between different character sets, e.g., upper case and lower case characters for certain alphabetic characters. The spatial stroke data then identifies the particular character. The pressure information can also be used to adjust any display attribute, such as character font size, font selection, color, italic, bold, underline, shadow, language, etc. The associated pressure information can also be used for recognizing a signature. In this case, a user is allowed to sign a name on the digitizer pad.

Abstract: A method and system for implementing URL scheme proxies. Embodiments of the invention allow URL schemes that are not natively supported by a computer to be supported via proxy, e.g., using a URL scheme that is native to the computer to forward the non-native transport. More specifically, embodiments of the invention allow a first computer system to support a first URL scheme by encapsulating its transport information into another URL scheme that is natively supported by the first computer. The encapsulated information is then forwarded to a second computer system or server which can provide support for the first URL scheme transport. For instance, if the first computer supports http but does not support ftp, then an ftp transport can be encapsulated inside an http transport and then forwarded to an ftp server which can then extract and process the ftp transport. The ftp response can be handled in an analogous fashion. The invention increases the native URL scheme capabilities of a computer system by proxy.

Abstract: A method and system for a device and carrier independent geographic location protocol. Specifically, the present invention provides location information of a mobile device to third parties in a communication network through a protocol that is device and network carrier independent. Position information of any first format is sent to a proxy server. An identifier that identifies the type and format of the position information is also sent. The proxy server then locates and accesses an executable plug-in module associated with the identifier to convert the position information of the first format into one of a plurality of standard location formats. The executable plug-in module converts the position information into a second standard format as required by the third party. After the position information is converted to the second format, the proxy server sends the position information to the third party.

Abstract: A computer system that attempts to establish an alternative network link upon failing to establish a requested network link is described. The computer system may encounter conditions where access to numerous networks, in particular wireless networks, is not available. Rather than only providing an error message to the user upon a failed attempt to establish the requested network link, the computer system determines whether the user has designated an alternative network link in case the requested network link cannot be established, whereas the alternative network link is selected from the plurality of network links that the computer system is configured to support. If an alternative network link has been designated, the computer system attempts to establish the alternative network link. Hence, the user experience is made smooth and uneventful when the requested network link cannot be established.

Abstract: A method and apparatus for authenticating and authorizing online transactions. An authentication cookie is transmitted to a client system. The authentication cookie includes a user encryption key and an encrypted buffer that contains user identification data and a profile code. Subsequent requests for the particular service use the authentication cookie to generate a query that includes the encrypted buffer and user identification data entered by the user. Portions of the query are encrypted using the user encryption key. Queries received at each authentication and authorization server are authenticated by reconstructing the user encryption key using information transmitted in the clear and decrypting the query using both the reconstructed user encryption key and the secret key. The user identification data entered by the user is then compared with the user identification data in the encrypted buffer for further authentication. The profile code is analyzed for determining authorization.
