A method for transmitting verified notification messages from a service provider to a PID (personal information device) user. The method includes the step of registering a plurality of users and providing each of the users with respective public and private encryption keys. A message is then received from a first user of the plurality of users. The received message is signed with the first user's private encryption key. A signature of the message is verified by using the first user's public encryption key. The authority of the first user to transmit notification messages is then verified. The message is then resigned with the second user's private encryption key and transmitted to at least a second user of the plurality of users, wherein the second user verifies the signature by using the second user's public encryption key. Thus, the encryption provides a reliable means for differentiating between regular notifications and emergency notifications and is secure for authenticating and authorizing the messages sent from the service provider. A priority can be assigned to the message in accordance with a priority indicated by the first user. The message can be transmitted with the assigned priority to the second user, thereby allowing the second user to process the message in accordance with the assigned priority. The encryption keys can be stored in a database of the service provider.

A filtering method and apparatus for an electronic device. The operating system's program registry is copied and then modified to direct all application data to a filter program such as a virus scanning filter program. If the filter program determines that the object is virus free, the copy of the program registry (filter registry) is queried by the filter program to determine the application program associated with the data object. The data object is then forwarded to the appropriate application program.

A method of processing data using a portable electronic device includes transcoding, using a processor of the portable electronic device, a first webpage to generate a second web page. The second web page is displayed using a display device of the portable electronic device.

Hand-held browser transcoding

A method and apparatus that provides adaptation in the content delivered to a palmtop computer. Connections between a palmtop computer and the Internet can vary from low speed dial-up to very high speed. Also, a palmtop computer's display, memory and processing power can vary considerably. Communication with the Internet is generally through a proxy server that can deduce these considerations from the palmtop computer's serial number and/or other information specified by user. The proxy server can then adapt the content based upon these considerations (e.g. only send two bit gray scale images to non-color palmtop computer, only send first frame of animated gif to low processing power palmtop computer, etc.).

Adaptive content delivery

A hand-held computer device with integral web page transcoding. A processor, forming a part of the handheld computer has a display coupled to the processor forming a part of the handheld computer, with the display having limited resolution of M&#xd7;N pixels. A browser program running on the processor facilitates retrieving and viewing of a web page having size greater than M&#xd7;N on the display. This is accomplished in a browser having an associated browser plug-in that transcodes the web page to a format adapted to the display. The transcoding is carried out by, among other things, generating a menu of frames from the web page to permit a user to select a desired frame for display by selecting frame titles as menu selections and compressing an image to a size suitable for display on the M&#xd7;N resolution display.

A Trojan horse method and apparatus to permit email access to secure enterprise resources within an enterprise's firewall. An email message is used to permit a user to gain access to computer resources such as databases maintained within a secure enterprise's firewall. An email message generated from a palmtop computer or any other computer capable of sending and receiving email messages is used to pass through the firewall as a conventional email message would. The email message is received at a designated computer that recognizes reserved command words as a part of the email message, preferably as a part of the subject line thereof. Upon recognizing the reserved command word, the email message is parsed to determine key components of a command that can be executed on a desired enterprise computer resource. An appropriate command (e.g., an SQL query) is then created for execution on the enterprise computer resource (e.g., a database). A response or acknowledgement is then returned to the sender as an email message.

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. If the query is authenticated and authorized, the authentication and authorization server forwards the request to a server that provides the desired service.

A secure simplified transaction processing method and apparatus for a palmtop computer. Sensitive personal information is stored in a secure personal information database. A site map database contains information which maps the fields of the personal information database to frames of a Web page. On request of a palmtop computer, a robot program correlates the personal information fields with the frames of the Web page and sends the personal information back to the palmtop computer. The palmtop computer uses this information to automatically populate the frames of a Web clipping representing a Web page. This has the advantage that the user does not have to manually fill in the frames of the web clipping while providing security for sensitive information.

System using email message to transmit a command to remotely control a computer resource

A method of routing telephone calls, emails and faxes using a palmtop computer. Using a date book forming a part of a personal information manager application of a palmtop computer, the user enters an appointment into the date book. Such an appointment has a starting and an ending time. The user then selects (either at the time of entry of the appointment or after receipt of an alarm reminder of the appointment) a destination telephone number for routing of telephone calls between the starting time and the ending time. This selection can be in the form of a menu selection of a predetermined profile for routing telephone calls. The palmtop computer then sends a representation of the destination telephone number, the starting time and the ending time to a telephone call server (and/or email server and/or fax server), so that the telephone call server routes telephone calls to the destination telephone number between the starting time and the ending time.
