Negotiated wireless peripheral security systems

For use in a mobile unit that communicates with a negotiated wireless peripheral (NWP) device, a method comprising:

• establishing via a wireless local area network air interface a position-dependent ecommerce session with the NWP device and contracting for the use of at least one peripheral that supports enhanced user interface capabilities;
• redirecting at least one input-output stream to the at least one peripheral supplied by the NWP device in order to allow an application program to deliver content using a non-area-constrained user interface;
• establishing via a wireless wide area network connection an end-to-end secure client-server session between the mobile unit and a remote server that provides an application service;
• and
• supplying a client-side and non-area constrained user interface to the user to allow the user to interact with the remote server using the at least one augmented peripheral.

For use in a mobile unit that uses a wireless wide area network (wWAN) air interface to communicate via a wide area network (WAN) with one or more remote servers and a wireless local area network (wLAN) air interface to contract with a negotiated wireless peripheral (NWP) device, a method comprising:

• establishing via the wLAN air interface a position-dependent ecommerce session with the NWP device;
• redirecting at least one input-output stream to at least one peripheral supplied by the NWP device in order to allow an application program to deliver content to a non-area-constrained user interface, whereby the at least one peripheral includes an input device;
• establishing or redirecting a client-server packet stream via the wLAN and through the WAN to support an end-to-end secure session between the mobile unit and a selected remote server, whereby the mobile unit performs cipher processing using at least one security parameter from an end-to-end security association between the mobile unit and the selected remote server;
• storing in the mobile unit at least one secure information record for secure transmission to with the remote server;
• and
• securely passing the secure information record to the remote server without the need to type in the information stored in the secure information record into the input device supplied by the negotiated wireless peripheral.

• and
• projecting a non-area constrained user interface image on a projection-display surface in order to supply a display area in support of a non-area constrained.

A mobile unit comprising:

• a set of peripherals that in total support an area-constrained user interface and a non-area constrained user interface;
• and
• a display projector that projects a non-area constrained user interface display onto a display surface;
• whereby the set of peripherals includes a pointing and selection device capable of controlling a cursor image on the projected non-area constrained user interface and making selections based on interactive portions of the projected non-area constrained user interface.
