Abstract

A portable device may be configured to transmit a digital signature of a user to an Internet terminal for the user to complete a transaction requiring a signature. The portable device may be a remote control, a personal digital assistance (“PDA”), an electronic pen, and the like. The portable device may include an wireless transceiver to provide transmit capability of the digital signature to the Internet terminal. The portable device may also provide receive capability to receive the digital signature of the user from another signature source and a memory to provide storage capability of the digital signature. Alternatively, the portable device may include an encryptor module to generate a digital signature based on a characteristic of the user and/or the portable device. The portable device may yet further include a keypad to provide an interface for the user to complete transactions requiring the digital signature provided by the portable device. Accordingly, by providing a user with a portable digital signature, the user may become mobile and have the capability to complete electronic transactions at any compatible Internet terminal.

Claims

1. A method for conducting an electronic transaction, said method comprising:

storing a digital signature of a user in a memory of a portable device;

performing said electronic transaction; and

transmitting said digital signature of said user from said portable device to complete said electronic transaction.

2. The method for conducting an electronic transaction according to claim 1, further comprising:

presenting said electronic transaction on an Internet terminal;

receiving said digital signature by said internet terminal; and

presenting a verification of conclusion of said electronic transaction.

3. The method for conducting an electronic transaction according to claim 2, wherein said digital signature of said user is transmitted utilizing wireless protocols.

4. The method for conducting an electronic transaction according to claim 2, wherein said Internet terminal comprises a high definition television (“

HDTV”

) set.

5. The method for conducting an electronic transaction according to claim 4 wherein said portable device comprises a remote.

6. The method for conducting an electronic transaction according to claim 2 wherein said portable device comprises an electronic pen.

7. A device for transmitting a digital signature, said device comprising:

a memory;

a keypad configured to provide a user interface;

a wireless transceiver; and

a controller configured to transmit a digital signature stored in said memory through said wireless transceiver in response to a first input from said keypad.

8. The device for transmitting a digital signature according to claim 7, wherein said controller is further configured to receive said digital signature from a second device adapted to generate said digital signature in response to a second input from said keypad.

9. The device for transmitting a digital signature according to claim 8, wherein said controller is adapted to transmit commands to a high definition television (HDTV) set.

11. The device for transmitting a digital signature according to claim 9, wherein said controller is adapted to transmit commands to a high definition television (HDTV) set.

10. An apparatus for generating a digital signature, said apparatus comprising:

an encryptor module;

a keypad;

a wireless transceiver, and

a controller configured to transmit a digital signature through said wireless transceiver in response to a first input from said keypad, said digital signature generated by said encryptor module.
