Abstract: Disclosed is a powerless electronic signature apparatus based on a fingerprint recognition comprises: an external communication part having an electrical connection terminal for receiving an external power and a communicative connection terminal for providing an electronic signature service means with the electronic signature creating key; a fingerprint scanner for scanning a fingerprint of a signer to create a recognition finger code; a fingerprint recognizing part for comparing the created recognition fingerprint code with a reference fingerprint code and allowing for an access to the electronic signature creating key; and an electronic signature control part for controlling the fingerprint scanner to create a recognition fingerprint code when a power is applied from the external communication part and controlling the nonvolatile memory to provide the electronic signature service means with the electronic signature creating key through the external communication part.
