Abstract: A method for authentication of a user towards a multi-node party includes at least two nodes. The user contacts the nodes of the multi-node party, via a user application, and each of the nodes of the multi-node party generates a nonce and returns the nonce to the user application. The user application requests authentication from an Identity Provider, based on the nonces received from the nodes of the multi-node party and on a unique identity of the user. The Identity Provider generates a message, based on the request for authentication, and provides the message to the user application. The user application provides the message in a secret form to each of the nodes of the multi-node party. The nodes of the multi-node party verify the message by means of a multi-party verifying operation, and the user is authenticated based on the multi-party verifying operation.

Abstract: The present invention is a visual prosthesis which restores partial vision to patients blinded by outer retinal degeneration. While visual prosthesis users have achieved remarkable visual improvement to the point of reading letters and short sentences, the reading process is still fairly cumbersome. In the present invention the visual prosthesis is adapted to stimulate visual braille as a sensory substitution for reading written letters and words. The visual prosthesis system, used in the present invention, includes a 10×6 electrode array implanted epiretinally, a tiny video camera mounted on a pair of glasses, and a wearable computer that processes the video and determines the stimulation current of each electrode in real time.

Abstract: The present invention is a visual prosthesis adapted for implantation in the brain, and more particularly with an electrode array adapted for implantation in the Calcarine Sulcus of the visual cortex. The electrode array of the invention has electrodes on each side and spaced appropriately for the Calcarine Sulcus and driven by an electronic circuit within a hermetic package small enough to be implanted with a skull.
