Abstract: A device including circuitry configured to receive a security profile corresponding to one or more of a user and an application to which an output of a secure text generation process will be applied, wherein the security profile includes a private key. The circuitry may receive a sequence of characters input from a text input device in communication with the circuitry. The circuitry may generate, for each character input in the sequence of characters, one or more random characters, wherein the one or more random characters are generated based on an algorithm having the character text input and the private key as inputs, and wherein the algorithm includes a mathematical function corresponding to the private key. The secure text generation process is iteratively performed on a single character, of the sequence of characters received from the text input device, without storing preceding received characters included in the sequence of characters.

Abstract: An apparatus including circuitry configured to receive a plurality of images and extract at least one iris image from each of the plurality of images. The circuitry is configured to receive a claimed identity iris image corresponding to an identity to be authenticated, normalize the iris images and the claimed identity iris image, and filter the normalized extracted iris images to select a subset of the normalized extracted iris images based on a similarity measurement relative to the normalized claimed identity iris image. The circuitry is configured to divide the normalized claimed identity iris image and each image of the subset of images into a plurality of sub-images, filter the sub-images to select the sub-image having a closest similarity measurement relative to a sub-image of the normalized claimed identity image in a corresponding sub-image position to the selected sub-image, and generate a composite iris image by fusing the selected sub-images.
