For example, one embodiment of a system comprises: a client device; an authenticator of the client device to securely store authentication data including one or more verifiable claims received from one or more claim providers, each verifiable claim having attributes associated therewith; and claim/attribute processing logic to generate a first verifiable claim binding for a first verifiable claim issued by the claim provider; wherein the authenticator is to transmit a first signature assertion to a first relying party to authenticate with the first relying party, the first signature assertion including an attribute extension containing data associated with the first verifiable claim binding.

Abstract: A system, apparatus, method, and machine-readable medium are described for fast authentication. For example, one embodiment of a system comprises: a local challenge generator of a client apparatus to generate a challenge on a client device using a derivation function; an authentication engine of the client apparatus to generate a challenge response as defined by a specified challenge-response protocol; the authentication engine to transmit the challenge response to a server, and the server to validate the challenge response, at least in part, by determining whether the challenge was generated within a specified time window.

Abstract: A system, apparatus, method, and machine-readable medium are described for defending against malicious code injection. For example, one embodiment of an apparatus comprises: a processor to execute an application to access a web page on the Internet in response to user input, the web page having one or more resource descriptors and/or code descriptors associated therewith; an authenticator engine to validate the web page based, at least in part, on the resource descriptors and/or code descriptors, by connecting to a trusted entity; and wherein the trusted entity is configured to generate a signature on a cryptographic assertion that includes one or more resource descriptor objects associated with the one or more resource descriptors and/or one or more code descriptor objects associated with the one or more code descriptors.

Abstract: A system, apparatus, method, and machine readable medium are described for implementing a composite authenticator. For example, an apparatus in accordance with one embodiment comprises: an authenticator for authenticating a user of the apparatus with a relying party, the authenticator comprising a plurality of authentication components; and component authentication logic to attest to the model and/or integrity of at least one authentication component to one or more of the other authentication components prior to allowing the authentication components to form the authenticator.

Abstract: A system, apparatus, method, and machine readable medium are described for performing eye tracking during authentication. For example, one embodiment of a method comprises: receiving a request to authenticate a user; presenting one or more screen layouts to the user; capturing a sequence of images which include the user's eyes as the one or more screen layouts are displayed; and (a) performing eye movement detection across the sequence of images to identify a correlation between motion of the user's eyes as the one or more screen layouts are presented and an expected motion of the user's eyes as the one or more screen layouts are presented and/or (b) measuring the eye's pupil size to identify a correlation between the effective light intensity of the screen and its effect on the user's eye pupil size; capturing audio of the user's voice; and performing voice recognition techniques to determine a correlation between the captured audio of the user's voice and one or more voice prints.

Abstract: A system, apparatus, method, and machine-readable medium are described for endorsing authenticators. For example, one embodiment of an apparatus comprises: a first instance of an authenticator associated with a first app to allow a user of the first app to authenticate with a first relying party; a secure key store accessible by the first instance of the authenticator to securely store authentication data related to the first app; and a synchronization processor to share at least a portion of the authentication data with a second instance of the authenticator associated with a second app to be executed on the apparatus.

Abstract: A system, apparatus, method, and machine readable medium are described for adaptive authentication. For example, one embodiment of an apparatus comprises: an adaptive authentication module to receive a client request to perform a transaction which requires authentication; a risk engine to analyze first data related to a client to determine a risk value associated with the client; an assurance level gain analysis module to determine an assurance level required for allowing the client to complete the transaction and to determine an assurance level gain required to arrive at the assurance level based on the risk value; the adaptive authentication module to select one or more authentication techniques based at least in part on the indication of the assurance level gain.
