Abstract: A biometric authentication platform (10) uses fault-tolerant distributed computing to determine if a supplied biometric sample and a sample stored in a registry are from the same person. A collection of reference samples is maintained in a distributed ledger (115) with immutable history of modifications. Results of matching are stored in a separate distributed ledger (125) providing an immutable history log. Coordinated use of both ledgers (115, 125) enable biometric authentication of registered users (140) in real time. Users (140) may interact with providers (150) and/or trusted circles of other users in order to recover user records from the user ledger (115).

Abstract: During control of a user interface via free-space motions of a hand or other suitable control object, switching between control modes can be facilitated by tracking the control object's movements relative to, and its contact with a “virtual touch plane or surface” (i.e., a plane, portion of a plane, and/or surface computationally defined in space, or corresponding to any physical surface).

Abstract: The present invention describes a device and method for touchless palmprint acquisition. The method can be applied to a terminal device (including but not limited to mobile phones, tablet computers and other portable devices) with a display screen and a front-facing camera. The camera is used to capture images of palms. The screen is used as a supplementary light source. When lighting condition in the palm area is undesirable, the screen changes its display to improve the lighting condition inside the palm, which increases the recognizability of the palmprint. The palmprint acquisition device and method described in the present invention can be directly applied to existing terminal devices without requiring any additional hardware. By adopting a variety of ways to change the display of the built-in screen of the terminal device, the lighting condition of the palm area will be improved and the recognizability of the palmprint will be increased.

Abstract: A computing platform is described to match a palm digital representation to a palm template. The platform includes logic causing presenting a viewfinder image including an image stream and/or a cue appearing to reside substantially in front of a user to guide the user to align a palm at a position within a field of view of a camera; capturing a set of images using the camera; processing the set of images to determine a set of identifying features of the palm; and comparing the set of identified features with enrolled palm prints to identify the palm.

Abstract: The invention presents a biometric authentication system comprising: a template module and a key module that are independent of each other. The template module is used to store encrypted biometric templates, the key module is used to store the decryption keys. The system may further comprise a matching module that acquires the decryption key from the key module and the encrypted template from the template module, decrypts the template using the key, then matches the template to verify the identity. In this system, the encrypted template and decryption key are stored separately both logically and physically, and are only united momentarily during matching, then are immediately deleted. The system is highly secure and addresses the security vulnerabilities in the current banking and payment systems, both online and offline such as ATM machines.

Abstract: A biometric authentication platform uses fault-tolerant distributed computing to determine if a supplied biometric live scan and template are from the same person. Features provide additional protection for biometric data. The template and live scan may be encrypted using a symmetric encryption key. The encrypted template and live scan may be sent with copies of the symmetric key, each copy further encrypted by a public key associated with one processor's public-private key pair. Each processor may decrypt a copy of the symmetric key, which may then be used by the processor for decrypting the live scan and template for matching. A decentralized user ledger may store an encrypted copy of the biometric template, with the key stored locally in a registered device. Alternatively, a decentralized user ledger may store a hash of the biometric template, for verification of a template that is maintained on a registered device.

Abstract: A biometric authentication platform uses fault-tolerant distributed computing to determine if a supplied biometric sample and a template sample, which may be stored in a registry, are from the same person. Samples may be subdivided and assigned to Sub-Sample Processing Clusters for processing in parallel to determine sub-results. A consensus authentication result may then be determined by the processing cluster based upon the sub-results.

Abstract: A biometric authentication platform (10) uses fault-tolerant distributed computing to determine if a supplied biometric sample and a sample stored in a registry are from the same person. A collection of reference samples may be maintained in a distributed user ledger (115), and results of matching are stored in a separate distributed authentication ledger (125). Coordinated use of both ledgers (115, 125) enable biometric authentication of registered users (140) in real time. Variations enable use of a user ledger (115) without an authentication ledger (125), and use of an authentication ledger (125) without a user ledger (115). Either or both ledgers (115, 125) may be shared, private, or combinations of shared and private. Secondary channel audits verify reliability of nodes within a network. Samples may be subdivided and processed in parallel. Sample encryption may be maintained for each processor in a node network.

Abstract: A computing platform is described to match a palm print digital representation to a palm print template. The platform includes logic causing an illumination source to illuminate a field of view of a camera with an emission spectrum predominately in a wavelength range less than 485 nm; capturing a set of images using the camera of a palm during the illumination; processing the set of images to determine a set of identifying features of the palm according to intensity gradients in the wavelength range of the illumination source; and comparing the set of identified features with enrolled palm prints to identify the palm.

Abstract: A system of token-based user authentication for the purpose of authorizing user access to protected resources, such as web applications, computer systems or computer controlled devices. The system utilizes a personal trusted device (PTD), which is owned and operated by one specific user, to establish secure communication channels that are subsequently used to pass user credentials to authentication service. Association of a PTD with servers controlling access to resources is performed by publishing and capturing unique tokens via sensors embedded in PTD, such as an optical camera.

Abstract: A system is provided for offer redemption of a retailer. A service provider includes one or more servers with engines and attached storage. The service provider is configured to be in communication with a mobile application running on a user mobile device of a user. The service provider is configured to be in communication with an advertiser and the retailer. The service provider is coupled to one or more processors with logic that enable an advertiser to create an offer campaign with details of the offer campaign stored in the storage. The details including at least one of, offer distribution rules and offer redemption rules. The one or more processors review transaction line items of the offer and making a determination to push or not push the offer redemption to a retailer check-out system.

Abstract: An offer redemption system is provided with least one computing device. An offer clearinghouse application is executable in the at least one computing device. The offer clearinghouse application includes, (i) one or more processes that receives details of an offer including at least one product to which n offer applies and at least one offer restriction for the offer, (ii) one or more processors that provides for distribution of the offer to users on behalf of an advertiser and (iii) one or more processors that provides for redemption of the offer with a retailer. A retailer interface receives, at a time of offer redemption, information to identify a retail transaction and line item used by an offer validation.
