Abstract: Systems and methods for verifying users in connection with transactions using biometric payment card devices are disclosed. One exemplary biometric payment card device generally includes a card body, a fingerprint sensor, a modem, and a processor coupled to the modem and the fingerprint sensor, where each of the fingerprint sensor, the modem, and the processor are disposed on the card body. The processor of the payment card device is configured to capture, via the fingerprint sensor, a fingerprint of a user associated with the payment account, compare the captured fingerprint to a reference fingerprint stored in memory in communication with the processor, and then compile and transmit, by the modem, an authentication result to an issuer of the payment account and/or a payment network associated with the payment account in response to the user being authenticated, or not, based on the comparison of the captured fingerprint and the reference fingerprint.

Abstract: Systems and methods for verifying users in connection with transactions using payment card devices are disclosed. One exemplary payment card device generally includes a card body, a modem, and a processor disposed on the card body and coupled to the modem. The processor, then, is configured to determine a location of the payment card device, via at least the modem, based on multiple signals from multiple towers (and/or routers) associated with a telecommunication network, and transmit, by the modem, via one of the multiple towers and/or routers, location data indicative of the determined location to at least one of an issuer of the payment account and/or a payment network associated with the payment account.

Abstract: Methods and apparatus for enrolling a biometric payment card. In an embodiment, a biometric payment card processor receives fingerprint image data of a cardholder's finger during an initial purchase transaction, extracts digital information from the fingerprint image data and generates current fingerprint template data. The biometric payment card processor then compares the current fingerprint template data to data stored in a memory, determines that the current fingerprint template data did not match any data stored in the memory, transmits cardholder identification data and an authentication failure message to a payment card reader device, receives enrollment instructions from the payment card reader device, and then stores, in response to the instructions, the current fingerprint template data as enrollment fingerprint template data in the memory.

Abstract: Methods are provided for achieving consensus among an order in which write requests are received by various ones of a plurality of nodes in a distributed system using a shared data structure. The plurality of nodes are organized into groups of nodes and successively larger groupings of groups, based on physical proximity. A consensus protocol is used to achieve consensus among groups of nodes, and then among the groupings of groups of nodes in a logical tree structure up to a root level virtual node.

Abstract: Systems and methods are provided for distributing parcels to recipients based on location data associated with the recipients. One exemplary method includes generating and storing a shipping file for the recipient, where the shipping file includes an identifier for a portable communication device associated with the recipient and a defined geographic region for the recipient, and retrieving location data for a location of the portable communication device based on the identifier associated with the portable communication device. The method also includes determining whether the location of the portable communication device is within the defined geographic region. The method then further includes directing an entity associated with the parcel to ship the parcel to the recipient when the location is determined to be within the defined geographic region, and directing the entity to hold shipment of the parcel when the location is determined to be outside the defined geographic region.

Abstract: A network gateway is provided for routing data flows across a plurality of network connections, the network gateway including a plurality of network interfaces for transmitting data over the plurality of network connections, the plurality of network interfaces including a first network interface; at least one processor configured for: transmitting a sequential burst of packets across the first network interface; based on timestamps recorded when packets in the sequential burst of packets are received at a receiving node, and the size of the packets, generating a bandwidth of the first network interface; and routing a data flow of sequential packets across the plurality of network connections based on the generated bandwidth of the first network interface.

Abstract: This invention relates to a system and methods for determining the placement of an object in a distributed key-value store by mapping the object to nodes in multidimensional hyperspace. A search function supports efficient object retrieval, even when the search query requests multiple objects and specifies them through non-primary keys. In response to a search query, the search is translated into hyperregions in the hyperspace to determine the set of nodes that hold the queried data object. The number of contacted nodes and the number of scanned objects are significantly reduced in comparison to prior art techniques.

Abstract: An efficient fault-tolerant event ordering service as well as a simplified approach to transaction processing based on global event ordering determines the order of interdependent operations in a distributed system. The fault-tolerant event ordering service externalizes the task of tracking dependencies to capture a global view of dependencies between a set of distributed operations in a distributed system. A novel protocol referred to as linear transactions coordinates distributed transactions with Atomicity, Consistency, Isolation, Durability (ACID) semantics on top of a sharded data store. The linear transactions protocol achieves scalability by distributing the coordination task to only those servers that hold relevant data for each transaction and achieves high performance by serializing only those transactions whose concurrent execution could potentially yield a violation of ACID semantics.
