Abstract: In relation to a transaction request, a payment processing system monitors a flow of transaction data across a plurality of communicatively-coupled transaction processing components. The payment system can detect an interruption or stall in the flow caused by a system fault or user error or inactivity. In response to a detected interruption or stall, the payment system determines an active or dormant status of a payment application executing on a user mobile device. The system assigns an extant or abandoned status to the transaction request based on the determined status of the payment application. The payment system voids or revives the transaction request based on an assigned status of the transaction request.

Abstract: A payment processing system can detect an attempted re-initiation of a payment transaction for the same purchase of an item or service. In some examples, the system compares initial transaction data against re-initiated transaction data to identify the attempted duplicated payment. Based on the identified attempted duplicated payment, initiating a payment deduplication phase by generating a potential payment duplication alert for presentation at the POS terminal device and/or in the user interface of a mobile device.

Abstract: Various device attributes associated with a current event may be obtained. Similarity metrics may be determined that indicate a degree of similarity between the device attributes that are associated with the current event and stored device attributes that are associated with previous events and previously created fuzzy device identifiers. A fuzzy device identifier may be assigned to the current event based at least in part on a comparison of the similarity metrics with a threshold. If none of the similarity metrics compare favorably with the threshold, then a new fuzzy device identifier may be created for the current event. However, if at least one of the similarity metrics compares favorably with the threshold, then the previously created fuzzy device identifier whose stored device attributes are most similar to the device attributes that are associated with the current event may be assigned to the current event.

Abstract: Systems and methods for indexing and searching health data are disclosed herein. In some embodiments, a method for querying patient records includes receiving a search input that specifies a plurality of events, one or more temporal relationships between the events, and inclusion and/or exclusion criteria. An index query is constructed based at least in part on the plurality of events within the search input. The index query is then executed against an inverted index to identify matching patient records. One or more temporal constraints can be solved against the identified patient records. Finally, patient records satisfying the constraint(s) are returned.

Abstract: A machine may be configured to facilitate partial reductions of an amount by generating and providing a graphical user interface that enables a user to specify one or more partial reductions of the amount, thus defining or otherwise controlling how the amount is to be reduced in stages by such partial reductions. For example, in situations where a total amount is to be reduced in stages by multiple partial reductions, the generated and provided graphical user interface may be operable to specify each stage of reduction by enabling the user to select a corresponding account for each stage of reduction. The corresponding account may be selected from among a set of multiple available accounts, each with a respectively corresponding available amount, any of which may be an accumulated amount gathered from a periodic series of transactions authorized to occur periodically.

Abstract: A security mechanism, e.g., a computing system, security server, can effectively serve as a centralized security mechanism, e.g., a computing system, security server, for an ecosystem that can include diverse clients and servers. The security mechanism can obtain redirected requests for services, authenticate credentials of a client and generate a (client-side) token that can be provided by the client to the server for verification of the identity of the client. The security mechanism can also obtain a token from a server that can be similar to a (client-side) token provided to a client and then generate a (server-side) token that can be provided to a server. The server-side token can include authorization information that allows access to one or more services of one or more other servers.

Abstract: Geotag data embedded in a photograph is converted to a multilevel hierarchical place name tag, which is a new data structure. Higher hierarchy levels correspond to larger geographical regions. Lower hierarchy levels correspond to smaller geographical regions. The geotag data is used to locate the photograph on a map. A cluster of nearby photographs is defined and represented by a consolidated pin. The identification and quantity of clustered photographs depends on the relative locations of the photographs and the map zoom level. A consolidated pin label is defined based on which hierarchy levels, if any, have a common place name tags. In some cases the consolidated pin label includes only place name tags that are shared amongst all clustered photographs. In other cases the consolidated pin label includes a short list of mutually exclusive place name tags. The consolidated pin label is displayed on the map near the consolidated pin.
