Characterizing groups based on geolocations reported by populations of mobile computing devices
Provided is a process including segmenting a representation into a set of tiles and obtaining a set of geolocations. The process includes, for each tile, determining a respective amount of devices within the respective tile to form a set of weights. The process also includes assigning each tile of a subset of the set of tiles with a set of groups based on the set of weights, building a first map based on the set of groups, and building a second map by traversing the first map. The process also includes determining a first and second subset of devices by traversing the second map, determining whether a second tile is to be assigned to a first or second group based on the first and second subset of devices, assigning the second tile to the first group, and building a region map comprising the set of groups. |

Customer experience artificial intelligence management engine
In some implementations, an event timeline that includes one or more interactions between a customer and a supplier may be determined. A starting value may be assigned to individual events in the event timeline. A sub-sequence comprising a portion of the event timeline that includes at least one reference event may be selected. A classifier may be used to determine a previous relative value for a previous event that occurred before the reference event and to determine a next relative value for a next event that occurred after the reference event until all events in the event timeline have been processed. The events in the event timeline may be traversed and a monetized value index assigned to individual events in the event timeline. |

Methods and apparatus for payment transfer fraud detection
This application relates to apparatus and methods for identifying fraudulent payment transfers. In some examples, a computing device determines payment transfer initiation features, and payment transfer reception features, based on previous payment transfer data. The computing device may train a machine learning fraud detection model with the payment transfer initiation features, and may train a machine learning fraud detection model with the payment transfer reception features. Once trained, the computing device may employ the machine learning fraud detection models to identify fraudulent payment transfers. For example, the computing device may determine whether a payment transfer is fraudulent when the payment transfer is initiated. Assuming the payment transfer is allowed, the computing device may determine whether the payment transfer is fraudulent when the payment is being received. In some examples, the computing device prevents completion of the purchase transaction if the payment transfer is determined to be fraudulent. |

Computerized-method and system for predicting a probability of fraudulent financial-account access
A computerized-method for predicting a probability of fraudulent financial-account access, is provided herein. The computerized-method includes a. building a Machine Learning (ML) sequence model; b. implementing a forward-propagation-routine in an encapsulated environment that runs applications to mimic a process of the ML sequence model. The forward-propagation-routine is mimicking processing of a chronical-sequence of a preconfigured number of non-financial activities sequence vector, layer by layer to generate a fraud probability score and using weights and biases which were extracted from each layer of the trained ML sequence model; and c. exporting the extracted weights, biases to a persistent storage and converting the forward propagation routine to an executable for integration with a Fraud Management System that is operating the integrated executable to predict a probability of fraudulent financial-account access by providing a fraud probability score to each chronical-sequence of a preconfigured number of non-financial activities. |

Method and system for detecting fraudulent transactions
A method for detecting fraudulent transactions includes generation of a graph including a plurality of nodes and a plurality edges between the plurality of nodes based on historical transaction data of a plurality of historical transactions. The plurality of nodes include a set of merchant nodes and a set of consumer nodes. A set of static features and a plurality of dynamic features are determined based on the historical transaction data and the generated graph, respectively. A neural network is trained based on the set of static features and the plurality of dynamic features for detection of transaction fraud. The neural network is used to detect a first transaction as one of a fraudulent transaction or a legitimate transaction based on first transaction data of the first transaction. |

System and method for providing merchant in-context checkout
Methods and systems for providing merchant in-context checkout are described. A user is authenticated based on credentials received from a first application running on a computing device. An authentication code is provided to the first application. A signed verifier and the authentication code is then received from a second application running on the computing device. The authentication code and the signed verifier received from the second application are then validated, and a device token is provided to the second application upon validation. The device token is exchangeable by the second application for an access token that is usable for making payment calls from the second application. |

Systems and methods for distributed enhanced payment processing
A distributed enhanced payment processing system includes a merchant point of sale (POS) terminal system and a remote payment management system. The POS terminal system initiates a transaction that includes receiving a payment amount, a purchaser account identifier, a virtual electronic payment indicator, and a merchant ID via a payment client. Subsequently, the POS terminal system outputs the transaction to the remote payment management system which generates a token for the transaction. The payment management system then provides the purchaser account identifier, a merchant account identifier, and the payment amount to a remote virtual electronic payment (VEP) entity system. Upon receiving a VEP entity system response, the payment management system outputs the response and token to the POS terminal system. |

Third party products and services via ATM
A computer system and a transaction machine, such as an automated teller machine (ATM), can provide for any payor to make a payment to a payee at the transaction machine. The transaction machine provides the payor a user interface to enter a passcode that uniquely identifies the payment transaction. The passcode can be generated by a provider computing system associated with the transaction machine and provided directly to the payee or through the payor prior to the transaction. The transaction machine provides the payor a user interface to enter an amount. The transaction machine also provides the payor the ability to make a payment at the transaction machine using various modes of payment such as cash, credit card, or cryptocurrency. The transaction machine verifies that the payment matches the user selected amount, and sends a payment notification to the payor. |
