This disclosure provides systems, methods and apparatuses for identifying fraudulent accounts associated with an electronic payment service. In some implementations, a computing device may retrieve a data set including a number of attributes for each of a multitude of accounts, and may construct a plurality of different graphs each based on a unique set of the attributes. Each graph may include a plurality of nodes linked together by a multitude of edges, where each node identifies a corresponding account and each edge indicates one or more of the corresponding attributes that are common to a pair of accounts. The computing device may determine a likelihood of each graph correctly identifying fraudulent accounts by analyzing groups of nodes connected to each other by corresponding groups of edges using historical account data, and may select the graph having the greatest determined likelihood to predict whether any of the accounts is fraudulent.

In some implementations, a printing system may include a card printer that includes a printing controller and a marking device. The card printer may be configured to receive a first printing instruction or a second printing instruction associated with printing an account identifier on a card. The card printer may receive one of the first printing instruction or the second printing instruction based on whether a risk score, associated with the account identifier, satisfies a threshold. The card printer may print a full account identifier, associated with the card, on a surface of the card based on receiving the first printing instruction. The card printer may print the card without the full account identifier on the surface of the card based on receiving the second printing instruction.

Systems and methods for rules-based decisioning of events are disclosed. In one embodiment, a method may include: creating an in-memory cache by parsing stored checkpoints, signals, and rules definitions; receiving a checkpoint request; prioritizing the checkpoint request; preparing a basic context, comprising a limited set of objects, for the checkpoint request; using the in-memory cached definitions, generating at least one of a raw signal, an engineered signal, and a secondary signal for the checkpoint request based on the basic context; using the in-memory cached definitions, executing rules on at least one of the basic context, the raw signal, the engineered signal, and the secondary signal to generate a list of potential decisions; reducing the list of potential decisions to a list of final decisions; publishing the final decisions and supporting data rules and signals execution details; and executing the final decisions.

Various aspects of the disclosure relate to automated generation and electronic delivery of digital representations of guaranteed financial instruments. A check generation service platform may process personal financial instrument images, along with user account information, to generate electronic representations of guaranteed financial products. Delivery of the guaranteed financial product may be performed as an electronic message comprising one or more of a bar code, a QR code, or an electronic token, and an electronic image that may be executed by a third-party computing platform.

Methods and apparatus provide improved stablecoins on a blockchain. The stablecoins are collateralized to fiat-based stablecoins that are loaned to borrowers from a lending pool. Loan payments received from the borrowers are divided into a first portion that buys fiat currency that over-collateralizes the stablecoins and a second portion that pays owners of the stablecoins a fixed rate of interest that does not vary over time.

Apparatuses, systems and methods are provided for generating enterprise data relating to roof damage associated with weather and hail data. The apparatuses, systems and methods may determine aspects of a proposed service related to roof damage (e.g., damage extent, repair estimates, or repair timing) based upon the enterprise data and the base-line probable roof loss confidence scores. The apparatuses, systems and methods may generate probable roof loss confidence score data based upon the base-line probable roof loss confidence scores, weather event data and hail event data.
