Based on the tuple sketches, the disclosed systems can determine one or more of a predicted cost per quantity of impressions, a predicted number of impressions, or a predicted expenditure for the digital-content campaign—according to user-input targeting criteria and expenditure constraints. |

System and method for understanding influencer reach within an augmented media intelligence ecosystem
Aspects of the present disclosure involve systems, methods, devices, and the like for augmented media intelligence using Artificial Intelligence (AI), Machine Learning (ML), Natural Language Processing (NLP), data analytics and data visualization. In one embodiment, a system is introduced that can retrieve real-time data from social media platforms to perform augmented media intelligence analysis and take real time actions if necessary. In another embodiment, the augmented media intelligence is design to use the machine learning and natural language processing capabilities and social currency means for understanding an influencers reach within the augmented media intelligence system via an influencer score. |

Intelligent merchant onboarding
Intelligent merchant onboarding is described. A service provider can determine first directive(s) that were presented to one or more first potential merchants that completed an onboarding process with the service provider and second directive(s) that were presented to one or more second potential merchants that did not complete the onboarding process. The service provider can train a data model based at least partly on the first directive(s) or the second directive(s). Based at least partly on receiving an indication that a potential merchant initiates the onboarding process, the service provider can determine information associated with the potential merchant. Based at least partly on the data model and the information, the service provider can intelligently determine an order that one or more directives are to be presented to the potential merchant such that a first directive of the first directive(s) is presented prior to a second directive of the second directive(s). |

Systems and methods for enhancing online user authentication using a personal cloud platform
A personal cloud authentication (PCA) system for authenticating an online user using device data stored on a personal cloud platform of the user is provided. The PCA system configured to build an authentication table using a user profile that includes at least user account information. The PCA system is also configured to receive transaction data associated with the user account information and store the transaction data within a database, wherein the transaction data includes at least an authentication request, a second primary user computing device identifier and a second secondary user computing device identifier. The PCA system is further configured to parse the transaction data, match the first primary user computing device identifier to the second primary user computing device identifier and the first secondary user computing device identifier to the second secondary user computing device identifier, generate an authentication response based on the match, and transmit the authentication response. |

Online fraud prevention using genetic algorithm solution
Online fraud prevention including receiving a rules set to detect fraud, mapping the rules set to a data set, mapping success data to members of the rules set, filtering the members of the rules set, and ordering members of the data set by giving priority to those members of the data set with a greater probability for being fraudulent based upon the success data of each member of the rule set in detecting fraud. Further, a receiver coupled to an application server to receive a rules set to detect fraud, and a server coupled to the application server, to map the rules set to a data set, and to map the success data to each members of the rules set. The server is used to order the various members of the data set by giving priority to those members of the data set with a greatest probability for being fraudulent. |

Risk monitoring system
Various embodiments of the present invention set forth techniques for monitoring risk in a computing system. The technique includes creating one or more risk objects, where each risk object of the one or more risk objects has a corresponding stored risk definition, the stored risk definition associating the risk object with raw machine data pertaining to the risk object, the raw machine data reflecting activity in an information technology (IT) environment. The technique further includes receiving a selection of a first risk object included in the one or more risk objects and receiving a first risk definition that corresponds to the first risk object. The technique further includes performing a search of the raw machine data according to the first risk definition, wherein a risk is identified based on the search of the raw machine data and performing an action based on identifying the risk. |

EMV-session data network and method of processing EMV-session data
An EMV-session data network includes a POS terminal and at least one computer server. The POS terminal is configured to receive ledger data and a cryptogram from a communications appliance, extract an account identifier from the ledger data, and transmit to the server an authorization request message that includes the account identifier, the authorization value and the cryptogram. The server is configured to transmit to the POS terminal an authorization response message that confirms that the cryptogram was generated by the communications appliance from the account identifier and the authorization value. The POS terminal is further configured to extract a token from the ledger data and to transmit to the server a loyalty rewards request message that includes the token. The server is further configured to initiate a points reward to an account that is associated with the token. |

Systems and methods for implementing blockchain-based content engagement platforms utilizing media wallets
Systems and methods are described for implementing blockchain-based content engagement platforms. In several embodiments, the content engagement platform includes a registry service which enables verified content creators to mint Non-Fungible Tokens (NFTs). In many embodiments, media wallet applications enable users to securely store NFTs and/or other tokens on their devices. In a number of embodiments, the media wallet applications collect data concerning media consumed by users and aggregate the media consumption data in a permissioned analytics blockchain. The manner in which the media consumption data is stored can enable users to control permission to access their personal data. In one embodiment, a media wallet is provided that can securely store NFTs, display a user interface through which user instructions concerning data access permissions are received, and cause media consumption data to be written to at least one immutable ledger in conjunction with a set of data access permissions. |
