Abstract: Methods and systems for mobile cardholder authentication are provided. An access device can obtain interaction data produced during an interaction between a user and the resource provider computer in which the user attempts to obtain a resource from a resource provider and user device data comprising a cryptogram and supplemental data from the user device or another user device operated by the user. The cryptogram of the user device can be validated and the interaction data and user device data can be compared to determine that the user interacting with the access device is the same user as the user that interacted with the resource provider computer. The access device can provide an indication that the resource will be provided to the user responsive to determining that the user interacting with the access device is the same user as the user that interacted with the resource provider computer.

Systems for processing CNP transactions are also disclosed.

Abstract: A method of determining fraud includes: receiving a transaction request associated with a first payment transaction between a merchant and a user from a merchant system; generating a first risk score based on the transaction request and a first set pot of transaction data received prior to the transaction request; processing a transaction request approval based on the first risk score not satisfying a first threshold; receiving a risk score request associated with the first payment transaction, where the risk score request is received after the transaction request has been approved; generating a second risk score based on a second set of transaction data received after the first risk score is determined; and automatically classifying the first payment transaction as potentially fraudulent in response to determining that the second risk score satisfies a second threshold.

Abstract: Described herein is a system in which an electronic record is stored on a distributed environment with respect to an item. In this system, transactions may be conducted for an item in an anonymous fashion. In some embodiments, a first user may input an item identifier associated with an item as well as an indication of an action to be performed with respect to that item. The identifier may be transmitted to a blockchain network, which may use that identifier to locate a blockchain associated with the item. A blockchain may include a series of transaction records associated with the item, each of which is signed using a private key. Upon performance of the indicated action, the blockchain network may generate a new transaction record, append that transaction record to the blockchain, and sign the transaction record.

Abstract: A method for maintaining user privacy in advertisement networks may include receiving first persona data associated with a first user from at least one publisher system. The first persona data may be generalized to form first generalized persona data. A session key may be generated. The first generalized persona data and the session key may be encrypted with a first public key of an advertisement network system to form a first ciphertext. The first ciphertext and first user identity data may be communicated to a mediator system. The first user identity data may be associated with first user's identity. A first encrypted targeted advertisement may be received based on the first generalized persona data from the advertisement network system via the mediator system. The first encrypted targeted advertisement may be decrypted with the session key to form a first targeted advertisement. A system and computer program product are also disclosed.

Abstract: Provided are a system, method, and computer program product for secure payment device data storage and access. The method includes storing payment device data associated with a payment device of a user and generating a unique uniform resource locator (URL) associated with the payment device. The method also includes transmitting the unique URL to an application provider system through a first communication channel and receiving a data access request from the client device via the unique URL through a second communication channel separate from the first communication channel. The method further includes, in response to receiving the data access request, verifying an identity of the user by executing a step-up authentication protocol. The method further includes, in response to verifying the identity of the user, transmitting a data access response including the payment device data to the client device through the second communication channel.

Abstract: Described herein are a system and techniques for enabling user control over usage of their information by data consumers, even when untrusted parties are involved, while also preventing collusion between the untrusted party and a data consumer. A user's information may be collected by a client device and provided to a host server. An encrypted version of the user's information may be stored at the host server so that it is processed on a private enclave of the host server. When the data is to be provided to multiple data consumers, the data may be encrypted for each of the data consumers and may be released to each of those data consumers simultaneously once confirmation has been received that the data has been made available to each of the data consumers.

Abstract: A processing system for fuel transactions analyzes transactions for symbols indicating a purchase amount and directs information about the purchase to a loyalty platform. The loyalty platform may identify and communicate in real time or near real time with a personal device associated with the purchaser of the fuel. A user interface of the personal device may allow the purchaser to review and select options for processing the fuel purchase using value from a loyalty program account. The selected option may be used to modify fuel purchase parameters prior to settlement of the transaction or simply add points to the user loyalty program account.

Each server may have a dedicated database and receive information from relevant sources including various reporting agencies.

Abstract: A user initiates a transaction by providing identification data at an access device. Certain elements of a validation identity token, such validation keys, may be distributed among several remote server computers. After the elements are retrieved during the transaction, the validation identity token may be generated using the retrieved elements. The validation identity token may indicate whether the user is authenticated. No single entity can possess all elements utilized to generate the validation identity token, which mitigates risk of the validation identity token being compromised. In some embodiments, the validation identity token may be a chromatic identity token, which may indicate validity by color.

Abstract: Systems and methods are described for pre-authentication access request screening. A server computer may receive a request for access to a resource comprising access data. The server computer may transmit, to an authentication computer, an authentication request message comprising at least a subset of the access data and receive an authentication response message comprising authentication data. The server computer may determine an access score based on the authentication data. Alternatively, the server computer may determine the access score based on the access data without using/receiving authorization data. The server computer may generate an access indicator based on the access score. The server computer may prepare and transmit an authorization request message comprising the access indicator to an authorization computer. The authorization computer may approve or decline the access to the resource based on the access indicator.

Abstract: A mobile merchant may have an entrance area which may have a geo-fence area which has a communication device to communicate with a payment device of a user when in or passing through the geo-fence area such as getting on a bus. The location of the start of the communication may be noted and stored as a first or starting location. When the user gets off the mobile merchant, the communication between the communication device and the payment device may end. The location of the end of the communication may also be noted and stored as a second or ending location. The first and second location and data from the payment device may be communicated to a billing computing device which may determine a price for the trip from the first location and the second location and the price may be applied to the payment account represented by the payment data.
