Embodiments disclosed are directed to a computing system that performs steps for entity integration. The computing system receives, from a user device, an electronic request to associate a first online account of a user associated with a first entity with a second online account of the user associated with a second entity. The computing system authenticates the user device to verify that an identity of the user is authentic. The computing system determines whether the second online account exists and, if so, identifies a match between a first user property of the first online account and a second user property of the second online account. Based on the identified match, the computing system links the first online account with the second online account and updates, based on a first online account property of the first online account, a second online account property of the second online account.

A method begins by monitoring exchange item transactions occurring in an exchange item marketplace network. The method continues with generating trend information based on the monitored exchange item transactions and determining attributes for a targeted marketing program based on the trend information. The method continues with identifying a subset of buyer computing devices based on the attributes. The method continues by generating offer information based on the targeted marketing program and sending the offer information to the subset of buyer computing devices. When receiving a purchase request from a buyer computing device, the method continues by generating an exchange item request regarding an exchange item and sending the exchange item request to a branded server associated with the exchange item. The method includes receiving offer exchange item information from the branded server and sending at least a portion of the offer exchange item information to the buyer computing device.

In one embodiment, a payment service system-implemented method of assigning payment card numbers for individual user accounts associated with the payment service system includes receiving a request, in the context of an authorization for a payment transaction, to assign a payment card number to a user account associated with a user of the payment service system. The method includes retrieving, from a database associated with the payment service system, an account record associated with the user account. The method includes determining that the user account is not associated with an active payment card number. The method includes identifying an unassigned payment card number and modifying the account record to assign the unassigned payment card number to the user account as an active payment card number. The method includes authorizing the payment transaction using the active payment card number, causing a modification to an account balance of the user account.

The present disclosure involves systems, software, and computer implemented methods for generating new credit accounts for immediate availability for use in current online transaction. One example process includes identifying a request to perform a credit application process associated with a particular user via a client application. A first signal can be transmitted that includes a redirect instruction for the client application to a credit application site to perform a credit application process. A second signal can be transmitted that includes a merchant-specific identifier of the particular user and a request to perform the credit application process. A third signal can be received from the credit application site that includes an approval, a payment credential associated with a newly created credit account, and the merchant-specific identifier of the particular user. The payment credential can be associated with the user profile of the user corresponding to the merchant-specific identifier.

Methods, systems, apparatus, and non-transitory computer readable media are described for using a vehicle as a payment device. Various aspects may include receiving a selection of a stored financial card or financial account at a vehicle head unit. The selected financial card or financial account may be transmitted to a point-of-sale (POS) terminal for making a payment by transmitting a tokenized card number to the POS terminal. The tokenized card number may be transmitted over a very short-range communication link to ensure that the transmission is secure. For example, electronic circuitry may be attached to the exterior of the vehicle, where the electronic circuitry may be within a threshold distance (e.g. one inch, three inches, six inches, one foot, three feet, etc.) of the POS terminal. The tokenized card number may be transmitted from the vehicle head unit to the electronic circuitry and then to the POS terminal.

In general, according to one embodiment, a transaction certification system includes a transaction processing apparatus and a server. The transaction processing apparatus outputs encrypted data including transaction certification data for certification of a transaction executed on the transaction processing apparatus. The server receives the encrypted data from a first terminal apparatus that reads the encrypted data that has been output by the transaction processing apparatus. The server acquires a first user identifier identifying a user of the first terminal apparatus sending the encrypted data. The server stores the transaction certification data of the encrypted data in a storage device. The transaction certification data is stored in correlation with the acquired user identifier. The server receives a second user identifier from a user requesting a transaction certification, and then transmits the transaction certification data to a second terminal apparatus associated with the second user identifier.

Systems and methods of the present disclosure may collect data associated with a user activity. The data may be transmitted from an app running on a computing device with a user account authenticated by the computer-based system. The system may calculate a carbon footprint of the user activity based on the data associated with the user activity. An amount of carbon credits may be assigned to a user account authenticated with the computer-based system based on the calculated carbon footprint of the user activity. A transaction may be written to a blockchain retiring the amount of carbon credits in response to a request to offset a carbon footprint.

Aspects described herein may allow for authenticating a user by generating a customized set of authentication questions based on patterns that are automatically detected and extracted from user data. The user data may include transaction data collected over a period of time. By automatically detecting user patterns that correspond to user behavior over a period of time, an authentication system may be able to generate information that is recognizable to an authentic user but difficult to guess or circumvent for any other user.

A system for managing and using digital financial assets, such as cryptocurrency uses multiple independent devices that mutually cooperate to control cryptocurrency assets in a secure manner. Each of these devices may store a unique private key associated with the cryptocurrency assets, which may be configured such that a certain minimum number of these private keys are required to transfer the cryptocurrency assets. The use of multiple private keys spread across multiple distinct devices may reduce the likelihood of loss stemming from a hardware failure or reduce the likelihood of an attacker successfully gaining access to the cryptocurrency assets. In addition, selection of the devices to be used for storing these private keys, as well as how many private keys are required to authorize a transaction, may be tailored to balance a user's preferences for reliability of access versus security and for third-party custody versus self-custody.

Methods, systems, and apparatuses are described herein for improving computer authentication processes by dynamically adjusting questions presented during authentication. A request for access to an account may be received. A first authentication question may be generated based on a first transaction of a plurality of transactions associated with an account. Based on whether a response to the first authentication question is correct or not, a second or third transaction of the plurality of transactions may be selected, and a second authentication question might be generated based on the selected transaction. It may be determined whether to provide access to the account based on a response to the second authentication question.
