System, device, and method of detecting business email fraud and corporate email fraud. A method includes: receiving a user request to perform an online transaction on behalf of a corporate entity; generating a notification that requires the user to indicate whether he obtained managerial authorization for performing that online transaction on behalf of that corporate entity; monitoring user gestures and user interactions in response to that notification; receiving a positive answer from the user; performing an analysis of user gestures and user interactions, and generating a signal indicating a determination that the positive answer from the user is false, based on analyzed metrics that correspond to characteristics of the user gestures and user interactions; blocking or unauthorizing, at least temporarily, that online transaction that was requested on behalf of that corporate entity.

A computer-implemented method of recording an agreement between a requesting party and a confirming party on a blockchain, wherein the method is performed by the requesting party and comprises: generating a request transaction, wherein the request transaction comprises an input signed by the requesting party, and at least a first output comprising a cryptographic puzzle based on a first data item known to both the requesting and confirming parties, wherein the first data item represents the agreement; and causing the request transaction to be transmitted to one or more blockchain nodes.

Examples for determining printing device functionality based on consumption and payment are described herein. In some examples, signals indicative of an amount of utilized print consumable by a printing device and signals indicative of payment for the amount of utilized print consumable are received at a computing device. Signals to cause the printing device to alter a functionality based on the signals indicative of an amount of utilized print consumable and the signals indicative of payment for the amount of utilized print consumable are transmitted by the computing device.

A method for preventing an unauthorized transaction indicative of scalping includes: receiving transaction data for a first payment transaction including one or more product identifiers associated with one or more products purchased in the first payment transaction and consumer identification data; updating a consumer profile based on the one or more product identifiers, wherein the consumer profile is identified using the consumer identification data; receiving a transaction message for a second payment transaction including at least one product identifier included in the one or more product identifiers and at least one consumer data value that is also included in the consumer profile; determining a suspicion score for the consumer profile above a predetermined threshold value; and transmitting an authorization response message for the second payment transaction including a response code indicative of rejection of the second payment transaction.

A method may include presenting a user interface (UI), to a user, in a first mode on a client device, the UI including a list portion, the list portion including a plurality of transactions associated with respective activity on a user account, and the client device including an input device; receiving an indication of a first user action on a transaction presented in the list portion of the UI; in response to receiving the indication, updating a section of the list portion corresponding to the transaction, the updating including revealing a set of options for the transaction; receiving an indication of a second user action corresponding to activation of an option of the set of options; and in response to receiving the indication of the second user action, transitioning the UI from the first mode to a second mode, the second mode including a chatbot interface instantiated with respect to the transaction.

An information processing device obtains order identification information capable of identifying an order placed by an order-placing person, transmits, as payment information, the order identification information, causes a printing process of a print medium to be executed, the print medium being capable of identifying the order identification information and gives, to another information processing device when an additional order placed by the order-placing person is received, an invalidation command which invalidates the order identification information in such a way that a payment with respect to the order identification information on an order not paid yet and placed by the same order-placing person is disabled.

A real-time third-party payment system accepts payments to a lender from third-party merchants in real-time. The payment system may receive real-time payment information from the third-party, and various services within the payment system validate the customer account information, create a payment, store the payment in a database, and post the payment to a real-time ledger. The payment system may also receive an end-of-day file including file-based payment information. The file-based payment information may be verified against the real-time payments stored in the database. Upon validation, the payment system creates a file based payment and posts the file-based payment to a file-based ledger. The payment system may detect fraud, errors, and other discrepancies in real-time payments and make corrections based on settlement rules and self-healing rules provided by the third-party.

A non-transitory computer-readable storage medium storing a transaction program that causes at least one computer to execute a process, the process includes transmitting transaction information to a user terminal; receiving result information acquired by processing payment of a transaction of the transaction information by a server, from the user terminal, the result information including identification information indicating the payment; storing the identification information associated with the transaction information in the one or more memories; and outputting a receipt including identification information.

A first security element is for transmitting an electronic coin data set to a second security element. The electronic coin data set is registered in a coin register of a payment system. The method has the steps of: setting a status of the electronic coin data set from the security element to an inactive status; transmitting the electronic coin data set from the first security element to the second security element; checking whether a receipt confirmation from the second security element has been received in the first security element; and deleting the transmitted electronic coin data set if the checking step results in that the receipt confirmation has been obtained by the first security element. The aforementioned relates to a payment system, a coin register, a security element, and a terminal for transmitting electronic coin data sets.

A computer-implemented method, a computer program product, and a computer system for preventing scams in commerce transactions. The computer system identifies a critical decision-making process of a user in a commerce transaction that involves exposing personal data. The computer system receives current stress factors of the user. The computer system calculates a current stress score of the user, based on the current stress factors, by using a machine learning model that correlates behavioral patterns of the user and stress levels of the user. The computer system determines an abnormal level of the current stress score, based on predetermined thresholds for different abnormal scores. The computer system determines a privacy protection level in the critical decision-making process, based on the abnormal level. The computer system takes an action for preventing scams in the commerce transaction, based on the privacy protection level.
