Methods and apparatus consistent with the present disclosure allow a customer or payor to select from a plurality of nearby vendors or payees when a computing device of the payor is physically close to electronic devices of the payees. Payee devices and locations of those payee devices may be identified and displayed on a display of a payor device. Once displayed, a specific payee device may be selected by the customer and an order for a product or service may be sent to the selected payee device from the payor device. After the product or service has been provided to the customer, information that confirms that purchase may be sent to any of the selected payee device, the payor device, or a payment processing computer and funds to pay for the product or service may be deposited into an account of the payee based on the confirmation.

Systems, methods, and computer-readable media for achieving privacy for both data and an algorithm that operates on the data. A system can involve receiving an algorithm from an algorithm provider and receiving data from a data provider, dividing the algorithm into a first algorithm subset and a second algorithm subset and dividing the data into a first data subset and a second data subset, sending the first algorithm subset and the first data subset to the algorithm provider and sending the second algorithm subset and the second data subset to the data provider, receiving a first partial result from the algorithm provider based on the first algorithm subset and first data subset and receiving a second partial result from the data provider based on the second algorithm subset and the second data subset, and determining a combined result based on the first partial result and the second partial result.

Transaction-enabled systems and methods for royalty apportionment and stacking are disclosed. An example system may include a plurality of royalty generating elements (a royalty stack) each related to a corresponding one or more of a plurality of intellectual property (IP) assets (an aggregate stack of IP). The system may further include a royalty apportionment wrapper to interpret IP licensing terms and apportion royalties to a plurality of owning entities corresponding to the aggregate stack of IP in response to the IP licensing terms and a smart contract wrapper. The smart contract wrapper is configured to access a distributed ledger, interpret an IP description value and IP addition request, to add an IP asset to the aggregate stack of IP, and to adjust the royalty stack.

The present disclosure generally relates to techniques for managing contextual transactions. In some examples, at a sender electronic device, a first user provides authorization to purchase an item for a second user. In some examples, at a recipient device, the second user selects one or more attributes for the item and requests to claim the item. In some examples, an electronic device displays a representation of an item and a purchase affordance for purchasing the item using a payment system that is available on the electronic device.

A data processing method and apparatus based on a blockchain network, and a computer device. The method includes acquiring a transaction request, the transaction request carrying transaction data and reference signature data corresponding to the transaction data; validating the transaction data and the reference signature data; determining a matching node device from a target node device if the transaction data and the reference signature data are validated, and acquiring a signing key of the matching node device; determining data to be signed according to the transaction data, and signing on the data to be signed using the signing key of the matching node device to obtain endorsement signature data; and transmitting the endorsement signature data to the management device, wherein the management device generates a transaction block according to the endorsement signature data and the transaction data.

Embodiments relate to systems, apparatuses, and methods for performing access interactions between a user device and an access device. A method comprises receiving, by an access device with a single universal kernel comprising a plurality of interaction functionalities and a plurality of sub-kernels, data comprising a kernel identifier identifying a requested kernel of a plurality of kernels to perform an interaction. The access device with the single kernel may determine a first sub-kernel of a plurality of sub-kernels corresponding to an interaction functionality based on the kernel identifier. The access device with the single universal kernel may then process the interaction according to the interaction functionality corresponding to the determined sub-kernel.

A system and method for preventing hacking of blockchain is proposed. The system includes a cryptocurrency owner configured to own a cryptocurrency wallet storing a cryptocurrency, a public key, and a private key, and capable of setting monitoring-subjected data and monitoring-excluded data, a hacking countermeasure system configured to check status of the cryptocurrency wallet by being connected to the cryptocurrency owner to receive the cryptocurrency and the public key, invalidate a hacking transaction when the hacking transaction matching the monitoring-subjected data is received, and allow the cryptocurrency to be traded by opening the cryptocurrency wallet with the private key and process transaction details into a block file when a monitoring-excluded transaction matching the monitoring-excluded data is received, and a blockchain network configured to receive the block file from the hacking countermeasure system and duplicate the block file into a plurality of block files to distribute and store each block file.

The present invention provides a method for tracking and managing power supplying devices and a blockchain-based system to perform such tracking and monitoring. The method comprises the steps of retrieving recorded characteristic data that is associated with an existing product identification from a blockchain, verifying such recorded characteristic data, generating a new product identification that is connected to the existing product identification and recording the new product identification and new characteristic data in the blockchain. The system comprises a blockchain and a middleware computer to perform the above-mentioned steps. Also provided herein is a blockchain-based system for monitoring and renting a power supplying device.

An artwork management method executed by one or more computers is provided. The artwork management method includes detecting, by a first computer included in the one or more computers, artwork included in a website, determining, by the first computer, whether or not a purchase transaction indicating purchase of the artwork detected is recorded in a blockchain network, and transmitting, by the first computer, a report indicating discovery of unauthorized use of the artwork, in a case where the first computer determines that the purchase transaction is not recorded. According to one aspect, the artwork management method suppresses illegal use of artwork while maintaining accessibility of the artwork.
