A system and a method of data communication between a first computing device, associated with a first user, and at least one second computing device associated with a second user may include: receiving, by the first computing device, one or more data elements pertaining to details of a transaction request from the second computing device, via a voice channel; extracting said transaction request details by the first computing device; transmitting, by the first computing device, one or more authentication data elements of an electronic wallet module, comprised in the first computing device, to the second computing device, via the voice channel; and carrying out the requested transaction by the first computing device, based on the extracted transaction request details and the electronic wallet authentication data.

An option is set on a payment card of a card issuer. A request for payment for a transaction is received by a payment server of the card issuer from a merchant device/server. The payment server requests and receives a one-time token based on the option. An authorization indicating payment was successful is sent from the payment server to the merchant device/server with a flag set, the token, and a network address. Merchant device/server identifies the flag obtains the token and sends an e-receipt for the transaction along with the token to the network address. The e-receipt accessible from the network address by a consumer associated with the transaction. Furthermore, the e-receipt is obtained by the consumer without registering personal information or contact information with the merchant, which preserves the anonymity of the consumer with respect to the merchant.

Embodiments of the invention are directed to systems, methods, and computer program products for onboarding digital content to a platform designed specifically for seamless creation and user-friendly management of non-fungible tokens. The invention allows for users with zero knowledge of decentralized protocols to leverage the benefits of such technologies by providing a system for uploading existing digital content, automating the creation of one or more non-fungible tokens, managing permissioned access to the non-fungible tokens, and facilitating the ownership transfer of the non-fungible tokens.

Systems and techniques to apply NFT content to immersive environment generation within an NFT platform are illustrated. One embodiment includes a method for rendering content. The method receives, from one or more sensory instruments, sensory input. The method processes the sensory input into a background source. The method receives a non-fungible token (NFT), wherein the NFT includes one or more character modeling elements. The method processes the one or more character modeling elements from the NFT into a character source. The method produces an immersive environment including features from the background source and features from the character source.

A second blockchain system receives a first consensus message from a first blockchain system, the first blockchain system includes first nodes that provide services to at least a first account, and the second blockchain system includes second nodes that provide services to at least a second account. The first consensus message indicates a first plurality of the first nodes reaches a consensus for transferring a resource from the first account to the second account. The second blockchain system transfers the resource in the task to the second account. The transferring includes that a node in the second nodes adds the resource to the second account and generates a fourth block that records a completion of a transfer event. A second consensus message is transmitted from the second blockchain system to the first blockchain system in response to a second plurality of the second nodes completing the transfer event.

A system is provided for netting obligations between entities of a cycle of obligations. Each obligation specifying a quantity of an item that a from-entity of the cycle is obligated to provide to a to-entity of the cycle. For each entity, the system determines whether the sum of its inventory of the item and the quantity of the obligation on which it is a to-entity is sufficient to satisfy the obligation on which it is a from-entity. When sufficient, the system identifies one or more netting transactions to settle the obligations of the cycle. The system then directs the execution of the netting transactions and settlement transactions to effect and record the settling of the obligations.

A method for distributing data to a computing device using device level authentication includes: receiving a single use key from a payment institution, the single use key encrypted by the payment institution using a first encryption, a server public key, and device data; wrapping a device public key using the server public key; electronically transmitting at least the device data, the wrapped device public key, and the single use key to a server; receiving the single use key encrypted using a second encryption from the server, the second encryption using the device public key to encrypt the single use key; decrypting the single use key encrypted with the second encryption using a device private key; and electronically transmitting the decrypted single use key and payment credentials to a point of sale device.

At an authorization server, a shared secret electronic key may be shared with a second computer. A selection to use a system to complete a transaction may be received from a first computing device. An image may be communicated to the first computing device. A digital representation entered by the user representing the image and a PIN based on the copy of the shared electronic key may be received from the second computing device. The system and method may determine if the digital representation entered by the user on the second computing device matches the image communicated to the first computing device. The system and method may determine if the PIN based on the copy of the shared electronic key from the second computing device is as expected. In response to determining the digital representation entered by the user matches the image and the PIN the second computing device is as expected, the user may be authorized.

A computer-implemented method for anonymizing online transaction details may include performing a process to generate an identifier (ID) and reference address for a user, and receiving a request for transaction processing from an e-commerce server. The request may include first data including: information associated with a purchase of a product to be delivered to the user; the identifier; and the reference address. The method may further include: in response to the request, determining whether the ID and reference address are included in the request, and if so, obtaining the accurate address and shipping rate rules; applying, based on the first data and the accurate address, the shipping rate rules to determine accurate shipping rate cost information associated with delivering the product to the accurate address; performing an anonymizing process on the accurate information to obtain anonymous shipping rate information, and transmitting the anonymous shipping rate information to the e-commerce server.

The invention resides in a blockchain-implemented method of operating a system having a device, the method comprising: using, processing and/or generating a blockchain transaction (MTx) having: one or more token-related outputs (T-UTXO), each of which represents a respective token (T) issued by a Token Issuer (TI) and specifies a) at least one of the operation, status and data that determines the configuration of the device; b) a quantity of token-related cryptocurrency (TRC) associated with the respective token (T). The operation, status and data that determines the configuration and/or status of the device can be determined from instructions on the output of a respective token's blockchain transaction. Generally, assets or resources can be tracked and/or managed using one or more blockchain transactions in which token-related outputs, representing tokens, function to determine the status of an asset.
