According to one or more embodiments, a system that enables a user to easily perceive states of off-chain and on-chain content is provided. Content managed on-chain and content managed off-chain are displayed on one screen. The system includes a terminal apparatus and a server apparatus capable of communicating with a distributed ledger network and provides a service including content. The ownership of the content is recordable in the distributed ledger network. The content is stored in a storage device of the server apparatus or recorded on a distributed ledger in the distributed ledger network. The system acquires information about the stored content, acquires information about the recorded content, and displays on-chain information and off-chain information of the content designated from a user on a content moving screen on the terminal apparatus.

The present image forming apparatus: obtains a job ticket related to printing from an information terminal, regarding electronic data for which an ownership is managed in a transaction of a blockchain network; obtains the electronic data from a management server that manages the electronic data, using information that is included in the obtained job ticket and is related to a transaction for transferring or lending the ownership of the electronic data from the information terminal to the image forming apparatus; generate a transaction that contains history information related to the executed printing, using the obtained electronic data and information related to print settings of the job ticket, execute printing; and using the information related to the transaction.

A data processing method based on a blockchain includes creating a target stream-resource transfer channel for a stream-resource channel creation request in the blockchain based on a stream-resource transfer contract in the blockchain, the stream-resource channel creation request comprising a target object address pair, and the target stream-resource transfer channel providing, for the target object address pair, a function of performing stream-resource transfer based on the stream-resource transfer contract; obtaining a historical stream-resource transfer channel comprising a historical object address pair, the target object address pair and the historical object address pair sharing at least one identical object address; combining the historical stream-resource transfer channel and the target stream-resource transfer channel to obtain an update stream-resource transfer channel, the update stream-resource transfer channel comprising an update object address pair; and performing, according to the update stream-resource transfer channel, stream-resource transfer processing associated with the update object address pair.

Systems and methods for probing channel balances are disclosed herein. In some embodiments, channel balances may be probed by sending transfer commands and receiving proofs of transfer. In some embodiments, a first proof of transfer may be verified using a second proof of transfer.

Management systems for music rights and contract generation are described. The contract generation device includes processing circuitry configured to request and/or receive onboarding information from multiple users, the users being, for example, an artist and/or a company, such as a record label. The processing circuitry is further configured to determine, based on the onboarding information and other data, such as parsed responses to a dynamic chatbot and the users' roles and associations with other parties to the contract, a deal scope for a dynamically generated draft contract for the users. The processing circuitry is further configured to dynamically render the draft contract for the users based on the deal scope. The management system and contract generation devices uses song graph modules for machine learning, processing, recording and negotiating rights.

A user who purchases content can temporarily transfer rights to play the content to another device, provided the device registered to have the rights in nearby.

The present invention tracks provenance (people, place, time, permissions, machine characterization and identification) for an off-chain digital asset, provides data verifiability and enforces least privileged access within a single organization or across multiple organizations via a combination of Blockchain and communication agents to enable data assured operations in a normal operating environment and Logistics Under Attack (LUA) environment. The present invention creates data assurance for a digital asset across networks and within environments as it tracks provenance of the digital asset at rest or in motion allowing a data file to move directly from the originator to a customer at the point of use or point of origin to point of use and all points in between in a prescribed or random flow.

The present disclosure relates to a management system for generating and distributing a cell image-based NFT including a cell image generation unit that generates an image from a collected cell, an NFT issuance unit that converts the cell image into an NFT image and stores and manages the NFT image, and an NFT transaction unit that brokers an online transaction for the issued NFT, and a service providing method thereof, and may assign an asset value to a vital image to meet the demand for owning the image.

A data collection method for machine learning is proposed. The method may include accessing machine learning data stored in a device, and requesting an approval for a use of the machine learning data from an entity which has generated the machine learning data. The method may also include determining whether to transmit the machine learning data to a database for learning or a temporary database based on a result of the approval and a similarity between the machine learning data and previously-transmitted-machine learning data. The previously-transmitted-machine learning data may include a first machine learning data which has previously transmitted to the database for learning and a second machine learning data which has previously transmitted to the temporary database.

An image creation and royalty distribution method that is configured to utilize original artwork captured in digital format wherein the pixels thereof are employed to create new visual artwork. Furthermore, the software of the present invention provides tagging of each of the pixels of the original artwork so as to establish and maintain a record of identity of the creator of each pixel of the original artwork. The software of the present invention creates new visual artwork and subsequent creation thereof will produce a list of creators of original artworks from which pixels were utilized to create the new visual artwork. The method of the present invention facilitates payment to each of the creators of the original artwork from which pixels were utilized in a newly created visual artwork. The tags associated with each pixel of the original artwork are non-fungible tokens, alternative blockchain systems or non-blockchain alternatives.
