FREE STREAM MEDIA CORP D/B/A SAMBA TV [US]

US_2020058019_A1

Resumen de: WO2020037139A1

Approaches presented herein provide for the management of viewership data, including contractual terms and transaction history, through immutable distributed ledgers, such as blockchain. Temporary identifiers can be used to store viewership data for a viewer to one of these public, distributed ledgers. A physical device identifier is associated with a media device. An identity manager generates and rotates temporary public identifiers that are mapped to the physical identifier of the device. Viewership data from the device and the related temporary identifiers are stored on the public distributed ledger. The identity manager receives a contract to provide viewership data of media device over a particular period. The identity manager supplies the temporary identifiers of the media device over the period specified. Upon fulfilment of the contract, the identity manager rotates the temporary identifier associated with physical device to ensure that prior temporary identifiers are no longer mapped to the same physical device identifier. The terms of the contract and subsequent viewership data are stored on the distributed ledger.

Decentralized Data Marketplace

NºPublicación: US2020058023A1 20/02/2020

Solicitante:

GRANDATA INC [US]

Resumen de: US2020058023A1

A blockchain-based, decentralized data marketplace is described. The marketplace allows data sellers to sell their data to data buyers in exchange for payments in tokens. The marketplace allows for securely and anonymously selling data in a trusted environment that is also fair to all participants and provides data sellers with the ability to control and monetize their own data (e.g., personal data). A notary with access to “ground truth” data can validate data that is being offered in the marketplace to ensure that it is not falsified or fabricated before it is purchased by a data buyer. The marketplace implements blockchain-based smart contracts that work together, and with cryptographic protocols, to achieve an efficient, decentralized data marketplace where data sellers and data buyers transact directly with one another while remaining anonymous, if desired.

BLOCKCHAIN FOR THE COMMON GOOD: DIGITAL CURRENCY FOR CITIZEN PHILANTHROPY AND SOCIAL ENTREPRENEURSHIP

NºPublicación: US2020058055A1 20/02/2020

Solicitante:

UNIV GEORGE WASHINGTON [US]

Resumen de: US2020058055A1

A distributed ledger application for the world of citizen philanthropy and social entrepreneurship, with stakeholder incentives designed to increase social good through accountability, transparency, and flexibility. In this system, called Directed Cash, individual donors specify conditions (the “Directed” part) attached to their donation or investment (“Cash”), that are then efficiently paired with interested recipients or aggregators of recipients (charities, social entrepreneurs) using distributed consensus so that the intent and pairing are open while maintaining donor anonymity. Furthermore, Directed Cash flows both ways to promote accountability and transparency: after receipt, a validation flows backwards to return to the donor so that the donor receives a report of how their donation was spent. While some elements of the system borrow from existing cryptocurrency and blockchain technologies, we propose alternative incentives for distributed consensus that are better aligned with the application and promote social good through the stakeholders. This invention is for a system design to achieve these goals, a primary feature of which is a simple SQL-like language to enable specifying conditions, pairing, aggregation and publicly-verifiable reporting.

TIME-BOUNDED ACTIVITY CHAINS WITH MULTIPLE AUTHENTICATED AGENT PARTICIPATION BOUND BY DISTRIBUTED SINGLE-SOURCE-OF-TRUTH NETWORKS THAT CAN ENFORCE AUTOMATED VALUE TRANSFER

NºPublicación: US2020058020A1 20/02/2020

Solicitante:

PROBLOCH LLC [US]

Resumen de: US2020058020A1

The disclosure relates to executing time bound activity chains using a baseline blockchain that encodes milestones and a realized blockchain that tracks activity relating to the milestones encoded on the baseline blockchain. Each project managed by the system may be scheduled using its own baseline blockchain, which stores time-bounded activity chains that encode milestones for that project. The realized blockchain stores performance related activity that validates and stores information indicating performance of actions related to milestones and automated transfer of value through the use of smart contracts. Each block of the realized blockchain not only references a prior block of the realized blockchain but also a corresponding baseline block, which encodes a milestone, in the baseline blockchain. Thus activity relating to progress toward a milestone may be recorded on a realized block, which refers back to a baseline block that specifies the milestone.

BLOCKCHAIN-BASED COMMODITY ANTI-COUNTERFEITING CODE GENERATION SYSTEM

NºPublicación: WO2020034623A1 20/02/2020

Solicitante:

QI AIMIN [CN]

Resumen de: WO2020034623A1

The present invention provides a blockchain-based commodity anti-counterfeiting code generation system, which belongs to the field of anti-counterfeiting codes. In the present invention, by means of a duplex anti-counterfeiting technique, a layer of public information and a layer of anti-counterfeiting verification information are generated, wherein the anti-counterfeiting verification information becomes invalid once verified, so that an anti-counterfeiting code cannot be copied, thereby achieving a real anti-counterfeiting effect. In addition, since the anti-counterfeiting code cannot be copied, a verification code contains specific information of a commodity, making anti-counterfeiting more secure. Verification information is verified via a public blockchain, and during the first verification, the verification process needs to be photographed and stored, and photographing information is returned to the public blockchain and is taken as a return result of subsequent verification, so that the anti-counterfeiting code cannot be copied, thereby achieving a real anti-counterfeiting effect. Furthermore, a chaos formula is used to generate authenticity verification information, so that duplicate authenticity verification information cannot be generated.
