Three new Blockchain Patents Issued to Nchain Group
Nchain, a blockchain technology, and development firm is issued with three new patents by the European Patent Office.
The company’s latest intellectual property invented by Nchain’s chief scientist, Dr. Craig Wright, cover “digital rights management using blockchain.”
Digital rights management allows creators of digital content the ability to ensure that they are paid for their work. Nchain asserts that the three new patents issued by the European Patent Office will help bolster digital rights management.
“These third, fourth and fifth patent grants by the European Patent Office marks demonstrate the value in Nchain’s program for blockchain innovation,” explains the Nchain Group CEO Jimmy Nguyen.
Digital Rights Management Using Blockchain
The three patents acquired by Nchain and invented by Dr. Craig Wright include:
EP3295349 “A method and system for verifying the integrity of a digital asset using a distributed hash table and a peer-to-peer distributed ledger”. This invention uses a standard Bitcoin Cash transaction that includes additional metadata to reference an entry within an external Distributed Hash Table (DHT) where signatures of the digital asset, plus the signatures on the DHT and the signature on the blockchain transaction itself, must align to demonstrate the integrity of the asset.
EP3295362 “A method and system for verifying ownership of a digital asset using a distributed hash table and a peer-to-peer distributed ledger”. This invention builds on the technique in the first invention above (EP3295349) to add another set of cryptographic operations that allows the current owner of the digital asset to be validated.
EP3295350 “A method and system for verifying ownership of a digital asset using a distributed hash table and a peer-to-peer distributed ledger”. This invention is a logical extension of the technique defined in the second invention above (EP3295362); it allows the computer software to check the rights of the user to execute such software prior to launching that software.
