New patents are issued by the USPTO on Tuesdays. Today's Spotlight Patents continue the theme of blockchains (distributed ledgers, smart contracts) and rights management broadly construed. Assigned to Anonos, the first patent addresses techniques for enforcing centralized privacy controls in de-centralized systems. Assigned to Proclus, the second patent addresses techniques for securing a blockchain with proof-of-transactions.
10,572,684, "Systems and methods for enforcing centralized privacy controls in de-centralized systems," assigned to Anonos Inc.
Systems, computer-readable media, and methods for improving both data privacy/anonymity and data value, wherein data related to a data subject can be used and stored, e.g., in a distributed ledger data structure, such as a blockchain, while minimizing re-identification risk by unauthorized parties and enabling data, including quasi-identifiers, related to the data subject to be disclosed to any authorized party by granting access only to the data relevant to that authorized party's purpose, time period, place and/or other criterion via the obfuscation of specific data values, e.g., pursuant to the European Union's General Data Protection Regulation (GDPR) or other similar regulatory schemes. The techniques described herein maintain this level of privacy/anonymity while still satisfying the immutability, auditability, and verification mandated by blockchain and other distributed ledger technologies (DLTs) for the decentralized storage of transactional data. Such systems, media, and methods may be implemented on both classical and quantum computing devices.
10,574,464, "Method and system for securing a blockchain with proof-of-transactions," assigned to Proclus Technologies Limited (CN)
Novel tools and techniques are provided for implementing blockchain transactions, and, more particularly, to methods, systems, and apparatuses for securing a blockchain with proof-of-transactions. In various embodiments, the blockchain system utilizes a proof-of-transactions approach that is based on a multi-player voting system and that is not susceptible to a free-rider problem that affects many other cryptocurrencies. The proof-of-transactions approach allows the cryptocurrency network to divide revenue between the nodes in the peer-to-peer network that provides bandwidth and connectivity and a set of other nodes that solve computational puzzles that safeguard the security of the blockchain system.
