Title: Cryptographic method and system for secure extraction of data from a blockchain
Inventor: CRAIG STEVEN WRIGHT
IPC: H04L9/30
Filed: 2017-02-21
Abstract: The invention relates generally to cryptographic techniques for secure processing, transmission and exchange of data. It also relates to peer-to-peer distributed ledgers such as (but not limited to) the Bitcoin blockchain. In particular, it relates to control solutions for identifying, protecting, extracting, transmitting and updating data in a cryptographically controlled and secure manner. It also relates to system inter- operability and the ability to communicate data between different and distinct computing systems. The invention provides a computer implemented method (and corresponding systems) comprising the steps of identifying a set of first structure public keys comprising at least one public root key associated with a first structure of interest of an entity and one or more associated public sub-keys; deriving a deterministic association between the at least one public root key and the one or more associated public sub-keys; and extracting data from a plurality of transactions (TXs) from a blockchain. The data comprises data indicative of a blockchain transaction (Tx) between the first structure and at least one further structure; and a first structure public key associated with the first structure. The first structure public key is part of a cryptographic public/private key. The method includes the step of generating an output for the first structure of interest by matching at least part of the set of first structure public keys to the extracted transaction data using the deterministic association. The one or more public sub-keys is generated or determined using Elliptic Curve Cryptography (ECC) and a deterministic key (DK) that is based on a cryptographic hash of a message (M). The one or more public sub-keys is determined based on a scalar addition of an associated public parent key and the scalar multiplication of a deterministic key (DK) and a generator (G).

Abstract: A computer-implemented method, a computer program product, and a computer system for misinformative content mitigation. A computer receives from a social network system a request for curated content, where the curated content is related to misinformative content that has been identified by the social network system. The computer sends to a system of a payed curated content producer a request for making the curated content public. In response to that the system of the payed curated content producer accepts the request for making the curated content public, the computer provides to the social network system a link to the curated content on the system of the payed curated content producer. On the social network system, the misinformative content is flagged and the link to the curated content is presented aside the misinformative content.
