METHODS AND SYSTEMS FOR REGISTERING INFORMATION IN A PERMISSIONED BLOCKCHAIN AND VERIFYING INTEGRITY OF A PAYLOAD - A simplified explanation of the abstract

This abstract first appeared for US patent application 20240015015 titled 'METHODS AND SYSTEMS FOR REGISTERING INFORMATION IN A PERMISSIONED BLOCKCHAIN AND VERIFYING INTEGRITY OF A PAYLOAD

Simplified Explanation

The abstract of this patent application describes a method for registering information in a permissioned blockchain. Here is a simplified explanation of the abstract:

  • The method involves obtaining a hash value of a payload from a controller.
  • A trust bundle is generated, which includes the hash value of the payload and location information of the local client where the hash value was obtained.
  • The trust bundle is sent to an aggregation service and buffered until a predetermined time interval ends.
  • A hash value of the trust bundle sent by the local client is obtained.
  • The hash values of trust bundles aggregated during the first time interval are aggregated into at least one hash tree based on the location.
  • The top hash value of each hash tree corresponding to a service area is added to at least one block in a blockchain.
  • The added blocks are published after a predetermined second time interval ends.

Potential applications of this technology:

  • Supply chain management: The method can be used to register and verify information about products as they move through the supply chain, ensuring transparency and authenticity.
  • Financial transactions: The method can be applied to register and verify financial transactions, providing a secure and immutable record of transactions.
  • Healthcare records: The method can be used to register and verify patient healthcare records, ensuring data integrity and privacy.

Problems solved by this technology:

  • Data integrity: The method ensures the integrity of registered information by using hash values and blockchain technology, preventing tampering or unauthorized modifications.
  • Trust and transparency: By using a permissioned blockchain, the method provides a trusted and transparent system for registering and verifying information, reducing the need for intermediaries.

Benefits of this technology:

  • Security: The method provides a secure way to register and verify information using hash values and blockchain technology, reducing the risk of data breaches or fraud.
  • Efficiency: By aggregating hash values and using predetermined time intervals, the method optimizes the registration and verification process, improving efficiency and scalability.
  • Trust and transparency: The use of a permissioned blockchain ensures trust and transparency in the registered information, enhancing accountability and reducing the need for trust in centralized authorities.


Original Abstract Submitted

an example method for registering information in a permissioned blockchain includes obtaining a hash value of a payload of the controller, generating a trust bundle comprising at least the hash value of the payload and a location information regarding a position of the local client where it obtained the hash value of the payload, sending the trust bundle to an aggregation service, buffering the trust bundle until a predetermined first time interval ends, obtaining a hash value of the trust bundle sent by the local client, aggregating the hash values of trust bundles aggregated during the first time interval into at least one hash tree based on the location, adding the top hash value of each of the at least one hash tree corresponding to the at least one service area to at least one block added to at least one blockchain of a plurality of pre-generated blockchains, wherein each of the at least one blockchain corresponds to the at least one service area of the plurality of predetermined service areas, and publishing the added at least one block of the at least one blockchain after a predetermined second time interval ends. the disclosure further relates to a corresponding system, a method and a system for verifying integrity of a payload, a computer program product and a non-volatile storage medium.
