SYSTEM AND METHOD FOR PROVIDING ZERO-KNOWLEDGE RANGE PROOFS - A simplified explanation of the abstract

This abstract first appeared for US patent application 20240022416 titled 'SYSTEM AND METHOD FOR PROVIDING ZERO-KNOWLEDGE RANGE PROOFS

Simplified Explanation

The patent application describes a system and method for providing zero-knowledge range proofs for verifiable privacy-preserving queries. Here is a simplified explanation of the abstract:

  • A bilinear group is defined.
  • A query is received from a verifier by a prover.
  • A range proof for the query result is determined using a variation of a bulletproof range proof system.
  • A first inner product for the range proof is generated using the variation of the bulletproof range proof system.
  • A second inner product for the range proof is generated using a trusted inner pairing product proof system.
  • The prover provides elements as the proof to the verifier.

Potential Applications:

  • Privacy-preserving queries in databases: This technology can be used to perform queries on sensitive data without revealing the actual data, ensuring privacy.
  • Cryptocurrency transactions: Zero-knowledge range proofs can be used to verify the validity of transactions without disclosing the exact transaction amounts, enhancing privacy in cryptocurrency transactions.

Problems Solved:

  • Privacy concerns: The technology addresses the problem of maintaining privacy while performing queries on sensitive data or conducting transactions.
  • Verifiability: The range proofs allow verifiers to confirm the validity of the query results or transactions without revealing the underlying data.

Benefits:

  • Privacy preservation: The technology enables the execution of queries or transactions while preserving the privacy of sensitive information.
  • Verifiability: Verifiers can trust the results or transactions without needing to access the actual data, ensuring the integrity of the process.


Original Abstract Submitted

a system and a method for providing zero-knowledge range proofs for verifiable privacy-preserving queries are provided. the method comprises: defining a bilinear group; receiving, by a prover, a query from a verifier; determining a range proof for a result of the query implementing a variation of a bulletproof (bp) range proof system; generating a first inner product for the range proof, implementing the variation of the bp range proof system; generating a second inner product for the range proof, implementing a trusted inner pairing product (tipp) proof system; and providing, by the prover, elements as the proof to the verifier.
