Privacy-Preserving Cryptographic Solutions for Financial Transactions

Abstract

: With the increasing digitization of financial transactions, ensuring privacy and security has become a critical challenge. Traditional cryptographic techniques such as RSA and AES provide strong security guarantees but do not always protect user privacy. Privacy-preserving cryptographic solutions, including zero-knowledge proofs, homomorphic encryption, and secure multi-party computation, offer enhanced privacy for financial transactions while maintaining security and efficiency. This paper explores modern cryptographic techniques that preserve financial privacy, their advantages, implementation challenges, and future research directions
