Authentication of Financial Wallet System and Data Protection using BlockChain

Abstract

In a BlockChain environment, during validation process or address lookup user personal information may be disclosed or hacked. To prevent this loophole, a Financial Wallet system with authentication and data protection is implemented. In this system, to avoid the disclosure of personal data and to limit the third party intermediaries a BlockChain with Zero knowledge proof is incorporated. To this implementation AES cryptography method is used to secure data. To make it more confidential NFC cards are used to authenticate user instead of passwords.
