Abstract: Personal information protection is an important proposition in the information era. The security of bank card account information is of vital interest to banks, payment institutions, merchants and cardholders. The protection methods for payment information security commonly used in the past reduce the occurrence of information leakage and transaction fraud to a certain extent. In order to cope with the increasingly severe cyberspace security situation, the payment information protection scheme based on payment tokenization technology fundamentally solves the problem of payment information leakage, and provides convenient and safe payment experience for cardholders, issuers, acquirers and other payment industry parties.

Key words: information leakage, electronic payment information security, payment tokenization, personal information protection, token, bank card number
