Problems solved by technology

[0002] With the current environment of using bank cards and cardholders’ habit of using cards becoming more and more mature, emerging payment methods such as online payment and mobile payment have emerged one after another. While these emerging payment methods bring convenience to cardholders, they also make The card-using environment has become more complex, and security issues such as fraud and counterfeiting have created new breeding grounds. The security risks faced by sensitive information input and transmission during user transactions are worrying.

[0003] Ordinary bank smart chip cards only include logic processing chips, data storage chips and simple I / O (Input / Output, input / output) communication ports, and the I / O ports only have two types of conductive sheets and capacitor coils, so During the online payment transaction, the card can only passively obtain a small amount of transaction sensitive information such as the transaction amount through external terminal equipment, and the input, output, confirmation, encryption, and data integrity authentication of sensitive information need to be directly communicated with the card. The customer's transaction terminal equipment is completed (customer's PC (personal computer, personal computer) and mobile terminal equipment), this type of equipment usually runs on an open software and hardware platform, and has poor protection against illegal means such as data interception, tampering, and counterfeiting , IC (Integrated Circuit, integrated circuit) security function provided by the card itself has not been fully utilized
