China bank credit card related regulations:
1. Authenticate both parties to the transaction to prevent payment fraud. Digital signatures and certificates can be used to authenticate all parties involved in online commerce to prevent payment fraud, to authenticate the validity of the identities of all parties involved in online commerce, and to issue digital certificates to all parties involved through certification institutions or registration institutions to confirm the legitimacy of their identities.
2. Encrypt the information flow. We can use single-key system or double-key system to encrypt and decrypt information, and we can use digital envelope, digital signature and other technologies to enhance the confidentiality and integrity of data transmission and prevent unauthorized third parties from obtaining the true meaning of information.
3. The digital digest algorithm confirms the authenticity of payment electronic information. In order to prevent data from being created, embedded, deleted, tampered and replayed by unauthorized people, and reaching the receiver intact, data hashing technology can be adopted.
4. Ensure the non-repudiation of trading behavior and business. When there is a dispute between the two parties in online transaction, especially the dispute related to payment and settlement, the system can ensure the non-repudiation of related behavior or business. The online payment system must generate or provide sufficient evidence in the transaction process, so as to quickly distinguish right from wrong in disputes, which can be achieved by digital signature and other technologies.
5. Dealing with multilateral payment of online trade business. Payment and settlement involve customers, merchants, banks and other parties. The transmitted purchase information and payment instruction information must also be connected together, because the merchant will only continue the transaction after confirming some payment information, and the bank will only provide payment after confirming payment.
In order to ensure security, merchants cannot read customers' payment instructions, and banks cannot read merchants' purchase information. This multilateral payment relationship can be realized by using the technology provided by the system, such as double digital signature.
6. Improve payment efficiency. The procedures and processes of online payment are not complicated and the payment efficiency is very high.
Therefore, China Bank's credit card application for bill installment authorization failed, which means that the bank card cannot carry out installment business.
