Credit card dynamic verification password refers to the verification password that needs to be entered when using a credit card. For daily personal use, it is often sent to the mobile phone number reserved by the bank in the form of mobile phone text messages.
Dynamic passwords generate an unpredictable random number combination based on a special algorithm. Each password can only be used once. The mainstream generation forms include mobile phone text messages, hardware tokens, and mobile phone tokens.
The advantage of dynamic passwords is that they are easy to use and are platform-independent. They can be used smoothly through computers, mobile phones, and IPADs. They are widely used in online banking, online games, and telecommunications fields.

Features of the dynamic password system:
1. No need to remember
Forgetting passwords is a headache for many people. With the popularity of network applications, more and more passwords need to be remembered by people. Dynamic password cards eliminate the need for users to remember multiple passwords.
2. Double insurance
DKEY dynamic password authentication system adopts a two-factor authentication mechanism. Even if the user loses the dynamic password card and account at the same time, no loss will be caused.
3. Get informed quickly
Under the traditional authentication mechanism, user passwords are often lost or stolen without their knowledge. The harm is only noticed after it occurs, and the only way to remedy the situation is to make up for it. Once the dynamic password token is lost, the user will immediately discover it and report the loss in time to prevent problems before they occur.
4. Both internal and external intruders
Among the intruders in information systems, internal intruders account for more than 80%. As far as e-commerce sites are concerned, the weakest link in information security is internal defense. For example, network administrators can also obtain user confidential information through normal authorization, which is undoubtedly a threat to user information security.
The dynamic password authentication system completely leaves key generation and management to the system automatically, which minimizes human factors, effectively prevents insiders from committing crimes, and makes the system security as strong as internal and external. .
5. Simple and easy
IC card authentication, CA authentication, and fingerprint authentication all require the cooperation of special terminal authentication equipment, and the scope of application is greatly limited. Currently, USKKEY is more commonly used. , also needs to be plugged into a computer, and currently cannot be used with phone transactions that have a large number of users. Dynamic password tokens can be implemented on any device that can input decimal numbers and are easy to use.
The system is relatively independent, has a simple interface, and is easy to interface with the existing e-commerce site authentication system. It uses a dedicated dynamic password authentication server for authentication to ensure the integrity of the existing application system and protect system resources.
