Abstract

A method and a system for managing account transactions aim to effectively prevent account information from being compromised. The system generates a dynamic account number corresponding to a true account number of an account of a user and sends the dynamic account number to the user. The system stores the corresponding relationship between the true account number and the dynamic account number. The system conducts an account transaction requested by the user according to the dynamic account number supplied by the user and the corresponding relationship. The account can be a bank account, and the dynamic account number may be valid for a one-time use or set to expire after a certain period of time or a certain number of uses. The method and the system can make account transactions more reliable and safer, and effectively prevent user account information from malicious access.

Claims

1. An account transaction management system, comprising:

a dynamic account number generating unit used for generating a dynamic account number corresponding to a true account number of an account of a user;

a dynamic account number sending unit used for sending the dynamic account number to the user or printing out the dynamic account number;

a user account information database used for storing a corresponding relationship between the true account number and the dynamic account number; and

a dynamic account number processing unit used for processing an account transaction according to the dynamic account number provided by the user and the corresponding relationship between the true account number and the dynamic account number.

2. The system as recited in claim 1, further comprising:

a dynamic account number maintenance unit used for deleting or invalidating the stored corresponding relationship between the dynamic account number and the true account number in the user account information database after the dynamic account number has been used for once or a certain number of times.

3. The system as recited in claim 1, wherein the dynamic account number sending unit sends the dynamic account number to a mobile phone of the user.

4. The system as recited in claim 1, wherein the dynamic account number sending unit sends the dynamic account number to the user through one or a combination of communication methods including text messaging, e-mail, regular mail, voice messaging, and personal contact.

5. The system as recited in claim 1, wherein the account of the user is a bank account.

6. The system as recited in claim 1, wherein the dynamic account number generating unit generates the dynamic account number in response to a user request.

7. The system as recited in claim 1, wherein the dynamic account number generating unit generates a plurality of dynamic account numbers, and the dynamic account number sending unit sends the plurality of dynamic account numbers to the user together.

8. The system as recited in claim 1, wherein the dynamic account number has a set expiration date.

9. The system as recited in claim 1, wherein the account number processing unit comprises:

a receiving unit used for receiving the dynamic account number from the user;

a conversion unit used for converting the dynamic account number received by the receiving unit into the corresponding true account number based upon the corresponding relationship stored in the user account information database; and

an execution unit used for executing the account transaction using the true account number obtained by the conversion unit.

10. The system as recited in claim 1, wherein the dynamic account number processing unit is further adapted for receiving a password from the user and verifying the password against the account associated with the true account number before performing the account transaction.

11. The system as recited in claim 1, wherein the account number processing unit receives the dynamic account number from the user directly.

12. An account transaction management method, comprising:

generating a dynamic account number corresponding to a true account number of an account of a user;

sending the dynamic account number to the user;

storing a corresponding relationship between the true account number and the dynamic account number; and

conducting an account transaction according to the dynamic account number supplied by the user and the corresponding relationship.

13. The account transaction management method as recited in claim 12, wherein, after the dynamic account number has been used for once or a certain number of times, the corresponding relationship of the dynamic account number and the true account number is deleted or invalidated.

14. The account transaction management method as recited in claim 12, wherein conducting an account transaction according to the dynamic account number supplied by the user and the corresponding relationship comprises:

converting the dynamic account number provided by the user into the true account number according to the corresponding relationship; and

conducting the account transaction for the user if a password provided by the user match that of the account.

15. The account transaction management method as recited in claim 12, wherein the dynamic account number is sent to the user through text messaging.

16. The account transaction management method as recited in claim 12, wherein the dynamic account number sending unit sends the dynamic account number to the user through one or a combination of communication methods including text messaging, e-mail, regular mail, voice messaging, and personal contact.

17. The account transaction management method as recited in claim 12, wherein the account is a bank account.

18. The account transaction management method as recited in claim 12, wherein the account is a bank account, and the account transaction comprises a fund withdrawal.

19. One or more computer-readable media storing computer-executable instructions that, when executed, perform acts comprising:

generating a dynamic account number corresponding to a true account number of an account of a user;

sending the dynamic account number to the user;

storing a corresponding relationship between the true account number and the dynamic account number; and

conducting an account transaction according to the dynamic account number supplied by the user and the corresponding relationship.

20. The one or more computer-readable media as recited in claim 19, wherein the account is a bank account, and conducting the account transaction requires the user to enter a password of the account.
