System and method for using customer information in electronic commerce

A system comprising:

• a separate customer information DB storing a unique number for each customer;
• an integrated customer information DB storing customer information corresponding to the unique number in an integrated manner;
• and
• a management server configured to determine whether to provide the unique number or the customer information when an external terminal requests customer information via a request, to provide the unique number stored in the separate customer information DB when it is determined that the unique number is to be provided, and to provide the customer information from the integrated customer information DB corresponding to the unique number when it is determined that the customer information is to be provided, the management server being further configured to provide access to the separate customer information DB and the integrated customer information DB through different manager accounts, the management server being configured to provide access to the separate customer information DB through a first manager account but prevent access to the separate customer information DB through a second manager account different from the first manager account, the management server being configured to provide access to the integrated customer information DB through the second manager account but prevent access to the integrated customer information DB through the first manager account, and the management server being further configured to change the unique number stored in the separate customer information DB at uniform time intervals.

A method comprising:

• receiving, by a management server, input customer information;
• creating, by the management server, a unique number for a customer corresponding to the customer information;
• storing, by the management server, the created unique number for the customer in a separate customer information DB and separately storing the customer information corresponding to the unique number in an integrated customer information DB;
• providing, by the management server, the unique number stored in the separate customer information DB and providing the customer information from the integrated customer information DB corresponding to the unique number under a security condition when an external terminal requests customer information, the management server providing access to the separate customer information DB and the integrated customer information DB through different manager accounts, the management server providing access to the separate customer information DB through a first manager account but preventing access to the separate customer information DB through a second manager account different from the first manager account, and the management server providing access to the integrated customer information DB through the second manager account but preventing access to the integrated customer information DB through the first manager account;
• and changing, by the management server, the unique number stored in the separate customer information DB at uniform time intervals.

• receiving input customer information;
• creating a unique number for a customer corresponding to the customer information;
• storing the created unique number for the customer in a separate customer information DB and separately storing the customer information corresponding to the unique number in an integrated customer information DB;
• providing the unique number stored in the separate customer information DB and providing the customer information from the integrated customer information DB corresponding to the unique number under a security condition when an external terminal requests customer information, providing access to the separate customer information DB and the integrated customer information DB through different manager accounts, providing access to the separate customer information DB through a first manager account but preventing access to the separate customer information DB through a second manager account different from the first manager account, and providing access to the integrated customer information DB through the second manager account but preventing access to the integrated customer information DB through the first manager account;
• and
