PROBLEM TO BE SOLVED: To provide an information providing device and its system capable of preventing the loan of authentication information to the others. SOLUTION: A server is provided with a product information table 21, drawing number information table 22 and a customer information table 23. The table 21 is information which can be provided only to specified customers. The table 22 is used on the customer side and stores a drawing number as information to be kept secret to the others except a provider at a customer. When 'user30' registered in the table 23 is authenticated, the drawing number and a product number of a line 22a having the customer ID of 'user30' are extracted from the table 22, a line 24a indicated in a transmission information table 24 is generated by extracting respective items of product standard, a product information URL, remarks of a line 21a applicable to the product number from the table 21 and transmitted by converting it into a form which can be displayed on a browser. Consequently, the loan of the authentication information to the others is prevented since the drawing number desired to be kept secret by the customer is displayed on the browser. |
