Device for securing contents of a web page

A web page providing device comprising:

• at least one memory operable to store program code;
• and
• at least one processor operable to read said program code and operate according to said program code, said program code including:
• receiving code configured to cause at least one of said at least one processor to receive a request for a web page from a terminal, wherein the web page is an order page for inputting information necessary for purchasing an item;
• and
• transmitting code configured to cause at least one of said at least one processor to transmit to the terminal the web page, wherein the terminal executes a script code that causes the terminal to:
• measure an elapsed time from a most recent operation on the terminal by a user of the terminal, wherein the most recent operation is the last operation of the user in time,
• determine whether the elapsed time exceeds a predetermined time,
• when it is determined that the elapsed time exceeds the predetermined time, change a display mode of the web page from a first display mode to a second display mode in which visibility of at least part of the web page is reduced;
• restore the display mode of the web page to the first display mode in a case where a reset operation is performed by the user of the terminal when the display mode of the web page is the second display mode;
• and
• the at least one processor is further configured to determine whether the item is out of stock, and when it is determined that the item is out of stock and the display mode of the order page is the second display mode, the display mode of the order page is restored to the first display mode without requesting input of a password in an authentication screen.

A non-transitory computer-readable medium storing a web page providing program causing a computer to:

• receive a request for a web page from a terminal, wherein the web page is an order page for inputting information necessary for purchasing an item;
• and
• transmit to the terminal the web page, wherein the terminal executes a script code that causes the terminal to:
• measure an elapsed time from a most recent operation on the terminal by a user of the terminal, wherein the most recent operation is the last operation of the user in time,
• determine whether the elapsed time exceeds a predetermined time;
• when it is determined that the elapsed time exceeds the predetermined time, change a display mode of the web page from a first display mode to a second display mode in which visibility of at least part of the web page is reduced;
• and
• restoring the display mode of the web page to the first display mode in a case where a reset operation is performed by the user of the terminal when the display mode of the web page is the second display mode;
• determine whether the item is out of stock;
• and
• when it is determined that the item is out of stock and the display mode of the order page is the second display mode, the display mode of the order page is restored to the first display mode without requesting input of a password in an authentication screen.
