Display system, display method, display terminal and non-transitory computer-readable recording medium stored with display program

A display method for displaying a document using a first display terminal and a second display terminal, comprising the steps of:

• displaying non-confidential information on a first display of said first display terminal which does not display confidential information that a first user is not allowed to browse, but displays the non-confidential information that the first user is allowed to browse with regard to the document;
• executing, performed by a first hardware processor of said first display terminal, a process of determining whether an image and/or an object is the confidential information or not, based on determining whether the image and/or the object is a predetermined region attribute or not, and transmitting the image and/or the object which has been determined to be confidential information to said second display terminal as the confidential information;
• executing, performed by a second hardware processor of said second display terminal, a process of receiving the confidential information, and acquiring the non-confidential information displayed on said first display;
• and
• displaying the received confidential information on a second display of said second display terminal which does not allow the first user to browse but allows a second user different from the first user to browse,
• wherein, in said step of displaying the received confidential information on the second display, the received confidential information is displayed so that the received confidential information is visually recognized by the second user in a state of being aligned with the non-confidential information displayed on said first display based on the acquired non-confidential information, the second display is an optical transmission type or a video transmission type, and displays an image synthesized by aligning the acquired non-confidential information with the confidential information, and
• said region attribute of the image and/or the object designates a character, a given character, a graphic, a photograph, color, an underline, or a combination of at least two thereof.

A display terminal, which is applied to a display system comprising a first display terminal and a second display terminal, for displaying a document as the first display terminal, the display terminal comprising:

• a first display which does not display confidential information that a first user is not allowed to browse, but displays non-confidential information that the first user is allowed to browse with regard to the document;
• and
• a first hardware processor which executes a process of determining whether an image and/or an object is the confidential information or not, based on determining whether the image and/or the object is a predetermined region attribute or not, and transmitting the image and/or the object which has been determined to be confidential information to a terminal device, which is said second display terminal, as the confidential information,
• wherein said terminal device comprises:
• a second display which does not allow the first user to browse, but allows a second user who is different from the first user to browse;
• and
• a second hardware processor which executes a process of receiving the confidential information, and acquiring the non-confidential information displayed on said first display, and
• wherein said second display, based on the acquired non-confidential information, displays the received confidential information so that the received confidential information is visually recognized by the second user in a state of being aligned with the non-confidential information displayed on said first display, said second display is an optical transmission type or a video transmission type, and displays an image synthesized by aligning the acquired non-confidential information with the confidential information, and
• said region attribute of the image and/or the object designates a character, a given character, a graphic, a photograph, color, an underline, or a combination of at least two thereof.

A non-transitory computer-readable recording medium stored with a display program of a display terminal, which is applied to a display system comprising a first display terminal and a second display terminal, for displaying a document as the first display terminal, said display program causing said display terminal to execute a process,

• wherein said process comprising the procedures of:
• (A) determining whether an image and/or an object is the confidential information or not, by a first hardware processor of said display terminal, based on determining whether the image and/or the object is a predetermined region attribute or not;
• (B) displaying, with regard to the document, the image and/or the object determined not to be confidential information, by said first hardware processor, on a first display of said display terminal which does not display the confidential information that a first user is not allowed to browse but displays the non-confidential information that the first user is allowed to browse as the non-confidential information;
• and
• (C) transmitting the image and/or the object which is determined to be confidential information to a terminal device which is the second display terminal by said first hardware processor of the display terminal as confidential information,
• wherein said terminal device comprises
• a second display which does not allow the first user to browse, but allows a second user different from the first user to browse, and
• a second hardware processor which executes a process of receiving the confidential information, and acquiring the non-confidential information displayed on said first display, and
• wherein said second display, based on the acquired non-confidential information, displays the received confidential information so that the received confidential information is visually recognized by the second user in a state of being aligned with the non-confidential information displayed on said first display, said second display is an optical transmission type or a video transmission type, and displays an image synthesized by aligning the acquired non-confidential information with the confidential information, and
• said region attribute of the image and/or the object designates a character, a given character, a graphic, a photograph, color, an underline, or a combination of at least two thereof.
