INFORMATION TERMINAL DEVICE, METHOD TO PROTECT HANDWRITTEN INFORMATION, AND DOCUMENT MANAGEMENT SYSTEM

摘要

In order to prevent confidential information inputted in handwriting from being divulged, an information terminal device has an input section to input information in handwriting on an entry screen which displays a designated form of a document, a judgment section judging whether or not an inputted positional coordinate is in a particular field of the designated form, and a control section controlling the entire information terminal device to display the information inputted in handwriting within the particular field in the particular field while the coordinate of the information inputted in handwriting is within the particular field, and to make the information inputted in handwriting displayed in the particular field unreadable when the coordinate of the information inputted in handwriting is outside of the particular field or when a predetermined time frame has elapsed since the last stroke in the particular field.
