ELECTRONIC INFORMATION TERMINAL, METHOD FOR PROTECTING HANDWRITTEN INFORMATION, AND DOCUMENT MANAGEMENT SYSTEM

摘要

PROBLEM TO BE SOLVED: To prevent leakage of confidential information.;SOLUTION: A detection unit 102 detects an input coordinate position where a handwriting input is made by an input unit 101 on a document image in a predetermined format. When a specific area determination unit 104 determines that the coordinate position of the handwriting input is within a specific coordinate area (a confidential information area), an image conversion unit converts a trajectory of acquired coordinate data into image data, and displays it on a display unit 110. When it is determined that a next input coordinate position detected by the detection unit 102 is not within the specific coordinate area, the image data previously displayed on the display unit 110 is made unidentifiable.;COPYRIGHT: (C)2014,JPO&INPIT
