Publication number: 20240323306Abstract: An image processing apparatus for performing masking on text-containing data includes a memory storing a program and a processor which executes the program to perform a process. The process includes receiving a selection of attributes for text strings as masking targets and displaying text strings which are identified through analysis and which correspond to the selected attributes and also displaying a preview with the text strings masked. The preview is displayed in a first area, and the text strings are displayed in a second area with information indicating the text strings are selected as masking targets. In response to receiving in the second area a user operation for deselecting one text string as a masking target, the preview in the first area displays the one text string unmasked.Type: ApplicationFiled: March 22, 2024Publication date: September 26, 2024Inventors: YUKARI YANO, AKIKO ITO
