Title:
ELECTRONIC DEVICE, IMAGE FORMATION APPARATUS, AND LOG-IN AUTHENTICATION METHOD
Document Type and Number:
WIPO Patent Application WO/2022/030303
Kind Code:
A1
Abstract:
Every time an operation unit (13) receives an input of one character in a password, a display control unit (92) retrieves one image randomly from an image storage device (7), and displays the image as a background image on a display unit (14). When a touch panel (15) detects a touch operation, an acquisition unit (93) acquires a file name of the image displayed on the display unit (4), and a touch position from the touch panel, and stores the file name and the touch position in an acquired information storage unit (94). When the touch panel (15) receives a touch on a log-in button, a log-in authentication unit (95) reads from a security information storage unit (71) a password, a security image, and a security touch range stored in association with a user ID to verify the input password, a selected security image, and content read from a security touch position. If matched, the log-in authentication unit (95) allows log-in of the user.
