Claim Text:
1. An information processing device, comprising: a touch panel; at least one processor; and at least one storage device that stores a plurality of instructions, which when executed by the at least one processor, causes the at least one processor to operate to: obtain a result of detection by the touch panel detecting a plurality of positions touched by a user; refer to authentication data stored in the at least one storage device, the authentication data indicating a plurality of types of operation which the user perform in a predetermined order via the touch panel, and a number of fingers, as to each one of the plurality of types of operation, with which the user touch the touch panel when performing an operation corresponding to the one of the plurality of types of operation; execute authentication processing by determining, based on a result of detection by the touch panel and the authentication data, whether or not an operation corresponding to each of the plurality of types of operation has been performed in the predetermined order by touching the touch panel with a number of fingers set for each of the plurality of types of operation, and unlock the information processing device based on the determination of a successful authentication, wherein the authentication data further indicates, as to at least one of the plurality of types of operation, a direction in which the user moves one or more fingers touching the touch panel when performing an operation corresponding to each of the at least one of the plurality of types of operation, the at least one processor executes the authentication processing, when determining whether or not an operation corresponding to a type of operation for which the direction is set has been performed, by determining whether or not the operation corresponding to the type of operation has been performed by touching the touch panel with a number of fingers set for the type of operation and moving the one or more fingers touching the touch panel in a direction corresponding to the direction set for the type of operation, and the authentication data indicates a direction in which the user moves a plurality of fingers touching the touch panel when performing an operation corresponding to the type of operation with a relative direction with respect to a direction in which the plurality of fingers touching the touch panel are aligned.
