摘要： An authentication device includes an operation panel, a registered handwriting procedure acquiring portion, a long-pressing detecting portion, a handwriting detecting portion, and a handwriting authentication portion. The registered handwriting procedure acquiring portion acquires information of a registered handwriting procedure from a storage portion in which the information of the registered handwriting procedure has been stored, which represents a handwriting procedure including a trajectory of a handwriting operation performed on the operation panel and at least one of a time, a speed, and a number of strokes of the handwriting operation. The handwriting detecting portion detects the handwriting procedure in the handwriting operation performed on the operation panel, during a period in which the long-pressing operation is continuously detected. The handwriting authentication portion determines whether the detected handwriting procedure satisfies a predetermined approximation condition with respect to the acquired registered handwriting procedure, thereby determining whether authentication has succeeded or failed.
