Summary: | PROBLEM TO BE SOLVED: To reduce a user's work burden in user identification and prevent fraudulent user identification due to a peep by another person.SOLUTION: A portable terminal 10 includes: a touch panel 12b that accepts touch input by an object of the touch input; and a CPU 11 that acquires, according to information on the touch input to the touch panel 12b, at least one of distance between a plurality of taps on a plane of the touch panel 12b, a time interval between the plurality of taps, and distance of the object of the touch input from the touch panel 12b, as feature information of the touch input, determines whether there is a user who has a distribution pattern of the acquired feature information identical with one of the distribution patterns of the feature information stored in a flash memory 17, and when there is an applicable user, identifies the user.SELECTED DRAWING: Figure 1
【課題】ユーザ識別において、ユーザの作業負担を軽減し、他人の覗き見による不正なユーザの識別を防ぐことである。【解決手段】携帯端末10は、タッチ入力の物体によるタッチ入力を受け付けるタッチパネル12bと、タッチパネル12bへのタッチ入力の情報に応じて、タッチパネル12bの平面上の複数のタップのタップ間距離と、複数のタップのタップ間時間間隔と、タッチパネル12bからのタッチ入力の物体の距離と、の少なくとも一つをタッチ入力の特徴情報として取得し、取得された特徴情報の分布パターンが、フラッシュメモリ17に記憶されている特徴情報の分布パターンと同じであるユーザがあるか否かを判別し、該当するユーザがある場合に、当該ユーザを識別するCPU11と、を備える。【選択図】 図1 |
