Abstract
Description
図2は、入力装置上面の外観構成を示す。ユーザは左手で左側把持部78bを把持し、右手で右側把持部78aを把持して、入力装置6を操作する。入力装置6の筐体上面には、方向キー71、アナログスティック77a、77bと、4種の操作ボタン76が設けられている。4種のボタン72~75には、それぞれを区別するために、異なる色で異なる図形が記されており、○ボタン72には赤色の丸、×ボタン73には青色のバツ、□ボタン74には紫色の四角形、△ボタン75には緑色の三角形が記されている。
ログイン処理1は、ユーザがユーザ選択画面において、入力装置6を操作して自分のアイコンを選択し、ログイン用パスコードを入力することで、情報処理装置10がユーザ認証を行い、ユーザをログインさせる処理である。
<ログイン処理2>
ログイン処理2は、ユーザが指紋センサ79aに指をあてると、入力装置6が指紋照合によるユーザ認証を行い、情報処理装置10側ではユーザ識別情報を用いたユーザ認証を行って、ユーザをログインさせる処理である。
指紋認証ログインのために、ユーザは、自分の指紋の認証用データを入力装置6に登録する。制御部88は、指紋を登録するユーザを特定した状態のもとで、認証用データの登録処理を実施する。ここでは、情報処理装置10の登録ユーザであるユーザAが、指紋を登録する。ユーザAが指を指紋センサ79aに置くと、指紋センサ79aはユーザAの指紋情報を受け付ける。指紋センサ79aは指紋情報として、指紋画像を取得してよい。指紋認証部84は、指紋センサ79aが受け付けた指紋情報から、認証用データを生成する。制御部88は、認証用データを、指IDに関連づけて認証用データ保持部85に保持させる。ここで指IDは、認証用データ登録の順番を示す。したがって最初に登録された認証用データには、指ID「1」が、2番目に登録された認証用データには、指ID「2」が割り当てられる。
<ログイン処理1>
ユーザAが入力装置6の所定のボタン(たとえば機能ボタン80)を押下すると、通信部90が、その押下情報を情報処理装置10に送信する。情報処理装置10において、通信部102が押下情報を接続要求として受け付けて、入力装置6の通信部90と情報処理装置10の通信部102とが接続する。なお情報処理装置10のメイン電源がオフとなっている場合には、機能ボタン80の押下情報により情報処理装置10のメイン電源がオンとなった後、通信部102が通信部90と接続する。機能ボタン80の押下情報はログイン処理部112に伝達され、ログイン処理部112は、この押下情報を、ユーザからのログイン要求として受け付ける。
図6(a)のユーザ選択画面の上段にテキスト表示されているように、指紋登録しているユーザAは、入力装置6の指紋センサ79aに指を置くだけで、ログインできる。
図7は、ログイン処理2のシーケンスの一例を示す。図6(a)に示すユーザ選択画面の表示中、指紋センサ79aは、指紋情報を受け付け可能な状態を維持する(S10のN)。ユーザAが指紋センサ79aに指を配置すると、指紋センサ79aは、ユーザAの指紋情報を受け付け(S10のY)、指紋認証部84に供給する。指紋認証部84は、指紋センサ79aが受け付けた指紋情報と、認証用データ保持部85に保持された1以上の登録ユーザの認証用データを照合して、ユーザAが登録ユーザであることを認証する(S12のY)。なお仮にユーザAが指紋登録をしていなければ、指紋認証部84は、ユーザ認証に失敗する(S12のN)。
