That is, all the identification data that the duplication unit 205 duplicates and stores by the second duplication method is data that identifies the communication device 30 in the lost state. Therefore, the measurement unit 202 may perform the measurement in the same manner as in the first replication method.

第2通信装置20の測定手段202は、自装置の位置を測定する手段である。測定手段202は、本実施形態では、受信手段201から識別データが供給された場合、すなわち、受信手段201が通信機器30からの識別データを受信した場合に、自装置の位置を測定する。測定された位置データは、通信機器30から発信された識別データの受信時の自装置の位置を示すことになる。測定手段202は、測定した位置を示す位置データと、供給された識別データとを送信手段203に供給する。
第2通信装置20の送信手段203は、測定手段202から供給された位置データと識別データ、すなわち、測定手段202が測定した位置であって識別データの受信時の自装置の位置を示す位置データとその識別データとを対応付けてサーバ装置40に送信する手段である。送信手段203は、例えば、サーバ装置40のIPアドレスなどの宛先を予め記憶しており、測定手段202から供給された位置データ及び識別データを、送信手段103の説明で述べたような方法で対応付けてサーバ装置40に送信する。
サーバ装置40の記憶手段401は、紛失状態にある通信機器30を識別する識別データが第1通信装置10から取得すると、その識別データを通信機器30が紛失状態であることを示す紛失データに対応付けて記憶する手段である。紛失データとは、例えば、紛失の事実の有無を示すフラグである。また、記憶手段401は、通信機器30が紛失状態になったときの第1通信装置10の位置を示す位置データ及び識別データが第1通信装置10から取得すると、その位置データをその識別データに対応付けて記憶する。
図7は、紛失管理DBの一例を示す図である。図7では、「ID001」、「ID002」、及び「ID003」という識別データが、登録されている識別データの一例として示されている。
図8は、紛失管理DBの別の一例を示す図である。図8では、記憶手段401が、「ID001」という識別データに対応付けて、第2通信装置20から送信された位置データである「位置β」を格納した紛失管理DBが示されている。記憶手段401は、このように位置データを紛失管理DBに格納することで、第2通信装置20からの位置データを識別データに対応付けて記憶する。この場合、「ID001」で識別される通信機器30のBT通信範囲を第2通信装置20が通過し、そのときの第2通信装置20の位置として「位置β」が測定されたことが表される。
第1通信装置10の要求手段104は、判定手段101により紛失状態であると判定された通信機器30に関する紛失情報をサーバ装置40に要求する手段である。紛失情報には、例えば記憶手段401に記憶された位置データの示す位置が含まれる。また、記憶手段401が日時データを記憶する場合には、その日時データの示す日時も含まれる。つまり、これらの紛失情報は、記憶手段401が記憶する識別データに対応付けて記憶されている各データによって示される情報である。
サーバ装置40の通知手段402は、第1通信装置10から要求された紛失情報をその第1通信装置10を介してユーザに通知する手段である。通知手段402は、第1通信装置10からの要求データを受け取ると、記憶手段401を参照し、その要求データにより要求されている識別データに対応付けられた各データ(例えば位置データ。記憶されている場合には日時データも)を読み出す。通知手段402は、読み出した各データと、読み出しに用いた識別データとを対応付けて第1通信装置10に送信する。これらの各データは紛失情報を構成するデータであり、その紛失情報は後述するように第1通信装置10によって表示されてユーザに通知されることになる。このように、通知手段402は、紛失情報を示す各データを送信することで、紛失情報をユーザに通知する。
第1通信装置10の表示手段105は、サーバ装置40から送信されたデータが示す紛失情報を表示する手段である。表示手段105は、例えばサーバ装置40から識別データ及び位置データを受信した場合には、識別データが示す通信機器30を表す文字列等と、位置データが示す位置を表す文字列や画像を表示する。また、表示手段105は、さらに日時データを受信した場合には、その日時データが示す日時を表す文字列等も表示する。
通知された紛失情報を参考にしてユーザAが通信機器30を発見すると、判定手段101は、発信手段301から発信された通信開始データを受信するようになるので、紛失状態ではないと判定する。判定手段101は、そうして紛失状態ではないと判定した場合には、その判定結果を示す判定データを識別データとともに送信手段103に供給する。送信手段103は、供給された判定データ及び識別データを対応付けてサーバ装置40に送信する。記憶手段401は、紛失状態ではないという判定結果を示す判定データが受信した場合には、その判定データに対応付けて受信した識別データに対応付けて記憶している紛失データ及び位置データを削除する。
情報処理システム1は、以上の構成に基づき上述した提供処理を行う。以下では、提供処理において情報処理システム1が備える各装置が行う動作について説明する。
図10は、提供処理における各装置の動作の一例を示すシーケンス図である。図10に示すステップS11、S12及びS13等は、識別データを含むBT通信の通信開始データを所定の時間の間隔で発信する通信機器30の動作を示している。これらのステップは、発信手段301が行う動作である。この例では、ステップS11及びS12においては通信機器30のBT通信範囲に第1通信装置10が所在し、発信された通信開始データを第1通信装置10が受信している。
本実施形態では、通信機器30の紛失状態を第1通信装置10が判定したときに測定された位置が紛失情報としてユーザAに提供される。ユーザAは、その紛失情報によって通信機器30を紛失したおおよその位置を知ることができるので、第1通信装置10が測定した位置を含む紛失情報なしに通信機器30を探す場合に比べて、通信機器30を発見する可能性を高めることができる。
本発明の第2実施形態について、以下、第1実施形態と異なる点を中心に説明する。第1実施形態では、第2通信装置の受信手段201が識別データを受信した場合に測定手段202が自装置の位置を測定したが、第2実施形態では、その識別データにより識別される通信機器30が紛失状態にある場合にのみ測定手段202が位置を測定する。
図11は、第2実施形態の第2通信装置及びサーバ装置の機能構成の一例を示す図である。図11では、図6に示す各手段に加え、問合せ手段204を備える第2通信装置20aと、応答手段403を備えるサーバ装置40aとが示されている。本変形例の第2通信装置20aの受信手段201は、受信した識別データを問合せ手段204に供給する。
本発明の第3実施形態について、以下、第1及び第2実施形態と異なる点を中心に説明する。第2実施形態では、第2通信装置がサーバ装置に対して問合せを行って紛失状態の有無を判断したが、第3実施形態では、サーバ装置が記憶しているデータを第2通信装置が予め取得して記憶しておき、記憶したデータに基づいて紛失状態の有無を判断する。
図12は、第3実施形態の第2通信装置及びサーバ装置の機能構成の一例を示す図である。図12では、図6に示す各手段に加え、複製手段205を備える第2通信装置20bと、サーバ装置40とが示されている。複製手段205は、サーバ装置40の記憶手段401が記憶しているデータを複製して記憶する手段である。データの複製は、周知のレプリケーション技術を用いて行われればよい。複製手段205は、記憶手段401が記憶している全ての識別データ及びそれらの識別データに対応付けられているデータを全て複製してもよいし、それらの一部を複製してもよい。
複製手段205は、第1複製方法とは異なる第2複製方法でデータを複製してもよい。第2複製方法では、複製手段205は、測定手段202が測定した位置と同じ領域に含まれる位置を示す位置データに対応付けて記憶手段401が記憶している識別データを複製して記憶する。この領域は、第2通信装置が普段所在する領域であり、ユーザBが活動する可能性の高い領域を表す。以下ではこの領域を「活動領域」という。複製手段205は、例えば、測定された位置を含む都道府県や市区町村などの領域を活動領域として用いる。また、複製手段205は、測定された位置を全て含む緯線及び経線で囲まれる四角形の領域を活動領域として用いてもよいし、それらを全て含む円形の領域を活動領域として用いてもよい。
本発明の第4実施形態について、以下、上記の各実施形態と異なる点を中心に説明する。上記の各実施形態では、測定された位置がそのまま紛失情報として提供されたが、第4実施形態では、複数の位置が測定されている場合に、それらの位置に基づいて算出された位置が紛失情報として提供される。
図13は、第4実施形態のサーバ装置の機能構成の一例を示す図である。図13では、図6に示す各手段に加え、算出手段404を備えるサーバ装置40cが示されている。算出手段404は、自装置の記憶手段401が識別データに対応付けて複数の位置データを記憶している場合に、それら複数の位置データが示す各位置に基づいて1つの位置を算出する手段である。
算出手段404は、第1及び第2通信装置の測定手段(102及び202)が位置を測定する際の無線通信の状態を考慮して1つの位置を算出してもよい。以下では、上述したGPSの技術に加え、BT通信や無線LAN(Local Area Network)の通信などの無線通信を利用して測定手段が位置を測定する場合を説明する。この測定方法は、無線通信を行う無線通信装置が多数設置されている場所で行われる。それらの無線通信装置は、上述したBT通信のように、通信を開始させるための通信開始データをくり返し発信している。その通信開始データには、それを発信する無線通信装置の位置を示すデータが含まれている。このデータを以下では「装置位置データ」という。
上述した無線通信を利用した位置の測定が行われる場合、第1及び第2通信装置の無線通信の受信能力によって、測定される位置の精度が左右される。ここでいう受信能力とは、電波を受信してデータを取り出す能力をいう。受信能力は、例えば、受信感度や分離能力などによって表される。受信感度は、受信可能な電波の強さを表す指標であり、受信感度が高いほど弱い電波でも受信可能であることを表す。分離能力は、受信した電波からノイズや他の無線通信の信号を分離する能力である。
上述した各実施形態は、それぞれが本発明の実施の一例に過ぎず、以下のように変形させてもよい。また、上述した各実施形態及び以下に示す各変形例は、必要に応じて組み合わせて実施してもよい。
サーバ装置の通知手段402は、実施形態では、第1通信装置からの要求があった場合に紛失情報を通知するといういわゆるプル型の通知を行ったが、第1通信装置からの要求がなくても通知するといういわゆるプッシュ型の通知(以下「プッシュ通知」という)を行ってもよい。通知手段402は、例えば、定期的(1日毎など)に紛失情報を通知してもよいし、第2通信装置から位置データが送信されてきて紛失情報が更新される度に通知してもよい。これにより、ユーザが紛失情報を要求する操作を行わなくても、紛失情報をユーザに提供することができる。
第1通信装置の表示手段105は、実施形態では、サーバ装置から紛失情報を示すデータを受信したら必ずその紛失情報を表示したが、前述したようなプッシュ通知が行われる場合、第1通信装置においてプッシュ通知の表示を禁止するという設定がされている場合がある。一方で、通信機器30が第三者によって持ち運ばれるというような重大な事態が生じたときには、ユーザに確実に通知されることが望ましい。本変形例では、そのような状況では、プッシュ通知を強制的に第1通信装置に表示させる。
第1通信装置が通信機器30の紛失状態を判定した場合に、近辺に所在する第2通信装置に対して通信機器30の紛失情報を収集するための処理が依頼されてもよい。
図17は、本変形例のサーバ装置及び第2通信装置の機能構成の一例を示す図である。図17では、図12と同様の各手段を備える第2通信装置20fと、図6に示す各手段に加え、依頼手段407を備えるサーバ装置40fとが示されている。この例では、第2通信装置20fの測定手段202が、例えば所定の時間の間隔(1分毎など)で繰り返し自装置の位置の測定を行い、送信手段203が、測定手段202が位置を測定する度にその位置を示す位置データをサーバ装置40fに送信する。
サーバ装置の記憶手段401は、通信機器30の識別データに対応付けて、例えば通信機器30の持ち主であるユーザの個人データを記憶してもよい。個人データは、例えばユーザの氏名、電話番号、電子メールのアドレス、SNS(Social Networking Service)のアカウントなどである。これらの個人情報は、通信機器30の識別データとともに登録されたり、あとからユーザの操作により登録されたりする。例えば、上述した依頼手段407が、第2通信装置に対して記憶処理を依頼する際に、個人データの表示も依頼してもよい。これにより、第2通信装置のユーザが紛失された通信機器30を見つけた場合に、紛失したユーザにその旨を連絡しやすいようにすることができる。
第1及び第2通信装置の各測定手段は、上記以外の方法で自装置の位置を測定してもよい。測定手段は、例えば、移動体通信の基地局との通信を利用した周知の基地局測位を行ってもよいし、ユーザの操作に応じた測位を行ってもよい。ここでいうユーザの操作とは、地名や施設名などを入力する操作や地図を表示させてその地図上の位置を示す操作などである。
第1通信装置の判定手段101は、上記以外の方法で紛失状態を判定してもよい。判定手段101は、例えば、ユーザの操作に応じて紛失状態を判定する。その場合、ユーザが紛失状態に気付いたときに、紛失したと思われるおよその時刻を入力する操作を行うことで、入力された時刻に紛失状態の判定が行われたものとしてもよい。そうすることで、例えば測定手段102が所定の時間間隔(1分毎など)で位置を測定して測定した時刻に対応付けて記憶するようにしておき、ユーザが入力した時刻に対応付けて記憶した位置を、通信機器30が紛失状態であると判定手段101が判定を行ったときの自装置の位置として測定するようにしてもよい。これにより、ユーザが紛失状態を判定する操作を紛失後すぐに行わなかった場合でも、紛失した位置により近い位置が測定されることになる。
要するに、本技術に係るサーバ装置は、第1通信装置および1以上の第2通信装置と通信を行う通信部と、紛失状態にある携帯端末の識別データを前記第1通信装置から取得すると、当該識別データを登録する登録部と、前記1以上の第2通信装置から、前記携帯端末から発信された前記識別データが当該第2通信装置にて受信された時の当該第2通信装置の位置を示す位置データと当該識別データとを取得すると、当該識別データが登録されている場合、当該位置データを出力する出力部とを備えていればよい。出力先としては、第1通信装置、前記一以上の第2通信装置のほか、サーバ内の記憶装置であってもよいし、その他の装置でもよい。また、位置データの出力は、装置から要求を受信した場合に実行されてもよいし、サーバ装置が当該出力のタイミングを決定してもよい。
また、本発明は、これらの装置のようなコンピュータを、上記の各装置を機能させるためのプログラムとしても捉えられるものである。これらのプログラムは、それを記憶させた光ディスク等の記録媒体の形態で提供されたり、インターネット等のネットワークを介して、コンピュータにダウンロードさせ、それをインストールして利用可能にするなどの形態でも提供されたりするものであってもよい。
