Zusammenfassung: | PROBLEM TO BE SOLVED: To provide a door unlocking method utilizing voice modulation, an asset usage leasing method, and a system using the methods.SOLUTION: A door 212 has a voice receiver. A door unlocking method includes the steps of: storing an unlocking sequence in a mobile device 202; performing a voice modulation to the unlocking sequence to generate a voice modulation voice print signal, the frequency range of the voice modulation voice print signal being a voice frequency; issuing the voice modulation voice print signal via a speaker of the mobile device; performing a voice demodulation in order to obtain the unlocking sequence when the voice receiver 213 receives the voice modulation voice print signal; and comparing whether the unlocking sequence corresponds with a standard, and determining whether or not to unlock the door.
【課題】音声変調を利用したドア解錠方法、資産使用権リース方法及びそれを使用するシステムを提供する。【解決手段】ドア212は、音声受信装置を有し、ドア解錠方法は、モバイルデバイス202中に、解錠シーケンスを記憶する工程と、解錠シーケンスに対し音声変調を行い、音声変調声紋信号を生成し、そのうち、音声変調声紋信号の周波数範囲は音声周波数である工程と、モバイルデバイスのスピーカーを介して、音声変調声紋信号を発出する工程と、音声受信装置213が音声変調声紋信号を受信したとき、解錠シーケンスを得るために音声復調を行う工程と、解錠シーケンスが規範に符合するか否かを比較して、ドアを解錠するか否かを判定する工程とを設けた。【選択図】図2 |
