手持装置解锁系统、方法及手持装置;System and Method for Unlocking Handheld Device, and Handheld Device

摘要

本发明提供一种手持装置解锁系统、方法及手持装置。该方法包括：在解锁手持装置时，用户确认一组解锁密码的输入后，获取麦克风采集的语音讯号；将获取的语音讯号进行频谱转换以得到音频频谱影像；对音频频谱影像进行截取得到截取的频谱影像；将截取的频谱影像记录为一组解锁密码以及按输入顺序定义多组解锁密码的顺序；以及在记录的解锁密码的组数达到预定值，并且每一组输入的解锁密码与存储单元中处于同一顺序位置的解锁密码的相似度大于或等于预设相似值，解锁手持装置。; processing the audio signals to obtain frequency spectrum image; selecting a part from the frequency spectrum image to obtain selected spectrum image; recording the selected spectrum image as an unlocking password and defining an order of a number of input unlocking passwords; and unlocking the handheld device when the quantity of the unlocking passwords reaches a preset value, and the similarity value between each unlocking password and a stored password which position in a sequence is the same as the unlocking password.
