Password authentication method and device based on vibration frequency

Abstract

The invention discloses a password authentication method and device based on a vibration frequency, which are used for authenticating a digital password of an electronic device. The method comprises the following steps that: a vibration and frequency detection unit detects vibration and the vibration frequency H of the vibration; the vibration and frequency detection unit is pre-stored with a frequency range K; if H is not within the range K, the vibration is ineffective, and the authentication is finished, otherwise, the vibration is effective, and a counting module records the intra-group vibration times according to the time recorded by a timing module; a memory sequentially stores the intra-group vibration times; and when the intra-group vibration times is consistent with the digital password stored in the memory, an execution unit executes operation. The device comprises the vibration and frequency detection unit, the timing module, the counting module, the memory, a comparator and the execution unit. The password authentication method and the password authentication device has the beneficial effect that the inter-group vibration times is generated according to the detected vibration and the detected vibration frequency; and when the intra-group vibration times is consistent with a preset password, the execution unit executes operation.

Description

technical field [0001] The present invention relates to a password verification method and device, more specifically, to a vibration frequency-based password verification method and device. Background technique [0002] Along with the development of science and technology and the progress of technology, the electronic device that needs password verification such as button code to open the door, wireless remote control code to open the door is used very extensively in China. This type of electronic device generally includes a control panel or a wireless remote control for inputting password numbers, but it may also be encountered: the control panel is artificially damaged, the remote control is damaged, or the remote control is forgotten. effective action. Contents of the invention [0003] One of the technical problems to be solved by the present invention is to address the defects of the prior art that the electronic device will not be able to perform effective actions o...
