The decryption algorithm can automatically trigger the generation of a password according to a certain frequency. The microphone plug 13 is used to connect the screen unlocking device 1 and the electronic device 2.

Referring to FIG. 3, it is an operating environment diagram of a preferred embodiment of the system for unlocking an electronic device by using the screen unlocking device. In the present embodiment, the system 20 for unlocking the electronic device by the screen unlocking device (hereinafter referred to as "the screen unlocking system 20") is installed and operates in the electronic device 2. The electronic device 2 further includes, but is not limited to, a storage device 21, a processor 22, and a microphone interface 23. The storage device 21 is configured to store the code of the screen unlocking system 20, the decryption algorithm, the data, and the like. The storage device 21 may be the memory of the electronic device 2 itself, or may be an external memory card, such as an SD card. (Secure Digital Card, secure digital card), etc. The decryption algorithm is the same as that in the screen unlocking device 1, and the password can be automatically triggered according to a certain frequency, and the generated password is identical to the password generated by the decryption algorithm in the screen unlocking device 1.

In this embodiment, after the microphone plug 13 is inserted into the microphone interface 23 of the electronic device 2, the microprocessor 12 communicates with the electronic device 2 through the microphone interface 23, and the unlocking algorithm generated by the decryption algorithm in the screen unlocking device 1 is unlocked. The password corresponds to the audio information of the note to the electronic device 2. The electronic device 2 receives the audio information, and compares the audio information with the audio information of the password generated in the electronic device 2, and if the audio information is consistent with the audio information of the password generated in the electronic device 2, Then issue a screen unlock command. The electronic device 2 can be an electronic device with a microphone interface 23 such as a computer or a laptop.

The screen unlocking system 20 can be divided into one or more modules, the one or more modules being stored in the storage device 21 and configured to be configured by one or more processors (this embodiment is A processor 22) is executed to complete the present invention. For example, the screen unlocking system 20 is divided into a pre-stored module 201, a receiving module 202, a determining module 203, an alarm module 204, and a prompting module 205. The module referred to in the present invention is a program segment capable of performing a specific function, and is more suitable for describing the execution process of the software in the electronic device 2 than the program. The detailed functions of each module will be in the flowchart of FIG. 4 to be described later. Make a detailed description.

Referring to Figure 4, there is shown a flow chart of a preferred embodiment of the screen unlocking method of the present invention. The order of the steps in the flowchart may be changed according to different requirements, and some steps may be omitted or combined.

In step S01, the pre-stored module 201 pre-stores the decryption algorithm in the electronic device 2. In this embodiment, the decryption algorithm is the same as that in the screen unlocking device 1, and the password can be automatically triggered according to a certain frequency, such as automatically generating an unlock password once in ten seconds, and the generated password and screen unlocking device 1 The decryption algorithm in the generated password is consistent.

Step S02, when the screen of the electronic device 2 is in the locked state, the receiving module 202 receives the information that the screen unlocking device 1 is inserted into the microphone interface 23, and activates the unlocking screen in the screen of the electronic device 2 when receiving the insertion information. Show. In this embodiment, when the screen of the electronic device 2 is in the locked state, an unlocking icon of a lock shape or any other graphic is displayed on the screen of the electronic device 2, after the user clicks the unlocking icon. The electronic device 2 enters an unlock mode.

In step S03, after receiving the information that the user clicks the unlocking icon to enter the unlock mode, the receiving module 202 receives the audio information of the unlocking password sent by the screen unlocking device 1.

In this embodiment, after the screen unlocking device 1 is inserted into the microphone interface 23, the microprocessor 12 communicates with the electronic device 2 through the microphone interface 23, and converts the unlocking password generated by the decryption algorithm in the screen unlocking device 1 into The audio information corresponding to the note is sent to the electronic device 2, and the receiving module 202 receives the audio information. The unlocking password is audio information composed of digits in the cipher matrix corresponding to different notes. For example, when the unlocking password generated by the decryption algorithm trigger is “A3D8F4”, referring to FIG. 2, the digit in the corresponding crypto matrix is “7875985”, and the digit “7875985” corresponds to different notes to form an audio. News. The receiving module 202 can also provide a setting interface for setting the complexity of the unlocking password. The complexity of the unlocking password includes setting the number of unlocking passwords generated by the unlocking algorithm and the unlocking password in the password matrix. The note corresponding to the digit in the digit.

In step S04, the determining module 203 determines whether the audio information corresponding to the unlocking password generated in the electronic device 2 is consistent with the audio information. When the audio information does not match the audio information corresponding to the unlock password generated by the electronic device 2, step S05 is performed; when the audio information is consistent with the audio information corresponding to the unlock password generated by the electronic device 2, step S07 is performed.

In step S05, the determining module 203 determines whether the current number of unlocking times exceeds a preset value (for example, three times). If the current unlocking number does not exceed the preset value, the process returns to step S03; if the current unlocking number exceeds the preset value, step S06 is performed.

In step S06, the alarm module 204 activates an alarm mechanism of the electronic device 2, such as emitting a drip sound.

In step S07, the prompting module 205 prompts the user to successfully unlock the screen and enters the system.

It should be noted that the above embodiments are only for explaining the technical solutions of the present invention and are not intended to be limiting, and the present invention will be described in detail with reference to the preferred embodiments. Modifications or equivalents are made without departing from the spirit and scope of the invention.
