Detailed Description
In order to make the objects, technical solutions and advantages of the embodiments of the present invention clearer, the technical solutions in the embodiments of the present invention will be clearly and completely described below with reference to the drawings in the embodiments of the present invention, and it is obvious that the described embodiments are some, but not all, embodiments of the present invention. All other embodiments, which can be derived by a person skilled in the art from the embodiments given herein without making any creative effort, shall fall within the protection scope of the present invention.
First, a voiceprint control method of an intelligent presenter according to an embodiment of the present invention will be described with reference to fig. 1.
The intelligent presenter includes a memory element having pre-stored therein registered voiceprint features, typically of the owner of the intelligent presenter, which may also be used to store other files, such as presentations and the like.
As shown in fig. 1, the voiceprint control method of the intelligent presenter comprises the following steps:
step S100: and acquiring the decrypted voice information.
It will be appreciated that in the practice of applying the method, the decrypted voice information may be voice information provided to the current user, or voice information provided by the owner of the intelligent presenter to the current user, which is used to decrypt the memory element of the intelligent presenter.
Step S200: and acquiring the decrypted voiceprint characteristics based on the decrypted voice information.
The decrypted voiceprint feature is extracted from the decrypted voice message obtained in step S100, and may include, but is not limited to, a tone color feature (frequency feature) in the decrypted voice message, and the like.
Step S300: the memory element is decrypted when the decrypted voiceprint feature matches a registered voiceprint feature that is pre-stored in the memory element.
That is, the decrypted voiceprint feature contained in the decrypted voice message input to the intelligent presenter during decryption is compared with the registered voiceprint feature prestored in the storage element, and if the decrypted voiceprint feature and the registered voiceprint feature are matched, decryption can be achieved.
The voiceprint control method of the intelligent demonstrator can automatically extract the voiceprint characteristics of the voice information, and the pre-stored and compared characteristics are the voiceprint characteristics, so that a user does not need to memorize the voice information of specific contents, the unlocking process is simple, specific interaction is not needed, and the unlocking can be realized only by the user speaking normally in the using process.
The voiceprint control method of the intelligent demonstrator of the embodiment of the invention combines the biological characteristics with the cryptography, can conveniently realize the decryption of the intelligent demonstrator, does not need special operation action in the decryption process, and has natural interaction.
In some embodiments, the voiceprint control method of the intelligent presenter may further include:
step S000: and triggering a voiceprint registration condition, acquiring a registered voiceprint characteristic and storing the registered voiceprint characteristic in a storage element.
In the practice of applying the method, the above steps are mainly used for registering the voiceprint feature, it should be noted that, the intelligent presenter is encrypted at the time of factory shipment, and the data stored inside the storage element of the intelligent presenter is: copy-proof, screen-capture-proof, write-in-proof and printing-proof protection states.
When the voiceprint registration condition is triggered, a decryption password (registration voiceprint feature) for decrypting the intelligent demonstrator is equivalently set and stored in the storage element so as to facilitate comparison and verification in a subsequent decryption process.
In an actual implementation, the condition for triggering voiceprint registration in step S000 includes: the intelligent demonstrator is electrically connected with the computer for the first time after detecting that the intelligent demonstrator leaves a factory or is reset.
It can be understood that the intelligent demonstration device is encrypted when being shipped from a factory, and a matching program is arranged in a storage element of the intelligent demonstration device, when the intelligent demonstration device is electrically connected with a computer for the first time, for example, when an adapter of the intelligent demonstration device is inserted into a USB interface of the computer for the first time after being shipped from a factory or being reset, the matching program arranged in the storage element automatically runs and is installed, and enters a voiceprint registration interface.
In an actual implementation, the acquiring the registered voiceprint feature in step S000 includes: and receiving the encrypted voice information, and acquiring the registered voiceprint characteristics based on the encrypted voice information.
After the voiceprint registration condition is triggered, the user completes the occurrence (encryption of voice information) according to the guidance of the registration application interface, the intelligent demonstrator receives the sounding and acquires the registration voiceprint features in the sound, and the registration voiceprint features can be stored in the storage element or can be synchronized with the cloud.
The registered voiceprint characteristics are obtained based on the encrypted voice information and can be obtained through a built-in voiceprint extraction model.
It should be noted that the encrypted voice message may include a preset voice keyword.
That is to say, in the voiceprint registration stage, only when the intelligent presenter acquires the voice information containing the preset voice keyword, the registered voiceprint feature can be extracted based on the voice information, so that registration is realized, and even only when the intelligent presenter acquires the preset voice information, the registered voiceprint feature can be extracted based on the voice information, so that registration is realized.
In this way, the voiceprint control method can more accurately realize voiceprint registration and prevent improper registration, for example, even after the intelligent presenter meets the condition of triggering voiceprint registration, a user can continue to use the intelligent presenter without registering, but the data stored in the storage element of the intelligent presenter is as follows: copy-proof, screen-capture-proof, write-in-proof and printing-proof protection states.
In some embodiments, the step S100 of obtaining the decrypted voice information may be obtained through a built-in microphone of the intelligent presenter, and the microphone may include a microphone array.
In some embodiments, the step S200: and acquiring the decrypted voiceprint characteristics based on the decrypted voice information, wherein the decrypted voiceprint characteristics can be obtained through a built-in voiceprint extraction model.
In some embodiments, the decrypting the storage element in step S300 when the decrypted voiceprint feature matches a registered voiceprint feature pre-stored in the storage element includes: and matching the decrypted voiceprint characteristics with the registered voiceprint characteristics to obtain a matching value, and decrypting the storage element when the matching value is greater than a preset value.
It should be noted that, because the directly compared voiceprint features are obtained by the decryption method, it is not necessary for the current user to speak specific voice information, for example, when the current user uses other functions of the intelligent presenter, once uttering, the voice can be automatically verified to complete decryption of the storage element.
The preset value is preset, when the preset value is set to be higher, the security is higher, but the decryption is easy to fail, and when the preset value is set to be higher, the security is lower, but the decryption is easy.
Of course, when the decrypted voiceprint feature does not match the registered voiceprint feature, for example, when the match value is below a predetermined value, the storage element is not decrypted.
A specific embodiment of the present invention is described below.
The voiceprint control method of the intelligent demonstrator comprises the following steps: the intelligent demonstrator detects that the intelligent demonstrator is electrically connected with the computer for the first time after leaving the factory or after being reset, namely, the intelligent demonstrator triggers voiceprint registration conditions, receives specified encrypted voice information, acquires registered voiceprint characteristics based on the encrypted voice information, and stores the registered voiceprint characteristics in the storage element; acquiring decrypted voice information; acquiring a decrypted voiceprint characteristic based on the decrypted voice information; and when the decrypted voiceprint characteristics are matched with the registered voiceprint characteristics prestored in the storage element, decrypting the storage element.
