Detailed Description
For the purpose of making the objects, technical solutions and advantages of the present application more apparent, the embodiments of the present application will be described in further detail with reference to the accompanying drawings.
The embodiment of the application provides an information encryption and information decryption method, please refer to fig. 1, which shows a schematic diagram of an implementation environment of the method provided by the embodiment of the application. The implementation environment may include: a terminal 11 and a server 12.
The terminal 11 and the server 12 may independently implement the information encryption and information decryption methods provided in the embodiments of the present application. The terminal 11 and the server 12 can also implement the information encryption and information decryption methods provided by the embodiments of the present application through interaction. For example, the terminal 11 is installed with an application program capable of acquiring plaintext information to be encrypted, and when the application program acquires the plaintext information to be encrypted, the acquired plaintext information to be encrypted may be sent to the server 12, and the server 12 encrypts the plaintext information based on the method provided by the embodiment of the present application to obtain ciphertext information. The server 12 sends the ciphertext information to the terminal 11, and the terminal 11 decrypts the ciphertext information by the method provided by the embodiment of the application to obtain plaintext information. Or the terminal 11 is provided with an application program capable of acquiring the plaintext information to be encrypted, after the application program acquires the plaintext information to be encrypted, the terminal 11 encrypts the plaintext information based on the method provided by the embodiment of the application, after ciphertext information is obtained, the terminal 11 sends the ciphertext information to the server 12, and the server 12 decrypts the ciphertext information based on the method provided by the embodiment of the application, so as to obtain the plaintext information.
Alternatively, the terminal 11 may be any electronic product that can perform man-machine interaction with a user through one or more modes of a keyboard, a touch pad, a touch screen, a remote controller, a voice interaction or handwriting device, such as a PC (Personal Computer ), a mobile phone, a smart phone, a PDA (Personal DIGITAL ASSISTANT, a Personal digital assistant), a wearable device, a PPC (Pocket PC), a tablet computer, a smart car machine, a smart television, a smart speaker, etc. The server 12 may be a server, a server cluster comprising a plurality of servers, or a cloud computing service center. The terminal 11 establishes a communication connection with the server 12 through a wired or wireless network.
Those skilled in the art will appreciate that the above-described terminal 11 and server 12 are only examples, and that other terminals or servers that may be present in the present application or in the future are applicable and within the scope of the present application and are incorporated herein by reference.
Based on the implementation environment shown in fig. 1, the embodiment of the present application provides an information encryption method, which may be performed by a terminal or a server. Taking the example that the method is applied to a terminal, the flow of the method is shown in fig. 2, and the method comprises steps 201 to 204.
In step 201, plaintext information to be encrypted is acquired, and an encryption object corresponding to the plaintext information to be encrypted is determined.
The embodiment of the application does not limit the plaintext information, and can be any information with confidentiality requirement. Illustratively, the plaintext information may be a picture with a security requirement, a text with a security requirement, an audio with a security requirement, or a video with a security requirement.
Optionally, the terminal acquires the plaintext information through the acquisition device. For example, a conference is held at the site a, the terminal records conference video based on the video acquisition device, and the recorded conference video has a security requirement because the conference is not disclosed externally, and the conference video is plaintext information to be encrypted. Optionally, the terminal obtains the plaintext information stored in the storage space by accessing the storage space. The storage space may be a storage space of the terminal, or may be a storage space of a server communicatively connected to the terminal. For example, the user a and the user B together complete a writing work of a text a which cannot be disclosed externally, the text a is stored in a storage space of the terminal, and the terminal obtains the text a by accessing the storage space, and the text a is plaintext information.
In one possible implementation manner, when obtaining the plaintext information to be encrypted, it is further required to determine an encryption object corresponding to the plaintext information to be encrypted. Illustratively, the encrypted object corresponding to the plaintext information to be encrypted refers to the owner of the plaintext information, that is, an object that needs to keep the plaintext information secret. Taking the conference video shown in the above embodiment as the plaintext information as an example, the encryption object corresponding to the plaintext information is the conference participant. Taking the text a shown in the above embodiment as plaintext information as an example, the encrypted object corresponding to the plaintext information is the writer of the text a, that is, the user a and the user B.
It should be noted that the above examples are intended to illustrate the relationship between the encrypted object and the plaintext information, and not to limit the encrypted object, and the encrypted object may be any object that needs to keep the plaintext information secret, and the number of people of the encrypted object may be any number, which is not limited in the embodiments of the present application.
In step 202, in response to the encrypted object being a plurality of, a plurality of first voiceprint features from the plurality of encrypted objects are obtained, any one of the plurality of encrypted objects corresponding to one of the first voiceprint features.
In one possible implementation, a plaintext message corresponds to a plurality of encrypted objects, and a plurality of first voiceprint features of the plurality of encrypted objects are acquired. The manner in which the plurality of first voiceprint features are acquired includes, but is not limited to: acquiring a plurality of first audio data from a plurality of encrypted objects, wherein any encrypted object in the plurality of encrypted objects corresponds to at least one first audio data; and extracting voiceprint features of each first audio data in the plurality of first audio data to obtain a plurality of first voiceprint features.
Illustratively, the terminal provides an audio data input interface on the basis of which the encryption object inputs audio data, and the terminal takes the received audio data as the first audio data. The audio data input interface may be a MIC (microphone), or may be other devices that may be used to collect audio data, which is not limited in this embodiment of the present application. The microphone for inputting audio data may be a microphone externally connected to the terminal or may be a microphone built in the terminal. The microphone connected to the terminal may be connected by a wire or by a wireless connection.
When the encrypted object inputs the audio data based on the audio data input interface, the text read by the encrypted object can be any text or text provided by the terminal. For example, the terminal displays text on a screen for prompting an encryption object to input audio data while providing an audio data input interface. The embodiment of the application does not limit the text provided by the terminal, and can be the name of plaintext information or randomly generated characters. The terminal prompts the encrypted object when the encrypted object inputs the first audio data by displaying the text on the screen, so that the thinking time of the encrypted object when the encrypted object inputs the first audio data is reduced, and the efficiency of the terminal for acquiring a plurality of first audio data is improved. Alternatively, when the encrypted object inputs the audio data based on the audio data input interface, the audio data may be input a plurality of times, and the quality of the input audio data is improved by increasing the number of times of inputting the audio data, and the terminal acquires the first audio data with higher quality based on the quality. Regarding audio data input multiple times by the same encryption object, the content of the audio data may be the same or different, which is not limited in the embodiment of the present application. The content of the audio data refers to text read by the encryption object when the audio data is input.
In one possible implementation, since non-voice audio data, such as ambient noise, exists in the first audio data, the terminal may also pre-process the obtained first audio data before extracting the voiceprint features of each of the plurality of first audio data. The embodiment of the application is not limited to the preprocessing mode, and can be realized based on the VAD (Voice Activity Detection, voice endpoint detection) technology. For example, a start position and an end position of voice audio data in the first audio data are located based on the VAD technology, and the first audio data are segmented according to the start position and the end position, so as to obtain the voice audio data in the first audio data. By preprocessing, separation of voice audio data from non-voice audio data in the first audio data is realized, so that voiceprint features of the first audio data are extracted later more accurately.
The embodiment of the application does not limit the mode of extracting the voiceprint features of each first audio data, and may extract MFCC (Mel Frequency Cepstral Coefficents, mel-frequency cepstrum Coefficient) from the first audio data as the first voiceprint feature, extract LPCC (LINEAR PREDICTIVE CEPSTRAL coeffient, linear prediction cepstrum Coefficient) from the first audio data as the first voiceprint feature, or extract other voiceprint feature technologies. Note that, in the case where a plurality of pieces of first audio data are input to the same encryption object as shown in the above embodiment, since the voiceprint characteristics of the encryption object are independent of the content of the first audio data. Therefore, the voiceprint features extracted from the plurality of first audio data from the same encrypted object are the same, that is, the plurality of first audio data of the same encrypted object corresponds to one first voiceprint feature.
In step 203, a first hybrid voiceprint feature is determined based on the plurality of first voiceprint features.
With respect to the manner in which a first hybrid voiceprint feature is determined based on a plurality of first voiceprint features, including, but not limited to: determining a first cut order; dividing each first voiceprint feature of the plurality of first voiceprint features according to a first dividing sequence to obtain a plurality of first dividing results, wherein any one of the plurality of first voiceprint features corresponds to one first dividing result; and splicing the plurality of first segmentation results to obtain a first mixed voiceprint feature. Illustratively, the manner in which the first order of cuts is determined includes, but is not limited to, the following two ways.
The first determining mode is that the terminal determines a first division sequence based on the information of each first voiceprint feature.
The information of the first voiceprint feature may be the acquisition time of the first voiceprint feature, may be the name of the first voiceprint feature, or may be other information, which is not limited in the embodiment of the present application. When the information of the first voiceprint feature is the acquisition time of the first voiceprint feature, the terminal may arrange in the order from the early to the late based on the acquisition time of the first voiceprint feature, and use the arrangement result as the first division order. When the information of the first voiceprint feature is a name of the first voiceprint feature, the terminal may arrange according to a preset alphabetical table based on the name of the first voiceprint feature, and use the arrangement result as a first score order. Wherein the alphabetical table may be set based on empirical values. With respect to the method for acquiring the name of the first voiceprint feature, optionally, the terminal provides an audio data input interface and an information input interface, after the encrypted object inputs the first audio data based on the audio data input interface, the name of the first audio data can be input based on the information input interface, and the terminal uses the received name as the name of the first voiceprint feature corresponding to the first audio data. Of course, the operation of inputting the name of the first audio data by the encryption object based on the information input interface may also be performed before inputting the first audio data. It should be noted that, for the case that a plurality of first audio data are input to the same encrypted object shown in the above embodiment and one first voiceprint feature is obtained based on the plurality of first audio data, if names of the first audio data input by the encrypted object when the plurality of first audio data are input are different, the terminal may randomly determine a name from the plurality of names as the name of the first voiceprint feature of the encrypted object or use the last input name as the name of the first voiceprint feature of the encrypted object.
And determining a second determination mode, wherein the terminal determines a first division sequence based on the user requirement.
The user may be an encrypted object, or may be another object related to plaintext information. For example, after the terminal acquires the plurality of first voiceprint features of the plurality of encrypted objects, names of the acquired plurality of first voiceprint features are displayed on a screen, and the user can determine the order of clicking by the terminal as a first tangential order by clicking the names of the first voiceprint features in turn. Optionally, the terminal provides an information input interface, the user sequentially inputs names of the first voiceprint features based on the information input interface, and the terminal determines an order in which the user inputs the first voiceprint features as a first tangential order. Optionally, the terminal provides a plurality of sorting methods and controls corresponding to the sorting methods, and the user determines the first sorting order by triggering the controls corresponding to the sorting methods. The control corresponding to the trigger ordering method can be triggered by voice operation or by clicking operation, and the embodiment of the application is not limited to the trigger ordering method. The various sorting methods provided by the terminal are similar to those shown in the first determination mode, and will not be repeated here.
The embodiment of the application does not limit the manner of splitting the first voiceprint feature, and optionally, the n-1/n to 1 portions of the first voiceprint feature are split. Wherein n is a positive integer, which refers to the segmentation order of the first voiceprint feature. For example, the first voiceprint feature a (113344) is the first voiceprint feature to be segmented, that is, n is taken to be 1, and at this time, the first segmentation result corresponding to the first voiceprint feature a is from the start position (0) to the end position (1) of the first voiceprint feature a, that is, the first segmentation result corresponding to the first voiceprint feature a is 113344. For another example, the first voiceprint feature B (112244) is a second voiceprint feature to be segmented, that is, n is taken to be 2, and at this time, the first segmentation result corresponding to the first voiceprint feature B is from 1/2 part of the first voiceprint feature B to the end position (1), that is, the first segmentation result corresponding to the first voiceprint feature B is 244. The segmentation mode of each first voiceprint feature is determined based on the segmentation sequence of each first voiceprint feature, and the confidentiality of the first mixed voiceprint feature obtained by splicing a plurality of first segmentation results is improved by using different segmentation modes for different first voiceprint features. In addition, since the voiceprint feature data quantity reserved by the first voiceprint feature with the later segmentation order is smaller, the voiceprint feature data quantity of a plurality of first segmentation results is effectively controlled for subsequent operation.
After each first voiceprint feature is segmented to obtain a plurality of first segmentation results, the plurality of first segmentation results can be spliced to obtain a first mixed voiceprint feature. In one possible implementation manner, the order of splicing the plurality of first division results is the same as the first division order, and the terminal splices the plurality of first division results according to the first division order to obtain a first mixed voiceprint feature, where the process is shown in formula 1.

Wherein n is a positive integer, used for representing the segmentation order of the first voiceprint feature, t n refers to the nth first voiceprint feature to be segmented, F (t n) refers to the n-1/n to 1 part of the nth first voiceprint feature to be segmented, and F (t n-1)+F(tn) refers to the concatenation of F (t n-1) and F (t n). Taking n as 2 as an example, F (t 1) is 11, F (t 2) is 22, F (t 1)+F(t2) =1122, i.e. the first hybrid voiceprint feature is 1122.
