[0052] It should be understood that the specific embodiments described herein are only used to explain the present invention and are not intended to limit the present invention. In order to enable those skilled in the art to better understand the present application, the technical solutions in the embodiments of the present application will be clearly and completely described below in conjunction with the drawings in the embodiments of the present application. Obviously, the described embodiments are only embodiments of a part of the present application, not all embodiments. Based on the embodiments in the present application, all other embodiments obtained by ordinary technicians in the field without making creative work should fall within the scope of protection of the present application.

[0053] It is understandable that the user information and other related data involved in the specific implementation methods of this application are all data that the user permits or agrees to obtain, and the collection, use and processing of the relevant data comply with the relevant laws, regulations and standards of the relevant countries and regions.

[0054] The present invention provides a communication identity authentication method, referring to Figure 1 , Figure 1 This is a flow chart of the first embodiment of the communication identity authentication method of the present invention applied to the initiating end. The method is applied to the initiating end. The method comprises the steps of:

[0055] Step S11, obtaining the user identity information of the initiating end;

[0056] The initiating end is the terminal that initiates the call event; correspondingly, the receiving end is the terminal that receives the call event.

[0057] User identity information is used to indicate the identity of the user at the initiating end; user identity information includes but is not limited to the mobile phone number of the initiating end and the user's identity information; the identity information includes but is not limited to the user's name, place of origin, and location.

[0058] The method for obtaining specific user identity information can be set based on the type of information actually needed to be obtained; for example, the user identification card SIM can be read to obtain the registration information of the SIM card, which may include the mobile phone number, the name corresponding to the mobile phone number, the place of origin and other information; the positioning signal can also be read to obtain the location information.

[0059] Step S12, converting the user identity information into an identity audio signal, wherein the frequency of the identity audio signal is outside the sound frequency range audible to human ears;

[0060] The identity audio signal refers to the user identity information in the form of an audio signal; it is understandable that the user identity information is in a format that cannot be directly transmitted through audio; and in a call event, the audio signal is transmitted between the initiating end and the receiving end. Therefore, the user identity information needs to be converted into the form of an audio signal so that the user identity information can be sent in the form of an audio signal, that is, the identity audio signal, to realize the transmission of the user identity information.

[0061] It can be understood that after the user identity information is converted into an identity audio signal; since in a call event, the user's call content is also transmitted in the form of an audio signal, therefore, after the identity audio signal is sent to the receiving end, it may be heard by the user, affecting the playback effect of the call audio signal; therefore, in this embodiment, the frequency of the identity audio signal is set outside the sound frequency range that the human ear can hear; generally, the human ear can hear sounds in the range of 20 to 20,000 Hz, therefore, the frequency of the identity audio signal can be set outside 20 to 20,000 Hz, so that when the identity audio signal is transmitted to the receiving end, the user will not hear the content corresponding to the identity audio signal, thereby avoiding the playback of the call audio signal being affected by the identity audio signal; and in actual applications, due to the poor anti-interference ability of low-frequency audio signals, the frequency of the identity audio signal can be set to >20,000 Hz.

[0062] Step S13, acquiring a call audio signal, and synthesizing the call audio signal with the identity audio signal to obtain a target audio signal;

[0063] The call audio signal is the audio signal corresponding to the user's call content in the call event; see Figure 3 In a call event, the speech content of the users at the initiating end and the receiving end is collected by the microphone MIC and converted into a call audio signal. After the call audio signal is sent to the base station, the base station forwards the call audio signal to the receiving end or the initiating end. After the receiving end or the initiating end decodes the received call audio signal to obtain a specific content signal, the content signal is played through the speaker SPEAK to realize the call between the initiating end and the receiving end user.

[0064] It can be understood that at the initiating end, the identity audio signal needs to be sent to the receiving end, that is, the initiating end needs to send the identity audio signal and the call audio signal at the same time. Therefore, in this embodiment, the identity audio signal and the call audio signal are synthesized to obtain the target audio signal. When the target audio signal is sent to the receiving end, the identity audio signal and the call audio signal can be sent to the receiving end at the same time.

[0065] Step S14: sending the target audio signal to a receiving end, so that the receiving end performs identity authentication based on the target audio signal.

[0066] After the target audio signal is obtained, the target audio signal can be sent to the receiving end.

[0067] It can be understood that when a call event is just established, the identity audio signal is obtained and synthesized with the call audio signal to obtain the target audio signal and sent to the receiving end. After successful sending, the call audio signal can be sent directly afterwards without repeatedly synthesizing the target audio signal, that is, there is no need to repeatedly send the identity audio signal.

[0068] Reference Figure 2 , Figure 2 This is a flow chart of the first embodiment of the communication identity authentication method of the present invention applied to a receiving end. The method is applied to a receiving end and comprises the following steps:

[0069] Step S21, receiving a target audio signal sent by an initiator;

[0070] After the call event is established, the receiving end receives the target audio signal sent by the initiating end.

[0071] It is understandable that when a call event is just established, the receiving end receives the target audio signal sent by the initiating end.

[0072] Step S22, performing signal separation on the target audio signal to obtain a call audio signal and an identity audio signal, and playing the call audio signal; wherein the frequency of the identity audio signal is outside the sound frequency range audible to human ears;

[0073] It is understandable that the target audio signal includes a call audio signal and an identity audio signal, and the call audio signal and the identity audio signal respectively indicate different types of information. Therefore, the target audio signal needs to be separated to obtain the call audio signal and the identity audio signal.

[0074] Since the frequency of the identity audio signal is outside the sound frequency range audible to the human ear, the identity audio signal can be obtained by removing the audio within 20 to 20,000 Hz in the target audio signal, and the audio within 20 to 20,000 Hz is used as the call audio signal.

[0075] After obtaining the call audio signal, the call audio signal can be played, and the specific playing process will not be repeated here.

[0076] Step S23, parsing the identity audio signal to obtain the user identity information of the initiating end;

[0077] Step S24, displaying the user identity information on the receiving end.

[0078] It is understandable that the identity audio signal is in the form of an audio signal and cannot be displayed directly. Therefore, it is necessary to parse the identity audio signal to obtain the user identity information in the form of data so that the user identity information can be displayed.

[0079] Specifically, the identity audio signal can be parsed to obtain information such as mobile phone number and name in text form, and displayed on the display screen of the receiving end; when the user identity information is displayed, the user identity information can be displayed on the call software of the initiating end.

[0080] It can be understood that when a call event is just established, the target audio signal sent by the initiator is received, and the corresponding identity audio signal and call audio signal are obtained; and after successful acceptance, the call audio signal is directly received to directly play the call audio signal.

[0081] It should be noted that, in a call event, the initiating end is the active end of the call event, and the receiving end is the passive end of the call event. Therefore, from a security perspective, the receiving end needs to confirm the identity of the initiating end user based on the relevant information of the initiating end; therefore, in this embodiment, the initiating end is set to send its corresponding user identity information, and the receiving end is set not to send its corresponding user identity information, so that the receiving end can determine the identity of the initiating end user, while the initiating end cannot know the identity of the receiving end user, thereby ensuring the information security of the receiving end user.

[0082] In other embodiments, the user identity information of the receiving end user and the call audio signal of the receiving end can also be synthesized into a target audio signal and sent to the initiating end, so that both the initiating end and the receiving end can know the identity of the other user; further, an identity information trigger button can be set on the receiving end. After the receiving end user triggers the identity information trigger button, the user identity information corresponding to the receiving end and the call audio signal of the receiving end can be synthesized into a target audio signal and sent to the initiating end, so that the user of the receiving end can choose whether to send the user identity information to the initiating end based on his or her actual needs. The initiating end can also set an identity information trigger button.

[0083] This embodiment converts the user identity information of the initiating end into an identity audio signal and superimposes it on the call audio signal, so that the receiving end can determine the user identity of the initiating end based on the received target audio signal; at the same time, the frequency of the identity audio signal is set to be outside the sound frequency range audible to the human ear, so that the superposition of the identity audio signal will not affect the user's normal call.

[0084] Further, see also Figure 3 In the second embodiment of the communication identity authentication method of the present invention proposed based on the first embodiment of the present invention, the step S11 includes the steps of:

[0085] Step S111, reading the user identification card of the initiating end to obtain the mobile phone number and identity information corresponding to the initiating end;

[0086] Step S112, generating the user identity information including the mobile phone number and the identity information.

[0087] The SIM card will store relevant information during registration, such as user name and other identity information, and mobile phone number; it is understandable that the information in the SIM card needs to be verified when a call is initiated. Therefore, the information in the SIM card is generally fixed. Therefore, reading the mobile phone number and identity information from the SIM card is more accurate and can prevent the relevant information from being modified.

[0088] After obtaining the mobile phone number and identity information, the user identity information can be generated based on the mobile phone number and identity signal.

[0089] Further, in a third embodiment of the communication identity authentication method of the present invention proposed based on the first embodiment of the present invention, the step S12 includes the steps of:

[0090] Step S121, inputting the user identity information into an encryption chip, so as to encrypt the user identity information by using an encryption key in the encryption chip to obtain ciphertext information, wherein the encryption keys of the encryption chips of the initiating end and the receiving end are the same;

[0091] Step S122: convert the ciphertext information into the identity audio signal.

[0092] User identity information may be leaked during transmission, affecting the security of user information. Therefore, before transmitting the user identity information, the user identity information is encrypted in this embodiment to obtain ciphertext information, thereby avoiding leakage of the user identity information.

[0093] The type of specific encryption chip can be set based on actual needs.

[0094] It can be understood that since the user identity information is encrypted at the initiating end, the receiving end needs to decrypt the ciphertext information to obtain the user identity information after obtaining the corresponding ciphertext information; and the initiating end encrypts the user identity information through the encryption key to obtain the ciphertext information, so the receiving end needs to decrypt the ciphertext information through the same encryption key to obtain the user identity information. Therefore, the encryption keys stored in the encryption chips stored at the initiating end and the receiving end need to be set to be the same.

[0095] After obtaining the ciphertext information, the initiator can convert the ciphertext information into an identity audio signal.

[0096] Furthermore, the step S235 includes the steps of:

[0097] Step S2351, inputting the ciphertext information into the encryption chip to decrypt the ciphertext information using the encryption key in the encryption chip to obtain the user identity information, wherein the encryption keys of the encryption chips at the initiator and the receiver are the same.

[0098] After receiving the ciphertext information, the receiving end decrypts the ciphertext information by applying the same encryption key as the initiating end to obtain the user identity information.

[0099] Furthermore, the step S122 includes the steps of:

[0100] Step S1221, determining the ciphertext characters contained in the ciphertext information;

[0101] Step S1222, for each of the ciphertext characters, matching a target frequency corresponding to the ciphertext character, wherein the target frequency is outside the sound frequency range audible to human ears;

[0102] Step S1223, generating an audio sub-signal with a frequency of the target frequency, wherein the length of each of the audio sub-signals is a preset length;

[0103] Step S1224: Combine the audio sub-signals according to the order of the corresponding ciphertext characters in the ciphertext information to obtain the identity audio signal.

[0104] The ciphertext information is composed of multiple ciphertext characters; the ciphertext characters include but are not limited to English characters and numbers; for example, the ciphertext character can be one of lowercase letters a to z, one of uppercase letters A to Z, or one of numbers 0 to 9; multiple ciphertext characters are combined to obtain the ciphertext information in the form of a string.

[0105] In this embodiment, an audio sub-signal is generated with one ciphertext character as a unit, and one ciphertext character corresponds to one audio sub-signal; at the same time, the length of each audio sub-signal is the same, which is a preset length. The specific value of the preset length can be set based on actual needs, such as 100ms.

[0106] Take the ciphertext information abc as an example, which includes three ciphertext characters a, b, and c, and the length of the audio sub-signal corresponding to each ciphertext character is 100ms, that is, the length of the identity audio signal corresponding to the ciphertext information is 300ms. It can be understood that in actual applications, there may be a situation where adjacent ciphertext characters are the same. Therefore, in this embodiment, the length of each audio sub-signal is set to be the same, so that the audio sub-signals can be divided first, and then the ciphertext characters corresponding to the audio sub-signals can be determined, so that even if the adjacent ciphertext characters are the same, the ciphertext information can be accurately obtained.

[0107] Different target frequencies are set for different ciphertext characters; for example, the frequency of the audio sub-signal corresponding to the ciphertext character a, that is, the target frequency is 20.1kHz, the frequency of the audio sub-signal corresponding to the ciphertext character b, that is, the target frequency is 20.2kHz, and the frequency of the audio sub-signal corresponding to the ciphertext character c, that is, the target frequency is 20.3kHz; the audio sub-signals are combined based on the order of abc in the ciphertext signal to obtain a 300ms identity audio signal of {20.1kHz, 20.2kHz, 20.3kHz}.

[0108] It is understandable that the numerical correspondence between specific ciphertext characters and target frequencies can be set based on actual needs.

[0109] The type of the audio sub-signal can be set based on actual needs. For example, in this embodiment, the audio sub-signal preferably uses a sine wave. The specific audio sub-signal generation formula is:

[0110]

[0111] Among them, MAX_VOLUME is the amplitude of the audio sub-signal; frame is the position of the sampling point; sample_rate is the sampling rate; unit_sample is the sampling point of each syllable, where unit_sample = duration of each syllable × sample_rate; frequency is the target frequency.

[0112] Among them, the frequency F of the generated sine wave is:

[0113]

[0114] Furthermore, the step S23 comprises the steps of:

[0115] Step S231, dividing the identity audio signal into segments with a preset length to obtain a plurality of audio sub-signals;

[0116] Step S232, for each of the audio sub-signals, detecting a target frequency corresponding to the audio sub-signal, wherein the target frequency is outside a sound frequency range audible to human ears;

[0117] Step S233, matching the ciphertext characters corresponding to the target frequency;

[0118] Step S234, combining the ciphertext characters according to the order of the corresponding audio sub-signals in the identity audio signal to obtain ciphertext information;

[0119] Step S235: decrypt the ciphertext information to obtain the user identity information.

[0120] After the receiving end obtains the identity audio signal, since the lengths of the audio sub-signals are consistent, the identity audio signal can be divided into multiple audio sub-signals by a preset length.

[0121] The frequency of each audio sub-signal is detected respectively; specifically, the frequency of the audio sub-signal, that is, the frequency of the sine wave, can be obtained by fast Fourier transform, and after the frequency of the sine wave is obtained, the target frequency can be obtained, that is, the target frequency is:

[0122]

[0123] It can be understood that the numerical correspondence between the ciphertext characters and the target frequencies in the receiving end is consistent with that in the initiating end, so after determining the target frequency of each audio sub-signal, the corresponding ciphertext characters can be obtained;

[0124] Then, the corresponding ciphertext characters are combined based on the order of the audio sub-signals in the identity audio signal to obtain the ciphertext information.

[0125] For example, the identity audio signal is 300ms of {20.1kHz, 20.2kHz, 20.3kHz}; the identity audio signal is divided into 100ms to obtain three audio sub-signals of 20.1kHz, 20.2kHz, and 20.3kHz. The three audio sub-signals correspond to three ciphertext characters a, b, and c respectively. A, b, and c are combined based on the order of the audio sub-signals in the identity audio signal to obtain the ciphertext information of abc.

[0126] After obtaining the ciphertext information, the ciphertext information can be decrypted to obtain the user identity information.
