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.
The embodiment of the invention provides a conversation privacy protection method, electronic equipment and a computer readable storage medium. The conversation privacy protection method can be applied to an electronic device side and executed by the electronic device, and the electronic device provided by the embodiment of the invention includes but is not limited to electronic devices such as mobile phones, tablet computers, wearable devices and the like.
Fig. 1 is a flowchart illustrating a call privacy protection method according to an embodiment of the present invention. Referring to fig. 1, the call privacy protection method includes step S110, step S120, and step S130. The following describes the call privacy protection method in the exemplary embodiment of fig. 1 in detail.
Referring to fig. 1, in step S110, when the user makes a call through the electronic device, a secure call range corresponding to the user is determined, and an overhearing distance between a listener located within the secure call range and the user is acquired.
In an example embodiment, a safe communication distance is marked through big data, experiments and the like, a user who carries out communication by the handheld electronic device is taken as a center, and the safe communication distance is taken as a radius to determine a safe communication range. The distance between the listener and the user in the call is denoted as the listening distance. When a user communicates through the electronic equipment, the listening distance between a listener and the user within a safe communication range is acquired.
In an example embodiment, acquiring the listening distance between the listener and the user within the secure call range includes: periodically acquiring an environment image of a user through a camera of the electronic equipment; judging whether a listener exists in a safe call range or not based on the environment image; and if so, acquiring the overhearing distance between the listener and the user within the safe call range according to the environment image.
In an example embodiment, when a user calls through an electronic device, the number of listeners located within a safe call range is obtained. When the number of the listeners is 0, that is, all the listeners do not fall within the secure call range any more, the call privacy protection method in the embodiment need not be used.
In an exemplary embodiment, the safe call distance is a distance at which a listener cannot hear a sound emitted from a handle of an electronic device after the handle of the electronic device is normally sounded during a call made by a user using the electronic device. If the listening distance of a certain listener is smaller than the safe calling distance, the listener can listen to the sound emitted by the handle of the electronic equipment, and at the moment, the calling privacy of the user is infringed, personal information may be leaked, and it is necessary to start the calling privacy protection method in the embodiment; if the listening distance of a certain listener is greater than or equal to the safe calling distance, the listener cannot hear the sound emitted by the handle of the electronic device, and the calling privacy of the user is safe at this time, and the calling privacy protection method in the embodiment does not need to be started.
In an example embodiment, the electronic device used by the user in the call may be a common single-screen electronic device, or may be a dual-screen electronic device.
In step S120, a target interference source is selected from a plurality of preset noise interference sources according to the overhearing distance, and the interference strength of the target interference source is set.
In an example embodiment, selecting a target interference source from a plurality of preset noise interference sources according to the overhearing distance, and setting the interference strength of the target interference source includes: selecting the nearest listening distance with the minimum value from the listening distances; selecting a target interference source corresponding to the nearest overhearing distance from a plurality of preset noise interference sources based on the mapping relation between the preset overhearing distance and the noise interference source; and setting the interference intensity of the target interference source as the interference intensity corresponding to the nearest overhearing distance based on the preset mapping relation between the overhearing distance and the interference intensity.
In an example embodiment, a plurality of different types of noise interference sources are pre-selected and stored in the electronic device, and each noise interference source can be adjusted to emit interference noise with different interference intensity. The noise interference source is screened out through big data, experiments and other modes. For example, noise interference sources of different types are marked as interference noise a, interference noise B, interference noise C … …, wherein the interference effect of the interference types on the listeners is ordered such that interference noise a is smaller than interference noise B is smaller than interference noise C. A minimum interference unit distance H is preset as a minimum interference strength unit, for example, the minimum interference unit distance H is 1 meter. For each increase of H, the interference effect of the corresponding type of noise interference source is reduced. The mapping relationship between the overhearing distance and the noise interference source is preset, for example, interference noise a corresponds to 3H, interference noise B corresponds to 2H, and interference noise C corresponds to 1H. When the overhearing distance is farther, the interference effect of the interference noise source of the corresponding type is smaller, for example, the overhearing distance is 3 meters, and the interference noise A with the minimum interference effect corresponds to; the overhearing distance is 2 meters, and corresponds to interference noise B with better interference effect than the interference noise A; the overhearing distance is 1 meter, corresponding to the interference noise C with the maximum interference effect.
The interference intensity of the noise interference source is the sound production loudness of the noise interference source. The sounding loudness E is the minimum sounding loudness unit, and the corresponding sounding loudness is increased gradually when the distance H of the minimum interference unit is increased. The mapping relationship between the overhearing distance and the interference strength is preset, for example, 3H corresponds to 1E, 2H corresponds to 2E, and 1H corresponds to 3E. When the overhearing distance is farther, the sounding loudness of the corresponding noise interference source is smaller. For example, the overhearing distance is 3 meters, and the sounding loudness of the corresponding noise interference source is 1E; the overhearing distance is 2 meters, and the sound production loudness of the corresponding noise interference source is 2E; the overhearing distance is 1 meter, and the sound production loudness of the corresponding noise interference source is 3E.
It should be noted that, in the exemplary embodiment, a maximum sounding loudness Em is preset, and when the interference strength of the target interference source is set, the interference strength (i.e., sounding loudness) is less than or equal to the maximum sounding strength Em, that is, the aforementioned interference strength of the target interference source does not exceed the preset maximum sounding strength Em, so as to ensure that a user in a call can hear clearly when receiving a voice uttered by the electronic device.
In an example embodiment, by using technologies such as voice recognition, when preset keywords such as "inaudible" appear in the call voice collected by the electronic device, the volume of the call voice sent by the electronic device is increased according to a preset value, or the sound production loudness of interference noise is reduced, so that it is ensured that a user in a call can hear clearly when receiving the voice sent by the electronic device.
In an example embodiment, the interference strength may also be adjusted using the number of listeners obtained in step 110 as an auxiliary variable. The more the number of the people listening beside the telephone, the interference intensity is enhanced, and the sounding volume of the receiver is increased according to a preset numerical value.
In step S130, the target interference source is played according to the set interference strength, so as to protect the call privacy of the user.
In an example embodiment, the electronic device sends the target interference source interference noise from the loudspeaker according to the set interference intensity, so that the requirement of comfort of a user in a call is met, and the listener can be interfered to not hear the voice sent by the handle of the electronic device, so that the call privacy of the user is protected.
In an exemplary embodiment, when the listening distance of the listener is greater than the safe calling distance after the listener moves, the playing of the interference noise is stopped, but the camera is kept periodically on to monitor the surrounding environment, so that the power consumption of the electronic device is saved.
According to the call privacy protection method in the exemplary embodiment of fig. 1, first, when a user makes a call through an electronic device, a secure call range corresponding to the user is determined, and an overhearing distance between a listener located within the secure call range and the user is acquired; then, according to the hearing distance, selecting a target interference source from a plurality of preset noise interference sources, and setting the interference intensity of the target interference source; and finally, playing the target interference source according to the set interference intensity so as to protect the conversation privacy of the user. According to the embodiment of the invention, the interference noise can be sent out according to the distance between the listener and the conversation user, so that the problem of privacy disclosure in the conversation process caused by the sound leakage phenomenon is solved, the risk of privacy disclosure in the conversation process is reduced, and the effect of protecting the conversation privacy is achieved.
Further, in the exemplary embodiment, based on the environment image, it is determined whether there is a suspicious eavesdropping behavior of a listener located within the secure call range; and if the suspicious interception behavior exists, sending a safety warning to the user. Specifically, an alert distance is preset by taking the electronic device in the call as a center, the alert distance is far smaller than the safe call distance, an alert range with the alert distance as a radius is further determined, and the alert range is far smaller than the safe call range. And analyzing the collected environment image, and judging whether the listeners in the warning range have suspicious eavesdropping behaviors. The environment image analysis may adopt technologies such as image extraction, feature analysis, image analysis, AI identification, and the like, and the embodiment of the present invention is not particularly limited thereto. Suspicious eavesdropping behavior includes, but is not limited to, the behavior of listeners slowly or abnormally close to the talker. If suspicious eavesdropping behavior exists, a high risk hidden danger that a bystander eavesdrops the privacy of a caller exists, and at the moment, the electronic equipment sends a safety warning to the caller, for example, a receiver of the electronic equipment sends a warning voice of 'beep' and a call interface of the electronic equipment has a safety prompting message 'attention to call information safety' and the like.
In an example embodiment, echo cancellation techniques are used to cancel noise emitted by a target interference source collected by a microphone of an electronic device. After the interference noise is emitted to the environment through the loudspeaker, the interference noise can be collected by a microphone of the mobile phone, and if the interference noise is emitted through the modem, the interference noise can be heard by the other party in the call. By adopting echo cancellation technology, the interference noise voice signal collected by the microphone of the mobile phone and the played interference noise signal are subjected to phase transformation, amplitude subtraction and other operations, so that the noise collected by the microphone is eliminated, and the two parties of the call are ensured not to be influenced by the noise.
Fig. 2 is another schematic flow chart of a call privacy protection method according to another embodiment of the present invention.
Referring to fig. 2, in step S210, mapping relationships between interference sources of different types and interference intensities according to distances are preset.
In an example embodiment, a mapping relationship of the distance to the noise interference source is preset; and presetting a mapping relation between the distance and the interference strength. For example, 3 meters corresponds to interference noise a, 2 meters corresponds to interference noise B, and 1 meter corresponds to interference noise C. The 3 m corresponds to the sounding loudness 1E, the 2 m corresponds to the sounding loudness 2E, and the 1 m corresponds to the sounding loudness 3E.
In step S220, the screen camera is periodically turned on during the handle call, the hearing distance between the other people and the caller and the safe call distance are obtained, and the number of hearing people within the safe call distance is recorded.
In an example embodiment, a safe communication distance is marked through big data, experiments and the like, a user who carries out communication by the handheld electronic device is taken as a center, and the safe communication distance is taken as a radius to determine a safe communication range. When a user uses a handle of a mobile phone to communicate, a screen camera is periodically started; and acquiring the hearing distance between the listener and the user based on the environment image acquired by the camera.
In an example embodiment, the number of listeners whose listening distance is less than the safe talk distance is counted as the number of listeners. The number of bystanders is applied in the subsequent step S270.
In step S230, it is determined whether the overhearing distance is less than the safe call distance.
In an exemplary embodiment, the auditing distance is compared with the safe communication distance to determine whether the auditing distance is less than the safe communication distance, if so, the process goes to step S240, and if not, the process goes to step S250.
In step S240, the interference source type and the interference intensity corresponding to the overhearing distance are selected.
In an exemplary embodiment, when the overhearing distance is smaller than the safe call distance, based on the mapping relationship between the distance preset in step S210 and the noise interference source, selecting an interference source type corresponding to the overhearing distance as a target interference source; and setting the interference intensity of the target interference source based on the preset mapping relation between the distance and the interference intensity in the step S210.
In step S250, the speaker is turned off and the playing of the interference source is stopped.
In an example embodiment, when the overhearing distance is not less than the safe talking distance, the speaker is turned off and no interference noise is emitted.
In step S260, the speaker is turned on, and the selected interference source emits sound from the speaker with the selected interference intensity.
In an example embodiment, the selected interferer, i.e., the target interferer, emits the target interferer from the speaker with the set interference strength.
In step S270, the number of listeners is used as an auxiliary variable, and the greater the number of listeners, the greater the interference strength, and the greater the receiver sound emission (the selected strength is less than the maximum sound emission strength).
In an example embodiment, the number of the bystanders acquired in step S240 is used as an auxiliary variable to adjust the interference intensity of the target interference source, the more the number of the bystanders, the greater the interference intensity, and the sound volume of the receiver is increased.
It is noted that in an example embodiment, the target interferer is set to an interference level less than a preset maximum voicing level.
In step S280, the echo cancellation technique cancels the interference noise collected by the microphone of the handset.
In an exemplary embodiment, the interference noise is picked up by the microphone of the handset after being emitted to the environment through the speaker. By adopting echo cancellation technology, the interference noise voice signal collected by the microphone of the mobile phone and the played interference noise signal are subjected to phase transformation, amplitude subtraction and other operations, so that the noise collected by the microphone is eliminated, and the two parties of the call are ensured not to be influenced by the noise.
In step S290, the modem transmits a call voice packet.
In an exemplary embodiment, the modem transmits a call voice packet, and a call partner of a user who calls with the mobile phone hears the voice with interference noise removed, and makes a normal call with the user.
