Therefore, the disclosure of the embodiments of the present specification can be embodied in the following forms: entirely hardware, entirely software (including firmware, resident software, micro-code, etc.), or a combination of hardware and software.
Although the flow described below includes operations that occur in a particular order, it should be appreciated that the processes may include more or less operations that are performed sequentially or in parallel (e.g., using parallel processors or a multi-threaded environment).
As shown in fig. 1, which is a schematic view of a scenario of an information processing system provided in this specification, the information processing system may include: a terminal device 101 and a server 102. In particular, the client may initiate an information processing request to the terminal device 101. After receiving the information processing request, the terminal device 101 may acquire the verification video and the privacy information input by the client, extract the audio track information from the verification video, and determine the spectrum data of the privacy information. Further, the spectrum data may be written into the audio track information, a target verification video is obtained, and the target verification video is transmitted to the server 102. Upon receiving the target verification video, the server 102 may extract the audio track information from the target verification video. Then, spectrum data corresponding to the audio track information may be obtained, and the spectrum data is analyzed to obtain privacy information included in the target verification video. In the information processing process, the privacy information is transmitted by combining the audio frequency domain steganography technology, so that even if the verification information is intercepted in the information transmission process, the password trace cannot be seen due to the absence of the password field, the privacy of the client can be effectively protected, and the privacy safety of the client is greatly guaranteed.
The terminal device 101 may be a terminal device or software used for a client operation. Specifically, the terminal device may be a terminal device such as a smart phone, a tablet computer, a notebook computer, a desktop computer, a smart watch, or other wearable devices, or may be a robot device.

The server 102 may be a single server or a server cluster, and certainly, the functions of the server may also be implemented by a cloud computing technology. The server 102 may be connected to a plurality of terminal devices, or may be a server having a powerful information repository.
The following describes an embodiment of the present disclosure with a specific application scenario as an example. Specifically, fig. 2 is a schematic flowchart of an embodiment of an information processing method provided in this specification. Although the present specification provides the method steps or apparatus structures as shown in the following examples or figures, more or less steps or modules may be included in the method or apparatus structures based on conventional or non-inventive efforts.
It should be noted that, in the technical solution of the present application, the acquisition, storage, use, processing, etc. of data all conform to the relevant regulations of the national laws and regulations. The following embodiments are described from the perspective of a terminal device, and do not limit other technical solutions in the extensible application scenario based on the present specification. Specifically, as shown in fig. 2, an information processing method provided in the present specification may include the following steps.
S20: and acquiring the verification video and the privacy information input by the client.
The verification video may be a lip language identification video, and may also be other videos used for verification, which is not limited in this specification. Audio track information may be included in the verification video. Private information may also be referred to as sensitive information. Some sensitive characters, such as passwords, identification marks, etc., may be included in the private information.
In some embodiments, the terminal device may prompt the customer to record a verification video and then obtain the verification video entered by the customer. In other embodiments, the terminal device may obtain the verification video prerecorded by the client from the local, and may also obtain the verification video prerecorded by the client from a third-party organization, which is not limited in this specification. Wherein the third party authority may be a device communicating with the terminal device.
In some embodiments, the client may enter the private information based on a prompt from the terminal device. The client can input the privacy information in the modes of voice, keyboard, touch screen, card swiping and the like. In some implementation scenarios, if the user inputs the private information in a voice manner, the private information can be converted into a text form after being acquired, which is convenient for subsequent processing.
S22: extracting audio track information from the verification video.
In the embodiment of the present specification, after the verification video input by the client is acquired, the audio track information may be extracted from the verification video. The tracks can be understood as parallel "tracks" of one strip as seen in sequencer software. The soundtrack information may be understood as an audio file extracted from the verification video. One or more audio tracks may be extracted from the verification video, each corresponding to audio track information. The track information for each track may include attributes of the track such as the timbre, the timbre library, the number of channels, the input/output ports, the volume, etc. of the track.
In some embodiments, pre-set software may be utilized to extract the soundtrack information from the verification video. Therein, preset software may be used to extract tracks from the video, for example, racoon track extraction software, authacy, etc. Audacity is a free piece of audio processing software. Of course, the above description is only exemplary, and the way of extracting the audio track information from the verification video is not limited to the above examples, and other modifications are possible for those skilled in the art in light of the technical spirit of the present application, but all that can be achieved by the method and the device are covered by the scope of the present application as long as the functions and effects are the same as or similar to those of the present application.
S24: and determining the spectrum data of the privacy information.
In this embodiment of the present specification, after obtaining the private information input by the client, spectrum data of the private information may be determined.
In some embodiments, determining the spectrum data of the private information may include: calculating a hash value of the private information; determining frequency spectrum data corresponding to each character in the hash value; and determining the spectrum data of the privacy information based on the spectrum data corresponding to each character in the hash value.
In some embodiments, the determining the spectrum data corresponding to each character in the hash value may include: acquiring a preset character set from a block chain; the preset character set comprises a corresponding relation between characters and frequency spectrum data; and determining the frequency spectrum data corresponding to each character in the hash value according to the corresponding relation between the character and the frequency spectrum data. The blockchain is a decentralized, non-falsifiable and credible distributed account book and has the characteristics of non-falsification, whole-course trace retention, traceability, public transparency, collective maintenance and the like.
Specifically, for example, in some implementation scenarios, a large number of characters may be collected first, spectrum data corresponding to each character may be determined, then a preset character set may be generated according to a correspondence between the characters and the spectrum data, and finally, the collected characters and the preset character set may be stored in a block chain for subsequent query.
Further, after the private information input by the client is obtained, a hash value of the private information can be calculated, then characters corresponding to the hash value are inquired in the block chain, and then, according to a preset character set, spectrum data corresponding to each character in the hash value is determined, so that the spectrum data corresponding to the private information is determined.
In some embodiments, after obtaining the hash value of the private information, the hash value of the private information may also be stored in the blockchain for subsequent verification, thereby improving data security.
In the embodiment of the specification, the block chain is used for storing the character spectrum data, the hash value and the like, so that tampering can be prevented, and the security is improved.
S26: and writing the frequency spectrum data into the audio track information to obtain a target verification video.
In this embodiment of the present specification, after extracting audio track information from a verification video and determining spectrum data of privacy information, the spectrum data may be steganographically written into the audio track information to obtain a target verification video. Wherein the target verification video may be understood as a video to be transmitted to the target system. Sensitive information of a client is hidden in the target verification video. When the target verification video is intercepted, the password field is not displayed, and only one common data packet for transmitting the video is displayed. Steganography is a way of hiding information, which is understood to be the delivery of events or content of information that do not let anyone other than the intended recipient know the information.
In some embodiments, writing the spectrum data into the audio track information to obtain a target verification video may include: acquiring a spectrogram corresponding to the audio track information; writing the frequency spectrum data of the privacy information into the frequency spectrum graph to obtain a target frequency spectrum graph; and obtaining a target verification video according to the target spectrogram. The spectrogram of an audio file can be understood as a graph describing the frequency and energy of a signal. Visible characters or patterns can be formed by modifying the spectrogram of the audio file, the influence of the modification result on the audio file is very weak, and people cannot recognize information on the spectrogram only by playing the audio file.
S28: and transmitting the target verification video to a target system.
In this embodiment of the present description, after a target verification video is obtained, the target verification video may be uploaded to a target system. The target system can be a background system, a server and the like.
In some embodiments, the manner of transmitting the target verification video to the target system may be one or more of wired, wireless, and the like, which is not limited in this specification.
In some embodiments, the target system may extract audio track information from the target verification video after obtaining the target verification video. Further, spectrum data corresponding to the audio track information can be obtained, the spectrum data are analyzed, privacy information included in the target verification video is obtained, and therefore secret transmission of the sensitive information is completed.
The embodiment of the specification can transmit the sensitive information of the client in a concealed mode when the verification video is transmitted, and even if the sensitive information is intercepted, the sensitive information such as the password input by the client is difficult to obtain.
The embodiment of the specification can be applied to the fields of finance, information transmission and the like. For example, a spectrogram of an audio file may be used to hide sensitive information transmissions in a financial transaction scenario.
In the embodiment of the specification, the hash value corresponding to the private information is stored by using the block chain, and multiple times of verification are performed, so that data can be effectively prevented from being tampered, and the data security is improved.
In the embodiment of the specification, the privacy information is transmitted by combining an OCR technology with an audio frequency domain steganography technology, so that if the transmitted information is intercepted, the transmitted information is unknown due to the fact that no password field exists, the security of the transmitted information can be improved, and the privacy of a client can be effectively protected.
It is to be understood that the foregoing is only exemplary, and the embodiments of the present disclosure are not limited to the above examples, and other modifications may be made by those skilled in the art within the spirit of the present disclosure, and the scope of the present disclosure is intended to be covered by the claims as long as the functions and effects achieved by the embodiments are the same as or similar to the present disclosure.
The above embodiments describe the implementation of the information processing method from the terminal device perspective. Based on the description of the above embodiments, the present specification also provides an information processing method described from the server perspective. Fig. 3 is a schematic flow chart of an embodiment of another information processing method provided in this specification. Specifically, in one embodiment, the method may include the following steps.
S30: receiving a target verification video; the target verification video is obtained according to the verification video and the privacy information input by the client;
s32: extracting audio track information from the target verification video;
s34: acquiring frequency spectrum data corresponding to the audio track information;
s36: and analyzing the frequency spectrum data to obtain privacy information included in the target verification video.
The target verification video may be obtained based on the foregoing steps S20-S26, which are not described herein again. The way of extracting the audio track information from the target verification video is similar to the way of extracting the audio track information from the verification video in step S22, and may refer to each other, which is not described herein again.
In some embodiments, after extracting the audio track information from the target verification video, the spectral data corresponding to the audio track information may be obtained. The spectral data corresponding to the audio track information may be understood as a spectrogram corresponding to the audio track information.
In some embodiments, the analyzing the spectrum data to obtain the privacy information included in the target verification video may include: analyzing the spectrum data by using an OCR technology to obtain a hash value corresponding to the privacy information; and obtaining privacy information according to the hash value. Among them, OCR (Optical Character Recognition) refers to a process in which an electronic device (e.g., a scanner or a digital camera) checks a Character printed on paper, determines its shape by detecting dark and light patterns, and then translates the shape into a computer text by a Character Recognition method.
For example, in some implementation scenarios, after obtaining a spectrogram corresponding to audio track information, the spectrogram may be analyzed by using an OCR technique to obtain a hash value of sensitive information hidden in the spectrogram. Further, the hidden sensitive information in the spectrogram can be determined according to the hash value.
In some embodiments, after the hash value corresponding to the privacy information is obtained, it may be further determined whether the hash value corresponding to the privacy information exists in the block chain, and in the presence, a service transaction may be performed. In some implementation scenarios, if the hash value corresponding to the private information does not exist in the blockchain, it indicates that the data is tampered, and at this time, the service transaction may be denied.
Specifically, for example, after the lip language verification video is sent to the background system, the background system may extract the audio track information, analyze a spectrogram corresponding to the audio track information by using an OCR technology, and obtain a hash value of the sensitive information. Further, the obtained hash value may be compared with the hash values stored in the block chain, and if the results are consistent, the service processing is performed, and if the results are inconsistent, it is described that the data is tampered, and at this time, the service transaction may be rejected.
It should be noted that, in the present specification, each embodiment of the method is described in a progressive manner, and the same and similar parts among the embodiments are referred to each other, and each embodiment focuses on the differences from other embodiments. For the relevant points, reference may be made to some descriptions of other method embodiments, which are not described in detail herein.
From the above description, it can be seen that, in the embodiment of the application, the verification video and the privacy information input by the client can be obtained, the audio track information is extracted from the verification video, and the spectrum data of the privacy information is determined; the frequency spectrum data can be written into the audio track information to obtain a target verification video, and the target verification video is transmitted to a target system. In the information processing process, the privacy information is transmitted by combining the audio frequency domain steganography technology, so that even if the verification information is intercepted in the information transmission process, the password trace cannot be seen due to the absence of the password field, the privacy of the client can be effectively protected, and the privacy safety of the client is greatly guaranteed.
It is to be understood that the foregoing is only exemplary, and the embodiments of the present disclosure are not limited to the above examples, and other modifications may be made by those skilled in the art within the spirit of the present disclosure, and the scope of the present disclosure is intended to be covered by the claims as long as the functions and effects achieved by the embodiments are the same as or similar to the present disclosure.
