[0038] Figure 1 The diagram illustrates a system architecture of a data encryption method, data decryption method, apparatus, device, medium, and program product according to embodiments of the present disclosure.

[0039] like Figure 1 As shown, the system architecture 100 according to this embodiment may include a first server 101, a second server 102, a third server 103, and a network 104. The network 104 is used as a medium to provide a communication link between the first server 101, the second server 102, and the third server 103.

[0040] The first server 101, the second server 102, and the third server 103 can be servers that provide various services.

[0041] The first server 101 may be, for example, a server that generates and stores target data. The second server 102 may be, for example, a server that can obtain target data from the first server 101 and encrypt the target data. The third server 102 may be, for example, a server that receives fused encrypted data sent by the second server 102 and decrypts the fused encrypted data.

[0042] It should be noted that the data encryption method provided in this embodiment can generally be executed by the second server 102. Correspondingly, the data encryption device provided in this embodiment can generally be located in the second server 102. The data encryption method provided in this embodiment can also be executed by a server or server cluster that is different from the second server 102 and capable of communicating with the first server 101 and / or the third server 103.

Accordingly, the data decryption device provided in this embodiment of the present disclosure may also be set in a server or server cluster that is different from the third server 103 and is able to communicate with the first server 101 and / or the second server 102.

[0043] It should be understood that Figure 1 The number of first, second, and third servers shown is merely illustrative. Depending on implementation needs, there can be any number of first, second, and third servers.

[0044] The following will be based on Figure 1 The described scene, through Figures 2-7 The data encryption method of the present disclosure embodiments will be described in detail, through Figure 8 The data decryption method of the present disclosure embodiments will be described in detail.

[0045] Figure 2 A flowchart illustrating a data encryption method according to an embodiment of the present disclosure is shown schematically.

[0046] like Figure 2 As shown, the data encryption method 200 of this embodiment includes operations S210 to S230.

[0047] In operation S210, the target data is encrypted to obtain the initial encrypted data.

[0048] For example, the target data that needs to be encrypted can be predetermined. The target data could be, for example, business data.

[0049] For example, the target data can be encrypted using an encryption key to obtain the initial encrypted data.

[0050] In operation S220, the target audio data is determined from the reference audio data.

[0051] For example, reference audio data can be predetermined.

[0052] In operation S230, the initial encrypted data is fused with the target audio data to determine the fused encrypted data.

[0053] In operation S240, the target encrypted data is determined based on the reference audio data and the fused encrypted data.

[0054] For example, the target audio data in the reference audio data can be replaced with fused encrypted data to obtain the target encrypted data. It can be understood that the target encrypted data and the reference audio data are both audio data.

[0055] According to the data encryption method of this disclosure, after encrypting the target data to obtain initial encrypted data, target audio data is determined from reference audio data, and the initial encrypted data and the target audio data are fused. The determined fused encrypted data is similar to concealing the initial encrypted data, and has higher security than the initial encrypted data. Even when the target data is not in an audio format, since the target encrypted data determined from the reference audio data and the fused encrypted data is in an audio format, it is similar to a format conversion of the target data, also providing higher security.

[0056] It should be noted that the execution order of operation S210 and operation S220 can be interchanged.

[0057] Figure 3 A flowchart illustrating the determination of fused encrypted data according to another embodiment of the data encryption method of this disclosure is shown.

[0058] like Figure 3 As shown, for example, the operation S330 of fusing the initial encrypted data with the target audio data can be implemented using the following embodiment to determine a specific example of fusing the encrypted data.

[0059] In operation S331, a target audio segment is extracted from the target audio data to obtain the target audio segment audio data.

[0060] The target audio segment has the same length as the initial encrypted data.

[0061] In operation S332, the initial encrypted data and the target audio segment audio data are converted into binary data streams, resulting in the first data stream and the second data stream, respectively.

[0062] The operation S332, "converting the initial encrypted data and the target audio segment audio data into binary data streams to obtain the first data stream and the second data stream respectively," can be understood as: converting the initial encrypted data into a binary data stream to obtain the first data stream; and converting the target audio segment audio data into a binary data stream to obtain the second data stream.

[0063] If the target audio segment audio data has the same data length as the initial encrypted data, the first data stream and the second data stream also have the same data length.

[0064] In operation S333, the merged encrypted data is determined based on the first data stream and the second data stream.

[0065] According to the data encryption method of this disclosure, a target audio segment with the same data length as the initial encrypted data can be extracted from the target audio data. The target audio segment and the initial encrypted data are then converted into binary data streams. The identical data format (both the first and second data streams are binary data streams) and consistent data length facilitate the fusion of the first and second data streams to obtain fused encrypted data. Furthermore, when the fused encrypted data is determined using operations such as addition, subtraction, multiplication, and division, the binary data stream also facilitates computation.

[0066] For example, operations S331 to S333 can be performed after operation S220 or before operation S240. Operation S330 is similar to operation S230 and will not be described again here.

[0067] Figure 4 The flowchart illustrating the process of obtaining audio data of a target audio segment according to another embodiment of the data encryption method of the present disclosure is shown.

[0068] like Figure 4 As shown, for example, the specific example of how to extract a target audio segment from the target audio data to obtain the target audio segment audio data can be implemented using the following embodiment.

[0069] In operation S411, the corresponding target spectrogram is determined based on the target audio data.

[0070] For example, the Mel-Cepstral Coefficients of the target audio data can be determined based on the target audio data, and the corresponding Mel-Cepstral plot can be obtained as the target spectrogram.

[0071] Mel-scale frequency cepstral coefficients, or MFCCs for short, are used to determine parameters that exhibit better robustness, better match the auditory characteristics of the human ear, and maintain good recognition performance even when the signal-to-noise ratio decreases.

[0072] For example, this can be achieved through: pre-emphasis → framing → windowing → Fast Fourier Transform → triangular bandpass filter → Mel-frequency filter bank → calculating the logarithmic energy of each filter bank's output → obtaining MFCC via discrete cosine transform. Pre-emphasis can be implemented by passing the target speech data through a high-pass filter. Pre-emphasis can boost the high-frequency components, flattening the signal spectrum and maintaining the signal across the entire frequency band from low to high frequencies. Pre-emphasis can also eliminate the effects of the vocal cords and lips during phonation, compensating for the high-frequency components of the speech signal suppressed by the vocal system and highlighting high-frequency formants.

[0073] In operation S412, a target spectrum segment is extracted from the target spectrum map according to the extraction rules.

[0074] The truncation rule applies to at least one of the following: maximum and minimum amplitude, maximum and minimum amplitude increment, and average amplitude.

[0075] For example, when the truncation rule targets the maximum amplitude, the target spectrum segment can be truncated from the target spectrum with the maximum amplitude as the center, extending to both sides of the maximum amplitude.

[0076] For example, the maximum and minimum amplitude values ​​can include the maximum amplitude value and the minimum amplitude value, and the maximum amplitude value can be selected as the maximum amplitude value.

[0077] For example, when the truncation rule targets the maximum and minimum amplitude increment, the target spectrum segment can be truncated from the target spectrum with the maximum and minimum amplitude increment as the center position, extending to both sides of the maximum and minimum amplitude increment.

[0078] For example, the maximum and minimum amplitude increments can include the maximum amplitude increment (corresponding to the maximum slope) and the minimum amplitude increment (corresponding to the minimum slope). For instance, the maximum amplitude increment can be selected as the maximum amplitude increment.

[0079] For example, when the truncation rule is applied to the amplitude average, the target spectrum segment can be truncated from the target spectrum plot with the amplitude average as the center position, extending to both sides of the amplitude average.

[0080] In operation S413, the corresponding target audio segment audio data is determined based on the target spectrum segment.

[0081] According to the data encryption method of this disclosure, for target audio data, by determining the corresponding target spectrogram, the audio data can be converted into a spectral form that is easy to process. Furthermore, according to specific truncation rules, a target spectrum segment can be extracted from the target spectrogram. Compared to directly encrypting the target data to obtain initial encrypted data, this method adds the step of extracting a target spectrum segment from the target spectrogram according to truncation rules, which can improve data security. In addition, since the target audio segment is determined according to truncation rules, data security can be improved whether the truncation rules can be set or agreed upon only by the data sender and data receiver.

[0082] For example, operations S411 to S413 can be performed before operation S332. Operation S410 is similar to operation S331 and will not be described again here.

[0083] Figure 5 The flowchart illustrating the determination of fused encrypted data in a data encryption method according to yet another embodiment of the present disclosure is shown.

[0084] like Figure 5 As shown, for example, the specific example of determining the fused encrypted data based on the first data stream and the second data stream in operation S530 can be implemented using the following embodiment.

[0085] In operation S531, according to the fusion rules, the first data stream and the second data stream are fused to obtain fused encrypted data.

[0086] The fusion rules include at least one of the following: operation rules, replacement rules, and addition / deletion rules.

[0087] For example, the operation rule can represent the rule of performing operations such as addition, subtraction, multiplication, and division on the first data stream and the second data stream; the replacement rule can represent the rule of replacing values ​​on the first data stream and the second data stream; and the addition / deletion rule can represent the rule of adding or deleting values ​​on the first data stream and the second data stream.

[0088] According to the data encryption method of this disclosure, a first data stream and a second data stream can be merged according to fusion rules to obtain merged encrypted data. Compared with directly encrypting the target data to obtain initial encrypted data, the method adds a step of merging the first data stream and the second data stream according to fusion rules, which can improve data security. In addition, since the merged encrypted data is determined according to fusion rules, data security can be improved whether the fusion rules can be set or agreed upon only by the data sender and the data receiver.

[0089] For example, operation S531 can be performed after operation S332. Operation S530 is similar to operation S333 and will not be described again here.

[0090] Figure 6 The flowchart illustrating the determination of target audio data in a data encryption method according to yet another embodiment of the present disclosure is shown schematically.

[0091] like Figure 6 As shown, for example, the specific example of determining target audio data from reference audio data in operation S620 can be implemented using the following embodiment.

[0092] The reference audio data has at least one audio track, and the target audio data has at least one target audio track.

[0093] For example, the reference audio data may have multiple audio tracks, and the target audio data may have one target audio track.

[0094] For example, when the target audio data has multiple target audio tracks, the multiple target audio tracks can be superimposed to make the multiple target audio tracks become a single audio track.

[0095] For example, when the target audio track data has multiple target audio tracks, a spectrogram corresponding to each target audio track can be obtained, and a portion can be extracted from the spectrogram corresponding to each target audio track. The extracted portions can then be spliced ​​together to obtain the target spectrum segment.

[0096] In operation S621, for each track of the reference audio data, the corresponding track selection evaluation value is determined based on the track selection parameters.

[0097] An audio track can be understood as a track containing audio information. Each audio track has specific audio attributes, such as different timbres.

[0098] In operation S622, the target audio track is determined from multiple audio tracks of the reference audio data based on the audio track selection evaluation value, and the target audio data is obtained.

[0099] According to the data encryption method of this disclosure, a specific target audio data can be determined from the reference audio data based on the audio tracks of the reference audio data and the target audio data. When the reference audio data includes multiple audio tracks and the target audio data corresponds to some of the audio tracks, an additional step is added to identify the audio track where the target audio data is located from the multiple audio tracks, which can improve data security.

[0100] For example, operations S621 to S622 can be performed before operation S230. Operation S620 is similar to operation S220 and will not be described again here.

[0101] According to another embodiment of the data encryption method of this disclosure, the audio track selection parameters include pitch.

[0102] For example, the following embodiment can be used to determine the corresponding track selection evaluation value for each track of the reference audio data based on the track selection parameters: Segment each track of the reference audio data to obtain multiple track segments; detect the pitch of each track segment to obtain the target track segment, which has a target pitch; determine the track selection evaluation value for each track based on the number of target track segments for each track.

[0103] Each audio track segment has an initial pitch evaluation value. For example, the initial pitch evaluation value can be set to 0.

[0104] For example, each track of the reference audio can be segmented over a predetermined time period to obtain multiple track segments.

[0105] For example, the target pitch can be predetermined, or the target pitch can be determined by sorting the pitches after detecting the pitch of each audio track segment, and using the pitch value ranked in the nth position as the target pitch.

[0106] For example, the value of the target audio track segment can be determined based on the number of timestamps that reach the target pitch.

[0107] For example, for each audio track, the track selection evaluation value can be calculated by multiplying the number of target audio tracks by a certain numerical value.

[0108] According to the data encryption method of this disclosure, the pitch parameter of the audio can be used as the basis for selecting the target audio track, making full use of the audio parameters and improving the security of data encryption.

[0109] For example, the track selection evaluation values ​​of each audio track can be sorted, and the audio tracks with the highest track selection evaluation values ​​among the multiple audio tracks of the reference audio data can be identified as the target audio data.

[0110] For example, other parameters such as frequency can also be used as the basis for selecting the target audio track, which will not be elaborated here.

[0111] Figure 7 A flowchart illustrating a data encryption method according to yet another embodiment of the present disclosure is shown.

[0112] like Figure 7 As shown, the data encryption method 700 according to another embodiment of the present disclosure may include, for example, operations S750 to S760.

[0113] In operation S750, at least one target mono audio track is determined from the mono audio track data set.

[0114] A mono audio data set includes at least one mono audio track. Each mono audio track consists of audio data from a single track.

[0115] For example, a set of single-track audio data can be predetermined. This set of single-track audio data can also be updated periodically by relevant personnel.

[0116] During operation of S760, at least one target mono audio track is fused to obtain reference audio data.

[0117] For example, at least one target monotrack audio data can be superimposed to obtain reference audio data.

[0118] According to the data encryption method of this disclosure, at least one target monophonic audio data can be determined from a monophonic audio data set to obtain reference audio data. The reference audio data, as part of the fusion with the initial encrypted data, adds the step of determining the reference audio data based on the monophonic audio data set, which can also improve data security.

[0119] In summary, the data encryption method according to the embodiments of this disclosure, compared with the prior art of encrypting target data to obtain initial encrypted data, adds a step of fusing the initial encrypted data with the target audio data. Furthermore, it considers the characteristics of the audio format, using audio tracks as the basis for fusion, and extracts a specific audio segment according to truncation rules. Based on this, it performs fusion according to specific fusion rules to obtain fused encrypted data. Regarding the step of obtaining the target audio data, each audio track of the reference audio data is evaluated according to audio track selection parameters. The obtained audio track selection evaluation value can be used to determine the target audio track from multiple audio tracks of the reference audio data, thus obtaining the target audio data. Regarding the step of obtaining the reference audio data, at least one target single-track audio data can be determined based on the single-track audio data set and fused to obtain the reference audio data. All of the above-mentioned added steps can improve data security. In some steps, such as truncation rules and fusion rules, they can be set according to needs or agreed upon by the data sender and data receiver, thereby improving data security.

[0120] This disclosure also provides a data decryption method.

[0121] Figure 8 A flowchart of a data decryption method 800 according to an embodiment of the present disclosure is illustrated schematically.

[0122] like Figure 8 As shown, the data decryption method 800 according to an embodiment of this disclosure includes operations S810 to S830.

[0123] The S810 is in operation, receiving target encrypted data.

[0124] The target encrypted data is obtained by the data encryption method described in the above embodiments.

[0125] The S820 is used to parse the target encrypted data and obtain the initial encrypted data.

[0126] It is understood that the parsing rules for the target encrypted data correspond to the process of obtaining the target encrypted data from the initial encrypted data in the data encryption method of the above embodiments. For example, the parsing rules include the above-mentioned fusion rules, truncation rules, etc., which will not be elaborated here.

[0127] The S830 is used to decrypt the initial encrypted data to obtain the target data.

[0128] Since the target encrypted data has higher data security, the data decryption method according to the embodiments of this disclosure can also improve data security by parsing the target encrypted data and matching it with the above-mentioned data encryption process after receiving the target encrypted data.

[0129] It should be noted that the data encryption and decryption methods according to the embodiments of this disclosure can be applied to financial industries such as banking, and the target data can be important business data or transaction data. The data encryption and decryption methods according to the embodiments of this disclosure can improve data security.

[0130] For example, taking the target data as business data, the data decryption method according to the embodiments of this disclosure can perform business logic processing on the obtained target data if the data decryption is successful, and record the decryption failure or reject subsequent processing if the data decryption fails, thereby strengthening data security supervision and improving data security.

[0131] Based on the above data encryption method, this disclosure also provides a data encryption device. The following will be combined with... Figure 9 The device is described in detail.

[0132] Figure 9 A schematic block diagram of a data encryption device according to an embodiment of the present disclosure is shown.

[0133] like Figure 9 As shown, the data encryption device 900 of this embodiment includes an initial encrypted data determination module 910, a target audio data determination module 920, a fused encrypted data determination module 930, and a fused encrypted data determination module 940.

[0134] The initial encrypted data determination module 910 is used to encrypt the target data to obtain the initial encrypted data.

[0135] The target audio data determination module 920 is used to determine the target audio data from the reference audio data.

[0136] The fused encrypted data determination module 930 is used to fuse the initial encrypted data with the target audio data to determine the fused encrypted data.
