[0058] To make the objectives, technical solutions, and advantages of this application clearer, the following detailed description is provided in conjunction with the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are merely illustrative and not intended to limit the scope of this application.

[0059] The electrocardiogram (ECG) data processing method provided in this application embodiment can be applied to, for example... Figure 1In the application environment shown, after the ECG signal acquisition device 102 acquires the target ECG data of the target object, the ECG signal acquisition box can, in response to the storage command for the target ECG data, determine interference indication information for the target ECG data; then, the ECG signal acquisition device 102 can perform interference processing on the target ECG data according to the interference method represented by the interference indication information to obtain the interfered ECG data; then, the ECG signal acquisition device 102 encrypts the interference indication information to obtain a key segment that matches the interfered ECG data; the ECG signal acquisition device 102 stores the interfered ECG data and the key segment in the storage device 104; the key segment is used to restore the interfered ECG data to the target ECG data. In practical applications, the storage device 104 can be, but is not limited to, various computer-readable storage media such as SD cards, USB flash drives, and portable hard drives. The ECG signal acquisition device 102 can refer to the ECG signal acquisition box.

[0060] In one embodiment, such as Figure 2 As shown, an electrocardiogram (ECG) data processing method is provided, which can be applied to... Figure 1 The following steps are used as an example to illustrate the process of acquiring electrocardiogram (ECG) signals: 102.

[0061] Step 202: In response to the instruction to store the target ECG data, determine interference indication information for the target ECG data.

[0062] The target ECG data can refer to the ECG signal data that needs to be stored.

[0063] Interference indication information refers to the data interference method applied to the target ECG data. In practical applications, data interference methods may include, but are not limited to, adding noisy data, adjusting the data storage method, and deleting target data.

[0064] In practice, when the ECG signal acquisition device acquires the ECG signal data of the target object (e.g., the human body) (i.e., the target ECG data), the ECG signal acquisition device can respond to the storage instruction for the target ECG data and randomly determine the interference indication information for the target ECG data, so as to perform interference processing on the target ECG data according to the interference indication information in the future.

[0065] For example, in response to a command to store the target ECG data, the ECG signal acquisition device can randomly generate interference indication information that represents at least one type of interference. The interference indication information may include information such as the addition location, noise type, and noise length of the noise data to be added to the target ECG data.

[0066] Step 204: According to the interference mode represented by the interference indication information, the target ECG data is subjected to interference processing to obtain the interfered ECG data.

[0067] In practice, during the process of interfering with the target ECG data according to the interference mode characterized by the interference indication information, the ECG signal acquisition device can generate target noise data according to information such as noise type and noise length, and add the target noise data to the target ECG data at the addition position indicated by the interference indication information, so as to achieve interference processing of the target ECG data and obtain the interfered ECG data.

[0068] Step 206: Encrypt the interference indication information to obtain a key segment that matches the ECG data after interference.

[0069] In practice, the ECG signal acquisition device can also use a preset encryption algorithm to encrypt the interference indication information and obtain the encryption result; the ECG signal acquisition device then generates a key segment that matches the interfered ECG data based on the encryption result.

[0070] Step 208: Store the ECG data and key segment after interference.

[0071] In practice, after determining the interfered ECG data and key segment, the ECG signal acquisition device can store the interfered ECG data and key segment. Specifically, the ECG signal acquisition device can store the interfered ECG data and key segment to a computer-readable storage medium (such as an SD card, USB flash drive, or external hard drive) electrically connected to the ECG signal acquisition device.

[0072] Of course, the ECG signal acquisition device can also store the interfered ECG data and the key segment separately on different storage devices, thereby enabling data control over the key segment. The key segment is used to restore the interfered ECG data to the target ECG data.

[0073] When a user needs to analyze the electrocardiogram (ECG) signal data of the target object, the user can use the ECG signal analysis software installed on the electronic device to read and parse the ECG data stored in the readable storage medium. In other words, the electronic device can restore the ECG data after interference to the target ECG data.

[0074] Specifically, the electronic device can decrypt the key segment using the decryption algorithm corresponding to the encryption algorithm mentioned above to obtain interference indication information. The electronic device then performs interference cancellation processing on the interfered ECG data according to the interference cancellation method corresponding to the interference mode represented by the interference indication information, thereby restoring the interfered ECG data to the target ECG data.

[0075] In the above-described ECG data processing method, in response to a storage instruction for the target ECG data, interference indication information for the target ECG data is determined. The target ECG data is then subjected to interference processing according to the interference method represented by the interference indication information to obtain interfered ECG data. The interference indication information is then encrypted to obtain a key segment matching the interfered ECG data. The interfered ECG data and the key segment are then stored. After the key segment is decrypted, it is used to restore the interfered ECG data to the target ECG data. Thus, by interfering with the target ECG data using an interference method, and subsequently restoring the interfered ECG data based on the corresponding descrambling method, and encrypting the interference method, the information carried by the target ECG data is effectively hidden in a reversible manner. This allows the ECG signal acquisition box to effectively encrypt the ECG signal data, avoiding the problem of insufficient computing power when encrypting ECG signal data, thereby effectively improving the processing efficiency of the ECG signal acquisition box.

[0076] Random generation algorithm for interference:

[0077] The master heartbeat stores common ECG interference signals in multiple segments. A random algorithm extracts different signal segments by random frequency (interval point values) and amplitude (data is magnified or reduced by a factor) (within an encrypted interval, the type of interference signal, the value of the interval point, and the amplitude change value are fixed).

[0078] In another embodiment, the target ECG data is subjected to interference processing according to the interference mode characterized by the interference indication information to obtain the interfered ECG data, including: generating interference data that meets the interference data length; adding the interference data to the target ECG data according to the interference data position to obtain the interfered ECG data.

[0079] The interference indication information includes the length and location of the interference data.

[0080] The interference data length can refer to the length of the interference data to be added to the target ECG data. In practical applications, the interference data length can also be named the interference duration length.

[0081] The interference data location can refer to the target insertion location corresponding to the interference data to be added to the target ECG data. In practical applications, the interference data location can also be named the interference insertion location.

[0082] In practice, the ECG signal acquisition device performs interference processing on the target ECG data according to the interference mode characterized by the interference indication information to obtain the interfered ECG data. Please refer to [link to relevant documentation]. Figure 3 , Figure 3A data encryption logic diagram for an electrocardiogram (ECG) data processing method is provided; the ECG signal acquisition device can use a preset interference method random generation algorithm to randomly generate the length and position of the interference data to be inserted into the target ECG data.

[0083] After determining the length of the interference data, the ECG signal acquisition device can randomly generate interference data with a length that meets the interference data length according to a preset data random generation algorithm.

[0084] In practical applications, the data similarity between the interference data randomly generated by the ECG signal acquisition device and the target ECG data can be greater than or equal to a preset similarity threshold. This data similarity can include, but is not limited to, at least one of data content similarity, data structure similarity, and data format similarity. This increases the difficulty of identifying the interference data from the interfered ECG data, thereby increasing the difficulty of cracking or tampering with the interfered ECG data.

[0085] In practical applications, the main control chip of the ECG signal acquisition device can store multiple common ECG interference signals. The ECG signal acquisition device can extract these different ECG interference signals according to random frequency (interval point values), random amplitude (data amplified or reduced by a factor), and fixed interference signal type, interval point values, and amplitude variation values ​​within an encrypted interval. This allows the generation of interference data with a data similarity to the target ECG data that meets preset conditions. It should be noted that the process of the ECG signal acquisition device generating interference data that meets the required length will be explained in detail below, but will not be elaborated on here. After generating the interference data, the ECG signal acquisition device adds the interference data to the target ECG data according to the interference data position, obtaining the interfered ECG data. Simultaneously, after obtaining the interfered ECG data, the ECG signal acquisition device can also detect whether the data length of the interfered ECG data is greater than or equal to a preset data length threshold. If the data length of the interfered ECG data is less than the preset data length threshold, the ECG signal acquisition device will use the interfered ECG data as the new target ECG data and re-execute the preset interference method random generation algorithm to randomly generate the interference data length and interference data position corresponding to the interference data to be inserted into the target ECG data. According to the preset data random generation algorithm, interference data with a data length that meets the interference data length is randomly generated. According to the interference data position, the interference data is added to the target ECG data to obtain the interfered ECG data. The above loop process is repeated until the interfered ECG data is greater than or equal to the preset data length threshold.

[0086] The ECG signal acquisition device can also use a preset encryption algorithm to encrypt the two numbers, the length and location of the interference data, and store the encrypted key (i.e., key segment) and the interfered ECG data in a storage device (e.g., SD).

[0087] The target ECG data includes at least two bytes. According to the location of the interference data, the interference data is added to the target ECG data to obtain the interference-free ECG data. This includes: determining the target addition position of the interference data in the interval between each two adjacent bytes in the target ECG data according to the location of the interference data; adding the interference data to the target addition position to obtain the interference-free ECG data.

[0088] For the convenience of those skilled in the art, Figure 4 An exemplary storage structure diagram of an electrocardiogram (ECG) data processing method is provided; wherein, 410 is a key segment, which carries the length and location of the encrypted interference data. 420 is the interference-prevented ECG data, which includes multiple bytes, each byte having a corresponding byte number; as shown... Figure 4 The interference data randomly generated by the ECG signal acquisition device is located between bytes 3 and 4 of the target ECG data, and between bytes 13 and 14 of the target ECG data. After generating interference data that meets the required length, the ECG signal acquisition device inserts this interference data into the positions between bytes 3 and 4 of the target ECG data, and between bytes 13 and 14 of the target ECG data, resulting in the interfered ECG data 420.

[0089] The technical solution of this embodiment includes interference indication information including interference data length and interference data position. By generating interference data that meets the interference data length and adding the interference data to the target ECG data according to the interference data position, interference ECG data is obtained. This effectively hides the information carried by the target ECG data in a reversible manner, thereby achieving effective encryption and decryption of the target ECG data without using complex encryption algorithms to encrypt the target ECG data as a whole.

[0090] In another embodiment, generating interference data that meets the interference data length includes: using a preset random number generation algorithm to generate a random number segment that meets the interference data length; determining the random number segment as interference data; and further obtaining the signal frequency corresponding to the ECG signal represented by the target ECG data; generating QRS waveform data of the corresponding period based on the signal frequency corresponding to the ECG signal; the data length of the QRS waveform data meets the interference data length; and determining the QRS waveform data as interference data.

[0091] In practical implementation, during the generation of interference data that meets the required length, the ECG signal acquisition device can employ a preset random number generation algorithm to generate random number segments that meet the required length. In actual applications, the ECG signal acquisition device can obtain the current value corresponding to random events such as the current time as a seed for random number generation, and use this seed to generate random number segments that meet the required length for interference data, which will then be added to the target ECG data.

[0092] Of course, the ECG signal acquisition device can also acquire the signal frequency corresponding to the ECG signal represented by the target ECG data, and generate QRS waveform data of the corresponding period based on the signal frequency, with the data length of the QRS waveform data meeting the interference data length. Then, the ECG signal acquisition device uses the QRS waveform data as interference data to be added to the target ECG data. In this way, the similarity between the interfered ECG data and the target ECG data can be effectively increased, increasing the difficulty of deciphering the interfered ECG data.

[0093] In another embodiment, the target ECG data includes at least two bytes, and the interference indication information also includes the storage order of each byte. The target ECG data is subjected to interference processing according to the interference method characterized by the interference indication information to obtain the interfered ECG data, including: adjusting the storage order of each byte in the target ECG data according to the storage order to obtain the interfered ECG data.

[0094] In practical implementation, during the process of determining interference indication information for the target ECG data, the ECG signal acquisition device can randomly generate a storage order for each byte and adjust the storage order of each byte in the target ECG data according to the storage order to obtain the interfered ECG data. Alternatively, the ECG signal acquisition device can directly store each byte of the target ECG data into the storage device according to the storage order to obtain the interfered ECG data. Please refer to [link to relevant documentation]. Figure 5 , Figure 5 A schematic diagram of the storage structure for another ECG data processing method is provided. The target ECG data 420 is known to consist of bytes 1, 2…15, 16 in sequence. The storage order randomly generated by the ECG signal acquisition device is (3,6,7,8…9,2,1). Therefore, the interfered ECG data 330 is composed of bytes 3, 6, 7, 8…9, 2, 1 in sequence. The ECG signal acquisition device encrypts the storage order, obtaining a key segment 410 carrying the encrypted storage order.

[0095] The technical solution of this embodiment adjusts the storage order of each byte in the target ECG data according to the storage order, thereby realizing the reversible hiding of the information carried by the target ECG data. This achieves effective encryption of the target ECG data without the need for complex encryption algorithms to encrypt the entire target ECG data.

[0096] In one embodiment, such as Figure 6 As shown, an electrocardiogram (ECG) data processing method is provided, which includes the following steps:

[0097] Step 602: In response to the instruction to restore the stored ECG data, read the stored ECG data and the key segment that matches the stored ECG data.

[0098] In practice, when a user needs to analyze the electrocardiogram (ECG) signal data of the target object, the ECG signal analysis software of the electronic device can respond to the recovery command of the stored ECG data stored in the SD card, read the stored ECG data stored in the SD card, and the key segment that matches the stored ECG data.

[0099] It should be noted that the process of generating stored ECG data and the key segment that matches the stored ECG data can be found in the specific limitations of the process of generating interfered ECG data and the key segment that matches the interfered ECG data mentioned above, and will not be repeated here.

[0100] Specifically, the electronic device can decrypt the key segment using the decryption algorithm corresponding to the encryption algorithm mentioned above to obtain interference indication information. The electronic device then performs interference cancellation processing on the interfered ECG data according to the interference cancellation method corresponding to the interference mode represented by the interference indication information, thereby restoring the interfered ECG data to the target ECG data.

[0101] Step 604: Decrypt the key segment that matches the stored ECG data to obtain the interference indication information corresponding to the stored ECG data; the interference indication information is used to characterize the interference method implemented on the stored ECG data.

[0102] In practice, once the electronic device reads a key segment matching the stored ECG data, it can decrypt that key segment to obtain interference indication information corresponding to the stored ECG data. This interference indication information characterizes the interference method applied to the stored ECG data. Specifically, the interference indication information can indicate that the stored ECG data involves adding interference data of a specific length to a specific position in the original ECG data.

[0103] Step 606: Perform interference cancellation processing on the stored ECG data according to the interference cancellation method corresponding to the interference method to obtain the recovered ECG data.

[0104] Among them, the interference cancellation method and the interference method are mutually derived.

[0105] In practice, once the electronic device determines the interference mode represented by the interference indication information, it can deduce the corresponding interference cancellation method.

[0106] For example, see Figure 7 , Figure 7 A data decryption logic diagram for an electrocardiogram (ECG) data processing method is provided. When the interference indication information indicates that the stored ECG data is obtained by adding interference data of a specific length to a specific position of the original ECG data, the electronic device can determine that the corresponding interference cancellation method is to identify the data of a specific length located at a specific position of the stored ECG data as interference data and remove the interference data from the stored ECG data, thereby realizing interference cancellation processing on the stored ECG data and obtaining the recovered ECG data.

[0107] For example, if the interference indication information indicates that the stored ECG data is obtained by reordering the bytes of the original ECG data in a specific order, the electronic device can determine that the corresponding interference cancellation method is to reorder the bytes of the stored ECG data in the original order corresponding to the specific order, thereby realizing the interference cancellation processing of the stored ECG data and obtaining the recovered ECG data.

[0108] The aforementioned ECG data processing method, in response to a recovery command for stored ECG data, reads the stored ECG data and the key segment matching the stored ECG data, and decrypts the key segment matching the stored ECG data. This determines the interference method applied to the stored ECG data, and allows for the restoration of the stored ECG data encrypted by the ECG signal acquisition box based on the corresponding interference cancellation method. This effectively achieves encryption and decryption of ECG signal data, avoiding the problem of insufficient computing power in the ECG signal acquisition box when encrypting and decrypting ECG signal data, thereby effectively improving the processing efficiency of the ECG signal acquisition box for ECG data.

[0109] In another embodiment, the interference indication information includes the length and location of the interference data. The stored ECG data is subjected to interference cancellation processing according to the interference cancellation method corresponding to the interference method to obtain the recovered ECG data. This includes: identifying the interference data in the stored ECG data according to the length and location of the interference data; and removing the interference data from the stored ECG data to obtain the recovered ECG data.

[0110] In practice, the interference indication information includes the length and location of the interference data. During the process of the electronic device performing interference cancellation processing on the stored ECG data according to the interference cancellation method corresponding to the interference method to obtain the recovered ECG data, the electronic device can identify the interference data in the stored ECG data according to the length and location of the interference data. Then, the electronic device removes the interference data from the stored ECG data to obtain the recovered ECG data.

[0111] For example, please see Figure 8 , Figure 8 An exemplary schematic diagram of ECG data decryption is provided. The electronic device decrypts the stored ECG data using a key segment that matches the data to obtain interference indication information. This interference indication information includes interference data of length X, located between byte number 3 and byte number 4. It can be seen that this interference indication information indicates that the stored ECG data was obtained by adding interference data of length X between bytes 3 and 4 of the original ECG data. The electronic device can then remove the data between bytes 3 and 4 (i.e., the interference data) from the stored ECG data to obtain the recovered ECG data, which can be used for subsequent analysis and statistical operations.

[0112] In another embodiment, the stored ECG data includes at least two bytes, and the interference indication information also includes the storage order of each byte. The stored ECG data is subjected to interference cancellation processing according to the interference cancellation method corresponding to the interference method to obtain recovered ECG data, including: adjusting the reading order of each byte in the stored ECG data according to the reading order corresponding to the storage order to obtain recovered ECG data.

[0113] The technical solution of this embodiment adjusts the reading order of each byte in the stored ECG data according to the reading order corresponding to the storage order, thereby restoring the stored ECG data encrypted by the ECG signal acquisition box. This allows the ECG signal acquisition box to effectively encrypt the acquired ECG signal data without using a complex encryption algorithm to encrypt the entire target ECG data. This avoids the problem of insufficient computing power of the ECG signal acquisition box when encrypting and decrypting ECG signal data, and also effectively improves the security of ECG data storage.

[0114] It should be understood that although the steps in the flowcharts of the embodiments described above are shown sequentially according to the arrows, these steps are not necessarily executed in the order indicated by the arrows. Unless explicitly stated herein, there is no strict order restriction on the execution of these steps, and they can be executed in other orders. Moreover, at least some steps in the flowcharts of the embodiments described above may include multiple steps or multiple stages. These steps or stages are not necessarily completed at the same time, but can be executed at different times. The execution order of these steps or stages is not necessarily sequential, but can be performed alternately or in turn with other steps or at least some of the steps or stages of other steps.

[0115] Based on the same inventive concept, this application also provides an electrocardiogram (ECG) data processing apparatus for implementing the ECG data processing method described above. The solution provided by this apparatus is similar to the implementation described in the above method; therefore, the specific limitations in one or more ECG data processing apparatus embodiments provided below can be found in the limitations of the ECG data processing method described above, and will not be repeated here.

[0116] In one embodiment, such as Figure 9 As shown, an electrocardiogram (ECG) data processing device is provided, the device comprising:

[0117] The generation module 910 is used to randomly generate interference indication information for the target ECG data in response to a storage instruction for the target ECG data;
