Example

[0045] A method for securely transmitting data of an abdominal and pelvic muscle function recovery system, comprising:

[0046] On the data upload side, perform the following operations:

[0047] Obtaining abdominal and pelvic muscle function recovery system data. Abdominal and pelvic muscle recovery system data refers to data generated by users when using the abdominal and pelvic muscle function recovery system to perform abdominal muscle and pelvic floor muscle training and recovery, including users' physiological data, training data, and feedback data, such as the strength and coordination of pelvic floor muscles, the frequency of use and training intensity of users when using the abdominal and pelvic muscle function recovery system, and users' satisfaction with the training when using the abdominal and pelvic muscle function recovery system. Abdominal and pelvic muscle function recovery system data can monitor the process of users using the abdominal and pelvic muscle function recovery system, upload the abdominal and pelvic muscle function recovery system data to the data analysis end, and evaluate the use effect of the abdominal and pelvic muscle function recovery system, and then adjust the training plan of the abdominal and pelvic muscle function recovery system. Therefore, it is necessary to upload the abdominal and pelvic muscle function recovery system data, and because the abdominal and pelvic muscle function recovery system is the user's private data, the uploading of the abdominal and pelvic muscle function recovery system data also needs to meet the requirements of secure transmission;

[0048] The abdominal and pelvic muscle function recovery system data is divided into several blocks and recorded as abdominal and pelvic muscle function recovery system data block F i , i=1, 2, 3, ..., I, I is the total number of abdominal and pelvic muscle function recovery system data slices, which is determined by the amount of abdominal and pelvic muscle function recovery system data. For each abdominal and pelvic muscle function recovery system data slice F i Execute the graph data conversion operation, which refers to converting the abdominal pelvic muscle function recovery system data piece F originally stored as continuous binary characters i Convert to graph data storage format to avoid abdominal pelvic muscle function recovery system data corresponding to the abdominal pelvic muscle function recovery system data slice F i Direct exposure to the transmission network to build an abdominal and pelvic muscle function recovery system data map T i , Actual data location map W i and the position mask map Y i , Abdominal and pelvic muscle function recovery system data chart T i Part of the location in the abdominal and pelvic muscle function recovery system data sheet F is stored i The corresponding actual data, that is, the abdominal and pelvic muscle function recovery system data chart T i Each coordinate point in the image will store information, but the information stored at each coordinate point is not necessarily the actual data, but also includes added noise data. This operation can greatly increase the difficulty for untrusted users to obtain data from the abdominal and pelvic muscle function recovery system; Actual data location diagram W i Used to store abdominal and pelvic muscle function recovery system data sheet F i The corresponding actual data is in the abdominal and pelvic muscle function recovery system data chart T i The position information and sequence information in the data sheet F of the abdominal and pelvic muscle function recovery systemi The corresponding actual data arrangement order can be used to restore the complete abdominal and pelvic muscle function recovery system data sheet F based on the sequence information i ; Position mask map Y i Used to store the actual data location map W i The location of the trusted data in the W, where the trusted data refers to the actual data location map W i In order to further avoid data leakage, the actual data location map W i The position information and sequence information in the data are not all correct, and noise data is also added; the hash function is used to restore the system data piece F for each abdominal and pelvic muscle function. i Perform hash value calculation to construct abdominal and pelvic muscle function recovery system data map T i The corresponding first tag hash value R i , and then pass the first mark hash value R i The actual data location map W i and the position mask map Y i Marking is performed so as to realize the hash value R according to the first mark i Find the corresponding actual data location map W i and the position mask map Y i , and then execute the abdominal and pelvic muscle function recovery system data sheet F i recovery;

[0049] Get the transmission public key E from the data target end i , and based on all the transmission public keys E i For all abdominal and pelvic muscle function recovery system data chart T i Perform nested encryption operation to construct the encrypted data of the abdominal and pelvic muscle function recovery system. The nested encryption operation refers to converting the encrypted abdominal and pelvic muscle function recovery system data into i Unencrypted abdominal and pelvic muscle function recovery system data diagram T i+1 After the combination, encryption is performed, which can further increase the difficulty of brute force cracking of the pelvic muscle function recovery system data during transmission; in the process of each encryption operation, the hash value of the data to be encrypted is calculated by the hash function to construct the second tag hash value P i and pass the second tag hash value P i The transmission public key E used i Mark; transmit public key E i It is generated by the key generator at the data target end, generally using the RSA algorithm, and each transmission public key E i There is a corresponding decryption private key U i ;

[0050] Randomly select I actual data location graphs W from the decoding information base i , I position mask images Y i and a transmission public key E i The decoding information set is composed, and the I actual data location map W corresponding to the decoding information set is i , I position mask images Y i and a transmission public key E i The decoding information set is deleted from the decoding information library, and then the decoding information set and the abdominal and pelvic muscle function recovery system encryption data are encrypted and transmitted to the data target end. The encryption operation here is generally performed through the key pair set in advance by the data target end; the decoding information library consists of several actual data location diagrams corresponding to the abdominal and pelvic muscle function recovery system data. i , position mask map Y i and transmit the public key E i The decoding information base is initially empty.

[0051] The actual data location map W corresponding to the abdominal and pelvic muscle function recovery system data i , I position mask images Y i and a transmission public key E i Stored in the decoding information library; it should be noted that, at the data upload end, the abdominal-pelvic muscle function recovery system data will be continuously uploaded. Therefore, the actual data location map, location mask map and transmission public key corresponding to different abdominal-pelvic muscle function recovery system data will be stored in the decoding information library, and in the decoding information set and the abdominal-pelvic muscle function recovery system encrypted data transmitted at the same time, the decoding information set does not include the actual data location map, location mask map and transmission public key required for the abdominal-pelvic muscle function recovery system encrypted data, but includes the actual data location map, location mask map and transmission public key required for the previously transmitted abdominal-pelvic muscle function recovery system encrypted data. With this split transmission method, even if other users brute-force crack the key pair corresponding to the decoding information set and the abdominal-pelvic muscle function recovery system encrypted data, it is difficult to obtain the abdominal-pelvic muscle function recovery system data in the absence of the decryption order and graph structure conversion method corresponding to the transmission key, which increases the difficulty of brute-force cracking of the abdominal-pelvic muscle function recovery system data during transmission;

[0052] On the data target side, perform the following operations:

[0053] The decoding information set and the encrypted data of the abdominal-pelvic muscle function recovery system are obtained through the decryption operation. The decryption operation here refers to the operation performed through the key pair set in advance by the data target end; and the decoding information set is stored in the target decoding library. Since the actual data location map, location mask map and transmission public key in the decoding information set are randomly selected, it is necessary to use the target decoding library to find the actual data location map, location mask map and transmission public key required for any abdominal-pelvic muscle function recovery system encrypted data;

For each selected abdominal and pelvic muscle function recovery system data vector, assign the abdominal and pelvic muscle function recovery system data vector to any coordinate point in the first feature map. The length and width of the first feature map are determined by the developer. The number of channels is N. The arrangement sequence number and the assigned coordinate point position A of the selected abdominal and pelvic muscle function recovery system data vector in the candidate set are recorded. The abdominal and pelvic muscle function recovery system data piece F can be reorganized through the arrangement sequence number. i , assign a sequence number to the coordinate point corresponding to the coordinate point position A in the second feature map, and assign a value of 1 to the coordinate point corresponding to the coordinate point position A in the third feature map, which is used to indicate that the data corresponding to the coordinate point position A in the second feature map is valid; until all the abdominal and pelvic muscle function recovery system data vectors in the to-be-selected set are selected, the first feature map, the second feature map, and the third feature map are output;

[0059] For the first feature map, the unassigned coordinate points are assigned to the noise vector. The length of the noise vector is N and is set in advance by the developer. Until all the coordinate points in the first feature map are assigned, the first feature map is recorded as the pelvic muscle function recovery system data map T i ; For the second feature map, assign the unassigned coordinate points to random integers to avoid exposure of the arrangement sequence number until all the coordinate points in the second feature map are assigned, and the second feature map is recorded as the actual data position map W i ; For the third feature map, assign the unassigned coordinate points to 0, representing the actual data position map W i Invalid data in the third feature map is removed until all coordinate points in the third feature map are assigned values, and the third feature map is recorded as the position mask map Y i .

[0063] Step S3: Determine whether "k<I" is established. If "k<I" is not established, it means that the abdominal and pelvic muscle function recovery system data graph T i All have been selected, and the process goes to step S5; if "k<I" is established, it means that the abdominal and pelvic muscle function recovery system data graph T i If all have not been selected, proceed to step S4;

[0064] Step S4: Assign k+1 to k, and encode the abdominal and pelvic muscle function recovery system data graph G k-1 Abdominal and pelvic muscle function recovery system data chart T k After the combination, encryption operation is performed to construct the encrypted data graph G of the abdominal and pelvic muscle function recovery system k , return to step S3;
