Description

TECHNICAL FIELD

[0002] Insurance companies, pharmaceutical companies and medical device manufacturers can conduct accurate marketing according to the medical data of patients, but for medical institutions, the leakage of medical data of patients can easily lead to the opposition of the doctor-patient relationship and bring negative effects to the medical institutions. In order to avoid the leakage of medical data of patients, it is increasingly important to maintain information security by keeping the storage, access and transmission of data confidential.

[0003] Medical institutions usually have multiple branches, such as some third-grade class-A hospitals usually have multiple hospital areas. When the same patient has corresponding medical data stored in different hospital areas, the doctors in the current hospital area need to call the medical data stored in other hospital areas, but the security and reliability of the remote access link between different hospital areas cannot be guaranteed.

[0004] In the related art, a data private line is usually built between branches to build a closed private internal network between branches in a medical institution, so as to ensure the security and reliability of data access and transmission. Although the data private line can ensure data security, the data private line has high use cost. In addition, the medical institution only uses the data private line during working hours, and needs to pay corresponding fees during non-working hours, resulting in low utilization rate. In addition, the data volume of medical data is large, and the transmission capacity of the data private line is very limited compared with the data volume to be transmitted. SUMMARY

It should be understood that the data used in this way can be interchanged under appropriate circumstances, so that the application examples can be implemented in an order other than that illustrated or described herein, and the objects distinguished by "first", "second", etc. are usually a category and do not limit the number of objects, for example, the first object can be one or more.

In the description of the present application, "a plurality of" means two or more, and "several" means one or more.

[0033] In the medical field, the medical data of a patient includes electronic medical records, medical images, etc. The patient can receive treatment in different branches of the same medical institution, and the medical data of the patient needs to be transmitted between the branches to facilitate the diagnosis and treatment of medical staff, so the medical data transmission method provided by the present application can be used. In addition, a data access system is provided in the medical institution, which includes a plurality of data access devices, of course, the data access devices are provided in each branch. Each data access device includes a camera and a Beidou chip. The camera is used to collect a face image, and the Beidou chip is used to communicate data with a Beidou satellite navigation and positioning system, that is, the data access device can collect a face image through the camera and communicate data with the Beidou satellite navigation and positioning system through the Beidou chip.

[0034] Figure 1 The steps of the medical data transmission method provided by an embodiment of the present application are shown in the figure. The medical data transmission method of the present application includes the following steps:

[0035] Step S110, acquiring a face image collected by a camera.

[0036] Step S120, receiving time information and position information sent by a Beidou satellite navigation system based on a Beidou chip.

[0037] The time information includes time corresponding to a time zone where the data access device is located, and the location information includes longitude and latitude parameters corresponding to a location where the data access device is located. It can be understood that the Beidou chip is a chip set including an RF (Radio Frequency) chip, a baseband chip and a microprocessor, and the data access device can receive corresponding signals through the Beidou satellite to realize positioning and navigation and satellite timing functions.

[0038] In step S130, a key parameter is generated according to the time information and the location information.

[0039] The key parameter is used for encrypting the obtained face image, and the data access device can generate the key parameter according to the time information and the location information.

[0040] In an embodiment, for the generation of the key parameter, the present application also provides a step flow as shown in Figure 2 The step flow provided by the present application for generating the key parameter is shown in the figure, and the specific steps are as follows: Figure 2 The step flow provided by the present application for generating the key parameter is shown in the figure, and the specific steps are as follows:

[0041] In step S210, a target interval is selected from two preset intervals according to the time information.

[0042] In step S220, a target distance corresponding to a first side of a target triangle is determined according to the longitude and latitude parameters carried by the location information and the target interval.

[0043] In step S230, a light intensity value corresponding to the target distance is determined based on a preset mapping relationship between distance and light intensity, and the light intensity value is taken as the key parameter.

[0044] It can be understood that the preset interval is associated with the time information, and the data access device can select a corresponding preset interval according to the obtained time information. The time of a day is divided into a first time period and a second time period. For example, the first preset interval is associated with the first time period, and the second preset interval is associated with the second time period. Therefore, the target interval can be selected according to the time period in which the time information falls.

[0045] For example, for the location of the data access device, the natural light received is different at different times, such as the angle of incidence and the intensity of the light. During the day, the sun is shining, and at night, the moon reflects the sunlight. Correspondingly, the first preset interval can be the sun-earth distance, and the second preset interval can be the moon-earth distance.

[0046] After the target interval is determined, a target triangle can also be constructed, wherein the target triangle is a triangle with the target interval as the base length, the arc length corresponding to the arc angle between the longitude and latitude parameters and the direct point, and the distance corresponding to the radius of the earth as the second side length.

[0047] The direct point is associated with the target distance, that is, after the target distance is determined, the corresponding direct point can also be determined. In the target triangle, the target distance is the length of the base, the target distance is the length of one side (that is, the first side), and the distance corresponding to the radius of the earth is the length of the other side (the second side). In the case where the longitude and latitude parameters of the location of the data access device are determined, the radian angle corresponding to the arc length between the longitude and latitude parameters and the direct point can also be determined.

[0048] And the data access device stores a preset mapping relationship between distance and illumination intensity, and the mapping relationship is as follows:

[0049]

[0050] Wherein, B is the illumination intensity value; L is the luminosity value, which is a fixed value; d is the target distance.

[0051] Correspondingly, the illumination intensity value can be used as a corresponding key parameter to encrypt the face image by the data access device. It should be noted that in the present application, the illumination intensity value is an analog value, which is used to assist encryption.

[0052] Therefore, the natural law that the natural light received by the location of the data access device is different at different times can be used to determine a target distance, and then based on the preset mapping relationship, the corresponding analog value is calculated, so that the randomness of the key is improved, and the security of data transmission is effectively improved.

[0053] It should be noted that for the generation of the key parameter, the time parameter and the location parameter can also be converted into digital character format and converted into binary to obtain data with corresponding byte number by connecting the connectors, and then the data is equally divided into two sub-data, and the operation result of the two sub-data after the AND operation is used as the key parameter.

[0054] Step S140, encrypt the face image based on the key parameter to generate an encrypted target image.

[0055] After the key parameter is determined, the data access device can encrypt the face image based on the key parameter, and use the encrypted image as the target image. Figure 3 The step flowchart for encrypting the face image provided by an embodiment of the present application includes the following steps in some embodiments:

[0056] Step S310, input the face image into the StyleGAN model based on the StyleGAN model.

[0057] Step S320, introduce the key parameter as a noise parameter into the StyleGAN model, and generate a noise weight.

[0058] Step S320, generate a target image by superimposing the noise weight on the face image.

[0059] It can be understood that the StyleGAN model is a face generation model, which can further introduce noise to randomly control the generation result and enhance the richness of the generated picture. Therefore, after inputting the face image into the StyleGAN model, the key parameter is also introduced into the StyleGAN model as a noise parameter to calculate the corresponding noise weight. For example, the input of the model is given by the forward function, so that the noise is introduced into the model, and then the noise weight is superimposed on the face image, so that the model outputs a target image.

[0060] Therefore, the present scheme adopts the StyleGAN model and the corresponding key parameter to encrypt the face image, generates a target image by encrypting the face image, so that the receiving end decrypts the target image to restore the target image and performs verification, improves the security of access verification, and makes remote access more secure and reliable.

[0061] Step S150, select a target device from other data access devices, and send a data packet to the target device for the target device to perform data access verification according to the data packet.

[0062] When selecting the target device, the selected other data access device is determined, for example, when the user needs to remotely access the data access device II through the data access device I, the data access device II is the target device.

[0063] After determining the target device, the current data access device sends a data packet to the target device, wherein the data packet includes a target image, time information and location information, so that the target device performs data access verification according to the data packet to determine whether remote access can be performed.

[0064] Step S160, establish a data transmission channel with the target device under the condition of passing the data access verification.

[0065] After determining that the target image carried in the received data packet can meet the demand, the target device can send feedback information to the sender of the data packet to make the sender determine that the current data access verification has been passed, so that the sender establishes a data transmission channel with the target device.

[0066] From the above scheme, the data access device can generate a corresponding key by using the time information and the position information obtained through the Beidou satellite, and encrypt the face image according to the key, so as to determine that the user logs in the data access device in the data access system and requests to obtain the medical data, thereby effectively constructing a secure data transmission channel with other data access devices, reducing the risk of loss of medical data, and further ensuring the reliability of remote data access.

[0067] In some embodiments, the data access device is correspondingly provided with a face library in which face images corresponding to each user are stored. For example, in a branch of a medical institution, when a patient visits the branch, the face image of the patient is correspondingly recorded and stored in the data access device corresponding to the branch. In addition, for medical staff of the medical institution, the face images corresponding to each medical staff are stored in the data access device corresponding to each branch.

[0068] For the data access device of a branch, it can receive the data packet sent by the data access device corresponding to another branch. Therefore, when receiving the data packet, i.e., when the data access device is the target device, the target image in the data packet needs to be verified.

[0069] Figure 4 The step flow chart for access verification provided by an embodiment of the present application is as follows:

[0070] Step S410, determining a key parameter for decryption according to the time information and the position information carried by the data packet.

[0071] Step S420, decrypting the target image based on the key parameter to generate a restored image.

[0072] Step S430, searching and comparing the restored image in the face library to determine whether to establish a data transmission channel with the data access device sending the data packet.

[0073] It can be understood that for the data access device, it can be a sender of the data packet or a receiver of the data packet. Therefore, after receiving the data packet, the device parses the data packet to obtain the time information and the position information, and then can regenerate the key parameter based on the scheme for generating the key parameter provided in the above embodiments to perform decryption.

[0074] After the key parameter is determined, the target image can be decrypted based on the key parameter, and then the restored image is obtained. For example, in an embodiment, based on the StyleGAN model, the noise weight corresponding to the time information and the position information is determined, and then the target image is input into the StyleGAN model, and the negative value of the determined noise weight is introduced, so as to remove the noise weight of the target image and extract the restored image.

[0075] The face library corresponding to the device records the face images of the users, and the recorded users are all users who can access data, so that the restored image is searched and compared in the face library, such as compared with each image, to select the face image of the same user as the restored image.

[0076] Whether the device establishes a data transmission channel with the sender of the data packet is determined based on the search and comparison result. For example, according to the search and comparison result, it is determined that there is a face image of the same user as the restored image, and a data transmission channel is established, and if there is no face image of the same user as the restored image, a data transmission channel is not established with the sender.

[0077] Therefore, when serving as a target device, the data access device parses the received data packet and determines the corresponding key parameter therefrom to decrypt the target image, and searches the image in the face library to determine whether to establish a data transmission channel, which can reduce the risk of loss of medical data and further ensure the reliability of remote data access.

[0078] In an embodiment, for the users whose face images are stored in the face library, the users include first-class users and second-class users, and the data access permission of the first-class users is higher than that of the second-class users. Therefore, when searching and comparing the restored image, it is also judged whether the user is a first-class user or a second-class user.

[0079] When the restored image is a face image corresponding to a first-class user, the device establishes a data transmission channel with the data access device sending the data packet based on the 5G network slicing method; when the restored image is a face image corresponding to a second-class user, a data sub-zone is generated through one-way gate isolation, and a data transmission channel is established with the data access device sending the data packet based on the 5G network slicing method.

[0080] Among them, the data sub-zone is used to store the accessible data for the second-class user to access. That is, the device independently sets a data sub-zone for the second-class user through one-way gate isolation, to push data to the data sub-zone, so that the data access of the second-class user is limited.

[0081] For example, the first type of user corresponds to medical staff, and the second type of user corresponds to a patient. When performing remote access, if the first type of user performs access, all medical data of the patients can be pushed to the first type of user; if the second type of user performs access, part of medical data corresponding to the second type of user, such as a diagnosis result and medical images, can be pushed to the second type of user. Therefore, different levels of data access permissions are divided for different users, and medical data is pushed according to corresponding permissions, which helps to reduce the risk of data leakage.

[0082] In some embodiments, the data access device is also in communication connection with a management server, and the data access device also sends location information to the management server at intervals. After receiving the location information, the management server also compares the location information received before and after. When the location information changes, the management server sends location change information to the data access device.

[0083] When the data access device receives the location change information, the data access device deletes the face image in the face library, so that the verification cannot be completed, and the medical data cannot be accessed, further reducing the occurrence of data loss.

[0084] For example, a medical institution includes a first branch and a second branch, wherein the first branch is provided with a first data access device, and the second branch is provided with a second data access device. After patient A first visits the first branch, the medical data a of patient A is stored in the first branch. Therefore, when patient A visits the second branch, the face image can be collected through the second data access device, and the second data access device performs the medical data transmission method provided in the above embodiments to interact with the first data access device, such as sending corresponding data packets.

[0085] When the first data access device obtains the restored image and finds the face image corresponding to the restored image in the corresponding face library, the patient A is allowed to access the corresponding medical data. In addition, the medical staff of the second branch can also collect face images through the second data access device, and access the medical data a of patient A after verification.
