Detailed Description
As shown in fig. 1, in view of this, in an embodiment of the present invention, a data transmission method for a detection device includes the following steps:
s1, each detection device encrypts the accuracy rate parameter of the detection device, stores the accuracy rate parameter in the local area, and sends the accuracy rate parameter to the server after encryption; the method comprises the steps of classifying detection equipment in a server according to accuracy parameters of the detection equipment, and dividing the detection equipment into first node equipment and second node equipment, wherein the first node equipment and the second node equipment are the detection equipment participating in data transmission verification.
Each detection device obtains its own accuracy parameter in advance, which may be a specific value, such as 95.66% or 85.23%. The classification of the detection devices in the server according to the accuracy parameters of the detection devices may be performed as follows: the detection equipment with high detection accuracy usually bears higher detection task amount, and the detection equipment with low detection accuracy usually uses low frequency as alternative equipment. Of course, the detection accuracy cannot be too low, for example, a second preset threshold may be set, and the detection device below the second preset threshold will not be used, for example, 85% is defined as the second preset threshold. The accuracy parameter of the detection device can be used not only as a parameter for distinguishing the detection device, but also for encrypting in subsequent steps, because an illegal user cannot simultaneously obtain all encrypted accuracy parameters.
The first node device and the second node device are accessed to the internet and used as detection devices participating in data transmission verification, and each detection device can be used as a relay node in the data transmission process of the detection result.
S2, configuring initial change factors and factor change rules under the first node device and the server; an initial change factor is configured in the second node device.
Optionally, different changing factors may correspond to different algorithms, so that the difficulty in cracking the algorithms is increased, and therefore, the algorithm types can be determined in both the detection device and the server by changing the factors. The initial changing factor may be a random value such as 45 or 200 or other values, and the factor change rule may be a fixed value added each time or a fixed value multiplied.
And S3, after the detection equipment detects the substance to be detected, mixing the detection results according to the initial change factors, inserting the mixed results into a path list containing adjacent values, and then respectively sending the path list to all adjacent detection equipment.
The adjacent values include the unique identifier of the sending detection device, the forwarding times (for example, the value is 1 when the sending is first obfuscated, the value is 2 when the sending is second obfuscated, and the forwarding is also 2), and the type of the receiving device (the first detection device, the second detection device, and the server). And when the receiving equipment is of the server type, the detection result is sent after the receiving equipment is confused or forwarded.
Alternatively,
the step S3 includes:
s31, detecting the detected result after the detection of the substance to be detected is finished by the detecting equipment, and randomly generating a plurality of confusion parameters, wherein the sum of 1 of the confusion parameters is less than or equal to the number of the adjacent detecting equipment;
s32, inserting random numbers into the confusion parameters and encrypting according to the accuracy parameters of the detection equipment; inserting an initial change factor into the detection result and encrypting according to the self accuracy rate parameter of the detection equipment;
and S33, respectively inserting a path list containing adjacent values into the encrypted confusion parameter and the encrypted detection result, packaging to obtain a confused result, and sending the confused result to the adjacent detection equipment.
S4, the adjacent detection device receiving the obfuscated result is a first node device, and the step S5 is skipped to; the adjacent detection device which receives the obfuscated result is the second node device, and the process goes to step S6;
s5, when the adjacent detection device receiving the confusion result is the first node device, updating the adjacent value in the path list, updating the initial change factor according to the factor change rule to obtain the updated change factor, re-confusing the received confusion result according to the updated change factor to obtain a re-confusing result, sending the re-confusing result to other adjacent detection devices, and jumping to the step S7.
The neighboring device is a neighboring device that does not send data to the first node device that received the obfuscated result. For example, the detection devices adjacent to the detection device a include a detection device B, a detection device C, and a detection device D. In step S3, the detection device a sends the obfuscated results to each of the detection device B, the detection device C, and the detection device D. The detection device B is a first node device, and the detection device B sends a re-confusion result to the detection device E, the detection device F, and the detection device G adjacent to the detection device B, but does not send the re-confusion result to the detection device a, the detection device C, and the detection device D, so that the detection device E, the detection device F, and the detection device G are called other detection devices.
The same applies to the case where the neighboring detection device B is the second node device.
Alternatively,
the step S5 includes:
s51, when the adjacent detection device receiving the obfuscated result is a first node device, updating the initial change factor according to the factor change rule to obtain an updated change factor;
s52, the first node equipment randomly generates a plurality of confusion parameters, and the sum of 1 of the confusion parameters is less than or equal to the number of other adjacent detection equipment;
s53, inserting a random number into the confusion parameter and encrypting according to the accuracy parameter of the first node equipment; inserting the updated change factors into the obfuscated result and encrypting according to the accuracy parameters of the first node equipment;
s54, inserting the path list containing the updated adjacent value into the encrypted confusion parameter and the encrypted detection result, respectively, and then encapsulating the path list to obtain a re-confusion result, and sending the re-confusion result to the adjacent detection device, and then proceeding to step S7.
Inserting the path list containing the updated neighbor values includes: and updating the unique identification code, the forwarding times and the type of the receiving equipment of the sending detection equipment.
S6, when the adjacent detection device receiving the confusion result is the second node device, resolving an adjacent value from the confusion result, updating the adjacent value, writing the updated adjacent value into the path list, forwarding the received confusion result to other adjacent detection devices, and jumping to the step S7;
and S7, judging whether the detection result is sent completely according to the path list, when the detection result is sent completely, restoring the confused result in the server through the path list, the initial change factor and the factor change rule to obtain the detection result, and when the detection result is not sent completely, jumping to the step S4.
Alternatively,
the step S7 includes:
s71, resolving adjacent values from the path list of the re-obfuscated result or the obfuscated result;
s72, judging whether the sending of the detection result is finished according to the adjacent value, and jumping to the step S73 when the sending is finished; when the transmission is not completed, jumping to step S4;
s73, the server judges the detection equipment participating in the transmission process through the adjacent values in the path list, and decrypts the extracted encrypted self-accuracy parameters from the server to obtain the self-accuracy parameters corresponding to the participating detection equipment;
s74, the server determines the corresponding change factor when the participating detection equipment is encrypted through the adjacent value, the initial change factor and the factor change rule in the path list;
and S75, the server decrypts the re-obfuscated result or the obfuscated result according to the corresponding change factor when the participating detection equipment is encrypted and the self accuracy parameter corresponding to the participating detection equipment, and screens out the detection result from the decrypted result.
Under the condition that different changing factors can correspond to different algorithms, the server can also sequentially decrypt the re-obfuscated result or the obfuscated result layer by layer through different algorithms.
In the data transmission method of the inspection equipment according to the present invention,
in step S1, before each detection device encrypts its accuracy parameter and sends it to the server, the method further includes:
the accuracy of the detection equipment is checked in advance, and the accuracy parameters can be encrypted and then sent to the server after the check is passed.

6. The data transmission method of a test device according to claim 5,
the pre-checking of the accuracy of the detection device, after the check is passed, the self accuracy parameter can be encrypted and then sent to the server, and the method comprises the following steps:
the detection equipment detects the predetermined components and sends the obtained first detection data to the server for standardized analysis to generate a parameter comparison model;
the biochemical substance to be detected is sent to the detection equipment for detection, and the obtained second detection data is sent to the server; the server judges whether the fluctuation of the second detection data is greater than the expected loss value or not through the parameter comparison model, and when the fluctuation of the second detection data is less than or equal to the expected loss value, the second detection data of the biochemical substance to be detected is determined to be in accordance with the expectation; and detecting the biochemical substances to be detected repeatedly for many times to obtain the accuracy of the detection equipment.
