[0035] The following will clearly and completely describe the technical solutions in the embodiments of the present invention with reference to the drawings in the embodiments of the present invention. Obviously, the described embodiments are only some embodiments of the present invention, rather than all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those of ordinary skill in the art without creative efforts belong to the scope of protection of the present invention.

[0036] The object of the present invention is to provide a method for encrypting, decrypting, and collecting original data, which can improve the authenticity of the original data.

[0037] To make the above objects, features, and advantages of the present invention more obvious and understandable, the present invention will be further described in detail below with reference to the drawings and specific embodiments.

[0038] Embodiment 1

[0039] As Figure 2 shown, the present invention provides an original data organization encryption method, and the encryption method includes:

[0040] Step S101: Obtain a data file group of a detection point; the data file group includes a detection data file and a configuration description data file; the detection data file is the detection data of the detection point; the configuration description data file includes the number of times of the accumulated collected detection data, the geographical location data corresponding to the detection point, the time information of collecting the detection data, and a check code.

[0041] Specifically, the check code is an MD5 check code.

[0042] Further, a positioning module is applied to obtain the geographical location data corresponding to the detection point.

[0043] Step S102: Apply a compression algorithm to compress the data file group to obtain an original data packet.

[0044] Specifically, the LZMA compression algorithm is applied to compress the data file group.

[0045] Step S103: Apply an encryption algorithm to encrypt the original data packet to obtain an encrypted data packet.

[0046] Specifically, the SM1 encryption algorithm is applied to encrypt the original data packet.

[0047] In practical applications, the present invention adds a configuration description file (adding geographical location information, adding time stamp information, adding check code information, adding cumulative count value information). During the data decryption process, the configuration description file is applied to check the MD5 check code to ensure the integrity of the detection data, and check and verify the geographical location information, time stamp information, and cumulative count information to ensure that the detection data is the data detected at the specified location and specified time and that the data that needs to be detected multiple times is not repeated.

[0048] Such as Figure 1 As shown, the steps of the original data organization and encryption method provided by the present invention in the actual application process are as follows:

[0049] The first step: The detection device collects the original test data of a specified detection point of the building to be measured and generates an original detection data file (assuming the data file name is ABC.dat), and enters the second step.

[0050] In the present invention, the original detection data file is the detection data file.

[0051] Step 2: The detection device obtains the geographical location coordinate information and time stamp information of the detection point through the built-in Beidou / GPS function module, creates a configuration description file with the same name (with a different extension, file name: ABC.cfg), and generates a detection data file group (the file group contains two files, namely ABC.dat and ABC.cfg; among them, ABC.dat is the detection data file; ABC.cfg is the configuration description file. Proceed to Step 3.

[0052] Among them, the specific content description of the configuration description file is as follows:

[0053] DevID = YT-DJKT-2311001; The device number is used to identify test device-related information such as the ownership, function, model, and inventory number of the test device.

[0054] ChkNm = 10201; The cumulative count value generated by the test increments by 1 for each test. Pos_X = +113.17; The longitude of the test geographical location.

[0055] Pos_Y = +23.03; The latitude of the test geographical location.

[0056] DDate = 2023-11-10; The test date, Beijing time.

[0057] DTime = 16:27; The test time, Beijing time.

[0058] FTMD5 = d7c0a9e5f081ef310d0ef51be6869fcdfbd917db; The MD5 checksum of the detection data file is used to verify the integrity of the file.

[0059] In the present invention, the configuration description file is also referred to as the configuration description data file. The detection data file group is also referred to as the data file group.

[0060] Step 3: The detection device compresses the detection data file group using the LZMA compression algorithm to generate the original data packet (ABC.pkg), and proceeds to Step 4. Among them, the original data packet (ABC.pkg) is the detection data file packet in Step 4.

[0061] Step 4: The detection device encrypts the detection data file packet using the national secret SM1 encryption algorithm to generate the encrypted data packet (ABC.spk).

[0062] Among them, the SM1 algorithm is a commercial cipher block standard symmetric algorithm. This algorithm, the SM1 block cipher algorithm, has a block length and a key length of 128 bits. The security and secrecy strength of the algorithm and the performance of related software and hardware implementations are comparable to AES. This algorithm is not publicly available and only exists in the form of an IP core in the chip.

[0063] Example 2

[0064] Based on Example 1, the present invention provides a method for decrypting original data, as Figure 3 shown, the decryption method includes:

[0065] Step S201: Obtain the geographical coordinate position of the building to be detected.

[0066] Specifically, S201 includes:

[0067] Step S2011: Determine the detection points of the building to be detected.

[0068] Step S2012: Perform GPS geographical location information positioning on the detection points, obtain the geographical coordinate positions of the detection points, and use the geographical coordinate positions of the detection points as the geographical coordinate positions of the building to be detected.

[0069] Step S202: Decrypt the encrypted data packet according to the encryption key to obtain a decrypted data packet.

[0070] Step S203: Calculate the check code of the decrypted data packet to obtain a decrypted check code.

[0071] Step S204: Compare the decrypted check code with the check code of the configuration description data file to obtain a first comparison result.

[0072] Step S205: When the first comparison result meets the first preset condition, extract the geographical location data in the configuration description data file.

[0073] Specifically, the first preset condition is that the decrypted check code is consistent with the check code of the encrypted data packet.

[0074] Step S206: Compare the geographical location data with the geographical coordinate position to obtain a second comparison result.

[0075] Step S207: When the second comparison result meets the second preset condition, extract the number of times and time information of the detected data collected cumulatively in the configuration description data file.

[0076] Specifically, the second preset condition is that the geographical location data is consistent with the geographical coordinate position.

[0077] Step S208: When the number of times and time information of the detected data collected cumulatively in the configuration description data file meet the third preset condition, obtain the detected data of the detection points.

[0078] Specifically, the third preset condition is that the number of times of the detection data accumulated in the configuration description data file is inconsistent with the number of times of the detection data accumulated at the corresponding existing detection point, and the time information is consistent with the date arranged in the work log of the detector at this detection point.

[0079] The execution steps of the original data decryption method provided by the present invention in practical applications are as follows:

[0080] The first step: Submit the data to the data center by corresponding means, such as USB flash drive transfer, serial port, network transmission, etc., and enter the second step.

[0081] The second step: The data center receives the encrypted data packet and decrypts the data packet according to the encryption key. If the decryption is successful, enter the third step, otherwise enter the sixth step.

[0082] The third step: Calculate the MD5 checksum of the detection data file and compare it with the MD5 checksum stored in the configuration description file to confirm the integrity of the data file. If they are the same, enter the fourth step, otherwise enter the sixth step.

[0083] Among them, MD5 (Message-Digest Algorithm 5), that is, the fifth version of the message digest algorithm. MD5 treats the entire file as a large text message and generates a unique MD5 message digest through an irreversible string transformation algorithm. It is used for the receiving party to recalculate the MD5 result after receiving the file to compare and know whether the file is downloaded completely or whether it has been tampered with during the transmission process.

[0084] The fourth step: Extract the geographic coordinate information in the configuration description file and compare it with the geographic coordinate position of the building to be detected. If it is correct, enter the fifth step, otherwise enter the sixth step.

[0085] Before preparing to collect detection data for the building to be tested, it is first necessary to determine the detection points of the building to be tested. After determining the detection points, perform GPS geographic location information positioning on the detection positions, and then the longitude and latitude information of the corresponding detection points can be obtained. This longitude and latitude information is used as the attached information for establishing a file for the detection project. After receiving the encrypted detection data packet, decrypting and decompressing it to restore it to a detection data file group, extract the geographic coordinate information from the configuration description file, and compare it with the attached longitude and latitude information of the project, then it can be known whether the detection data is the effective detection data collected at the specified longitude and latitude position.

[0086] The fifth step: Extract the test cumulative value in the configuration description file, which should have no duplication with the test cumulative value of the existing test data. At the same time, extract the date and time stamp information in the configuration description file and compare it with the date and time stamp arranged in the work log. If it is correct, complete this round of testing, otherwise enter the sixth step.

[0087] In order to prevent testers from repeatedly submitting an existing test data as new test data, or submitting a single test data as multiple test data, the date attached to the configuration file is used to avoid repeated submission of old data, and the test cumulative number is used to prevent one data from being used to impersonate multiple test data. The test cumulative value is automatically maintained by the test equipment. Each time the equipment is started for a test, the cumulative value is automatically increased by 1.

[0088] After each test data submission, the attached configuration description file information is also saved to the server together with the test data for permanent storage. When new test data is submitted, the server searches the database to determine that there should be no duplicate test cumulative values.

[0089] Step 6: If the test data is unqualified, please conduct a second test.

[0092] Step S301: using a detection device to obtain a data file group of a detection point, and processing the data file group to obtain an encrypted data packet, and transmitting the encrypted data packet to a data processing center.

[0093] Step S302: The data processing center obtains the geographic coordinate position of the detected building, and obtains the detection data of the detection point according to the geographic coordinate position of the detected building and the encrypted data packet.

[0094] As a specific implementation method, the detection device transmits the encrypted data packet to the data processing center in the following ways: USB disk transfer, serial port transmission and network transmission.

[0095] In addition, the collection of raw data is fully closed-loop managed and automatically uploaded to the data center via the network after collection, reducing the number of human intermediate links. However, the requirements for hardware resources and working environment are relatively high.

[0100] Fourth: By encrypting the original monitoring data, it is possible to prevent artificial data tampering and ensure the authenticity of the original sampling data;

[0101] Fifth: By attaching geographical coordinate information and data collection time stamps to the original detection data, it is ensured that the data is collected at a specified location and at a specified time.
