[0036] In the following description, many specific details are set forth in order to provide a thorough understanding of the present invention. However, the present invention can be implemented in many other ways different from those described herein, and those skilled in the art can make similar extensions without departing from the connotation of the present invention. Therefore, the present invention is not limited by the specific implementations disclosed below.

[0037] The present invention provides a traceability system based on anti-tampering of grain inspection data, as Figure 1 shown, including: a sample coding module, an original data coding module, a report generation module, and a report verification module; ensuring that the inspector does not know the source of the sample, preventing "favoritism in grain inspection", generating an encrypted detection report code, ensuring that the detection results can be verified, and identifying data tampering behaviors. The system includes:

[0038] The sample coding module generates an original sample code for the grain sample to be detected; after the grain sample is mixed and sub-sampled, a sub-sample code of the grain sample is generated based on the sub-sample number of the original sample code.

[0039] The original data coding module generates an original data code of the grain sample based on the sub-sample code of the grain sample and the original data of the grain sample detection items; the original data is subjected to hash calculation to generate an original data hash value.

[0040] The report generation module is used to generate a grain detection report according to the original data of the grain sample detection items; an inspection report code of the grain sample is generated based on the original data code, the grain detection report type code, and the original data hash value.

[0041] The report verification module is used to generate a grain detection report hash value by performing hash calculation on the data content of the grain detection report; if the original data hash value is consistent with the grain detection report hash value, it is confirmed that the grain inspection data has not been tampered with.

[0042] 1. Sample coding module

[0043] The sample is taken manually or automatically, generates a business number from the grain informatization system or is manually recorded, generates an original sample code in this system, and generates a sub-sample code after mixing and sub-sampling. The inspector gets the sub-sampled sample and cannot know the sample source by scanning the code or entering the sub-sample code, thus avoiding "favoritism in grain inspection" to the greatest extent.

[0044] The original sample code is specifically:

[0045] Business number + variety code + serial number + timestamp.

[0046] Wherein:

[0047] Business number: The business number generated by the grain informatization system;

[0048] Variety code: See Appendix 1, "Variety Dictionary Table".

[0049] Serial number: Three digits, starting from 001.

[0050] Timestamp: Millisecond-level timestamp.

[0051] Based on the sub-sampling number of the original sample code, the sub-sampling code of the grain sample is generated as:

[0052] Hash value of the original sample code + sub-sampling number + weight + timestamp + QR code.

[0053] Wherein:

[0054] Hash value of the original sample code: Calculate the 32-bit hash value (MD5) of the original sample code.

[0055] Sub-sampling number: Two digits, starting from 01.

[0056] Weight: Usually 500, 100, 50, representing 500g, 100g, and 50g samples commonly used in grain inspection respectively.

[0057] Timestamp: Millisecond-level timestamp.

[0058] QR code: QR two-dimensional code.

[0063] Sub-sampling code + test item code + serial number + timestamp

[0064] Wherein:

[0065] Sub-sampling code: "Sub-sampling code" mentioned above.

[0071] 3. Report generation module

[0072] Each inspection report generated by the system has a unique code.

[0073] Inspection report code:

[0074] Original data code + Report type code + Serial number + Original data hash value + Timestamp.

[0075] Among them:

[0076] Original sample code: the "original data code" mentioned above;

[0078] Serial number: three-digit number, starting from 001;

[0079] Original data hash value: all the original data included in this test report form an array, and a 32-bit hash value (MD5) is calculated;

[0080] Timestamp: millisecond-level timestamp.

[0083] 4. Report verification module

[0084] A visual report verification interface that supports calculating the hash value of a grain inspection report by calculating the 32-bit hash value of the data content of the grain inspection report; comparing the original data hash value in the inspection report code with the grain inspection report hash value. If they are the same, it is determined that the grain inspection data has not been tampered with and the data is true and valid; if they are different, it is determined that the grain inspection data has been tampered with.

[0085] Based on the same inventive concept, the present invention also provides a traceability method for preventing tampering of grain inspection data, the process of which is as Figure 2 shown, including:

[0086] Step S201: Generate an original sample code for the grain sample to be detected; after mixing and sub-sampling the grain sample, generate a sub-sample code for the grain sample based on the sub-sample number of the original sample code;

[0087] Step S202: Generate the original data code of the grain sample based on the sub-sample code of the grain sample and the original data of the grain sample detection items; calculate the hash value of the original data to generate the original data hash value;

[0088] Step S203: Generate a grain inspection report based on the original data of the grain sample inspection items; generate an inspection report code for the grain sample based on the original data code, the grain inspection report type code, and the original data hash value.

[0089] Step S204: Generate a grain inspection report hash value by performing a hash calculation on the data content of the grain inspection report; if the original data hash value is the same as the grain inspection report hash value, it is confirmed that the grain inspection data has not been tampered with.

[0090] Further, the original sample code is specifically:

[0091] Business number + variety code + serial number + timestamp.

[0092] Further, after the grain sample is mixed and sub-sampled, generate a sub-sample code for the grain sample based on the sub-sample number of the original sample code, including:

[0093] Obtain the sub-sample number of the original sample code by scanning the code or entering it.

[0094] Generate the sub-sample code for the grain sample based on the sub-sample number of the original sample code as: original sample code hash value + sub-sample number + weight + timestamp + QR code.

[0095] Further, generate the inspection report code for the grain sample based on the original data code, the grain inspection report type code, and the original data hash value, specifically:

[0096] Inspection report code: original data code + report type code + serial number + original data hash value + timestamp.
