[0048] Next, combine Figure 1-Figure 3 The automatic generation system of an electronic calibration certificate with an anti-tampering function provided in an embodiment of the present application is introduced.

[0049] Figure 1 is a schematic diagram of the structure of the automatic generation system of the electronic calibration certificate with tamper-proof function provided in the embodiment of the present application, such as Figure 1 As shown, the system includes a calibration data module 110, a certificate generation and verification module 120, and an electronic calibration certificate generation module 130, wherein:

[0050] The calibration data module 110 is used to obtain the original data and send the original data to the certificate generation and verification module;

[0051] Optionally, the calibration data module may provide raw data to the certificate generation and verification module via a data file generated by the test system or a function interface of the test system software.

[0052] Optionally, the original data information includes calibration data, name of the testing organization, name of the testing unit, test time, testing personnel information, testing instrument, tested instrument and serial number, etc., which fully covers the valid information of the electronic calibration certificate.

[0053] The certificate generation and verification module 120 is used to receive the original data, generate a first verification code based on the original data, and send the original data and the first verification code to the electronic calibration certificate generation module;

[0054] Optionally, the certificate generation verification module can be a certificate generation verification software. The certificate generation verification module can automatically obtain the original data by adopting different strategies according to the data acquisition method of the calibration data unit. One is to automatically obtain it by searching keywords through the data file generated by the test system software. The other is to automatically obtain it through the function interface provided by the test system software.

[0055] After the certificate generation and verification module obtains the original data, it can calculate the check code through encryption algorithm and other methods, and send the data and the check code together to the electronic calibration certificate generation module to fill the original data and the check code in the generated electronic calibration certificate.

[0056] The electronic calibration certificate generating module 130 is used to receive the original data and the first verification code, and generate an electronic calibration certificate with the original data and the first verification code.

[0057] The electronic calibration certificate generation module can generate an electronic calibration certificate based on a template created by Microsoft Word. A verification code item is designed on the first page of the electronic calibration certificate, and the data information and verification code provided by the certificate generation verification software are filled in.

By comparing whether the extracted verification code and the regenerated verification code are the same, it is determined whether the data information of the electronic calibration certificate has been tampered with. If they are different, it proves that the data information has been tampered with. If they are the same, the electronic calibration certificate data is still valid.

[0073] Step 204, the certificate generation verification software confirms the key, the total number of bytes of the electronic calibration certificate and other information;

[0074] Step 205 and step 206, the certificate generation verification software uses an encryption algorithm (such as a message digest algorithm) to encrypt the information provided in step 203 and step 204 to generate a unique tamper-proof verification code;

[0075] Step 207: Add the verification code to the electronic calibration certificate to form an electronic calibration certificate with tamper-proof function.

Figure 3 As shown, in one embodiment of the present application, the following steps are performed to verify whether the electronic calibration certificate has been tampered with:

[0077] Step 301, step 302 and step 306, the certificate generation verification module extracts the verification code and data information (including the total byte length of the calibration certificate, calibration data, name of the testing organization, name of the inspection unit, test time, information of the testing personnel, testing instrument, tested instrument and serial number, etc.) by reading the electronic calibration certificate;

[0078] Steps 303 and 305 are to regenerate the verification code using an encryption algorithm (information digest) in combination with the data provided in step 302 and the key information provided by the certificate generation verification module in step 304;

[0079] Step 307, determining whether the electronic calibration certificate data information has been tampered with by comparing whether the verification code extracted in step 306 is the same as the verification code calculated in step 305;

[0080] If they are different, the data in the electronic calibration certificate has been tampered with, and step 308 is executed to add a mark indicating that the data has been modified in the electronic calibration certificate;

[0081] If they are the same, the electronic calibration certificate data has not been tampered with and step 309 is executed, and the electronic calibration certificate data is still valid.

[0083] Step 400, obtaining original data;

[0084] Optionally, the original data may be obtained through a data file generated by the test system or a function interface of the test system software.

[0085] Optionally, the original data information includes calibration data, name of the testing organization, name of the testing unit, test time, testing personnel information, testing instrument, tested instrument and serial number, etc., which fully covers the valid information of the electronic calibration certificate.

[0088] Step 420: Generate an electronic calibration certificate with the original data and the first verification code.

[0089] An electronic calibration certificate can be generated based on a template created in Microsoft Word.

[0093] Step 450, comparing the first verification code and the second verification code, if the first verification code and the second verification code are different, it is determined that the data has been tampered with.

[0094] By reading the electronic calibration certificate, extracting the verification code and data information respectively, and then regenerating the verification code based on the original data, by comparing whether the extracted verification code and the regenerated verification code are the same, it is determined whether the data information of the electronic calibration certificate has been tampered with. If they are different, it proves that the data information has been tampered with. If they are the same, the data of this electronic calibration certificate is still valid.

[0095] In some embodiments, after step 450, the method further includes:

[0096] Added an indication in the electronic calibration certificate that the data has been modified.

[0098] In some embodiments, step 410 specifically includes:

[0099] Based on the original data and the key, an encryption algorithm is used to generate a first verification code.
