Technical Field

[0001] The present invention relates to the field of electronic digital data processing technology, and in particular to a method and system for secure storage of agency data based on blockchain technology. Background Art

[0002] With the continuous increase in data volume and the development of storage systems towards networking and distribution, data security storage has become increasingly important. Traditional storage systems face the risk of data leakage, tampering and destruction. The data security storage background of blockchain technology was born in the context of the global financial crisis. It was proposed to solve the problems of lack of trust and excessive intermediaries in the traditional financial system. Blockchain technology, with its unique characteristics of decentralization, immutability and transparency, provides new solutions for data security storage and has been widely used in finance, supply chain, medical and other fields. Blockchain technology eliminates the need for centralized intermediaries, allowing data to be distributed and verified among multiple nodes, thereby improving the reliability and security of data. Blockchain uses cryptography technology and consensus mechanism to ensure that data cannot be tampered with or deleted once written to the blockchain. This feature makes blockchain an ideal choice for data security storage.

[0003] The existing data storage method based on blockchain technology stores data in the form of a database. The database can protect data through backup and recovery. At the same time, the database supports concurrent access, allowing multiple users to read and write data at the same time.

[0004] For example, the invention patent announcement with announcement number: CN112732695B discloses a method for secure deduplication of cloud storage data based on blockchain, including: sending the generated file tag to the cloud storage service provider for duplication detection; if the result is that the file is duplicated, the user will generate a file duplication storage log, and execute the smart contract through the smart contract management center to integrate the storage log into a transaction and upload it to the blockchain for storage, so as to safely save the current storage status information; if the result is that the file is not duplicated, the key server generates the user's authority key by constructing a role-level hash tree, uses the authority key to perform secure encryption operations on the data, and uploads the ciphertext to the cloud storage server for storage; with the assistance of the smart contract management center, a file non-duplicate storage log and transaction are generated.

[0005] For example, the invention patent with announcement number CN113536358B announces a method for secure storage of private data based on blockchain, including: constructing several storage nodes, generating several copies for each data row, the number of copies matches the storage node, and the copies are associated with numbers; generating an obfuscated value for each field of the data row, and the obfuscated value falls within the range of the true value of the field; randomly distributing the true value of the data row field to several copies for storage, and filling the obfuscated value with the field that is not assigned to the true value; assigning several copies to several storage nodes for storage; the fields of the data row and the allowed length of the fields constitute a data structure; the storage block has an area for storing numbers; when retrieving private data from the storage node, use the private key to sign the number and send it to the storage node, and after verification by the storage node, provide a copy corresponding to the number.

[0006] However, in the process of implementing the technical solution of the invention in the embodiments of the present application, the present application found that the above technology has at least the following technical problems:

[0007] In the existing technology, since all transactions and information on the blockchain are open and transparent, any node can view and verify them, making all transaction records public.

[0032] The embodiments of the present application solve the problem of low confidentiality in the storage of agency data in the prior art by providing a method and system for secure storage of agency data based on blockchain technology. The stored agency data is obtained through preset data information, and then the stored agency data is encrypted to obtain an encryption efficiency index, and the encrypted agency data is obtained in combination with a preset encryption range.

Finally, access conditions are set in the blockchain network according to the request condition-related index obtained from the first encrypted agency data. If the request condition-related index exceeds the preset access range, a prohibited access prompt is sent to the preset personnel to ensure the access security of the first encrypted agency data, thereby improving the confidentiality of the agency data.

[0033] The technical solution in the embodiment of the present application is to solve the problem of low confidentiality when storing the above-mentioned agency data. The overall idea is as follows:

[0034] By encrypting the stored agency data to obtain the encryption efficiency index and combining it with the preset encryption range to obtain the encrypted agency data, then obtaining the transmission stability index based on the encrypted agency data and combining it with the preset transmission range to obtain the first encrypted agency data, and finally setting access conditions in the blockchain network based on the request condition-related index obtained from the first encrypted agency data, the effect of improving the confidentiality of agency data storage is achieved.

[0035] In order to better understand the above technical solution, the above technical solution will be described in detail below in conjunction with the accompanying drawings and specific implementation methods.

[0036] like Figure 1 As shown, it is a flow chart of the method for secure storage of agency data based on blockchain technology provided by an embodiment of the present application. The method is applied to a method system for secure storage of agency data based on blockchain technology. The method includes the following steps: acquiring storage agency data according to preset data information, the storage agency data including sensitive information and storage quality information; encrypting the storage agency data to obtain an encryption efficiency index, and acquiring encrypted agency data in combination with a preset encryption range, the encryption efficiency index is used to evaluate the quality of encryption processing of the storage agency data, the encryption processing is to encrypt the storage agency data using a quantum key to ensure the confidentiality of the storage agency data, and the encrypted agency data represents the encrypted storage agency data; transmitting the encrypted agency data to the blockchain network for storage and obtaining a transmission stability index, and acquiring the first encrypted agency data in combination with the preset transmission range, the transmission stability index is used to evaluate the accuracy of transmission during the transmission of the encrypted agency data, the first encrypted agency data represents the data in the encrypted agency data that meets the preset conditions corresponding to the preset transmission range, and the blockchain network is used to improve the security of data storage; acquiring a request condition related index according to the first encrypted agency data, and setting access conditions in the blockchain network in combination with the request condition related index, the access conditions are used to prevent abnormal access to the first encrypted agency data, and the request condition related index is used to describe the insecurity of the preset personnel access process.

[0037] In this embodiment, the transmission stability index can be calculated in combination with the first width of the digital pulse. This is a key indicator for evaluating the quality of data transmission. A high transmission stability index indicates that the number of pulses during data transmission is stable and within the expected range. Otherwise, it may indicate that there are problems or instability in data transmission. The higher the encryption efficiency index, the better the quality of encryption processing for stored agency data. The smaller the request condition-related index, the higher the security level during access by preset personnel. This achieves improved confidentiality when storing agency data.

[0038] Furthermore, the specific acquisition process of stored agency data is as follows: classify the preset data information to obtain sensitive information, the classification is based on the purpose and nature of the stored agency data, sensitive information represents data that has been classified by purpose and nature, and the preset data information represents information that the agency needs to store; filter the stored agency data according to preset screening conditions to obtain storage quality information, the preset screening conditions are based on conditions set in the historical agency data storage process, and the screening is used to obtain significant parameters in the historical agency data storage process, the storage quality information represents significant parameters in the historical agency data storage process, and the significant parameters include digital pulse width, valid discrete value, and response time communication times in the agency data storage process.

[0039] In this embodiment, preset data information generally refers to various data that an agency or system has predetermined to be stored and processed, generally involving the agency's transactions, business activities, orders, etc.; the data is stored according to its purpose and nature to obtain sensitive information so that the agency can understand and manage the data. Significant parameters can help the agency understand the performance of the storage system and how it processes data. When processing stored agency data, data protection and privacy regulations must be strictly observed to ensure that the security and confidentiality of the data are not violated. The use of automated data processing can improve the efficiency and accuracy of data acquisition and storage quality information; the confidentiality of agency data is improved.

[0040] Furthermore, the specific process of obtaining the encryption efficiency index is as follows: quantum keys are distributed between the sender and the receiver according to the storage agency data, and the quantum keys are used to convert the storage agency data into ciphertext; the number of communications is measured by a counter and a synchronous clock at a first preset time point, and the first preset time point represents the time point set in the process of distributing the quantum key, and the number of communications represents the number of communications of the relay entangled quantum pairs that can be controlled within 1 second; the number of communication paths is measured by a counter at the first preset time point, and the number of communication paths represents the number of communication paths of the relay entangled quantum pairs; the quantum entanglement dimension is measured by a quantum state analyzer at the first preset time point, and the encryption efficiency index is obtained in combination with the number of communications and the number of communication paths.

[0041] In this embodiment, the quantum key uses the principles of quantum mechanics, such as the no-cloning theorem and measurement non-interference, to ensure that the key can only be known by the legitimate communicating parties. This non-cloning property ensures that the key cannot be eavesdropped or cracked. The key distributed through the quantum channel will not leak information even if it is intercepted during the transmission process. This is because the intercepted quantum state will be destroyed, and the communicating parties will be aware of the potential eavesdropping behavior, thereby discarding the current key and trying to redistribute it. The counter can determine the transmission frequency and stability of the quantum signal within a certain period of time, thereby evaluating the performance of the system and possible attack risks. During the quantum key distribution process, the synchronous clock is used to ensure the time synchronization of the sender and the receiver. Time synchronization is the key to ensuring quantum state measurement and quantum key distribution, so as to ensure the timing correctness of the measurement and the real-time nature of the communication; it achieves the improvement of confidentiality when storing agency data.

[0042] Furthermore, the encryption efficiency index is calculated using the following formula:

[0043]

[0044] In the formula, α represents the encryption efficiency index, T m represents the number of communications at the mth first preset time point, m=1, 2, ... n, m represents the number of the first preset time point, n represents the total number of the first preset time points, W m Indicates the number of communication paths at the mth first preset time point, N m represents the quantum entanglement dimension at the mth first preset time point, ΔQ represents the preset channel capacity threshold, and e represents a natural constant.

[0045] In this embodiment, the preset channel capacity threshold is a value set based on the relevant data stored in the database of the relevant agency data. The number of communications T m The range is 0-100 (times), the number of communication channels is W m The range is 5-30 (paths), and the quantum entanglement dimension N m The range is 1-10, and the preset channel capacity threshold is 100 (bps). Without considering multiple times, assuming n = 1, the change table of the encryption efficiency index is shown in Table 1:

[0046] Table 1 Changes in encryption efficiency index

[0047]

[0048] As can be seen from Table 1, as the number of communications T m The number of communication paths W m The gradual increase of and the quantum entanglement dimension N mAs the encryption efficiency index α gradually increases, the encryption efficiency index α also gradually increases. The larger the encryption efficiency index α is, the better the quality of encryption processing for storage agency data is; the confidentiality of agency data storage is improved.

[0049] Furthermore, the specific process of obtaining the encrypted agency data is as follows: the encryption efficiency index is compared with the preset encryption range. If the encryption efficiency index is within the preset encryption range, it is judged that the storage agency data meets the preset encryption conditions, and the corresponding storage agency data is recorded as the encrypted agency data; otherwise, it is judged that the storage agency data does not meet the preset encryption conditions.

[0050] In this embodiment, statistics and analysis are performed on the data in the process of storing agency data in a historical period to obtain a preset encryption range. For example, a linear regression model between the encryption efficiency index and the parameters can be established based on historical data, and the Pearson correlation coefficient can be used to evaluate the linear relationship between variables. The linear regression model can be trained using the collected historical data, and the established model can be used to make predictions or inferences. The estimated value of the preset encryption range is obtained by taking the average value of the prediction results of the model; statistics and analysis are performed on the agency data stored in the historical period, and the average value is taken based on the analysis results to determine the characteristics, magnitude, sensitivity, etc. of the data. These data may include confidential documents, personal information, financial data, etc., to ensure the security of agency data during storage and transmission, prevent data from being accessed or tampered with by unauthorized parties, and ensure that data stored in the agency is properly encrypted and protected to protect sensitive information, reduce security risks, and comply with regulatory requirements; and improve the confidentiality of agency data when it is stored.

[0051] Furthermore, the specific acquisition process of the first encrypted agency data is as follows: at a second preset time point, a first width of a digital pulse is measured by a pulse width meter, the second preset time point represents a time point set during the encrypted agency data transmission process, and the first width represents the width of a digital pulse during the encrypted agency data transmission process; at the second preset time point, a first discrete value of the digital pulse is measured by a digital pulse counter, the first discrete value represents the number of valid discrete values ​​of the digital pulse during the encrypted agency data transmission process, and a transmission stability index is obtained in combination with the first width of the digital pulse; the transmission stability index is compared with a preset transmission range, if the transmission stability index is within the preset transmission range, it is judged that the encrypted agency data meets the pre-transmission conditions and is recorded as the first encrypted agency data, otherwise it is judged that the initial encrypted agency data does not meet the preset transmission conditions.

[0052] In this embodiment, statistics and analysis are performed on data in the process of storing agency data within a historical period to obtain a preset transmission range. For example, a linear regression model between a transmission stability index and parameters can be established based on historical data, and the Pearson correlation coefficient can be used to evaluate the linear relationship between variables. The collected historical data is used to train the linear regression model, and the established model is used to make predictions or inferences. An estimated value of the preset transmission range is obtained by taking the average value of the prediction results of the model. A valid discrete value usually refers to a discrete value that is defined as valid or meaningful in data transmission. A pulse width meter is mainly used to measure the time width of a pulse signal, that is, the length of time that a pulse lasts on the time axis. A digital pulse counter is used to accurately count the number of pulses in a digital signal. The pulse width meter and the digital pulse counter provide reliable data support for determining whether encrypted agency data meets preset transmission conditions by measuring and counting the width and number of digital pulses. By measuring the pulse width and discrete values, the rate, stability and quality of data transmission can be evaluated, thereby improving the confidentiality of agency data storage.

[0053] Furthermore, the transmission stability index is calculated using the following formula:

[0054]

[0055] In the formula, β represents the transmission stability index, T i represents the first width of the i-th second preset time point, i=1,2,...r, i represents the number of the second preset time point, r represents the total number of the second preset time points, N i represents the first discrete value of the i-th second preset time point, T0 represents the preset width threshold, N0 represents the preset discrete threshold, ΔR represents the preset transmission threshold, and e represents a natural constant.

[0056] In this embodiment, the preset width threshold is a value set based on the relevant data stored in the relevant agency data in the database, the preset discrete threshold is a value set based on the relevant data stored in the relevant agency data in the database, and the preset transmission threshold is a value set based on the relevant data stored in the relevant agency data in the database; Figure 2 As shown, it is a statistical diagram of the transmission stability index provided in the embodiment of the present application, where it is assumed that the total number of preset time points r=100, the first width T i The range is 0-50 (ns), the first discrete value N i The range is 1-500, and N i Take the integer power of 2, the preset width threshold T0 is 25 (ns), the preset modulation level threshold N0 is 32, and the preset transmission threshold is 100 (bps). It can be seen from the figure that as the first width T i The gradual decrease and the first discrete value N iThe transmission change index gradually increases. The larger the transmission change index is, the higher the accuracy of the transmission during the encrypted agency data transmission process is, and the confidentiality of agency data storage is improved.

[0057] Furthermore, the specific setting process of the access conditions is as follows: at a third preset time point, a response time of the preset personnel's access is measured by a timer, the third preset time point represents the time period set during the preset personnel's access to the first encryption agency data, and the response time represents the average processing time of each access request; at the third preset time point, a total access time is measured by a timer, the total access time represents the total time of the preset personnel's access, at the third preset time point, a counter is used to measure the number of accesses, and a request condition related index is obtained in combination with the response time and the total access time; the request condition related index is compared with the preset access range, and if the request condition related index exceeds the preset access range, a prohibited access prompt is sent to the preset personnel to ensure the security of the first encryption agency data, otherwise an access acceptance prompt is sent to the preset personnel.

[0058] In this embodiment, the data in the process of storing the agency data in the historical period is statistically analyzed to obtain the preset access range. For example, a linear regression model between the request condition related index and the parameter can be established based on the historical data, and the Pearson correlation coefficient can be used to evaluate the linear relationship between the variables. The linear regression model can be trained using the collected historical data, and the established model can be used to predict or infer. The estimated value of the preset access range is obtained by taking the average value of the prediction results of the model. The timer is used to measure the time interval or the passage of time. It usually uses a certain clock signal as a reference and can accurately measure the time difference between the occurrence of one event and the occurrence of another event. The counter is used to count the number of occurrences of a specific event or signal. It can count electronic pulses, trigger signals, input pulses, etc., and is used to record the number of occurrences of events in real time. The timer is used to measure the average processing time of each preset personnel access request. It starts and stops the timing to track the time taken for each request from the beginning to the end. These response time measurements are crucial to evaluating the system response efficiency and help ensure that the system can respond to access requests in a timely manner within the preset time period; the confidentiality of the agency data is improved.

[0059] Furthermore, the request condition relevance index is calculated using the following formula:

[0060]

[0061] In the formula, γ h represents the request condition related index of the hth third preset time period, h=1, 2, ..., f, h represents the number of the third preset time period, f represents the total number of the third preset time periods, N hrepresents the number of visits in the hth third preset time period, L h represents the response time of the hth third preset time period, T h represents the total access duration of the hth third preset time period, L0 represents the preset response threshold, T0 represents the preset duration threshold, N0 represents the preset number threshold, Δμ represents the preset throughput threshold, and e represents a natural constant.

[0062] In this embodiment, the expression of the number of visits in the hth third preset time period is: Among them, N h ′ is the number of visits in the hth third preset time period, N h 0 is the reference access number data of the hth third preset time period, ΔN h is the reference deviation of the number of visits, Among them, L h ′ is the response time data of the hth third preset time period, L h 0 is the reference response time data of the hth third preset time period, ΔL h is the response time reference deviation, Among them, T h ′ is the total access duration data of the hth third preset time period, T h 0 Reference access total duration data of the hth third preset time period, ΔT h The reference deviation for the total duration of the visit.

[0063] It should be understood that the preset response threshold is a value set based on the relevant data of the relevant agency data storage in the database, the preset number threshold is a value set based on the relevant data of the relevant agency data storage in the database, the preset duration threshold is a value set based on the relevant data of the relevant agency data storage in the database, the preset throughput threshold is a value set based on the relevant data of the relevant agency data storage in the database, the access number data of the hth third preset time period is obtained by measurement, the response time data of the hth third preset time period is obtained by measurement, the total access duration data of the hth third preset time period is obtained by measurement, and the reference access number data is obtained by taking the average value after statistical analysis of the access number data of the hth third preset time period. It indicates that the reference response time data is expressed by taking the average value after statistical analysis on the response time data of the hth third preset time period, and the reference total access time data is expressed by taking the average value after statistical analysis on the total access time data of the hth third preset time period; the response time reference deviation is obtained by calculating the response time data and the response time reference data through the deviation formula, the access number reference deviation is obtained by calculating the access number data and the access number reference data through the deviation formula, and the total access time reference deviation is obtained by calculating the total access time data and the total access time reference data through the deviation formula, wherein the deviation formula is the difference between the reference data and the corresponding measured value; the confidentiality of the agency data is improved when it is stored.
