[0002] Public welfare donations play an extremely important role in social development, and the flow of funds and the implementation of projects involved are highly concerned by the public. However, there are many defects in the traditional public welfare donation data storage methods.

[0003] On the one hand, the centralized database storage is vulnerable to internal and external attacks, and the security and integrity of data are difficult to guarantee. Once the data is leaked or tampered with, it will not only damage the trust of donors, but also may lead to the chaos and stagnation of public welfare projects; on the other hand, the traditional storage method lacks transparency, and donors are difficult to track the specific use and whereabouts of donated funds in real time. The information asymmetry is likely to trigger public doubts about public welfare undertakings. Moreover, it is difficult to effectively integrate and share data between different public welfare organizations, which is not conducive to the comprehensive supervision and overall management of regulatory departments, and hinders the standardized and large-scale development of public welfare undertakings. Based on the above reasons, the present invention proposes a public welfare donation blockchain encrypted data storage device and a data encryption storage method. Summary of the Invention

This transparency helps to enhance the public's trust and support for public welfare undertakings and promote the healthy and sustainable development of public welfare undertakings. A further detailed description is made of a public welfare donation blockchain encrypted data storage device and a data encryption storage method of the present invention.

[0038] Reference Figure 1-2 , the present invention: A public welfare donation blockchain encrypted data storage device, comprising:

[0039] A multi-channel collection module, which realizes docking with various public welfare donation platforms, payment channels, and offline donation record systems, and widely collects various relevant data generated during the public welfare donation process;

[0040] Specifically, the public welfare donation-related data includes donor information, donation item information, donation platform, and beneficiary information;

[0041] The donor information includes the donor's name, ID number, and contact information. When the donor makes an anonymous donation, the donor information is replaced by the receiving donation platform;

[0042] The donation item information includes the donation amount, donation items, quantity of donations, and donation time;

[0043] The donation platforms include existing public and private donation platforms, online and offline donation platforms, and personal re-donations;

[0044] The beneficiary information includes beneficiary personnel, beneficiary projects, and beneficiary organizations.

[0045] Furthermore, a standardized data collection protocol is adopted to ensure compatibility with different data formats from various sources, enabling seamless data docking and rapid data collection. Meanwhile, it has the function of preliminary data screening and cleaning to remove duplicate, incorrect, or incomplete data, improving the quality and usability of the data.

[0046] The hybrid encryption processing module is used to perform matching processing on the collected public welfare donation data and conduct hybrid encryption operations using multiple encryption algorithms based on the relevant public welfare donation data information after the matching processing.

[0047] Specifically, the hybrid encryption processing module uses an asymmetric encryption algorithm to encrypt sensitive data such as the donor's key identity information and donation amount to generate a high-strength digital signature, thereby ensuring the authenticity and non-repudiation of the data source. Subsequently, for the main part of the large-scale donation data, a symmetric encryption algorithm is used for rapid encryption to improve the overall encryption efficiency. Moreover, the hybrid encryption processing module realizes the generation, storage, and management of encryption keys, and regularly updates the keys to enhance the security of encryption.

[0048] Furthermore, the parameters of the encryption algorithm can be dynamically adjusted according to the importance level and security requirements of the data to achieve a flexible and precise encryption strategy. At the same time, the key storage adopts a combination of a hardware encryption module and distributed storage. The hardware encryption module ensures the secure storage of the key locally, while the distributed storage disperses some information of the key to multiple nodes in the blockchain network, reducing the risk of key loss or theft.

[0049] The blockchain storage module constructs a multi-level blockchain architecture and stores the encrypted public welfare donation data into the constructed public welfare donation blockchain network.

[0050] Specifically, the blockchain storage module includes a basic public welfare donation data storage unit, a donation project indexing unit, and a supervision and auditing unit.

[0051] The basic public welfare donation data storage unit adopts a sharding storage technology to shard massive donation data according to multiple dimensions such as donation project categories, geographical scopes, and time periods, and then stores them in different blockchain shard networks, significantly improving the data storage and query efficiency.

[0052] The donation project indexing unit constructs an intelligent indexing mechanism based on a distributed hash table, which can quickly locate the blockchain shard position where the relevant donation project data is located according to the donor's query requirements, the supervision agency's auditing requirements, etc.

[0053] The supervision and auditing unit sets up an independent supervision channel and data verification nodes specifically for the supervision agency, and uses supervision smart contracts to realize the functions of real-time monitoring, compliance inspection, and abnormal data warning of public welfare donation data.

[0054] Further, the blockchain structure constructed by the blockchain storage module includes multiple orderly arranged blocks. Each block consists of a block header and a block body. The block header records the hash value of the data, which is obtained by performing a hash operation on the encrypted data and is used to uniquely identify the data content of the block, the hash value of the previous block, which is used to achieve the chain connection between blocks and ensure the order and integrity of the data, the timestamp, which is used to accurately record the time point of data storage, and information related to the consensus algorithm. The block body stores the encrypted public welfare donation data.

[0055] Furthermore, the multi-level architecture design realizes the separation and collaborative optimization of data storage, index query, and supervision and audit functions. The sharding storage technology effectively solves the scalability problem of blockchain data storage and improves the storage and processing capabilities of large-scale public welfare donation data. The intelligent index mechanism based on the distributed hash table greatly improves the speed and accuracy of data query and meets the diverse query needs of different users. The independent design of the supervision and audit layer and the application of supervision smart contracts strengthen the overall supervision ability of regulatory agencies over public welfare donation data and ensure the compliance operation of public welfare projects and the security of funds.

[0056] The donation data query module creates a highly intelligent interactive data query platform. Donors can query the details of donation data at any time and place through various convenient methods and receive real-time push notifications on the progress of donation projects.

[0057] Specifically, the query methods for donors and beneficiaries to access data in the donation data query module include mobile applications, social media mini-programs, and voice query assistants. The realization of data query by donors and beneficiaries is based on one or more of the donation order number, ID card information, donation platform information, beneficiary information, or donation item information.

[0058] The verification and feedback module is used to track various materials for public welfare donations in real time and feedback to the system to achieve real-time supervision of the materials. Both donors and beneficiaries can directly communicate and provide feedback to ensure the accurate matching of donated materials with beneficiaries.

[0059] Specifically, the accurate matching of donated materials with beneficiaries by the verification and feedback module can be verified based on the active feedback of beneficiaries, real-time supervision of the data of donated items, and communication between donors and beneficiaries.

[0060] A data encryption storage method for a data encryption storage device of a public welfare donation blockchain includes the following steps:

[0061] S1: Connect the multi-channel collection module to various public welfare donation platforms, payment channels, and offline donation record systems. Once new donation data is generated, immediately initiate the collection process;

[0062] S2: Collect all relevant data including donor information, donation amount, donation time, donation project information, and fund flow information, etc., in accordance with the pre-set data collection standards and formats, to ensure the integrity and comprehensiveness of the data;

[0063] S3: Use the hybrid encryption processing module to encrypt the processed donation information data. Use the ECC elliptic curve encryption algorithm to encrypt sensitive data such as the donor's key identity information and donation amount to generate a digital signature. For the remaining main body part of the donation data after asymmetric encryption processing, use the AES advanced encryption standard algorithm for encryption;

[0064] S4: Calculate the hash value of the encrypted data, then combine information such as the hash value, the hash value of the previous block, the timestamp, and the encrypted data into a block body, and then calculate other relevant information in the block header according to the selected consensus algorithm to complete the construction of the block;

[0065] S5: Broadcast the constructed block to each node in the public welfare donation blockchain network. After receiving the block, the node first verifies the legality of the block, including verifying whether the hash value in the block header is correct, whether the hash value of the previous block matches, whether the timestamp is reasonable, and whether the consensus algorithm-related information meets the requirements.
