Description

Technical Field

[0001] The present invention relates to the technical field of digital currency management, and in particular to a system and method for realizing the exchange of financial subsidies for deposits based on digital currency. Background Art

[0004] Financial subsidies come in many forms, including price subsidies, employee living subsidies, interest subsidies, etc.

[0005] Price subsidies are mainly used to support the production of agricultural and sideline products in order to stabilize market prices.

[0006] Employee living allowance is intended to ensure the basic living needs of employees.

[0007] Interest subsidies are intended to reduce the financing costs of enterprises.

[0008] The recipients of financial subsidies can be state-owned enterprises, collective enterprises, commercial sectors, colleges and universities, scientific research institutions and other enterprises and institutions, as well as urban residents, individual business operators, etc.

[0009] The issuance of financial subsidies currently relies on on-site work methods in which financial personnel manage and then the masses receive them. This method is not only inefficient, but the error rate is also affected by human subjectivity, which reduces satisfaction.

[0010] To this end, the present invention proposes a system and method for realizing the exchange of fiscal subsidies for deposits based on digital currency. Summary of the invention

[0011] In view of the defects in the prior art, the present invention provides a system for realizing the exchange of fiscal subsidies for deposits based on digital currency, comprising:

[0020] S4: The financial management end receives the process request information and verifies the supporting materials and documents attached to the process;

[0021] S5: After successful verification, the financial management end sends a transfer request to the cloud server;

[0022] S6: The cloud server establishes a connection with the bank. According to the amount, transfer time and transfer account of the transfer request, the bank transfers the account funds of the financial management end to the account provided by the public end.

[0023] S7: After receiving the transfer information, the public can transfer or withdraw money through the bank.

[0024] Preferably: in the step S4, the process confirmation includes the following steps:

[0025] S41: Divide the process into multiple process nodes according to the level, and each level of the process includes multiple process nodes of different types;

[0026] S42: Each process node corresponds to one or more financial management staff;

[0027] S43: The process chain transfer starts from the last node. When entering each node, the process is pushed to each type of node in the node according to the audit type contained in the process.

[0028] S44: After each node has been reviewed and found to be correct, the process files are summarized and passed upward, and then this step is repeated until each node has been reviewed and the process is confirmed.

[0029] Preferably: in the step S4, if an erroneous step occurs during the review of any node, the process will be fed back to the public end for modification. After the modification, the process chain will be reviewed again from the last node.

[0030] Preferably: in the steps S1-S7, the cloud server communicates with the financial management end, the public end, and the bank end using a multi-threaded staggered encryption communication method.

[0031] Preferably: the multi-threaded staggered encryption communication method comprises the following steps:

[0032] A1: Establish multiple communication threads between the cloud server and the financial management end, the public end, and the bank end;

[0033] A2: Split the communication data into sub-blocks less than or equal to the number of threads;

[0034] A3: Encrypt the sub-blocks and then randomly assign each sub-block to a communication thread;

[0035] A4: The data of each sub-block is transmitted through the corresponding communication thread, and during transmission, the communication time starting point and communication frequency of each thread are different;

[0036] A5: After receiving the data, the receiver decrypts the data.

[0037] Preferably: in step A2, data segmentation includes the following steps:

[0038] A21: Determine the number N of sub-blocks to be divided;

[0039] A22: Get the total number of characters M of the communication data;

[0040] A23: Divide the communication data into M / N data units, each data unit contains N data characters;

[0041] A24: Extract the data corresponding to the number of bits in each data unit, and then combine them into data transmission sub-blocks, and number each data transmission sub-block according to the number of bits stored in it.

[0042] Preferably: in step A3, the encryption comprises the following steps:

[0043] A31: Establish a mapping function set f i a And the encryption function set f i b ;

[0045] A33: According to the integer part of the obtained result, select the encryption function corresponding to the number in the encryption function;

[0046] A34: The result of the mapping function transformation is then transformed twice using an encryption function to obtain a ciphertext.

[0047] Preferably: in step A31, the mapping function is:

[0048] where x min is the minimum value in the data, xmax is the maximum value in the data;

[0049] Where e is the base of natural logarithms;

[0050] where x min is the minimum value in the data, x max is the maximum value in the data;

[0051] f a (x) = x p , where p<1;

[0052] in

[0053] Any combination of a (x) is the encrypted data, and x is the data before encryption.

[0054] Preferably: the cryptographic function set f i b Can be used with the mapping function set f i a Same or different.

[0055] The beneficial effects of the present invention are embodied in:

[0056] 1. The present invention uses process chain as the transmission form and data currency as the basis to achieve the interconnection between the public end, the financial management end and the bank end, so that the entire financial subsidy request, submission, review and issuance are managed in a systematic way, which increases efficiency and reduces the error rate.

[0057] 2. The present invention is based on a cloud server and adopts a multi-threaded staggered encryption communication method. On the one hand, multiple threads communicate, which increases the difficulty of interception and cracking. At the same time, even if interception and cracking occur, the communication time sequences of multiple threads are different, and the data cannot be reliably combined, thereby increasing data security.

[0058] 3. The present invention divides data into blocks and adopts a method of reorganizing the number of bits after equidistant division, thereby further increasing the complexity of data encryption and ensuring data security. BRIEF DESCRIPTION OF THE DRAWINGS
