Public welfare money monitoring and tracking method for preventing data leakage based on block chains

Abstract

The invention discloses a public welfare money monitoring and tracking method for preventing data leakage based on block chains, and the method comprises the steps that S1, a supervisor receives donation information which comprises a donator and a welfare money amount remitted by the donator to a bank; S2, the supervisor opens an account for the donator on the blockchain and generates a pair of homomorphic encryption keys, and the supervisor records an encrypted token of a good money amount remitted by a bank in the donation direction on the blockchain; S3, according to the service fee proportion of the bank, calculating the service fee of the amount ciphertext in a homomorphic manner through a hybrid multiplication method, calculating the actual donation sum after the service fee is deducted through an addition homomorphic manner, and recording the actual donation sum on a chain; S4, the supervisor records a circulation object and a circulation amount at each circulation node according to the offline good money circulation dynamic state; and S5, after donation completion information of the good money is received, the supervisor compares the sum of the circulation amount at each node with the actual donation sum consistently and records the sum on a chain.

Description

technical field [0001] The invention relates to the field of donation monitoring, in particular to a method for monitoring and tracking public welfare donations based on blockchain to prevent data leakage. Background technique [0002] Donation platforms in traditional public welfare industries such as the Red Cross have some problems, such as: [0003] First, there is the problem of fraud on the donor side.

Problems solved by technology

[0006] Although there is a technology in the existing technology that uses the blockchain to supervise public welfare donations and the circulation of charitable funds, the risk of data leakage caused by completely transparent and open display of donations has never been prevented, and there is a lack of prevention in the existing technology Charity flow monitoring mechanism for data leakage
