[0060] The invention will be further described in detail below with reference to the accompanying drawings and examples.
[0061] The privacy protection of the present invention limits the user access data authority by writing intelligent contracts, to ensure privacy data; the data-oriented privacy protection is dynamically constructed by using an improved AES algorithm, making its various properties of random transformation. Increase the security of the encryption algorithm; simultaneously use the summary algorithm, calculate the resulting ciphertext calculation to ensure the integrity of the data. Using an improved AES algorithm and summary algorithm In ensuring data encryption security and integrity in a charity system, enhances operational efficiency, so that the entire system has sufficient credibility, effectively compensating the risk of traditional charitable system data leakage.
[0062] Such as Figure 5 As shown, the system based on block chain chain chain chain chain, p...
