Abstract

A decentralized information transmission system comprising: an information generating end, first and second blockchain networks, and an information receiving end, an information data transmitted by the generating end is encrypted by a public key into an encrypted file, a hash value is generated by a hash value generating module, the first blockchain network receives the hash value and the encrypted file, the second blockchain network receives the hash value and a receiving end address, the receiving end generates a data reading request for the second blockchain network, the second blockchain network transmits the hash value to the receiving end, the receiving end generates a data demanding request for the first blockchain network, the first blockchain network transmits the encrypted file to the receiving end, and the receiving end decrypts the encrypted file with a private key to obtain the information data transmitted by the generating end.

Claims13

Dependent claims

A decentralized information transmission system comprising:

an information generating end, the information generating end having a hash value generating module and a receiving end public key, an information data to be transmitted by the information generating end being encrypted by the receiving end public key into an encrypted file, and the information generating end generating a hash value corresponding to the encrypted file by the hash value generating module;
a first blockchain network, the first blockchain network being signally connected to the information generating end, and the encrypted file hash value and the encrypted file generated by the information generating end being transmitted to the first blockchain network and stored by the first blockchain network;
a second blockchain network, the second blockchain network being signally connected to the information generating end, the information generating end generating a receiving end address by the receiving end public key, and the encrypted file hash value and the corresponding receiving end address generated by the information generating end being transmitted to the second blockchain network;
and
an information receiving end, the information receiving end being signally connected to the first blockchain network and the second blockchain network, the information receiving end generating a data reading request for the second blockchain network with the receiving end address, the second blockchain network transmitting the encrypted file hash value of the receiving end address to the information receiving end according to the data reading request, the information receiving end generating a data demanding request for the first blockchain network according to the encrypted file hash value, the first blockchain network transmitting the encrypted file of the encrypted file hash value to the information receiving end according to the data demanding request, and the information receiving end decrypting the encrypted file with a receiving end private key to obtain the information data to be transmitted by the information generating end.
