To key, the public key of user information and user is stored in block chain network by system, and private key is stored in local by user, by with
Family oneself keeping；The safety for having ensured information transmission is stolen without worrying, protects privacy of user.
Preferably, further comprising the steps of:
If receiving the information sent to user terminal, jumps into block chain network, obtain public affairs corresponding to the user
Key.
Preferably, further comprising the steps of:
After obtaining public key, transmitted information is encrypted, and be sent to user terminal.
Preferably, further comprising the steps of:
After user terminal receives encryption information, the private key for being stored in local user side is transferred, which is solved
It is close, obtain raw information.
In the above-mentioned technical solutions, it if necessary to send information to user, arrives first and gets user couple in block chain network
The public key answered is sent to user by network after the information sent will be needed to encrypt by public affairs, uploads in network this when
Defeated data are encrypted data, and user is decrypted after receiving data with the private key of oneself, even if the data of network transmission are stolen
It is also ciphertext data after taking, can not be also decrypted without corresponding private key, this completes safe transmissions, have reached secure chat
Purpose.
The present invention also provides a kind of, and the secure user data based on block chain sends system, and its technical solution is as follows:
A kind of secure user data based on block chain sends system, including key production module, public key storage module and
Private key storage module, in which:
Key production module generates a pair of secret keys based on the registration information for receiving user's registration information；
Public key storage module, for registering customers as information and corresponding public key is uploaded to block chain network and stores；
Private key storage module, for corresponding private key to be stored in local user side.
It preferably, further include public key acquisition module, for jumping into area when receiving the information sent to user terminal
Block chain network obtains public key corresponding to the user.
Preferably, further include information encrypting module, after obtaining public key, transmitted information is encrypted, concurrently
It send to user terminal.
It preferably, further include private key deciphering module, for transferring and being stored in local after user terminal receives encryption information
The encryption information is decrypted in the private key of user terminal, obtains raw information.
The beneficial effects of the present invention are:
