Literary reader is read aloud, and audio-frequency fingerprint acquisition module gathers the user's voice, and N number of and user is obtained only by audio-frequency fingerprint algorithm
One corresponding audio-frequency fingerprint is output to encrypting module；N is >=1 positive integer.
The private key encryption password of A3, encrypting module by the use of the N number of audio-frequency fingerprint obtained as block chain wallet, respectively to this
The private key of user blocks chain wallet is encrypted, and obtains the private key ciphertext of N parts of the user's block chain wallets, and stores and deposited to private key
Store up module；Thus block chain wallet private key encryption process is completed.
Private key decrypting process is：
B1, the user picked out from block chain cryptographic libraries any one piece of the electronics Chinese reader used in step A2 into
Row is read, and audio-frequency fingerprint acquisition module gathers the user's voice, the user's audio-frequency fingerprint two is obtained by audio-frequency fingerprint algorithm, and
The audio user fingerprint two of acquisition is transferred to deciphering module.
The private key that B2, deciphering module transfer all block chain wallets of the user being stored in secret storage module is close
Text is decrypted using audio-frequency fingerprint two, if the private key ciphertext of any of which part block chain wallet is decrypted, is entered step
B3；It is all no decrypted if all of the private key ciphertext of block chain wallet, enter step B4.
B3, the transaction of block chain is initiated by transaction modules.
B4, end.
A kind of block chain wallet of the present invention is using the advantageous effect of audio encryption private key system and method：This
Invention is with block chain technology, using powerful cryptographic algorithm, electronics reader in cryptographic libraries is read aloud to adopt by user
Collect audio-frequency fingerprint, audio-frequency fingerprint is uniquely corresponding with user；And using audio-frequency fingerprint as private key encryption password；Before user is traded
It needs to provide corresponding audio-frequency fingerprint and private key ciphertext is decrypted；During decryption, pass through user's readding to identical electronics reader
Reading regains audio-frequency fingerprint and private key ciphertext is decrypted, and not only ensure that the security of private key, but also solves complicated password and hold
The problem of easily forgeing；The present invention adds one layer of protection mechanism on the basis of original private key, strengthens the security of block chain wallet, can
It is widely used in the wallet client end using block catenary system.
