Abstract

The invention provides a blockchain wallet mnemonic word generating and importing method and system, and a terminal. The method comprises the following steps: encrypting user identity information; encrypting the user fingerprint feature information; splicing and encrypting the identity encryption information and the fingerprint encryption information, and extracting the first four digits; encrypting the identity encryption information and the user fingerprint feature information as symmetric encryption keys; randomly generating a 128-bit character string, splicing the 128-bit character string with the first four-bit characters, then segmenting the 128-bit character string into 12 character string sub-segments, and enabling each character string sub-segment to correspond to one word as a memorandum word; encrypting the first three memorandum words in the 12 words by adopting a symmetric encryption key, and providing the rest nine memorandum words to the user; and linking the first three encrypted memorandum words, the user fingerprint feature information and the identity encryption information. According to the block chain wallet mnemonic word generation and import method and system and the terminal, mnemonic words are generated and imported based on the identity information and the fingerprint information of the user, and safety and reliability are achieved.

Description

technical field [0001] The present invention relates to the technical field of blockchain wallets, in particular to a method, system and terminal for generating and importing mnemonics for blockchain wallets. Background technique [0002] Blockchain is a distributed shared ledger and database, which has the characteristics of decentralization, non-tampering, full traceability, traceability, collective maintenance, openness and transparency, etc., which lays the foundation for blockchain to create trust. With the popularization of blockchain technology, more and more users have begun to have their own blockchain wallets to manage their own virtual digital assets. A blockchain wallet has only one private key and cannot be modified. Therefore, as the only certificate for owning a blockchain wallet, the security of the private key becomes crucial. [0003] In the prior art, the private key is composed of randomly generated 64-bit hexadecimal characters. Randomly generating su...
