AI Technical Summary
Technical Problem
The existing mnemonic phrase consists of 12 English words, which is not easy to remember and is prone to errors, leading to failure in private key recovery. Furthermore, blockchain transactions lack error correction functions and privacy protection.
Method used
It uses Chinese mnemonic phrases and error correction encoding to generate multi-level key trees A and B, uses Chinese mnemonic phrases to recover the root key, and adds error correction function when generating public keys, supporting address error correction and anonymity protection during transactions.
Benefits of technology
It reduces the difficulty of remembering keys, increases the success rate of private key recovery, reduces transaction errors, and ensures the privacy protection of the recipient.

Abstract
This invention relates to a method, apparatus, and medium for storing error-correcting digital assets using mnemonic phrases. The method includes: a user registering a digital asset account and entering a custom password; the user terminal generating a random root key and expanding the root key into key trees A and B, and encrypting key trees A and B respectively; generating a Chinese mnemonic phrase based on the random root key; the user terminal using the leaf nodes of the unencrypted key tree A as the private key to derive a public key and generate an on-chain address; the user logging into the account using the password; when the user forgets the password or logs in using a new device, the user recovers the account using the Chinese mnemonic phrase and resets the password; the user initiating a transaction on the successfully logged-in account; the user terminal correcting the recipient's on-chain address and returning the correction to the user for confirmation and transaction completion. Therefore, this invention reduces the difficulty of remembering by using a small number of short Chinese phrases with authentic semantics as mnemonic words to recover the root key.
