Embodiment 1

[0025] Example 1: Use 6-digit numbers instead of private keys to conduct encrypted digital currency transactions

[0026] On the client wallet software of the encrypted digital currency network, a digital watermark embedding and extraction module is installed, relying on the computer network to cooperate with the existing blockchain system to operate.

[0027] Step 1: The user runs the digital currency wallet software and enters the setting interface; enters the initial character string to generate a private key, then specifies a 6-digit mnemonic as the seed, and embeds the generated private key into the digital currency wallet through the digital watermark embedding module In the image file specified in the software;

[0028] Step 2: The user runs the digital currency wallet software and enters the account operation interface; enters the set 6-digit mnemonic to operate the account funds;

[0029] The thief runs the digital currency wallet software and enters the account oper...

Embodiment 2

[0032] Example 2: Use a password with a custom length and content instead of a private key to conduct encrypted digital currency transactions:

[0033] Install digital watermark embedding and extraction modules for digital currency wallet software, relying on computer networks to operate with existing blockchain systems.

[0034] Step 1: The user runs the digital currency wallet software and enters the setting interface; enters the initial character string to generate a private key, and then specifies a long mnemonic that is a mixture of multi-digit numbers and characters; the digital currency wallet software uses a digital watermark algorithm to help The token is the seed, and the private key is embedded into the specified image file;

[0035] Step 2: The user runs the digital currency wallet software and enters the account operation interface; enters the set long mnemonic to perform account fund operations;

[0036]The thief runs the wallet software and enters the account o...

Embodiment 3

[0038] Example 3: Use fingerprints, facial recognition and other methods instead of private keys to conduct encrypted digital currency transactions:

[0039] Install the digital watermark embedding and extraction module for the wallet software, rely on the fingerprint recognition and facial recognition software and hardware of the mobile phone, and rely on the computer network to cooperate with the existing blockchain system to operate.

[0040] Step 1. The user runs the digital currency wallet software and enters the setting interface; enters the initial character string to generate a private key, and then adds a fingerprint password or face password; embedded in the specified image file;

[0041] In the second step, the user runs the digital currency wallet software and enters the account operation interface; verifies the fingerprint or face scan, and performs account fund operations;

[0042] The thief runs the money digital currency wallet software and enters the account ...

Abstract

The invention discloses a private key storage and mnemonic method of an encrypted digital currency wallet based on a digital watermark technology, which comprises the following steps of: installing adigital watermark embedding and extracting module on client digital currency wallet software of an encrypted digital currency network, and matching with an existing blockchain system to operate by virtue of a computer network. The invention has the outstanding advantages that: the structure is simple; the method is different from a management mode of 12-24 mnemonic words of a private key in existing popular encrypted digital currency wallet software. According to the invention, a 6-bit digital mnemonic symbol is adopted; a digital watermarking technology with better hiding performance is innovatively combined; the corresponding private key is used as digital watermark recognition information; according to the method, the encrypted digital currency is embedded into the image file specifiedin the digital currency wallet software, so that the difficulty of discovering and cracking the private key is greatly improved, the memory burden of a user is effectively reduced, the safety and reliability of encrypted digital currency network transaction are ensured, and the existing bank account operation habit is not changed.

Description

technical field [0001] The invention belongs to the technical fields of financial technology, encrypted digital currency, encrypted digital currency wallet, information security and private key protection. Specifically, in the network environment, in order to facilitate the safe, reliable and low-burden use of encrypted digital currency wallets for users, a private key storage and mnemonic method for encrypted digital currency wallets based on digital watermarking technology is proposed. Background technique [0002] Encrypted digital currency is a digital currency created based on a certain encryption algorithm. Usually issued and managed by developers, accepted and used by members of a specific virtual community. Encrypted digital currencies at this stage are generally built on the basis of blockchain technology. The blockchain adopts a distributed accounting system, and its consensus mechanism is formulated by most users in the community. Its transaction information is ...
