specific Embodiment approach

[0034] When the hardware wallet is created,

[0035] 1) The user enters the fingerprint data through the APP terminal of the mobile phone, and allows multiple fingerprints to be input, so as to realize the function of allowing multiple people to operate the digital assets of the hardware wallet.

[0036] 2) When entering fingerprints, the mobile phone needs to be placed close to the hardware wallet, and the fingerprint data is transferred to the hardware wallet through NFC. The hardware wallet stores the incoming fingerprint data in the storage device for preservation. At the same time, the hardware wallet generates a fingerprint key based on the fingerprint data, and its own physical key to generate a private key and public key (wallet address) for transactions.

[0037] When hardware wallet transactions,

[0038] 3) The user enters the fingerprint data through the mobile APP, and the mobile APP transfers the fingerprint data to the hardware wallet.

[0039] 4) The hardwar...

Abstract

The invention discloses a hardware wallet anti-credit-card-fraud method and system based on a biological recognition technology. The hardware wallet anti-credit-card-fraud system comprises a hardwarewallet end and a smart phone end. Based on the biological recognition technology, personal biological characteristic data of a user is acquired at the smart phone APP end as a factor for generating asecret key, and the factor is transmitted into the hardware wallet through NFC, and a private key and a public key of the hardware wallet are generated, namely a wallet address, by utilizing the factor and a physical key of the hardware wallet. A user does not need to memorize a PIN code when operating the hardware wallet, so that the safety of the hardware wallet is effectively ensured, and the credit-card-fraud of the hardware wallet is prevented.

Description

technical field [0001] The invention provides a hardware wallet anti-theft brushing solution system and method based on biometric identification technology, which belongs to the technical field of private key security of encrypted currency in a materialized hardware wallet, and involves biometric identification technologies such as fingerprint identification and cryptographic technologies. Background technique [0002] With the development of blockchain technology and the popularity of cryptocurrencies such as Bitcoin, the transaction circulation of cryptocurrencies has problems such as long transaction time, high transaction fees, insufficient security and high user threshold. In order to solve the above problems, people in the industry have proposed a hardware wallet solution, the core of which is to dispose of assets through the use of private keys by users. Exist in a physical form, move the user's online digital assets offline, and directly complete the transfer of owne...
