Digital currency wallet based on electrocardiosignal identity authentication

Abstract

The invention discloses a digital currency wallet based on electrocardiosignal identity authentication. The digital currency wallet comprises electrocardio lock hardware and an electrocardio lock wallet APP; the electrocardio lock hardware is automatically waken up when a user opens the electrocardio lock wallet APP to perform digital currency transaction, the electrocardio lock hardware continuously collects the electrocardiosignal of the user, preprocesses the electrocardiosignal and the transmits the same to the electrocardio lock wallet APP; the electrocardio lock wallet APP performs the feature extraction on the electrocardiosignal after completely checking the same, and performs the electrocardio identity identification by using the feature; if the feature is matched with the uniqueuser electrocardio ID stored when the electrocardio lock wallet APP is used as the first time, the verification is passed, and the user can continue the currency transaction operation; and the electrocardio lock wallet APP can continuously perform electrocardio identity authentication on the real-time electrocardiosignal collected by the electrocardio lock hardware worn by the user at fixed time in the currency transaction period, and the digital currency wallet operation can be prohibited when the electrocardio identity authentication in any period is not passed. The system disclosed by the invention greatly improves the security of the digital currency transaction at a user-side through the electrocardiosignal identity authentication.

Description

technical field [0001] The invention relates to the field of digital currency wallets, in particular to a digital currency wallet based on electrocardiographic signal identity authentication. Background technique [0002] Currently, digital currency wallets based on blockchain technology can be classified into: web wallets, multi-signature wallets, desktop wallets and mobile wallets. The address (public key) and private key of the user account are generated by the elliptic algorithm and stored in the digital currency wallet file, and the private key is encrypted and decrypted by the digital currency wallet client software. Due to the decentralization and anonymity of the entire digital currency system, once the digital currency wallet is lost, the digital currency stored in all addresses in the digital currency wallet may be stolen, and once stolen, it cannot be retrieved. Therefore, the security of digital currency wallets is extremely important. [0003] Although the enc...

Problems solved by technology

[0003] Although the encryption mechanism of the current digital wallet APP can ensure that the user re-imports the wallet and resets the payment password in time to avoid the loss of digital property when the user realizes that the mobile phone is lost, etc., this mechanism cannot prevent the digital property from being stolen by someone trusted by the user. It is also impossible to avoid the risk that the mobile phone is stolen when the user is not awake and the user cannot reset the payment password in time
