Example Embodiment

[0015] The present invention will be further described below in conjunction with the drawings and embodiments.

[0016] Such as figure 1 As shown, the principle diagram of the electronic wallet system based on fingerprint encryption of the present invention is given, which is composed of a USB flash disk, which includes a housing 1, an internal flash memory chip 2, a fingerprint reader 3, and a USB interface 4; The casing 1 plays a fixed and supporting role, and the internal flash memory chip 2 is used to store electronic wallet applications, public data, private data and character password information. Public data is network block data, including all transfer records that have been confirmed on the network. This part of the data is completely public and only needs to be stored without encryption; private data includes the public key, private key and transfer records of the user's wallet. Private data needs security protection, especially the private key, which is a certificate u...

Abstract

The invention is fingerprint-encryption-based electronic purse system payment method. The setting process of an electronic purse comprises a), connecting a device and running a program; b), setting character codes; c), collecting fingerprint information; d), encrypting the fingerprint information; e), encrypting the character codes; f), generating private data files; g), completing the setting process. The payment process of the electronic purse comprises 1), device connecting including connecting an USB (universal serial bus) flash disk with a PC (personal computer), running an electronic purse application in the USB flash disk to enter a transfer process; 2) code inputting; 3) code checking; 4) acquisition of the private data files; 5) payment initiating; 6) private key decryption; 7) transfer authorization; 8) transfer record storing; 9) payment completing. According to the fingerprint-encryption-based electronic purse system payment method, by setting the character codes and the fingerprint information, payment can be completed only when the fingerprint information input during the payment process and the setting process is from the same person, so that fund security can be guaranteed.

Description

technical field [0001] The present invention relates to a payment method of an electronic wallet system based on fingerprint encryption, more specifically, to a payment method of an electronic wallet system based on fingerprint encryption that can realize mobile payment and ensure security through character passwords and fingerprint information method. Background technique [0002] Network electronic currency based on P2P protocol, such as Bitcoin, has been widely accepted and used. Users only need to have an electronic wallet (client), and they can complete operations such as collection and payment through the network. While the new technology brings convenience, it also brings new security risks to users. Although the e-wallet supports setting character passwords, when the user's e-wallet is stolen, hackers can still obtain the user's payment password and steal funds through brute force cracking, Trojan horse monitoring and other means. This makes it difficult for such ...
