Problems solved by technology

When using a smart card system on a mobile device, the PIN code is entered through the terminal keyboard, and it is easy for a third party to illegally obtain keystroke records, thereby stealing the PIN code
Even if the PIN code is encrypted and then transmitted, the key used for encryption still exists in the terminal memory, which does not guarantee that the PIN code will not be stolen

Embodiment Construction

[0088] In order to describe the technical content of the present invention more clearly, further description will be given below in conjunction with specific embodiments.

[0089] The present invention combines the identity verification requirements on mobile devices, utilizes the uniqueness of voiceprint features, uses voiceprint recognition as a means of verification, and combines the NFC function of mobile devices with smart card communication, and proposes a mobile device based on voiceprint recognition and smart card authentication method. The principle is to read the information in the smart card through the NFC function of the mobile device, encrypt the acquired voiceprint information, and send it to the server together with the smart card number, and the server will query and match, thereby solving the problem of identity verification on the mobile device. Validation problem.

Abstract

The invention relates to a system for realizing smart card authentication based on voiceprint recognition. The system comprises an authentication client and an authentication server, wherein the authentication client comprises a voiceprint sample acquisition module, a voiceprint feature extraction module and an NFC (near field communication) module; the authentication server comprises a server communicating module and a voiceprint feature matching module; the server communicating module is used for receiving authentication request information sent by the authentication client and judging the validity of the authentication request and returning to an authentication result. The invention further relates to a method for realizing the smart card authentication based on the voiceprint recognition. With the adoption of the structure of the system and the method for realizing the smart card authentication based on the voiceprint recognition, related information on a smart card can be read through an NFC function, the irreplaceable, anti-theft and anti-lost characteristics of a voiceprint are used, the authentication can be guaranteed to be finished effectively, and a wider application range is provided.

Description

technical field [0001] The invention relates to the field of legality verification of smart card holders, in particular to the technical field of voiceprint recognition, in particular to a system and method for realizing smart card identity verification based on voiceprint recognition. Background technique [0002] Smart cards or various certificates and cards with electronic chips are widely used as carriers of personal information. With the popularity of mobile devices, more and more daily activities require mobile devices to communicate with smart cards. In the traditional technology, it is generally necessary to connect an external card reader to the mobile device to realize communication with the smart card, which causes inconvenience for the user to carry and operate. As a non-contact identification and interconnection technology, NFC (Near Field Communication) provides a simple and touch-sensitive solution. It only needs to have a built-in NFC chip on the mobile devi...
