Problems solved by technology

[0005] However, the NFC point-to-point mode used in mobile phone NFC payment itself does not have any encryption features. Through special radio frequency equipment, NFC interaction information can be eavesdropped, causing user information leakage, so there are still some security issues in mobile phone NFC payment.

Embodiment

[0044] refer to figure 1 A mobile NFC secure payment method based on fusion and encryption of voiceprint and facial features, comprising the following steps:

[0045] 1) Image capture and voice capture: use the phone's built-in camera for image capture; use the phone's microphone for voice capture;

[0046] 2) Process the captured image and the collected voice separately: image processing includes image preprocessing, face detection, and face feature extraction to obtain face feature vectors; voice processing includes voice preprocessing and voice feature extraction to obtain voice features vector;

[0047] 3) The face feature vector and the voice feature vector are fused to obtain the feature vector P;

[0048] 4) Compress the feature vector P to 256 bytes to obtain the feature vector T;

[0049] 5) Store the feature vector T as a key in the mobile phone as the initiator, and use the Diffie-Hellman key exchange algorithm to transfer it to the target end;

[0050] 6) The c...

Abstract

The invention discloses a handset NFC safety payment method based on integrated voiceprint and face characteristic encryption. The method is characterized by comprising steps that, image acquisition and voice acquisition are carried out; the acquired image and the acquired voice are respectively processed; integrated processing on a face characteristic vector and a voice characteristic vector is carried out to acquire a characteristic vector P; the characteristic vector P is compressed to be in 256-bit bytes, and a characteristic vector T is acquired; the characteristic vector T is taken as a secret key and is stored in a handset as an initiation end, and the characteristic vector T is transmitted by utilizing a Diffie-Hellman key exchange algorithm to a target end; the characteristic vector T is taken as a symmetric secret key by two communication parties to carry out encryption communication. The method is carried out in an NFC point-to-point mode, and through the method, information safety interaction during handset NFC payment can be realized.

Description

technical field [0001] The invention relates to the field of mobile phone payment security, in particular to a mobile phone NFC (Near Field Communication, NFC for short, near field communication) security payment method based on fusion and encryption of voiceprint and facial features. Background technique [0002] The mobile phone not only has the characteristics of mobile communication anytime, anywhere, not limited by time and space, but also has the advantages of popularity, portability and personalization, which provide the basis for the mobile phone as a mobile payment terminal. The mobile wallet integrates the two high-tech products of mobile phones and bank cards, which are increasingly popular, providing people with the latest payment tools and bringing great convenience to people's daily life. [0003] NFC technology is one of the short-distance wireless communication technologies that are widely studied now, and it has the advantages of low power consumption, conve...
