NFC (Near Field Communication) transmission method based on biometric feature recognition

Abstract

The invention relates to an NFC (Near Field Communication) transmission method based on biometric feature recognition. A fingerprint recognition sensor is integrated into a mobile terminal, and is functionally combined with an NFC module and a Bluetooth module. The method comprises the following steps: acquiring the fingerprint information of a user by using the fingerprint recognition sensor; deciding whether the NFC module is permitted to be started or not according to the authentication result of the fingerprint recognition sensor; if an NFC function is permitted to be started according to authentication, further judging a system task; if an NFC payment activity is performed, fully handing over a task for exchanging payment information to the NFC module for finishing by a system; if the system performs data exchange activities such as tag reading / writing, starting the NFC module, rapidly activating a Bluetooth module by using the NFC module, establishing a Bluetooth transmission link, and handing over a data transmission task to the Bluetooth module for processing. By adopting the NFC transmission method, the security of payment activities and data exchange is ensured, meanwhile links are established among terminals, and the data transmission speed is increased.

Description

technical field [0001] The invention relates to an NFC transmission method based on biological feature identification, which belongs to the technical field of mobile communication. Background technique [0002] With the rapid development of information technology and the continuous updating of mobile terminals, more and more mobile terminals are equipped with NFC (Near Field Communication) modules and Bluetooth (Bluetooth) modules. NFC is a short-distance high-frequency radio technology that operates at a frequency of 13.56MHz and has a working distance of about 4cm. It can quickly establish a link between two mobile terminals, but its data transmission is slow and the transmission distance is short, which brings Communication security also leads to its shortcomings in data exchange; Bluetooth is also a radio technology for short-distance communication. It runs on 2.4Ghz ISM, with a working distance of 10m and strong data transmission capabilities. It is cumbersome, takes a...

Problems solved by technology

If a malicious program is written in the label, after the mobile terminal reads the program, the program may attack the mobile terminal, steal user information, cause user information leakage or even cause economic losses;

[0004] 2. When we use NFC to process payment services, users still need to manually account and password, which is cumbersome, time-wasting and unsafe

If you simply use the mobile terminal to simply remember the account number and password, once the mobile phone is invaded or lost by a malicious program, it will bring huge risks to the user
