Car anti-theft method and system based on fingerprint secret key encryption technology

Abstract

The invention relates to a car anti-theft method and system based on a fingerprint secret key encryption technology. The car anti-theft system based on the fingerprint secret key encryption technology is composed of a car key and an anti-theft control sub-system, a user sends an unlocking command on the key and inputs the fingerprint on a fingerprint collection module, a fingerprint image is converted into finger characteristic points through a fingerprinting characteristic processing module, an encryption conversion module generates a ciphertext data package through a fingerprint secret key technology, the ciphertext data package is transmitted to a data decryption module of the anti-theft control sub-system in a wireless communication mode, the data decryption module calls all the fingerprint characteristic points stored in a fingerprint characteristic repository to decrypt the ciphertext data package, a car body controller determines whether to execute a door opening operation according to received plaintext data, and an engine management unit determines whether to allow an engine to prepare for ignition according to the received plaintext data. According to the car anti-theft method and system based on the fingerprint secret key encryption technology, based on the uniqueness of the fingerprint characteristics, the fingerprint secret key encryption technology is adopted, communication safety is improved, engine ignition authority verification is added, and the anti-theft performance of the car is effectively improved.

Description

technical field [0001] The invention relates to the field of vehicle anti-theft control, in particular to an automobile anti-theft method and an anti-theft system based on fingerprint key encryption technology. Background technique [0002] In recent years, with the rapid development of my country's economy, domestic car ownership continues to increase, and car theft incidents are also becoming more and more serious. However, the existing car anti-theft solutions are mostly mechanical anti-theft, radio frequency identification anti-theft and chip electronic anti-theft, etc., with single functions and low reliability. Moreover, the current automobile manufacturers use their own unified communication keys, so that there is no certain connection between the keys and users. Once the communication keys are cracked, it is easy to cause a large number of cars to be stolen. Contents of the invention [0003] In order to further improve the vehicle anti-theft performance, the pres...
