To solve this problem, car manufacturers have taken many measures to develop a variety of security methods. This paper also presents a problem for such improvements. Using the body39。s unique features: fingerprint uniqueness to avoid theft, it has a high safety performance, convenience, realtime monitoring and so on. The system uses digital image processing and other related technologies, through the fingerprint feature point extraction and the fingerprint image processment, and then using fingerprint recognition algorithm for automatic fingerprint matching, since the uniqueness of fingerprints, allowing users to get much more safety, while the users do not have to carry a large bunch of keys, so that it improved portability. The system consists of hardware and software ponents, hardware includes a fingerprint image sensor, GSM module, the central processing unit and so on。 the software part are: fingerprint image capture, fingerprint matching and short message munications, and so on. First, the fingerprint image sensor gets the user’s fingerprint, then the central processor processeses the fingerprint image and matches the feature points extracted. If the fingerprint matching incorrect, the warning message will be sent to the user via GSM module. In order to achieve security and realtime monitoring of the vehicle.
