Modern world vehicles are not just mechanical devices but are smart enough to make decisions and act based on real time inputs. This features also results in various technical vulnerabilities. So, Security systems are inevitably part of today's life. Here in the proposed work a real time vehicle security system and malware detection system developed and implemented. The proposed system will ensure that the authorized person will be able to activate and use the car and thus ensuring that unauthorized access is prevented. When the car ignition is to be activated, the security system will initially check the person's valid authentication and allow the valid user to access it. If it detects any unauthorized access, the proposed Person Authentication System (PAS) will prevent the person to operate the car and it will send the alert information image to the system controller. Also the malware system detects any spyware in the image to determine the authenticity of the image. The system is implemented integrating the hardware built on ARM core and user interface on java platform.
