Nowadays, technology is rapidly developing in all fields, which is very important and widely used in all applications. A security system is one of these applications to avoid car theft and decrease the possibility of accidents. Enhancement of security systems in the vehicle would be beneficial to the customer to ensure safety for the customers and their families. Also, Road accidents are increasing rapidly every day. In this paper, an Integrated Vehicle Security System (IVSS) is introduced to the vehicle using many applications integrated together to increase the safety factor. A fingerprint is used in front of the vehicle door to avoid theft and face recognition is applied indoors to ignite the vehicle motor; the driver alcohol detection system is used as one of the integrated system applications which are used to prevent the drivers from driving while they are drunk and avoid any accident. All applications are connected to a GSM module to send messages to the owner in case of recognition failure either from fingerprint or face recognition with certain information and to a GPS module to give a live location of the vehicle in case it is stolen.
