SMS-Based Offline Mobile Device Security System

Mobile Device Security is an important factor as all the user's sensitive information is stored on the mobile device. The problem of mobile devices getting lost or stolen has only been increasing. There are various systems which provide Online Mobile Device Security which require internet to perform their required functions. Our proposed system SMS Based Offline Mobile Device Security System provides mobile device users with a wide range of security features that help protect the mobile device from theft and also acts as an assistant that helps the users in any problems they may face in their day-to-day lives. The project aims to develop a mobile security system that will allow the user to manipulate his mobile device from any other device through SMS which can be used to get contact information from the user's mobile device remotely, help find the phone by maximizing the volume and playing a tone, trace the current location of the mobile device, get the IMEI No of the device, lock the device, send a message that will be converted to speech and played on the user's mobile device, call forwarding, message forwarding and various other features. It also has an additional security feature that will detect a sim card change and send the new SIM card mobile no to the recovery mobile numbers specified during initial setup automatically. Hence, the user will be able to manipulate his phone even after the SIM card has been changed. Therefore, the SMS-Based Offline Mobile Device Security System provides much more security for the mobile device than the existing online device security methods.
