Balamurugan ** ABSTRACT In this modern era of science and technology people depend on technologies than referring to people for any instance. People rely on Smartphone and applications for any gathering of information on any details such as locations, routes, alerts, and so on. But so far end-user needs to install multiple applications for each function such as location, route and alert. Hence the app (aka application) entitled “Route Saver” which is built user-friendly synchronizing all the functions in one application such as location-distant finder, route analyzer, alert generator and contact holder. Each module is developed in a unique way with innovative specialties. First, the query for route request is processed using route APIs to provide all potential navigation paths, which the user can choose based on the priorities on mode of travel. Then, the dynamic mapping of location-based services (e.g., restaurants, tourist attractions) can be used to reduce the manual querying need of the users significantly. Also, the alert module helps to inform the position of the app user to concerned people(s). Furthermore, the user is given the option to check and/or provide review of the points-of-interest requested during search. The experimental evaluation shows that the application achieves high accuracy to pointing out places dynamically with precision. Keywords: Watermarking, Haar Wavelet, DWT, PSNR I. INTRODUCTION A Smartphone is a mobile phone with an advanced mobile operating system which combines features of a personal computer operating system with other features useful for mobile or handheld use. It combines many features such as media player, GPS navigation unit and so on into a single device. The Global Positioning System (GPS) is a space-based navigation system that provides location and time information in all weather conditions, anywhere on or near the Earth where there is an unobstructed line of sight to four or more GPS satellites. The GPS concept is based on time and the known position of specialized satellites. GPS satellites continuously transmit their current time and position. A GPS receiver monitors multiple satellites and solves equations to determine the exact position of the receiver and its deviation from true time. A GPS navigation device is a device that accurately calculates geographical location by receiving information from GPS satellites. Some of the features of a GPS device are display location in maps in graphical format, turn-by-turn navigation directions via text or speech, traffic congestion maps and suggesting alternative directions, and information on nearby amenities such as restaurants, tourist attractions and such. Location-based services (LBS) are a general class of computer program-level services that use location data to control features. Location-based services use real-time geo-data from a mobile device or Smartphone to provide information, entertainment or security.
